The last couple of weeks has seen an increase in a new variant of the Ransomware type attacks. Ransomware is a program that loads on to your PC and then encrypts everything, demanding a ransom to be paid to unlock the files. The virus is normally introduced through inadvertently clicking on the attachment of an infected email. They can also come through visiting compromised web sites, although this is less common.
This particular one is different as it gets access to any network share, whether it’s mapped to a drive letter or not. This is a worrying development as so far they have only been able to encrypt network resources if there was a drive letter mapped to a network share. Because of this new development, this virus can easily destroy all the files on your servers.
Most of you have your email filtered through Messagelabs but even so, can you please remind everyone not to click on any attachment where they are not 100% percent sure of the sender and its contents.
Also we still have the ‘phishing’ emails floating about. These can spoof the email address of directors in your organisation asking you to transfer money. These are very difficult to stop as there is no malicious payload to the email to help identify it, so please be on guard against any emails asking you to transfer money.
