First, it’s important to understand what “ransomware” is. Ransomware is computer malware (a malicious program) that installs secretly on a person’s computer, executes a cryptovirology attack (installs a virus) that harms the computer or data on the computer, and demands a ransom payment to restore it. More advanced programs actually encrypt the victim’s files which make the unreadable and also demands payment to decrypt them.
The history of ransomware started around 2005 with the first know attack using a program called “Gpcoder”. Since them, the use of ransomware has increased exponentially.
What is the best way to defend against a ransomware attack?
- Prepare in advance
- Run the appropriate anti-virus software on all critical systems
- Ensure that data is backed up onto computers not connected to your critical systems
