Cronos-Crypter is an open-source crypter publicly available on GitHub. The crypter applies AES encryption or XOR obfuscation to a selected payload before storing it as a .NET resource of a final generated .NET executable payload. Cronos-Crypter contains multiple capabilties for persistence and defense evasion. An operator may select persistence via a Windows Registry autorun key or a Scheduled Task. An operator may also select for decrypted payloads to be injected into a newly spawned copy of itself or regasm.exe. To further evade defenses, the operator may also specify to introduce a sleep delay, bypass AMSI controls, and avoid execution within virtual machine environments.
