VoidStealer uses debugger trick to steal Chrome master key

🔓 VoidStealer, an information stealer offered as MaaS since mid‑December 2025, uses a debugger-based technique to extract Chrome's v20_master_key directly from memory. The malware starts a suspended, hidden browser process, attaches as a debugger, and waits for the target chrome.dll to load before setting hardware breakpoints on an instruction that references the key. When the breakpoint triggers during startup decryption, VoidStealer reads the register pointer and uses ReadProcessMemory to capture the plaintext key without privilege escalation. Gen Digital reports this is the first infostealer observed in the wild using this approach.

FBI: Russian-Linked Phishing Targets Signal, WhatsApp

🔒 U.S. agencies warn that threat actors aligned with Russian intelligence are conducting targeted social-engineering phishing campaigns to compromise commercial messaging apps such as Signal and WhatsApp. The attacks have led to unauthorized access to thousands of accounts and involve impersonation of support personnel to request SMS codes, verification PINs, or to deliver malicious QR links. Victims who provide codes can lose account control, while those who scan attacker-controlled QR codes may have past and future messages exposed. Authorities advise never sharing verification codes and regularly reviewing linked devices in app settings.

CanisterWorm: npm Worm Spreads via Trivy Supply-Chain Attack

🛡️ The actors behind the Trivy supply-chain compromise are now suspected of seeding a self-propagating worm called CanisterWorm, which uses an ICP canister (Internet Computer blockchain smart contract) as a decentralized dead drop for command-and-control. The chain abuses an npm postinstall hook to drop a Python backdoor and establishes persistence via a masquerading systemd user service that restarts automatically. A new variant harvests local npm tokens during postinstall and launches an automated propagation routine, turning compromised developers and CI pipelines into unwitting distributors.

Infrastructure Already in the Espionage Collection Path

🔍 Enterprises now sit directly in adversaries' collection paths: they may not be primary targets but their shared telecom, cloud, MSP, and identity dependencies are being exploited upstream. Commercial spyware like Predator and state‑aligned groups documented in Singapore's February 2026 telco breaches show how device and backbone compromises create persistent, upstream access. CISOs must assume provider compromise, demand attestation, harden session and identity layers, and shift detection to low‑noise, long‑duration intelligence operations.
