About
Jamieson O'Reilly is an offensive security specialist and entrepreneur who has led high-stakes red team operations against some of the world's hardest targets, including banks, casinos, and government agencies. By emulating advanced persistent threat actors, he helps organisations close weaknesses before real adversaries can exploit them.
His career began in 2013 as a Security Engineer at Tenable, the same year he started publishing his research on bank-targeted RAM scraping malware, novel phishing techniques, and SQL injection bypass techniques. He went on to co-found Content Protection, serving as Director of Intelligence from 2014 to 2018.
Dvuln followed in 2016. The Australian, globally CREST-certified offensive security firm pressure-tests some of the world's largest brands against sophisticated attacks from offices in Sydney, Melbourne, and Brisbane.
His specialisations span offensive operations, exploit development, counter-detection, social engineering, HUMINT, and cryptography and AI security research. He co-authored the post-quantum encryption specification PPQM. Also in 2016, he identified and reported a critical security flaw in teleconference platforms used by the US Army, NASA, and CERN, among others.
By 2020, Jamieson had taken on a Project Lead role at the OWASP Foundation, where he leads the Penetration Test Reporting Standard and Cloud Security Testing Guide projects. He joined the CREST Australasia Advisory Council four years later.
2026 has been a defining year. Jamieson co-founded Aether AI, where he serves as CEO. Aether researches and develops frontier Attack AI models and agentic harnesses that continuously emulate adversaries.
Jamieson is also an active member of BT6, the elite frontier AI red team collective often described as the SEAL Team 6 of the latent space. His more recent public work includes the 2026 Grok and Moltbook research - the first documented case of Grok being socially engineered into verifying its own attacker-controlled third-party account. He also served as Security & Trust Advisor at OpenClaw during its rise as the world's fastest-growing software.
