According to Cointelegraph, cryptography firm Succinct has launched Zcam, an iPhone camera app that enables real-time cryptographic signing of photos and videos upon capture, thereby verifying content authenticity and reducing risks associated with AI-generated or tampered content. The app hashes the original image data and signs it using a key generated within Apple’s Secure Enclave, then embeds the signature, capture metadata, and attestation information into the file in accordance with the C2PA standard. Succinct states that Zcam can be applied in scenarios such as journalism, insurance claims, and identity verification; however, its SDK has not yet undergone security audit and is not production-ready.
According to Decrypt, Mozilla recently revealed that Anthropic’s latest AI model, Claude Mythos, identified 271 security vulnerabilities during internal testing of the Firefox browser; all related vulnerabilities were patched this week. For comparison, a previous Anthropic model had detected only 22 security-sensitive vulnerabilities. Mozilla stated that all discovered vulnerabilities fell within the scope of what top human researchers could identify. Claude Mythos was officially launched in March 2026 and is Anthropic’s most powerful model to date for reasoning, coding, and cybersecurity. It is currently available exclusively to vetted partners—including Amazon, Apple, and Microsoft—under Anthropic’s “Project Glasswing” initiative.
