He'd be proud of my using AI for these simple searches of his job history and breaches/leaks under his watch. Am sure there are others that didn't immediately show up.
AT&T joined April 2023; July 2024 snowflake leak, March 2024 shiny hunter leak
CIA joined May 2022; apparently they were happy to see him leave as he didn't stay long at what should have been a cushy job
AIG joined April 2019; Dec 2020/Jan 2021 Accellion file transfer breach
Wells Fargo joined July 2012; July 2017 edgar leak
Deloitte & Touche; joined late 2006
Pricewaterhouse Coopers LLP; worked 2005 to 2006 (sounds like he left Choicepoint leak)
Choicepoint joined roughly 2003 or 2004; breach 2005 for which he had to appear before FTC and was apparently the largest settlement/fine at the time
