The July issue of Virus Bulletin is now available for subscribers to download.

The July 2011 issue of Virus Bulletin is now available for subscribers to browse online or download in PDF or PRC (Kindle) format.

Some of the things this month's issue has in store are:

• Tumblr attacks - what to watch out for: 'Tumblr is definitely a hot property for scammers, and users should be very careful' warns Christopher Boyd, GFI Software.

• Toll fraud: SipPhreak: PHP/SipPhreak.A acts like an ancient SMTP open relay scanner, but with a twist: it targets open or vulnerable SIP devices instead of mail servers. Alexis Dorais-Joncas gives a detailed analysis of this threat - which is probably the initial step in a broader toll fraud scheme.

• SpyEye malware infection framework: The SpyEye bot has a sophisticated, modular design and has improved its capabilities over time. Aditya Sood and colleagues examine SpyEye's modules and map out how they are initialized and how they interact with each other, providing an insight into the design and methods of the bot, and into an effective instance of modern malware.

• Reversing Python objects: As Python has gained popularity with malware writers, new bytecode obfuscation techniques have started to appear. Aleksander Czarnowski describes some of those techniques.

• Not so random: Pseudorandom generators are increasingly becoming an integral component of modern malware. Raul Alvarez shows how Conficker uses a pseudorandom generator to produce random domain names while retaining its ability to communicate with the Command and Control server.

Note: The July 2011 VBSpam comparative review will be published as standalone article in mid-July. As with all new VB100 and VBSpam reviews, the report will be available for non-subscribers to purchase as a standalone item (Virus Bulletin subscribers will be notified by email when the comparative is available to download). Non-subscribers can purchase VB100 reports here and VBSpam reports here.
