Zbot spreads thru fake email ...
January 13, 2012 - "... malicious SPAM campaign that is actively sent out by the Cutwail spam botnet. The suspicious email claims to be a bill summary from the New York-based energy company Con Edison, Inc. It may use the subject line “ConEdison Billing Summary as of <DATE>” and the attachment uses the filename format Billing-Summary-ConEdison-<random numbers>-<Date>.zip... The attached zip file contains an executable file, which unsurprisingly is a Zbot malware variant. When extracted, the malicious executable uses no disguise. It uses no fake icons of Adobe Reader or Microsft Word, no double file extensions, or excessive use of space in the file name to hide the .EXE extension... bill notifications do -not- usually arrive with an executable file - so emails like this should be treated with extreme suspicion. When you see these obvious signs of malware, just stop and delete the email..."

January 16, 2012 - "... Zappos.com is advising over 24 million customers to change their passwords following a data breach... Zappos employees received an email from CEO Tony Hsieh on Sunday*, alerting them about a security breach that involved the online shop's customer database... Even though he assured everyone that no credit card details had been compromised, Hsieh revealed that the attacker had accessed customer records including names; email, billing and shipping addresses; phone numbers, and the last four digits of their credit card numbers. The hacker also gained access to password hashes for the accounts registered on the website, prompting the company to reset everyone's access codes.

This new attack is specifically designed to circumvent post transaction fraud prevention measures... Some Post-Transaction Attacks are not targeted at the bank but rather at the user. One example uses SpyEye to execute man in the browser (MitB) attacks that hide confirmation emails in web email services or fraudulent transactions on the online banking site... these attacks can bring the entire fraud assessment process to a grinding halt..."

Some of these websites are well-known... While we cannot be certain exactly what sort of scams may appear, keep in mind that the websites listed above will resume normal activity around their announced times. It is unlikely they will resume much earlier, and some may even be slightly delayed in returning to normal activity. If you see any pronouncements about sites returning to operation early or an option to bypass the blackout by visiting a new web site, ignore them and wait for the site to return at its preannounced time: The “new” site being promoted may have far more malicious actions in mind than pictures of kittens, discussions about ents, bacon and narwhals or jokes about arrows to the knee..."

It could be assumed that such a succinct, yet true, statement should yield, in return, an equally concise solution. In fact, it provides only a place to start... The aim is to encourage service providers to "clean up" and to be proactive in stopping the cybercriminal activities found on their servers... Some things have changed since our early reports. There is now more cooperation between the security industry, law enforcement and service providers and some pleasing results against some of the worst activities found on the net. Sadly, some things have -not- changed. Cybercriminals are still too easily making financial gain from the lax procedures by service providers, security vulnerabilities of organizations large or small and Internet users’ lack of awareness. 2011 showcased some data breaches of truly epic proportions with the year ending in the same vein in which it began..."

Nevertheless, TLD .su (... operated by RIPN) is still active today which means that people can still register domain names with that TLD. As of today I’m seeing an increasing number of malicious .su domains being used by botnet herders. In fact this means that the criminals seem to be switching from .ru to .su ...

