Over the last week we have seen an increase in the amount of companies receiving emails containing Zepto Ransomware, a file encrypting virus based on the infamous Locky cryptoware.
Most of the emails have been carefully crafted to ensnare the victims using social engineering techniques, typically greeting the recipient by first name and asking them to open an attachment which they had requested.

The attachment will typically be either a .zip extension or .docm extension and once opened will run a malicious JavaScript which then encrypts all files on the users machine with the .zepto extension

To try and combat the infection, we offer the following advice
1. To protect against JavaScript attachments, tell Explorer to open .JS files with Notepad.
2. To protect against VBA malware, tell Office not to allow macros in documents from the internet.
3. Ensure your AntiMalware program is upto date
4. Ensure your users are careful with email attachments and only open the ones they are sure they have requested
5. If possible set email filtering to quarantine all .zip and .docm files
