We all know and fear ransomware attacks, and with good reason. In 2017 the average cost per ransomware attack to businesses was $133,000, a company was hit with ransomware every 40 seconds and 1 in 5 businesses that paid the ransom never got their files back.
So we welcomed Bitdefender Labs last week when they released a free tool to help GandCrab ransomware victims get their data back for free. GandCrab is a Trojan horse that encrypts files on the compromised computer and demands a payment to decrypt them.
GandCrab has been highly active since January, operating on an affiliate model. Its developers make the malware available as a service to interested parties in return for a share of the profits. This ransomware family spreads via multiple attack vectors, such as spam email, exploit kits and affiliated malware campaigns. In 2018, GandCrab has undergone several makeovers, particularly after Bitdefender released the v.1 decryption tool also developed collaboratively with local and international law enforcement agencies.
We believe that the best solutions against ransomware are:
- Vigilant users. An educated staff is the first line of defence against cybercrime.
- Up to date antivirus and antimalware programs
- Up to date Firewalls
And the most important, make sure you have regular full backups!
