Hardware Keystores for AI Agent Signing Workflows: A Zero-Trust MCP Enforcement Architecture

AI agents performing cryptographic operations signing Git commits, authenticating API calls, issuing certificates currently store private keys in software-accessible locations: plaintext files, environment variables, or container memory. Any process with sufficient read privileges can extract the...

Google Password Manager Attacks Could Let Malware Hijack Passkey-Protected Accounts

Malware running as an ordinary user on a Windows machine can sign into a victim's passkey-protected accounts without a fingerprint, a PIN, or anything at all appearing on the victim's screen. Unit 42 detailed three attack paths against Chrome's Google Password Manager cloud authenticator, which i...

Synapse's invalid device keys degrade federation functionality

ImpactLack of validation for device keys in Synapse before 1.138.3 and in Synapse 1.139.0 allow an attacker registered on the victim homeserver to degrade federation functionality, unpredictably breaking outbound federation to other homeservers.

CVE-2026-50108

The Naxclow platform API that returns device relay registration details exposes a persistent credential without verifying that the requester is the legitimate device or owner. An actor able to present a platform-valid request signature can retrieve credentials for arbitrary devices and register o...

CVE-2026-28742

Naxclow devices use a uniform request-signing scheme based on a hard-coded, platform-wide salt embedded in every firmware image. Once this salt is recovered from any device, an attacker can generate valid signatures for arbitrary device or account operations due to the absence of per-device keys,...

CVE-2026-28742

CVE-2026-28742 relates to Naxclow IoT Platform devices using a uniform, hard-coded platform-wide salt for request signing embedded in firmware. The lack of per‑device keys, server-side nonce tracking, or replay protections allows recovered salts to enable valid signatures for arbitrary device or ...
