Malwarebytes researchers recently found that the cybercriminals behind the CryptoLocker ransomware are now offering a late payment option of sorts, for a payment of about $2,200.

Previously, if the $300 ransom wasn't paid within three days, the private key required to retrieve the victim's files was simply deleted.

A new "CryptoLocker Decryption Service" offers access to encrypted files after the three-day period for a ransom payment of 10 Bitcoins, or approximately $2,200.

"This new development is certainly alarming and shows the bad guys are confident that despite the price increase, some people will in fact pay," writes Malwarebytes senior security researcher Jerome Segura.

Segura notes that CryptoLocker is much easier to block than to repair, and advises users to exercise caution when opening e-mail attachments, keep their PCs updated, be sure to have anti-virus and anti-malware protection installed, and back up important data on a regular basis.
