Washington, D.C. - U.S. Senator Elizabeth Warren (D-Mass.), Ranking Member of the Senate Banking, Housing, and Urban Affairs Committee, sent a letter to Secretary of the Treasury Scott Bessent urging the Trump Administration to strengthen the cybersecurity resilience of the financial sector amidst the growing risks of artificial intelligence (AI)-enabled cyberattacks. Recent development of AI models, such as Anthropic's "Claude Mythos," could supercharge the ability of malicious actors to identify and exploit security vulnerabilities in software - leaving sensitive financial data vulnerable to breaches and placing the broader financial system at risk of destabilizing cyber attacks. Ranking Member Warren pointed to data from 2025 that showed financial services institutions "suffered the most data breaches of any industry…for the second (consecutive) year."

"Recent advancements in AI technology have intensified cyber threats to the financial system-especially in light of the development of Mythos- and the Trump Administration should immediately reverse course on its deregulatory agenda, reverse the drastic cuts to the government's cyber resources, and promulgate stronger rules around bank supervision, vulnerability identification and remediation, third party vendor oversight, and threat information sharing," wrote Ranking Member Warren.

The Ranking Member continued: "To make matters worse, the Trump administration has repeatedly undermined cybersecurity resources across sectors. For example, the Administration has fired countless technologists from government agencies, which places Americans' and financial institutions' sensitive data at risk. Further, in 2025, the Trump administration dismantled the Cybersecurity and Infrastructure Security Agency (CISA), cutting the workforce by almost one-third."

Ranking Member Warren concludes by urging Secretary Bessent and the Trump Administration to reverse its deregulatory agenda on cybersecurity and institute new measures to ensure adequate bank supervision, oversight, and threat detection. She requested responses by June 16, 2026 to inform her legislative responsibilities with regard to the continued oversight of the banking system.