* Update 2012/02/06: After obtaining access to logs and PHP files from compromised Web servers, further analysis indicates that most of the compromised Web sites were running older versions of WordPress, but they were not all running 3.2.1. The attackers’ exact point of entry is uncertain. At first, we suspected vulnerable WordPress plugins, because a subset of analyzed sites were running vulnerable versions of the same WordPress plugins. Now that we have access to data from several compromised Web servers, the logs show us that, in some cases, the point of entry was compromised FTP credentials. In several instances, once attackers had access, they scanned WordPress directories and injected specific files (e.g., index.php and wp-blog-header.php) with malicious PHP code.
WordPress exploit in-the-wild for v3.2.1 sites ...
30 Jan 2012 - "... site was compromised because it was running an old version of Wordpress (3.2.1) that is vulnerable to publicly available exploits... more interesting is the redirection chain and resulting exploit site... From our analysis the number of infections is growing steadily (100+)... The Java exploit being served is CVE-2011-3544* (Oracle Java Applet Rhino Script Engine Remote Code Execution), which most Exploit Kits adopted in December 2011 because it is cross-platform and exploits a design flaw. Normally, kits use a variety of exploits... regardless of what OS or browser we used for testing, this Exploit Kit attempted to exploit ONLY our Java Runtime Environment (JRE). It did not attempt -any- other exploit... Websense... has found 100+ compromised Web sites, all with similar infection characteristics. The compromised Web sites all share these traits:
> Running WordPress 3.2.1
> Force a drive by download via iframe to the same malicious set of domains hosting a PHP Web page in the form of:
[subdomain] .osa .pl/showthread.php?t=.*
> Attempt exploitation using CVE-2011-3544
If exploitation is successful, ( the Tdss rootkit will be installed ) on the user's machine.
If you're running WordPress 3.2.1, we recommend that:
You upgrade to the latest stable version of WordPress**.
Check the source code of all your Web pages to see if you've been infected (see the code above). If you have been infected, be sure to upgrade WordPress while simultaneously removing the injected code so that your Web pages aren't simply being reinfected after being cleaned.

Malware redirects bank phone calls to Attackers
Feb 01, 2012 - "... some new Ice IX configurations that are targeting online banking customers in the UK and US. Ice IX is a modified variant of the ZeuS financial malware platform. In addition to stealing bank account data, these Ice IX configurations are capturing information on telephone accounts belonging to the victims. This allows attackers to divert calls from the bank intended for their customer to attacker controlled phone numbers. We believe the fraudsters are executing fraudulent transactions using the stolen credentials and redirecting the bank’s post-transaction verification phone calls to professional criminal caller services (discussed in a previous Trusteer blog*) that approve the transactions. In one attack captured by Trusteer researchers, at login the malware steals the victim’s user id and password, memorable information/secret question answer, date of birth and account balance. Next, the victim is asked to update their phone numbers of record (home, mobile and work) and select the name of their service provider from a drop-down list. In this particular attack, the three most popular phone service providers in the UK are presented: British Telecommunications, TalkTalk and Sky... To enable the attacker to modify the victim’s phone service settings, the victim is then asked by the malware to submit their telephone account number. This is very private data typically only known to the phone subscriber and the phone company. It is used by the phone company to verify the identity of the subscriber and authorize sensitive account modifications such as call forwarding. The fraudsters justify this request by stating this information is required as a part of verification process caused by "a malfunction of the bank’s anti-fraud system with its landline phone service provider"... As we discussed in a recent blog**, fraudsters are increasingly turning to these post-transaction attack methods to hide fraudulent activity from the victim and block email and phone communication from the bank. This allows attackers to circumvent security mechanisms that look for anomalies once transactions have already been executed by the user..."

Mobile malware from German svr... 1,351 sites
Feb 7, 2012 - "... recently found a server that hosts a great number of sites that are used to launch mobile malware, targeting Android OS and Symbian (specifically the J2ME platform). The server, located in Germany, is managed by a hosting provider known as a haven for cyber criminals. We found a total of 1,351 websites hosted on the said server and categorize the sites into five segments based on the type of guise they use for the distributed malware:
Android Market apps
Opera Mini/ Phone Optimizer apps
Pornographic apps (sites were unavailable during time of checking)
App storage sites
Others (sites that were inaccessible during time of checking)...

They feature popular applications like WhatsApp, Facebook, Facebook Messenger, Barcode Scanner, Skype, Google Maps, Gmail, YouTube, and others. The files downloaded from such sites are now detected as ANDROIDOS_FAKENOTIFY.A... the sites that feature download links for Opera Mini and Phone Optimizer lead to J2ME_SMSSEND.E - a malware that can run on devices that support MIDlets... Among all the categories mentioned, most of sites promoted Opera Mini updates and Photo Optimizer Apps compared with others.. the attackers are not necessarily targeting only one platform... we also saw that cybercriminals use different social engineering lures.

