The BBC have reported warnings of a “huge surge in messages containing ransomware” this week, sparking security firms to speak out on a new kind of Ransomware, ‘Locky’.
As in our CryptoWall post, we recommend avoiding the following to help steer clear of infection:
- Any emails with attachments which looks like an invoice, complaint or purchase order or from an address you don’t recognise. Always verify with the sender that this is a genuine email before you decide to open the attachment.
- Any emails with .ZIP attachments. This is how the Cryptowall attachments are usually displayed. Check it with the sender to verify it.
- Any emails with .exe attachments. These will almost definitely be a virus – never open. Usually they will hide a .exe file within a zip file. You can check the file extension to make sure.
- Using personal email accounts – If using web-based email accounts like gmail, hotmail, Yahoo!, etc. – any email needs to be checked meticulously as these will not have the same level of protection as company email accounts. If you need to check your personal emails, we would recommend using your mobile phone.
Other ways to protect your data
You can’t always rely on your staff following our guidelines to the letter. If you could, cybercriminals wouldn’t bother with Ransomware.
So what else can you do to protect your data?
