Microsoft Patches Zero-Day Bug & 15 Other Flaws

Microsoft today issued a security patch to fix a zero-day vulnerability in Windows that hackers have been exploiting to break into vulnerable systems. The company also addressed at least 15 other flaws in its software, and urged customers to quit using the desktop Sidebar and Gadget capabilities offered in Windows 7 and Windows Vista.

By far the most urgent of the updates is MS12-043, which fixes a critical vulnerability in Microsoft XML Core Services that miscreants and malware alike have been using to break into vulnerable systems. Microsoft had already warned about limited, targeted attacks using this flaw, but late last month an exploit built to attack the XML bug was added to the BlackHole Exploit Kit, an automated browser exploit tool that is very popular in the criminal underground right now.

Other critical patch bundles include a fix for a dangerous flaw in the Microsoft Data Access Components (MDAC) of Windows, and an update to address a pair of vulnerabilities in Internet Explorer. Continue reading →

‘Weyland-Yutani’ Crime Kit Targets Macs for Bots

A new crimeware kit for sale on the criminal underground makes it a simple point-and-click exercise to develop malicious software designed to turn Mac OSX computers into remotely controllable zombie bots. According to the vendor of this kit, it is somewhat interchangeable with existing crimeware kits made to attack Windows-based PCs.

The Mac malware builder in action.

KrebsOnSecurity has spilled a great deal of digital ink covering the damage wrought by ZeuS and SpyEye, probably the most popular crimeware kits built for Windows. A crimeware kit is a do-it-yourself package of tools that allow users to create custom versions of a malicious software strain capable of turning machines into bots that can be remotely controlled and harvested of financial and personal data. The bot code, generated by the crimeware kit’s “builder” component, typically is distributed via social engineering attacks in email and social networking sites, or is foisted by an exploit pack like Eleonore or Blackhole, which use hacked Web sites and browser flaws to quietly install the malware. Crimeware kits also come with a Web-based administration panel that allows the customer to manage and harvest data from infected PCs.

Crimekit makers have focused almost exclusively on the Windows platform, but today Danish IT security firm CSIS Security Group blogged about a new kit named the Weyland-Yutani BOT that is being marketed as the first of its kind to attack the Mac OS X platform.

The seller of this crimeware kit claims his product supports form-grabbing in Firefox and Chrome, and says he plans to develop a Linux version and one for the iPad in the months ahead. The price? $1,000, with payment accepted only through virtual currencies Liberty Reserve or WebMoney.

The CSIS blog post contains a single screen shot of this kit’s bot builder, and references a demo video but doesn’t show it. I wanted to learn more about this kit, and so contacted the seller via a Russian language forum where he was advertising his wares.

The author said he is holding off on including Safari form-grabbing capability for now, complaining that there are “too many problems in that browser.” Still, he was kind enough to share a copy of a video that shows the kit’s builder and admin panel in action. Click the video link below to check that out.

ZeuS and SpyEye are popular in part because they support a variety of so-called “Web injects,” third-party plug-ins that let botmasters manipulate the content that victims see in their Web browsers. The most popular Web injects are designed to slightly alter the composition of various online banking Web sites in a bid to trick the victim customer into supplying additional identifying information that can be used later on to more fully compromise or hijack the account. According to the author, Web injects developed for ZeuS and SpyEye also are interchangeable with this Mac crimekit. “They need to be formatted and tagged, but yes, you can use Zeus injects with this bot,” he told me in an instant message conversation.
