  • Check for SeImpersonatePrivilege on service accounts; the exploit explicitly requires and checks for this privilege before proceeding.
  • Detect reflective DLL injection of rottenpotato.x64.dll or rottenpotato.x86.dll into a hidden notepad.exe process spawned from a Meterpreter session.
  • Monitor for Net-NTLMv2 authentication requests being forwarded/reflected between DCOM/RPC services on the same host, which is the core exploitation mechanism.
  • Alert on CLSID-based DCOM activation requests originating from low-privileged service accounts that result in SYSTEM-level token impersonation (Juicy Potato variant requires a CLSID string).
  • Audit for use of the Meterpreter incognito module following exploitation, as the exploit guide recommends token impersonation post-shell.
  • ·The Juicy Potato variant (ms16_075_reflection_juicy) requires a valid CLSID string to be supplied; without it the exploit will not function.
  • ·Windows 10 builds after 1803 (build 17134) and all Windows Server 2019 versions are NOT vulnerable to the Juicy Potato variant.
  • ·WOW64 sessions are explicitly unsupported; session architecture must match target architecture or the exploit will abort.
  • ·The exploit requires the attacker to already have a valid local logon session; remote exploitation is not possible.