Last month saw malware attacks targeting a wide range of potential victims, including gamers looking for a Pro Evolution Soccer 2012 game crack, small business owners concerned about the reputation of their business, and government organizations receiving spoofed messages from the United States Computer Emergency Readiness Team (US-CERT)... malware writers installing rootkits on the systems of gamers who were looking for a pirated release of Pro Evolution Soccer 2012... scammers also latched onto the buzz surrounding the upcoming fourth installment of the Halo® video game series... by offering bogus beta invites in return for filling out surveys and recommending links on Facebook and Google+. These attacks leverage the popularity of these titles among the gaming community and are meant to take advantage of the mistakes some users might make when acting out of excitement about a favorite game franchise... phishing emails posing as notices from the Better Business Bureau, claiming that a customer had filed a complaint against the recipient. The messages contained links to malware created using the Blackhole exploit kit. Government body US-CERT served as another disguise for cybercriminals attempting to bait unwitting victims into opening a file that contained a variant of the Zeus/Zbot Trojan. Meanwhile, Tumblr users were baited with “free Southwest Airlines tickets” in exchange for taking surveys and submitting personal information by a phony “Tumblr Staff Blog.” Malware writers and internet scammers also sought to attack a wider cross-section of the population when opportunities presented themselves to creatively piggyback on hot news topics and highly trafficked websites. This past month, the shutdown of popular file hosting website Megaupload led to a domain typo scam targeting both the regular users of the website as well as visitors who were interested in seeing the FBI notice posted on the site.

Greyware fog ...
Feb 13, 2012 - "... it was more than a little bit surprising when we observed downloads from Download.com behaving like spyware... Download.com had begun delivering freeware downloads in a wrapper that enticed users to click during the install in order to receive special offers and deals... When a user clicked on this option, the application took several steps that lowered the security of the user’s system, such as making changes to the security settings in the browser, changing proxy settings and also installed a service that leaked user information over HTTP POSTs. As it turns out, Download.com was under new management and had then intentionally developed this wrapper with those functions as a method to collect shopping data from their users. This led to a miniature scandal as antivirus vendors began rightly classifying the code as spyware, and Download.com then quickly reversed course. However, this is an example of a very broad problem... there are tons of applications and code out there that are not overtly malicious, yet do very spyware-like things without the user’s knowledge. Changes to security settings, browser settings, listening on backdoor ports, changing personal firewall settings. This is dangerous because it is -unlikely- that this type of behavior is going to be flagged as malicious, and yet it is materially reducing the security posture of the client machine. These things don’t compromise the host directly, but it certainly softens up the target for more malicious code or attackers... we will need to the ability to quickly determine which sorts of downloads and applets are safe for users to download in just the same way we are safely enabling applications today, applications such as webmail, SharePoint and other collaborative apps. Anything that affects the security posture of the client or the network needs to be seen by IT, and IT needs the policies in place that clearly define what sorts of behavior are allowed and which are not. The lesson here is that until we gain a credible level of control here in the grey end of the spectrum, we are simply trusting the Internet to provide reasonably safe code that doesn’t endanger users..."

Fake AICPA e-mail - Blackholes and Rootkits ...
Feb 20, 2012 - "Be wary of emails claiming to be from AICPA – as per their alert here*, these are not real and any mention of “unlawful tax return fraud” is just a bait to convince the end-user to open up a malicious attachment (in this case, a .doc file** although there are rogue PDF files in circulation too). As with many of the malicious spam campaigns doing the rounds at the moment, this one will use the Blackhole exploit kit to serve up zbot from multiple compromised domains. Worse, a Sakura kit (typical example here***) will download Sirefef / ZeroAccess , which as we’ve seen elsewhere**** is not a good thing to have on your system. One of the more unpleasant spam campaigns we’ve seen recently."

