What is Ransomware and How You're a Target?

Ransomware is malicious software (malware) that a cyber criminal places on a victims computer via the computer's Operating System. The ransomware allows the cyber criminal to have sole access to the victims computer, preventing the victim from being able to access the computer and its data. The cyber criminal/ hacker will then request money in exchange for granting computer access back to the victim.

How Does Ransomware Get on a Computer?

The most common way ransomware gets on a victims computer is via phishing email:

  • A phishing email is an email that has a downloadable attachment which is the ransomware.

The email will attempt to look innocent or similar to an email the victim is expecting. The victim will then download the malicious software attachment, thinking it is something else.

The Victim of Ransomware

Average citizens can be victims of ransomware; however, the ideal target for a computer hacker will be businesses. Ransomware is a large IT security issue for most businesses. These businesses often find that they cannot afford to have their data frozen due to the loss in company revenue.

How to Prevent Ransomware

The best cyber security method to preventing ransomware is to not open unfamiliar emails. This can be tricky:

  • Many phishing emails look similar to reputable emails with a character or two changed: joe@realcompany.co.za can be changed to joe@reallcompany.co.za

Possible victims need to look at every letter and number in the email to see if they match up to the correct email.

The Black Cat ransomware organization infecting Shell with ransomware. This affected and shut down over two hundred gas stations in Germany.
