VISA and MasterCard are alerting banks across the country about a recent major breach at a U.S.-based credit card processor. Sources in the financial sector are calling the breach “massive,” and say it may involve more than 10 million compromised card numbers.
Adobe has issued a security update for its Flash Player software that fixes at least two critical vulnerabilities in the widely-used browser plugin. At long last, this latest version also includes an auto-updating mechanism designed to streamline the deployment of Flash security fixes across multiple browsers.
If it seems like you just updated Flash to fix security holes, it’s not your imagination. This is the third security update for Flash in the last six weeks. Flash Player v. 11.2 addresses a couple of flaws in Adobe Flash Player 188.8.131.52 and earlier versions for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 184.108.40.206 and earlier versions for Android 3.x and 2.x. Adobe warns that these vulnerabilities could cause a crash and potentially allow an attacker to take control of the affected system.
Experts from across the security industry collaborated this week to quarantine more than 110,000 Microsoft Windows PCs that were infected with the Khelios worm, a contagion that forces infected PCs to blast out junk email advertising rogue Internet pharmacies.
Most botnets are relatively fragile: If security experts or law enforcement agencies seize the Internet servers used to control the zombie network, the crime machine eventually implodes. But Khelios (a.k.a. “Kelihos”) was built to withstand such attacks, employing a peer-to-peer structure not unlike that used by popular music and file-sharing sites to avoid takedown by the music and entertainment industry.
If your computer is running Java and you have not updated to the latest version, you may be asking for trouble: A powerful exploit that takes advantage of a newly-disclosed security hole in Java has been rolled into automated exploit kits and is rapidly increasing the success rates of these tools in attacking vulnerable Internet users.
Microsoft today announced the execution of a carefully planned takedown of dozens of botnets powered by ZeuS and SpyEye — powerful banking Trojans that have helped thieves steal more than $100 million from small to mid-sized businesses in the United… Read More »
Last week was a bad one to be a cybercrook. Authorities in Russia arrested several men thought to be behind the Carberp banking Trojan, and obtained a verdict of guilty against the infamous spammer Leo Kuvayev. In the United States, a jury returned a 33-month jail sentence against a Belarusian who ran a call service for cyber thieves. At the same time, U.S. prosecutors secured a guilty plea against a Russian man who was part of a gang that stole more than $3 million from U.S. businesses fleeced with the help of the ZeuS Trojan.
Employee and financial records leaked from some of the world’s largest sponsors of spam provide new clues about the identity of a previously unknown Russian man believed to have been closely tied to the development and maintenance of “Bredolab,” a massive collection of hacked machines that was disassembled in an international law enforcement sweep in late 2010.
In October 2010, Armenian authorities arrested 27-year-old Georg Avanesov on suspicion of running Bredolab, a botnet that infected an estimated 3 million PCs per month through virus-laden e-mails and booby-trapped Web sites. The arrest resulted from a joint investigation between Armenian police and cyber sleuths in the Netherlands, whose ISPs were home to at least 143 servers used to direct the botnet’s activities.
Twitter bots — automated accounts that auto-follow and send junk tweets hawking questionable wares and services — can be an annoyance to anyone who has even a modest number of followers. But increasingly, Twitter bots are being used as a tool to suppress political dissent, as evidenced by an ongoing flood of meaningless tweets directed at hashtags popular for tracking Tibetan protesters who are taking a stand against Chinese rule.
It’s not clear how long ago the bogus tweet campaigns began, but Tibetan sympathizers say they recently noticed that several Twitter hashtags related to the conflict — including #tibet and #freetibet — are now so constantly inundated with junk tweets from apparently automated Twitter accounts that the hashtags have ceased to become a useful way to track the conflict.

A Web site that bills itself as a place where independent and open source software developers can hire each other has secured promises to award at least $1,435 to the first person who can develop a working exploit that takes advantage of newly disclosed and dangerous security hole in all supported versions of Microsoft Windows.
That reward, which is sure to only increase with each passing day, is offered to any developer who can devise an exploit for one of two critical vulnerabilities that Microsoft patched on Tuesday in its Remote Desktop Protocol (RDP), designed as a way to let administrators control and configure machines remotely over a network.