"Summary: A variety of security patches are released for Cisco NX-OS, Adobe Flash Player, and Java. Such third party software is often the vector used by attackers to compromise systems and install malware. Database systems are also compromised and recent data leaks point to the importance of protecting databases with basic security measures and encryption... The threat of a DNS attack on March 31st* may not be as deadly as it seems, and the trend of users bringing their own devices to work can pose grave risks to security."

TL;DR: ICS ASLR = FUBAR ...
22 Feb 2012 - "Jon Oberheid has found the ASLR (Address Space Layout Randomisation) in Google's Android 4, Ice Cream Sandwich (ICS), somewhat wanting. In a detailed posting on the Duo Security blog*, one commenter eloquently concluded that "TL;DR: ICS ASLR = FUBAR". Specifically, he found that the lack of randomisation in executable and linker memory regions meant that it would be "largely ineffective for mitigating real-world attacks"... The Android Security Team responded to Oberheid's posting noting that they will, in 4.0.3, randomise the heap and future Android releases will randomise the linker and executable mappings."

McAfee Q4 Threats Report...
Feb 21, 2012 - "... The overall growth of PC-based malware actually declined throughout Q4 2011, and is significantly lower than Q4 2010. The -cumulative- number of unique malware samples in the collection still exceeds the 75 million mark. In total, both 2011 and the fourth quarter were by far the busiest periods for mobile malware that McAfee has seen yet, with -Android- firmly fixed as the largest target for writers of mobile malware. Contributing to the rise in malware were rootkits, or stealth malware. Though rootkits are some of the most sophisticated classifications of malware, designed to evade detection and “live” on a system for a prolonged period, they showed a slight decline in Q4. Fake AV dropped considerably from Q3, while AutoRun and password-stealing Trojan malware show modest declines. In a sharp contrast to Q2 2011, Mac OS malware has remained at very low levels the last two quarters.
Web Threats: In the third quarter McAfee Labs recorded an average of 6,500 -new- bad sites per day; this figure shot up to -9,300- sites in Q4. Approximately one in every 400 URLs were malicious on average, and at their highest levels, approximately one in every 200 URLs were -malicious-.

Failing that, the malicious applet displays a self-signed certificate (claiming to be from Apple) in the hope users just install the malware. Once snugly in place, the malware attempts to capture the login credentials users enter on bank websites, PayPal, and many others. OS X Lion did not come with Java preinstalled, but Snow Leopard does, so users of Mac's latest OS are more at risk of attack. Mac security specialist Intego warns that the variant is infecting Mac users and spreading in the wild.

Cybercriminals target phones - Android 'most exposed'
Feb 28, 2012 AFP - "Cybercriminals are sneaking a fast-increasing amount of malware into smartphones to steal data or even money, with those running on Google's Android most exposed to security threats, analysts said... Anyone can create or install an application on an Android phone... as opposed to the Apple controlled Appstore which imposes a layer of screening... Trend Micro surveyed independent analysts about security features on the four main mobile operating systems - Apple's iOS, RIM's BlackBerry, Microsoft's Windows and Google's Android - and found that Blackberry was ranked most secure and Android the least. BlackBerry benefitted from the fact that it was originally designed more as a platform than a device, while iOS, ranked second most secure, was tightly controlled by Apple... Technology company Juniper Networks compiled a "record number of mobile malware attacks" in 2011, particularly on Android phones. In 2010, just 11,138 mobile malware samples were recorded, but they soared 155 percent to 28,472 in 2011, the company said. Just under half - 46.7 percent - occurred on Android phones, said Juniper, whose study did -not- look into Apple breaches... Some criminals are hiding "malicious code in legitimate applications" that consumers are downloading unwittingly. Once they have gained access to data on the phone, they are stealing information that could be used in identity theft or in illegal transactions. A further incentive for cybercriminals to breach smartphone security is that unlike computers, each phone "has a direct link to money" through the SIM card... Criminals are able, for instance, to implant so-called trojan horses that prompt phones to send SMSes to premium numbers..."

