wiredmikey writes "Microsoft, in what it called its 'most complex effort to disrupt botnets to date,' and in collaboration with partners from the financial services industry, has successfully taken down operations that fuel a number of botnets that make up the notorious Zeus family of malware. In what Microsoft is calling 'Operation b71,' Microsoft and its co-plaintiffs, escorted by U.S. Marshals, seized command and control (C&C) servers in two hosting locations on March 23 in Scranton, Pennsylvania and Lombard, Illinois. The move was to seize and preserve data and evidence from the botnets for the case. In addition to seizing the C&C servers, the group took down two IP addresses behind the Zeus command and control structure, and secured 800 domains that Microsoft is now monitoring and using to help identify computers infected by Zeus."

Trailrunner7 writes "The U.S.'s leading Internet Service Providers signed on to a new FCC code of conduct to limit the impact of major cyber security threats, including botnets, attacks on the Domain Name System and Internet routing attacks. AT&T, CenturyLink, Comcast, Cox, Sprint, Time Warner Cable, T-Mobile and Verizon were among the ISPs that participated in the agreement. 'The recommendations approved today identify smart, practical, voluntary solutions that will materially improve the cyber security of commercial networks and bolster the broader endeavors of our federal partners,' said FCC Chairman Julius Genachowski." A fact sheet from the FCC provides details on the recommendations, but they're pretty vague: "The CSRIC recommended ISPs participate in a U.S. Anti-Bot Code of Conduct (PDF) that encourages ISPs to engage in: (1) end-user education to prevent bot infections; (2) detection of bots; (3) notification of potential bot infections; (4) remediation of bots; and (5) collaboration and sharing of information." They also recommend broader adoption of DNSSEC and the development of an "industry framework" to combat IP route hijacking.

dsinc sends this quote from a Symantec report: "In 2011, dozens of Anonymous members who participated in distributed denial-of-service (DDoS) attacks in support of Anonymous hacktivism causes were arrested. In these DDoS attacks, supporters using the Low Orbit Ion Cannon denial-of-service (DoS) tool would voluntarily include their computer in a botnet for attacks in support of Anonymous. In the wake Anonymous member arrests this week, it is worth highlighting how Anonymous supporters have been deceived into installing Zeus botnet clients purportedly for the purpose of DoS attacks. The Zeus client does perform DoS attacks, but it doesn’t stop there. It also steals the users' online banking credentials, webmail credentials, and cookies. The deception of Anonymous supporters began on January 20, 2012, the day of the FBI Megaupload raid."

c0mpliant writes "Researchers at Symantec have identified a new variant of the ZeuS botnet which no longer requires a Command and Control server. The new variant uses a P2P system, which means that each bot acts like a C&C server, but none of them really are. The effect of which is that takedowns of such a network will be extremely difficult because there is no one central source to attack."

alphadogg writes "U.S. Internet service providers should take new steps to protect subscribers against cyber attacks, including notifying customers when their computers are compromised, the chairman of the FCC said Wednesday. Julius Genachowski called on ISPs to notify subscribers whose computers are infected with malware and tied to a botnet and to develop a code of conduct to combat botnets. Genachowski also called on ISPs to adopt secure routing standards to protect against Internet Protocol hijacking and to implement DNSSEC, a suite of security tools for the Internet's Domain Name System."

tsu doh nimh writes "Millions of computers infected with the stealthy and tenacious DNSChanger Trojan may be spared a planned disconnection from the Internet early next month if a New York court approves a new request by the U.S. government. Meanwhile, six men accused of managing and profiting from the huge collection of hacked PCs are expected to soon be extradited from their native Estonia to face charges in the United States."

