Ransomware Targeting UK SME’s

Cryptolocker

An online attack that can inject ransomware into potentially millions of UK businesses is being investigated by the National Cyber Crime Unit.

The attack has been discovered taking the form of an email which has taken the fake identity of financial companies in the UK. The spammer sends emails to small and medium sized businesses with a malicious attachment, which if opened releases ransonware into the targeted system.

The malicious program used is called Cryptolocker and targets devices running Windows operating systems. Cryptolocker encrypts files and demands a value of over £500 to decrypt them. Whether or not the cyber criminals sending these emails will honour the ransom is another question.

It’s advised that no payments are made to meet any ransoms and in the first instance that no unknown or suspicious looking attachments are opened.
