According to the new report, the Bank of England is preparing talks with financial firms on Anthropic model risks as UK, U.S., and Canadian authorities coordinate on related cybersecurity concerns.
Bloomberg reported that concerns over cybersecurity risks tied to Anthropic’s ClaudeMythosPreview have expanded beyond the earlier U.S. emergency meeting to include planned discussions by the Bank of England with financial institutions. The update says UK regulators are coordinating with U.S. and other counterparts, while the Federal Reserve, U.S. Treasury, and Bank of Canada have also held meetings on related risks. This broadens the issue from a U.S.-focused warning to a cross-border regulatory response involving multiple major financial authorities.