An anonymous reader writes "Details of the tools, techniques and procedures used by the hackers behind the RSA security breach have been revealed in a research paper (PDF) published by Australian IT security company Command Five. The paper also, for the first time, explains links between the RSA hack and other major targeted attacks. This paper is a vendor-neutral must-read for any network defenders concerned by the hype surrounding 'Advanced Persistent Threats.'"

tsu doh nimh writes "Two months after authorities shut down a massive Internet traffic hijacking scheme, the malicious software that powered the criminal network is still running on computers at half of the Fortune 500 companies, and on PCs at nearly 50 percent of all federal government agencies. Internet Identity, a Tacoma, Wash. company that sells security services, found evidence of at least one DNSChanger infection in computers at half of all Fortune 500 firms, and 27 out of 55 major government entities. Computers still infected with DNSChanger are up against a countdown clock. As part of the DNSChanger botnet takedown, the feds secured a court order to replace the Trojan's DNS infrastructure with surrogate, legitimate DNS servers. But those servers are only allowed to operate until March 8, 2012. Unless the court extends that order, any computers still infected with DNSChanger may no longer be able to browse the Web. The FBI is currently debating whether to extend the deadline or let it expire."

angry tapir writes "A botnet that was crippled by Microsoft and Kaspersky Lab last September is spamming once again and experts have no recourse to stop it. The Kelihos botnet only infected 45,000 or so computers but managed to send out nearly 4 billion spam messages a day, promoting, among other things, pornography, illegal pharmaceuticals and stock scams. But it was temporarily corralled last September after researchers used various technical means to get the 45,000 or so infected computers to communicate with a "sinkhole," or a computer they controlled."

tsu doh nimh writes "A Wikileaks-style war of attrition between two competing rogue Internet pharmacy gangs has exposed some of the biggest spammers on the planet. Brian Krebs uncovers fascinating information about a hacker named 'GeRa' who is supposedly behind the Grum botnet, which is currently sending about one out of every three spam emails worldwide. The story also points to several possible real-identities behind the Internet's largest spam machine."

wiredmikey writes with an update on Microsoft's takedown of the Kelihos botnet. From the article: "Microsoft is not just taking down botnets; it is taking them down and naming names. In an amended complaint [PDF] filed Monday in U.S. District Court for the Eastern District of Virginia, Microsoft named a man from St. Petersburg, Russia, as the alleged head of the notorious Kelihos botnet. Naming names can be a risky business. Previously, Microsoft alleged Dominique Alexander Piatti, dotFREE Group SRO and several unnamed 'John Does' owned a domain cz.cc and used cz.cc to register other subdomains used to operate and control the Kelihos botnet. However, the company later absolved Piatti of responsibility when investigators found neither he nor his business was controlling the subdomains used to host Kelihos. Whether naming Sabelnikov – who, according to Krebs on Security, once worked as a senior system developer and project manager for Russian antivirus vendor Agnitum, will have the same effect as naming the Koobface gang remains to be seen. Though Kelihos has remained defunct since the takedown last year, the malware is still on thousands of computers."

New submitter theonlyholle writes "Naked Security, the Sophos IT security blog, has published an article about the authors of the Koobface malware that plagued Facebook users in 2008 and the investigation that led to their identification. Apparently the botnet was created by five Russians from St. Petersburg."

chicksdaddy wrote in with a link to a story about a Microsoft project that will share security information in real time with customers and law enforcement. The article reads "Microsoft has proven that it can take down huge, global botnets like Kelihos, Rustock and Waldec. Now the company is ready to start making the data it acquires in those busts available to governments, law enforcement and customers as a real time threat intelligence feed. Representatives from the Redmond, Washington software maker told an audience at the International Conference on Cyber Security (ICCS) here that it was testing a new service to distribute threat data from captured botnets and other sources to partners, including foreign governments, Computer Emergency Response Teams (CERTs) and private corporations."

