Virus Alert: Virus.Win32.Gpcode.ak cripta i file del disco rigido.

Virus.Win32.Gpcode.ak, il virus che cripta tutti i file del disco rigido e... chiede il riscatto per decriptarli. Kaspersky Lab ha identificato la nuova variante del virus ma il lavoro per il decrypt dei file ed il craking della chiave si presenta molto difficile: il virus implementa un'algoritmo di cifratura RSA con chiave a 1024-bit.
Kaspersky chiede aiuto a tutti: "... So we're calling on you: crytographers, governmental and scientific institutions, antivirus companies, independent researchers…join with us to stop Gpcode. This is a unique project – uniting brain-power and resources out of ethical, rather than theoretical or malicious considerations..."


"... Kaspersky Lab has detected a new version of the ‘malicious blackmailer’ Gpcode - Virus.Win32.Gpcode.ak.
The new Gpcode variant encrypts files with extensions DOC, TXT, PDF, XLS, JPG, PNG, CPP, H etc. on hard drives using an RSA algorithm with a 1024-bit key..."
"... However, although we detect the virus itself, we can't currently decrypt files encrypted by Gpcode.ak – the RSA encryption implemented in the malware uses a very strong, 1024 bit key..."
