What happened
Multiple security stories: Zimbra urged customers to patch a critical XSS vulnerability in its Classic Web Client. Supply-chain attacks and credential stealers proliferated — an Injective Labs SDK npm package was used to publish a wallet stealer that exfiltrates private keys/mnemonics, and fake Paysafe/Skrill SDKs on npm and PyPI delivered credential-stealer malware. New phishing and extortion operations (Forg365 and Helix) use AI-assisted lure generation, AiTM/device-code techniques and MFA abuse to target Microsoft 365 and SharePoint accounts. Microsoft patched the “RoguePlanet” Defender 0‑d
