Malicious Twitch Extension Steals OAuth Tokens from Nearly 31,000 Users

A browser extension posing as an enhancement for Twitch has been stealing OAuth authentication tokens from approximately 31,000 users across Chrome and Firefox. The extension, known as Twitch Enhanced Viewer or JeetBot, was discovered by researcher Kush Pandya of Socket. It promised 1080p streaming in restricted regions and an ad-free experience while covertly exfiltrating session tokens to attacker-controlled servers. The tokens were transmitted in plaintext via network-layer redirects, allowing full access to chat functions, private messages, and account settings. Both the Chrome version with around 30,000 installations since June 26, 2025, and the Firefox version with 604 users since July 7, 2025, remained available in official stores at the time of reporting. Users are advised to immediately disable the extension and revoke active Twitch sessions to invalidate stolen tokens.

No Hacker Genius Needed: One Login and 49 Minutes Suffice in Injective Supply Chain Attack

A routine update to the @injectivelabs/sdk-ts library for Injective blockchain wallets turned into a supply-chain trap within 49 minutes, stealing users' recovery phrases and private keys. The malicious version 1.20.21 was published on npm on July 8, 2026, after attackers compromised a long-trusted maintainer account and pushed code directly to the main branch. The backdoor, disguised as anonymous performance statistics collection, activated only when applications called PrivateKey.fromMnemonic() or PrivateKey.fromHex(), exfiltrating sensitive data via the X-Request-Id header to an attacker-controlled server mimicking Injective infrastructure. Eighteen Injective Labs packages were affected, with 87 downstream dependencies also pulling in the compromised library, which sees roughly 175,000 monthly downloads. Although developers rolled back the changes and released clean version 1.20.23 within 49 minutes, at least 310 malicious downloads were recorded, and cached copies may persist in build environments. Security researchers from Datadog, Socket, StepSecurity, and OX Security have advised immediate migration to the patched release and full key rotation for any wallets that interacted with the tainted code.
