Crane Hassold is a Principal Security Researcher on the MDO Social Engineering Threats team at Microsoft, where he focuses on collecting intelligence on email-based threats targeting enterprise customers. He began his career at the Federal Bureau of Investigation, spending most of his 11 years there in the FBI’s Behavioral Analysis Units. In 2012, he helped establish the FBI’s Cyber Behavioral Analysis Center, which applied traditional behavioral analysis techniques used for decades to investigate serial violent crimes to the cyber domain, combining them with technical expertise to gain a more holistic understanding of cyber threats and threat actors. After transitioning to the private sector in 2015, Crane built and led threat intelligence teams at four different companies, including Uber, Abnormal AI, Agari, and PhishLabs, before joining Microsoft in 2024.
