FakePenny Ransomware

#FakePenny

Summary

In April 2024, Microsoft observed Moonstone Sleet delivering a new custom ransomware variant we have named FakePenny against a company it previously compromised in February. FakePenny includes a loader and an encryptor. Although North Korean threat actor groups have previously developed custom ransomware, this is the first time we have observed this threat actor deploying ransomware.
