Avaddon ransomware is the latest cybercrime operation to launch a data leak site that will be used to publish the stolen data of victims who do not pay a ransom demand.
Since the Maze operators began publicly leaking files stolen in ransomware attacks, other operations soon followed suit and began creating data leak sites to publish stolen files.
These sites are designed to scare victims into paying a ransomware under threat that their files will be leaked to the public. If publicly released, this data could expose financial information, personal information of employees, and client data, which leads to a data breach.
