What is ransomware?

Ransomware is a type of malicious software (malware) designed to block access to a victim's system or files, usually by encrypting them, until a ransom is paid. It's a growing cyber threat that affects individuals, businesses, and government institutions.

Once a device is infected, the attacker demands payment in exchange for a decryption key. Victims are typically warned that if the ransom isn't paid, their files will be deleted or made public.

How does ransomware work?

Ransomware often spreads through:

  • Phishing emails with malicious links or attachments
  • Drive-by downloads from compromised websites
  • Exploiting vulnerabilities in outdated software or operating systems

How to prevent ransomware attacks

  • Keep software and systems updated to patch known vulnerabilities.
  • Use email filtering and endpoint protection to block malicious content.
  • Educate employees about phishing and suspicious attachments.
  • Backup your data regularly and store backups offline or in secure cloud locations.
  • Limit user access to only what they need to do their job to reduce the impact of a breach.
  • Use multi-factor authentication (MFA) wherever possible.
