Last week we spoke about the Boonana cross-platform malware, using a malicious Java applet to deliver a cross-platform attack that attempts to download further malware to computers running Windows, Unix and Mac OS X.
Since then some we have seen variants of the original Boonana attack. The samples we have seen have been functionally the same, with the hackers behind them seemingly having obfuscated their code to try and waltz around detection.
Their attempts haven’t been good enough to get past Sophos’s products so far (including our new free anti-virus for Mac home users), and we haven’t had to update our generic detection method.
In the samples we have analysed to date, the attack specifically targets Windows and Mac OS X systems, and just happens to infect other platforms that run Java. Depending upon the flavour of Unix, it doesn’t usually complete its ‘life cycle’ if you’re not running Windows or Mac OS X systems.
Of course, we will update our detection of Troj/Boonana should we see new variants that require it.
In the meantime, watch this video I made last week demonstrating the original version of this attack on Windows, Mac OS X and Ubuntu:
Adobe has issued a security bulletin detailing critical vulnerabilities that have been discovered in the current versions of Adobe Flash Player for Windows, Macintosh, Solaris and Linux.
An update issued by Adobe claims to resolve 32 vulnerabilities in Flash Player – which if left unpatched could leave open a door for hackers to infect innocent users’ computers. Some of the security holes are already being exploited by malicious hackers.
Adobe is recommending that users upgrade to Adobe Flash Player 10.1.53.64.
If you’re not sure which version of the Adobe Flash Player you have installed, visit theAbout Flash Player page. Remember that if you use more than one browser on your computer you should check the version number on each.
Adobe further recommends that users of Adobe AIR version 188.8.131.5230 and earlier versions update to Adobe AIR 2.02.12610.
It is becoming more and more common for cybercriminals to exploit vulnerabilities in Adobe’s software – so it would be a very good idea for everyone to update vulnerable computers as soon as possible.
TrID is an utility designed to identify file types from their binary signatures. While there are similar utilities with hard coded rules, TriID has no such rules. Instead, it is extensible and can be trained to recognize new formats in a fast and automatic way.