An anonymous reader writes "New analysis of financial records and online chat logs retrieved from the operators of Spamdot.biz — until recently the most notorious spam affiliate program — provides tantalizing clues about the identity of the man behind Cutwail, currently the largest spam botnet. Brian Krebs tells the story of 'Google,' the screen name used by the now-27-year-old botmaster who was part of a team of programmers in Moscow. Over the years, Cutwail has shifted from a spam cannon for male enhancement pills to a major vector for distributing malicious software."

itwbennett writes "In a presentation at the Usenix LISA conference in Boston, researchers from the Naval Academy showed that signal analysis of factors such as timing, packet reordering, congestion and flow control can reveal the work of a spam-spewing botnet. The work 'advanced both the science of spam fighting and ... worked through all the engineering challenges of getting these techniques built into the most popular open-source spam filter,' said MIT computer science research affiliate Steve Bauer, who was not involved with the work. 'So this is both a clever bit of research and genuinely practical contribution to the persistent problem of fighting spam.'"

tsu doh nimh writes "It appears that thousands of Twitter accounts created in advance to blast automated messages are being used to drown out Tweets sent by bloggers and activists this week who are protesting the disputed presidential elections in Russia. Trend Micro first observed on Wednesday the bogus tweets flooding popular hashtags being used by Russians protesting the election and the arrests of hundreds of protesters, including prominent anti-corruption blogger Alexei Navalny. Today, blogger Brian Krebs posted evidence that thousands of accounts apparently auto-created in mid-2011 were being used to flood more than a dozen hashtags connected to the protests, and appear to be all following each other and one master account, presumably the botnet controller."

wiredmikey writes "A compromised server at the Massachusetts Institute of Technology (MIT) has been identified as being used as a vulnerability scanner and attack tool, probing the Web for unprotected domains and injecting code. According to researchers, the ongoing attacks appear to be related to the Blackhole Exploit Pack, a popular crime kit used by criminals online. The attacks started in June, and an estimated 100,000 domains could have been compromised. Judging by initial data, one MIT server (CSH-2.MIT.EDU) hosts a malicious script actively used by cyber-crooks to scan the web for vulnerable websites. These types of attacks are how BlackHat SEO scams are propagated, which target search results in order to spread rogue anti-virus or other malware. In addition, compromised hosts are also leveraged for other schemes, such as spam or botnet control."

wiredmikey writes "Microsoft has dismissed a lawsuit against a company it contended a month ago was at the heart of the now-defunct Kelihos botnet. In September, Microsoft named Dominique Piatti and his company dotFree Group SRO as controllers of the botnet. The move marked the first time Microsoft had named a defendant in one of its botnet-related civil suits. 'Since the Kelihos takedown, we have been in talks with Mr. Piatti and dotFree Group s.r.o. and, after reviewing the evidence voluntarily provided by Mr. Piatti, we believe that neither he nor his business were involved in controlling the subdomains used to host the Kelihos botnet,' blogged Richard Domingues Boscovich, Senior Attorney for Microsoft's Digital Crimes Unit. 'Rather, the controllers of the Kelihos botnet leveraged the subdomain services offered by Mr. Piatti's cz.cc domain.' In regards to Kelihos, Boscovich said Microsoft is continuing its legal fight against the 22 'John Does' listed as co-defendants in the lawsuit."

Trailrunner7 writes "There is a new worm circulating right now that is compromising servers running older versions of the JBoss Application Server and then adding them to a botnet. The worm also attempts to install a remote access tool in order to give the attacker control over the newly infected server. The worm has been circulating for a couple of days at least, and it's not clear right now how many servers have been compromised or what the origins of it are. It apparently exploits an old vulnerability in the JBoss Application Server, which was patched in April 2010, in order to compromise new machines. Once that's accomplished, the worm begins a post-infection routine that includes a number of different steps."

jfruhlinger writes "TDL4, a rootkit that helps build a powerful botnet, is pegged by security vendor ESET as one of the most sophisticated pieces of malware in the world. But its creators aren't resting on their laurels; they're rewriting some of the code from the ground up to make it difficult for antimalware to detect it, creating a hidden boot partition that guarantees malware code will be loaded even before the operating system is. It's part of a plan to turn TDL4 into a turnkey product that can be sold to other criminal operations."
