This is Spartacus: new ransomware on the block

Analysis of the Spartacus ransomware describes its ransom notes and contact emails, appended file extension (.[[email protected]].Spartacus), dropped note (READ ME.txt), deletion of shadow copies via vssadmin, creation of a unique mutex ("Test"), persistence of the ransom window (SetForegroundWindow), and embedded RSA keys; notably, it requires victims to send an ID/public key and suggests decryption may be possible by extracting keys from memory, providing actionable IOCs.
