A recent data breach at Mercor has resulted in the theft of 4TB of voice samples from 40,000 AI contractors, which can be used to create synthetic voices for various malicious purposes. The breach is particularly concerning because it combines voice samples with government-issued identity documents, making it easier for attackers to use the stolen data. The article discusses the potential risks and consequences of this breach, including bank verification bypass, vishing, and deepfake video calls. Contractors who were affected by the breach are advised to take steps to protect themselves, such as self-auditing their public audio footprint and setting up verbal codewords with family and finance contacts.
