    Thumbs down Gumblar authors crash WordPress sites

    FYI...

    Gumblar authors crash WordPress sites
    - http://www.networkworld.com/news/200...s.html?hpg1=bn
    11/04/2009 - "Webmasters who find an annoying error message on their sites may have caught a big break, thanks to a slip-up by the authors of the Gumblar botnet. Tens of thousands of Web sites, many of them small sites running the WordPress blogging software, have been broken, returning a "fatal error" message in recent weeks. According to security experts those messages are actually generated by some buggy malicious code sneaked onto them by Gumblar's authors... Gumblar's authors apparently made some changes to their Web code... and as a result "the current version of Gumbar effectively breaks WordPress blogs"*... WordPress sites that have crashed because of the buggy code display the following error message: Fatal error: Cannot redeclare xfm() (previously declared in /path/to/site/index.php(1) : eval()'d code:1)
    in /path/to/site/wp-config.php(1) : eval()'d code on line 1
    Other sites running software such as Joomla get different fatal-error messages... In effect, the messages warn Gumblar's victims that they've been compromised..."

    Thumbs down Gumblar malware domain reactivated

    FYI...

    Gumblar malware domain reactivated
    - http://blog.scansafe.com/journal/200...s-baaaack.html
    November 5, 2009 - "... some of the compromises were following a different pattern than we'd been seeing over the past couple of weeks. Further investigation revealed the newest iframe injection was pointing once again to gumblar .cn - the malware domain that originally earned Gumblar its name. The domain's reactivation occurred less than 24 hours ago, but it has ramifications that could stretch back for months. Any sites compromised in the May Gumblar attacks that were not yet cleaned up (unfortunately an all-to-common occurrence) could now start becoming vectors of Gumblar infection once again. This is in addition to new compromises pointing to the newly activated gumblar .cn and the already very active Gumblar compromises which are using compromised websites as malware hosts*...
    Edited to add: This is not the first example of registrars releasing malware domain names back into use..."

    Thumbs down The Gumblar system

    FYI...

    The Gumblar system
    - http://www.viruslist.com/en/weblog?weblogid=208187897
    November 11, 2009 - "... Analysis of some infected websites showed that the only way to inject the infection of Gumblar was by using FTP access, because those websites have no server-side scripting. Later this was proved by an analysis of FTP log files... it's a fully automated system. It's a new generation of self-building botnets. This system is actively attacking visitors of a website and once these visitors have been infected with the Windows executable, it grabs FTP credentials from the victim machines. The FTP accounts are then used to infect every webpage on new webservers. This way the system extends the number of infected pages, thus attacking more and more computers. The entire process is automated and the owner of the system just needs to adjust the system and update the Trojan executable which steals passwords and the exploits used to attack the browser. The system works in a constant loop of attacking new computers, getting new FTP accounts and infecting new servers..."

    December 04, 2009 - "We've now analyzed more than 600 MB of collected data related to the recent resurrection of the Gumblar threat. Overall, we've identified 2000+ Infectors (computers hosting the malicious *.php files and payload) and 76100+ 'Redirectors' (computers with links leading back to the malicious sites). Most Infectors are also part of the group of Redirectors, they serve one *.php file and additionally contain the link to another Infector in their own entry page..."

    Thumbs down Max Power - many malware domains

    FYI...

    Max Power - many malware domains
    - http://isc.sans.org/diary.html?storyid=7693
    Last Updated: 2009-12-04 19:46:31 UTC - "Who Max Power is? Well, we don't know either. It's a pseudonym of a gang or guy who has a decent-sized spyware racket going. Max has been sitting on the same IP address for the past three months, 210.51.166.119, in AS9929. ChinaNet. Even Google knows that 10% of the sites in this AS are malicious. Looking at the IP address in Reverse DNS or MalwareURL.com, we can see the many malware domains "Max Power" has been using in the recent past. Some of the names are associated with the Koobface and Zeus malware families. The address lay dormant for the last week of November, but just woke up again yesterday morning, and is currently serving the malware domain "tempa3-dot-cn". This domain is at the moment linked to from various questionable "pharmaceuticals" web sites, and it currently pushes a bunch of exploits which, if successful, download and run a backdoor of the "TDSS"/"Tidserv" family. Detection was dismal at first*, but has improved a bit over the last 24 hours**."

