Ransomware victims who do not pay a ransom and have their stolen files leaked are now facing a bigger nightmare as other hackers and criminals sell and distribute the released files on hacker forums. This stolen data is very valuable to hackers as it contains user names and passwords, credit card statements, alleged tax information, and much more. BleepingComputer reached out to Brooks International by phone to warn them about the distribution of their data and ask related questions, but after speaking to someone never received a phone call back.
