The FBI issued a second warning this week to alert US companies of ProLock ransomware operators stealing data from compromised networks before encrypting their victims' systems.
The 20200901-001 Private Industry Notification seen by BleepingComputer on September 1st comes after the MI-000125-MW Flash Alert on the same subject issued by the FBI four months ago, on May 4th, 2020.
