What I'm looking for

I’m looking to run realistic adversary emulation—red teaming, AD exploitation, C2 operations, and phishing—while delivering actionable reports mapped to MITRE ATT&CK and supporting remediation to reduce enterprise risk.

I’m a Red Team operator focused on Active Directory exploitation, red teaming, and offensive security research, especially AD attack paths, Kerberos abuse, domain privilege escalation, and lateral movement.

At Payatu Security Consultancy, I’ve run full-scope red team engagements (APT emulation, assumed breach assessments, and purple teaming), delivered phishing campaigns and C2 operations, and mapped reporting to the kill chain and MITRE ATT&CK with remediation guidance.
