GandCrab definition

GandCrab is a type of ransomware, a malicious software that encrypts a victim's files and demands a ransom to decrypt them. It was widely spread in 2018 and early 2019 and is notable for being one of the first ransomware to be sold as a service, a business model known as Ransomware-as-a-Service (RaaS). This business model meant that the creators of GandCrab didn't just infect systems themselves; they also allowed other cybercriminals to use their software in exchange for a cut of the profits.

How to avoid GandCrab

Although GandCrab is currently not an active threat, the ways to protect yourself against it also apply to many other types of ransomware. Here’s how you can protect your systems:

  • Regularly update software: Ransomware often exploits vulnerabilities in out-of-date software. Regularly update your operating systems and applications to the latest versions to protect against known vulnerabilities.
  • Use anti-malware tools: These tools can detect and remove many types of ransomware before they infect your system. Make sure to keep them updated as well.
  • Back up important data: Regularly back up your important files and data. Ideally, these backups should be stored on a separate system or offline to protect them from ransomware attacks.
  • Be cautious with emails and downloads: Many ransomware attacks begin with a phishing email or a malicious download. Don't open emails or attachments from unknown sources; be wary of any unsolicited emails asking for sensitive information.
  • Educate users: Make sure you and any other users on your systems know about the risks of ransomware, how it spreads, and how to avoid it.