Olympic phishing messages...
01 Mar 2012 - "... Websense... detected and tracked a significant number of these kinds of Olympic phishing messages whose goal is to entice users to submit their personal information... the well-known "National Lottery"-type scam, where the targeted users are tricked into believing they are winners of some sort of local lottery... Once the user opens the Microsoft Word document, the sender informs the user that he or she is the lucky "winner" of £200,00.00 GBP, and then requests that the user provide personal information, such as full name, address, nationality, occupation, and mobile number to help process the claim... Although this email attachment is not malicious, it is clear that the sender has some other questionable activity in mind by asking for and collecting personal information. This could range from email spam using the victim's email address and mobile phone number to other rogue promotional messages that could potentially have web links leading to malicious websites. Threats like these Olympics scams are also known as advanced-fee fraud in which victims are asked to contact a claims agent. They may then be asked to pay "processing fees" to receive their money, which never happens... This is also a good way to collect, with social engineering techniques, mobile phone numbers and to start other kinds of fraudulent activities like asking for details about mobile banking accounts..."

Employees disabling security controls
29 Feb 2012 - "Corporate mobile devices and the bring-your-own-device (BYOD) phenomenon are rapidly circumventing enterprise security and policies, say the results of a new global study sponsored by Websense... 77 percent of more than 4,000 respondents in 12 countries agree that the use of mobile devices in the workplace is important to achieving business objectives, but only 39 percent have the necessary security controls to address the risk their use entails. According to a previous Ponemon Institute survey, IT respondents said 63 percent of breaches occurred as a result of mobile devices, and only 28 percent said employee desktop computers were the cause. This latest research shows that organizations often don't know how and what data is leaving their networks through non-secure mobile devices, and that traditional static security solutions are not effective at stopping advanced malware and data theft threats from malicious or negligent insiders... More than 4,600 IT and IT security practitioners in Australia, Brazil, Canada, France, Germany, Hong Kong, India, Italy, Mexico, Singapore, United Kingdom, and the United States were surveyed. With an average of 10 years' experience in the field, fifty-four percent are supervisors (or above) and 42 percent are from organizations with more than 5,000 employees.

Verizon Investigative Response Caseload Review
Feb 29, 2012 - "Verizon -2011- Investigative Response (IR) Caseload Review* is a preview of their pending larger Data Breach Investigations Report (DBIR).
Analysis: This report indicates that outside attacks towards servers comprise the largest source of data breach incidents. Financial gain continues to be a motive, however increasing amounts of hacktivism accelerates data breach trends. System penetration and malware are the highest threats, with default and weak passwords and backdoor tools being the highest vectors. 90% of organizations were alerted by an outside organization, pointing to the fact that internal monitoring systems, if used, were not as useful. Encryption can help reduce the pain of a data breach incident, but much sensitive data is not properly encrypted."
(Info below from linked PDF report at URL above - pg. 5)
Top 10 threat action varieties by number of breaches
Hacking - Exploitation of default or guessable credentials - 29%
Malware - Backdoor (allows remote access / control) - 26%
Hacking - Use of stolen login credentials - 24%
Hacking - Exploitation of backdoor or command and control channel - 23%
Malware - Keylogger / Form-grabber / Spyware (capture data from user activity) - 18%
Malware - Send data to external site / entity - 17%
Malware - System / network utilities (PsTools, Netcat) - 14%
Hacking - SQL Injection - 13%
Malware - Capture data resident on system (e.g., cache, disk) - 9%
Malware - Download / install additional malware or updates - 9% ...
"... Among servers involved in breaches in our 2011 cases, point-of-sale servers, web/application servers, and database servers led the pack. Desktops, laptops, and point-of-sale terminals comprised the bulk of compromised end-user devices.
With respect to the data stolen from these assets, criminals got away with a mixed bag. Payment cards, personal information, and authentication credentials were most often compromised, but other types of sensitive organizational data, trade secrets, and copyrighted information were taken..."

