Along with antivirus companies around the world, we’re faced with the task of cracking the RSA 1024-bit key. This is a huge cryptographic challenge.

Following on from Vitaly’s post about the new Gpcode variant, I just thought I’d remind everyone to back up their data.

Yesterday I received a sample which seemed quite interesting. Turns out that the specimen was a bank Trojan which specifically targets (among others) a Dutch bank.

Over the last couple of days there’s been quite a lot of talk about a Trojan + rootkit called Hearse. We detect this malware as Trojan-Spy.Win32.Goldun.im.

Kaspersky Lab analysts have traced the source of Krotten (see yesterday’s blog by Yury Mashevsky for more information).

The program was spreading disguised as a program which would generate codes to top up mobile phones. It was placed on a site located in Russia which was hosted free of charge….

We’re starting to see a growth in the number of malicious programs which are being used to get money out of users – a type of cyber extortion.
