Mary Ann Davidson
Oracle's long-serving chief security officer, best remembered for a 2015 blog post asking customers to stop looking for security holes in Oracle software.
Davidson, a former US Navy officer, ran Oracle's security organisation for more than two decades. In August 2015 she published "No, You Really Can't", aimed at customers who sent in vulnerability reports. The gist: the licence agreement forbids reverse engineering, and that includes doing it to find security flaws. Findings from static analysis of Oracle binaries were therefore a breach of contract, not a favour.
The post was gone within a day, with Oracle saying it did not reflect the company's view of its customers. By then it had already become one of the industry's most-quoted counterexamples to coordinated disclosure, and a stock argument for bug bounties: tell hackers to stop, and they stop reporting — not looking.