Flashback Mac -malware- using Twitter as C&C center
Mar 5, 2012 - "... Flashback... uses an interesting method of getting commands: it uses Twitter. And rather than use a specific Twitter account, which can be removed, it queries Twitter for tweets containing specific hashtags. These hashtags aren’t as simple as, say, #Flashback or #MacMalwareMaster, but are seemingly random strings of characters that change each day. Intego’s malware research team cracked the 128-bit RC4 encryption used for Flashback’s code and discovered the keys to this system. The hashtags are made up of twelve characters. There are four characters for the day, four characters for the month, and four characters for the year... In addition, in order to ensure that people checking logs don’t spot the malware, it uses a number of different user agents... It’s worth noting that the people behind the Flashback malware most likely to not send commands every day, and certainly delete their tweets, as Intego has found no past tweets in its searches. However, the malware clearly sends these HTTP requests, looking for such tweets..."

A few months ago, Japanese users were also hit by ransomware in a one-click billing fraud scheme targeted for Android smartphones... the more recent ransomware variants appear to be targeting other European countries. They are disguised as notifications from country-specific law enforcement agencies such as eCops of Belgium and Bundespolizei of Germany... a majority of the top eight countries infected with ransomware are from Europe:
... While ransomware are also being distributed through affiliate networks like FAKEAVs, these attacks operate using payments outside of traditional credit card payments, specifically via Ukash and Paysafecard vouchers. Ukash and Paysafecard are widely used online payment methods that do not require personal details. Such level of anonymity has naturally earned the attention of cybercriminals and, as we can see, is now being abused for the ransomware business... based on feedback taken from the past 30 days."

Police Themed Ransomware continues
April 4, 2012 - "Over the last several weeks, we've been monitoring a rash of ransomware campaigns across Europe, in which messages, supposedly from the local police, are displayed demanding that a fine must be paid in order to unlock the computer... easiest way to manually disable it is as follows:
1 – Press Ctrl-O (that's the letter O, not the number zero).
2 – Select "Browse", go to c:\windows\system32 and open cmd.exe.
3 – Type "explorer.exe" into the newly opened window. You should now be able to use the desktop again.
4 – Browse to your Startup folder. The path will vary depending on the language settings and Windows version. The screenshot below shows the path on the English version of Windows XP. You will also have to replace "Administrator" with your user name in the path (unless you're already using the Administrator account, but lets not get started on that…).
5 – Delete any entries you don't recognize. The names of the malicious entries may be different than the ones shown in the screenshot. If you are unsure, you can remove all entries, but at the risk of disabling other valid applications from automatically starting.
6 – Reboot the computer.
After this the threat is disabled but malicious files still remain on the computer. Scanning the computer with an antivirus product is highly recommended.
The steps may vary slightly depending on the variant... Microsoft provides information in their description*.
Updated to add on April 5th: Our description for Trojan:W32/Reveton includes removal instructions."

