Security firms are warning about a sudden “huge” surge in junk mail messages containing ransomware.
The surge is being blamed on the group behind a novel strain of ransomware called Locky.
One security firm reported that a version of Locky produced two weeks ago is now the second most prevalent form of ransomware it sees.
We are urging our customers to be extremely careful when opening any attachments in your email. If in doubt don’t open it.
Ransomware is a type of malware that restricts access to the infected computer system in some way, and demands that the user pay a ransom to the malware operators to remove the restriction. Some forms of ransomware systematically encrypt files on the system’s hard drive, which become difficult or impossible to decrypt without paying the ransom for the encryption key, while some may simply lock the system and display messages intended to coax the user into paying. Ransomware typically propagates as a Trojan, whose payload is disguised as a seemingly legitimate file.
If you are infected please call us immediately as the threat is usually on a timer.
Please also ensure that you have a current backup of all your files.
