Ransomware getting harder to break

Shield Ransomware getting harder to break

Hackers may soon be pushing out ransomware packages so complex that they're beyond the decryption capabilities of the anti-virus industry, according to a study by Russian anti-virus firm Kaspersky Lab.

The report, Malware Evolution: April – June 2006, Hidden Wars, states that the creators of so-called ransomware packages are making the lives of security researchers more difficult by using more powerful and sophisticated encryption algorithms. Ransomware packages use malicious code to gain control of user files, encrypt them and threaten users that they won't see these files again unless they hand over a cash "ransom" to hackers.

Examples of ransomware malware, which made its first appearance only months ago, include Gpcode, Cryzip, and Krotten. At first the encryption approaches taken by hackers were crude. But Gpcode-AC, first detected in January 2006, used the RSA algorithm to create a 56-bit key. Since then, the unknown author of the virus has produced variants that use more complex encryption keys. The last detected variant Gpcode-AG uses a 660-bit key.