Mobile phones - weak link in Online Bank Fraud scheme
March 13, 2012 - "... two online banking fraud schemes designed to defeat one time password (OTP) authorization systems used by many banks... in these -new- scams the criminals are stealing the actual mobile device SIM (subscriber identity module) card...
> In the first attack, the Gozi Trojan is used to steal IMEI (international mobile equipment identity) numbers from account holders when they login to their online banking application. The bank is using a OTP system to authorize large transactions. Once they have acquired the IMEI number, the criminals contact the victim’s wireless service provider, report the mobile device as lost or stolen, and request a new SIM card. With this new SIM card, all OTPs intended for the victim’s phone are sent to the fraudster-controlled device...
> The second attack combines online and physical fraud to achieve the same goal. We discovered this scheme in an underground forum. First, the fraudster uses a Man in the Browser (MitB) or phishing attack to obtain the victim’s bank account details, including credentials, name, phone number, etc. Next, the criminal goes to the local police department to report the victim’s mobile phone as lost or stolen. The criminal impersonates the victim using their stolen personal information (e.g., name, address, phone number, etc.). This allows the fraudster to acquire a police report that lists the mobile device as lost or stolen. The criminal then calls the victim to notify them that their mobile phone service will be interrupted for the next 12 hours. In the meantime, the criminal presents the police report at one of the wireless service provider’s retail outlets. The SIM card reported as lost or stolen is -deactivated- by the mobile network operator, and the criminal gets a new SIM card that receives all incoming calls and OTPs sent to the victim’s phone number. This allows the fraudster authorize the fraudulent transactions he/she executes...
Since accounts protected by OTP systems typically have higher transfer limits and are less scrutinized, they are more lucrative. This explains why criminals are willing to go to great lengths to gain access to them. The one common thread in both schemes is that they are made possible by compromising the web browser with a MitB attack to steal the victim’s credentials. By combining stolen personally identifiable information with clever social engineering techniques, criminals using these attacks don’t need to trick users into verifying fraudulent transactions. They are able to bypass out of band authentication mechanisms like SMS-delivered OTPs by authorizing these transactions themselves."

The administrator leaves the default “admin” user name and chooses a simple password, and -never- changes it... There is a technique known as brute-force attack... access is gained to your environment through brute force. Often conducted by bots, these attacks will run through a compiled list of common passwords and their permutations (i.e., password, Pa$$w0rd, p@ssw0rd, etc..)... the attackers know that you substitute ‘A’ for an ‘@’ and ‘S’ for a ‘$’. Using this method the attackers are gaining access to your wp-admin, this then allows them to serve spam via your posts, deface your home page like we recently saw with ServerPro, and inject any one of the other types of malware... in the last few days we detected more than 30 IP addresses trying to guess the admin password on our test WordPress sites (wp-login.php).

... Android malware continues with multi-factor financial credential theft and remote update capabilities.
Analysis: As mobile devices proliferate, cybercrime goes where the money is. While the style of this attack is not new, extra capabilities are being seen and it is likely just a matter of time before very sophisticated malware targeted towards mobile devices becomes a larger problem. Additionally, malware awareness and safe browsing on handhelds may not be as common as on dekstop or notebook systems in enterprises with security policies. If mobile devices are not yet part of the organizational security policy, such threats may quicken this change.

Already, "spear phishing" techniques involving trickery and sometimes 0-day exploits are finding many victims, and this trend is likely to increase."

2012 Data Breach Investigations Report - Verizon
March 22, 2012 - "... The report combines data from 855 incidents that involved more than 174 million compromised records, an explosion of data loss compared to last year’s 4 million records stolen. The increase is due largely to the massive breaches perpetrated by activists... Most breaches Verizon tracked were opportunistic intrusions rather than targeted ones, occurring simply because the victim had an easily exploitable weakness rather than because they were specifically chosen by the attacker. And, as with previous years, most breaches — 96 percent — were not difficult to accomplish, suggesting they would have been avoidable if companies had implemented basic security measures. Verizon noticed a difference between how large and small organizations are breached. Smaller organizations tend to be breached through active hacking, involving vulnerabilities in websites and other systems and brute force attacks. Larger companies are more often breached through social engineering and phishing attacks — sending e-mail to employees to trick them into clicking on malicious attachments and links so that the intruders can install malware that steals employee credentials. Verizon surmises that this is because larger organizations tend to have better perimeter protections, forcing intruders to use human vulnerabilities to breach these networks instead."

Critical Java hole being exploited on a large scale ...
Severity: High Severity
Published: Wednesday, March 28, 2012 19:20
Java security vulnerability patched in February is now being used widely by criminals to install malware.
Analysis: Patch! Watch for outdated Java on the network as the presence of old Java User-Agents is often a sign that a system has been exploited and Java is now doing the attackers bidding, typically downloading something evil.

