Zenis Ransomware Encrypts Your Data & Deletes Your Backups
(Mar 16, 2018)
The security researcher known as "MalwareHunterTeam" has discovered a new ransomware family dubbed "Zenis." At the time of this writing, it is unknown how the threat actor(s) behind are distributing the ransomware, however, it may be possible that it is being delivered via compromised Remote Desktop services. Zenis, which has been observed to have infected multiple victims already, is not only capable of encrypting files with a custom encryption method but will also delete backups.
Recommendation: Always run antivirus and endpoint protection software to assist in preventing ransomware infection. Maintain secure backups of all your important files to avoid the need to consider payment for the decryption key, and implement a business continuity plan in the unfortunate case of ransomware infection. Emails received from unknown sources should be carefully avoided, and attachments and links should not be followed or opened. Your company should sustain policies to consistently check for new system security patches. In the case of ransomware infection, the affected systems should be wiped and reformatted, even if the ransom is paid. Other machines on the same network should be scanned for other potential infections.
