It is hard to believe, but ransomware is more than three decades old. While many would think that the ransomware mayhem started with the WannaCry attack of 2017, that is simply the most publicized example. Since then, dozens of ransomware strains have been utilized in a variety of cyberattacks.
AT&T Alien Labs has discovered a new malware targeting endpoints and IoT devices that are running Linux operating systems.