MacOS X targeted w/MS Office exploit in the wild...
March 27, 2012 - "... The doc files seem to exploit MS09-027 and target Microsoft Office for Mac. This is one of the few times that we have seen a malicious Office file used to deliver malware on Mac OS X... An attacker who successfully exploits this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
> When the victim opens the malicious Word file using Office for Mac, the shellcode writes the malicious payload on disk and executes it, and then opens a benign office file... The C&C server this time is:
- 2012 .slyip .net: 18.104.22.168
22.214.171.124 – 126.96.36.199
Black Oak Computers Inc – New York – 75 Broad Street...
> The second trojan found is a new one never seen. We have found several versions compiled for different architectures (ppc, i386..). We have also found a version that has paths to debugging symbols... The C&C domain resolves to:
- freetibet2012 .xicp .net: 188.8.131.52
184.108.40.206 – 220.127.116.11
China Unicom Beijing province network...
All the samples we have found have 0/0 rate antivirus detection, it includes the malicious doc files..."
March 29, 2012 - "... These Word documents exploit a Word vulnerability that was corrected in June, 2009, but also take advantage of the fact that many users don’t update such software. Word 2004 and 2008 are vulnerable, but the latest version, Word 2011 is not. Also, this vulnerability only works with .doc files, and not the newer .docx format..."

Blackhole exploits ...
April 2, 2012 - "... an exploit for CVE-2011-0559*, which is one of the two Flash exploits being used by Blackhole currently. Compared to other exploits, this one has been used by Blackhole for quite some time and yet the coverage using different security products is very low**.
With very -low- antivirus coverage, -no- Metasploit module, and PoCs being extremely difficult to find, this increases the chances of exploitation. Blackhole targets to exploit Adobe Flash 10.0 and earlier versions, 10.1, and 10.0.x (where x is later than 40). The vulnerability has been patched since March 2011. Detection has been added to F-Secure Anti-Virus as Exploit:W32/CVE-2011-0559.A..."

Android bot attacks rooted smartphones
3 April 2012 - "Antivirus company NQ Mobile has discovered a variant of the DroidKungFu Android malware called DKFBootKit* that targets users who have rooted their smartphones. The malware piggybacks on apps that would otherwise ask for root privileges anyway – and, once the user has agreed, sets up camp deep in the smartphone's boot sequence and replaces commands such as ifconfig and mount to help ensure it is started early in the boot sequence..."
"... DKFBootKit makes use of the granted root privilege for other malicious purposes, namely comprising the system integrity... the malware itself contains a bot payload that phones home to several remote C&C servers and waits for further commands...
1) Only download applications from trusted sources...
2) Never accept application requests from unknown sources...
3) Be alert for unusual behavior on the part of mobile phones and be sure to download a trusted security application that can scan the applications being downloaded onto your mobile device..."

Credit Card fraud/malware attacks Facebook users
April 03, 2012 - "... new configuration of the Ice IX malware that attacks Facebook users after they have logged in to their account and steals credit card and other personal information... discovered a “marketing” video used by the creators of the malware to demonstrate how the web injection works. The global reach and scale of the Facebook service has made it a favorite target of fraudsters... This latest attack uses a web injection to present a fake web page in the victim’s browser. The form requests the user provide their cardholder name, credit/debit card number, expiry date, CID and billing address. The attackers claim the information is needed to verify the victim’s identity and provide additional security for their Facebook account... This pop up* presents virtually the same message used in the Ice IX configuration our researchers discovered and analyzed. The only difference is the version in the video requests a social security number and date of birth, in addition to the information mentioned earlier... We contacted Facebook to advise them that they would be mentioned in this blog. Facebook requested that we pass on some information about their site’s security measures. Here’s a summary of their response:
i) Facebook actively detects known malware on users' devices to provide Facebook users with a self-remediation procedure including the Scan-And-Repair malware scan. To self-enroll in this check point please visit – on.fb.me/AVCheckpoint
ii) Please advise your readers to report to Facebook any spam they find on the Facebook site, and remember Facebook will never ask for your credit card, social security, or any other sensitive information other than your username and password while logging in."
