Hayley Chang serves as Director and Associate General Counsel for Cybersecurity and Investigations at Meta (formerly Facebook), where she leads the legal team focused on protecting the company and its 3.6 billion users from malicious activity in cyberspace.
Prior to transitioning to the tech industry, Ms. Chang held several senior roles in government – all focused on law enforcement, national security, and cybersecurity. Most recently, she served as Deputy General Counsel of the FBI, where she oversaw the 9/11 litigation and contributed significantly to the investigation of the 2019 Pensacola terrorist attack.
Ms. Chang previously served as Deputy General Counsel for Cyber and Technology at the U.S. Department of Homeland Security, where she led the Department’s successful effort to obtain passage of the Preventing Emerging Threats Act of 2018. Ms. Chang testified before Congress in support of the new law, which enables federal law enforcement to use advanced technology to counter emerging threats from drones. She also led the Department’s legal strategy to leverage new cyber authorities to mitigate a Russia-based cybersecurity threat. This initiative resulted in a complete ban of all Kaspersky products across the federal government. The Department prevailed against subsequent legal challenges at the district court and appellate levels. These and other cutting-edge efforts culminated in the successful creation of the Cybersecurity and Infrastructure Security Agency (CISA).
Ms. Chang’s government service also includes six years as a federal prosecutor, where she won the Distinguished Service Award and the Director’s Award for her successes in complex trials. Additionally, in two separate rounds of government service, Ms. Chang played critical roles in efforts to enhance CFIUS authorities, with the successful passage of the Foreign Investment and National Security Act (FINSA) in 2007 and the Foreign Investment Risk Review Modernization Act (FIRRMA) over a decade later.
Ms. Chang’s private practice experience includes litigation, appeals, and government investigations, and she was the General Counsel for a financial technology company designed to serve U.S. veterans.
Ms. Chang is a graduate of Cornell Law School, where she served as an editor of the Cornell Law Review. She received her bachelor’s degree from Hillsdale College. Following law school, she clerked for Chief Judge Timothy Tymkovich on the United States Court of Appeals for the Tenth Circuit.