    Thumbs down Zeus bot using Amazon as C&C server

    Zeus bot using Amazon as C&C server
    - http://www.theregister.co.uk/2009/12...ntrol_channel/
    9 December 2009 - "... a new variant of the Zeus banking trojan has been spotted using the popular Amazon service as a command and control channel for infected machines. After marks get tricked into installing the password-logging malware, their machines began reporting to EC2 for new instructions and updates, according to researchers from CA's internet security business unit*... Over the past few months, accounts on Twitter, Google's app engine, and Facebook have also been transformed into master control channels for machines under the spell of surreptitious malware... According to analysis** from Zero Day blogger Dancho Danchev, the cybercriminals behind Zeus appear to have plugged into Amazon's Relational Database Service as a backend alternative in case they lose access to their original domain..."

    Thumbs down Conficker worm hotbeds...

    FYI...

    Group IDs hotbeds of Conficker worm outbreaks
    - http://voices.washingtonpost.com/sec...conficker.html
    December 16, 2009 - "Internet service providers in Russia and Ukraine are home to some of the highest concentrations of customers whose machines are infected with the Conficker worm, new data suggests. The report comes from the Shadowserver Foundation*, a nonprofit that tracks global botnet infections. Shadowserver tracks networks and nations most impacted by Conficker, a computer worm that has infected more than 7 million Microsoft Windows PCs since it first surfaced last November... Shadowserver's numbers indicate that the largest numbers of Conficker-infested PCs are in the East, more specifically China, India and Vietnam. For example, Chinanet, among the nation's largest ISPs, has about 92 million routable Internet addresses, and roughly 950,000 - or about 1 percent of those addresses - appear to be sickened with Conficker. Security Fix decided to use the group's data in a slightly different way, to showcase the concentration of Conficker victims as viewed against the total number of each ISP's customers. Viewed this way, Russian and Ukrainian ISPs have the highest concentration of customers with Conficker-infected systems... Shadowserver offers all ISPs and Web hosting providers free daily feeds** that can alert network providers to new bot infections on their networks."

    Thumbs down iPhone Botnet...

    FYI...

    Analysis of the iKee.B (Duh) iPhone Botnet
    - http://www.csl.sri.com/users/porras/iPhone-Bot/
    14 December 2009 - "... analysis of the iKee.B (duh) Apple iPhone bot client, captured on 25 November 2009. The bot client was released throughout several countries in Europe, with the initial purpose of stealing SMS content and coordinating its infected iPhones via a Lithuanian botnet server. This report details the logic and function of iKee's scripts, its configuration files, and its two binary executables, which we have reverse engineered to an approximation of their C source code implementation. The iKee bot is one of the latest offerings in smartphone malware, in this case targeting jailbroken iPhones. While its implementation is simple in comparison to the latest generation of PC-based malware, its implications demonstrate the potential extension of crimeware to this valuable new frontier of handheld consumer devices...
    In early November 2009, Dutch users of jailbroken iPhones in T-Mobile's 3G IP range began experiencing extortion popup windows. The popup window notifies the victim that the phone has been hacked, and then sends that victim to a website where a $5 ransom payment is demanded to remove the malware infection. The teenage hacker who authored the malicious software (malware) had discovered that many jailbroken iPhones have been configured with a secure shell (SSH) network service with a known default root password..."

    Thumbs down Citibank hacked for millions...

    FYI...

    Citibank hacked for millions...
    - http://www.pcworld.com/businesscente...bank_hack.html
    December 21, 2009 - "U.S. authorities are investigating the theft of an estimated tens of millions of dollars from Citibank by hackers partly using Russian software tailored for the attack, according to a news report. The security breach at the major U.S. bank was detected mid-year based on traffic from Internet addresses formerly used by the Russian Business Network gang, The Wall Street Journal said Tuesday*, citing unnamed government sources. The Russian Business Network is a well-known group linked to malicious software, hacking, child pornography and spam. The Federal Bureau of Investigation is probing the case, the report said. It was not known whether the money had been recovered and a Citibank representative said the company had not had any system breach or losses, according to the report. The report left unclear who the money was stolen from but said a program called Black Energy, designed by a Russian hacker, was one tool used in the attack. The tool can be used to command a botnet, or a large group of computers infected by malware and controlled by an attacker, in assaults meant to take down target Web sites. This year a modified version of the software appeared online that could steal banking information, and in the Citi attack a version tailored to target the bank was used, the Journal said. The attackers also targeted a U.S. government agency and one other unnamed entity, the report said, adding that it was unknown if the attackers accessed Citibank systems directly or through other parties."

    December 22, 2009 - "... Citigroup denied the report. "We had no breach of the system and there were no losses, no customer losses, no bank losses," said Joe Petro, managing director of Citigroup's Security and Investigative services. "Any allegation that the FBI is working a case at Citigroup involving tens of millions of losses is just not true"..."
