According to Trend Micro, LockerGoga is a ransomware that has been used in multiple attacks, most notably against Altran Technologies and Norsk Hydro. It encrypts a range of documents and source code files but certain versions had little to no whitelist that would protect import system files such as the Windows Boot Manager.
