What is ransomware?

Ransomware presents a serious threat to business data, as it has the ability to lock access to files until the victim pays the attacker. It is a form of malware that works by encrypting user data until the correct decryption key has been entered. However, users can only gain access to that key by paying the ransom the attacker has set.

OR It’s a malware (a Trojan or another type of virus) that locks your device or encrypts your files, and then tells you that you have to pay ransom to get your data back. It’s not cheap, and there’s no guarantee of success. If you become a victim of ransomware.

How does it work?

Ransomware is often attached via an email, a computer programme that’s been infected or a website which has been compromised. However there have also been examples of more sophisticated infections.

Prevention advice

Do not click or open any suspicious attachments, links. If in doubt ask your IT support team.

Internet Security software, should be updated, as should operating systems.

User created files should be backed up routinely and preserved off the network.

The first recorded ransomware attack occurred in 1989, when evolutionary biologist Joseph Popp infected floppy disks with the AIDS Trojan and distributed them to fellow researchers. The malware didn’t run immediately, but instead waited until victims booted their PCs 90 times. Finally, it encrypted all system files and asked users to pay $189 to undo the damage. Luckily, experts came up with tools to remove the malware and decrypt infected files.
