Malicious Software & Ransomware
NCSC - The Rise of Ransomware

"Ransomware is nothing new. The first recorded example was in the late 1980s, but in the last 3 years there's been a real explosion in growth".

The video game studio posted to its twitter account on the 9th of February that and unidentified actor gained access to the network and encrypted some devices, but backups are intact.

The ransom note claims that the attacker has gained access to the source code of the recently released cyberpunk 2077 and Witcher 3.


They have also gained access to employee's personal data as well as locked them out of company's network restricting access to tools required for their work resulting in a massive loss of productivity for the company.
