Ransomware style trojans will be tougher to break in their next iteration, according to leading AV firms.

The existing trojans, which encrypt your files and demand a fee for the access key, are fairly simple symmetric cipher affairs. AV vendor Kaspersky predict that the key length will increase - making brute-force attacks impossible, and more sophisticated public key crypto could appear.

Relying on the "good guys" to break the encryption is probably a pretty bad idea - keeping viruses and trojans off your systems and hedging your bets with backups is a wise policy.
