One of the biggest global cyberattacks ever crippled about 200,000 computers in 150 countries at the weekend.
So-called ‘ransomware’ is a kind of malware that blocks access to a computer or certain data on it. The criminals behind the ransomware then demand that the owner of the computer (and / or its data) pay money for encrypting or releasing the data.
The global cybersecurity company Kapersky explains “WannaCry comes in two parts. First, it’s an exploit whose purposes are infection and propagation. The second part is an encryptor that is downloaded to a computer after it has been infected.”
If you suspect your IT system or individual pieces of equipment have been infected (by either WannaCry or other viruses), the best thing to do is contact your IT company. Here at Computerology, we can run tests immediately to assess the extent of the damage done and to advise you on the steps you need to take in response.
