One Exploit Chain, Two Espionage Campaigns: Chrome and Windows Under Fire

Two China-linked APT groups reused identical Chrome/Windows zero-day chain against NGOs, deploying GRIMWIDGE backdoor and LONGTALE credential-stealing extension.

Volexity reports that China-linked actors UTA0560 and JungleBamboo (APT31/TA412) ran byte-identical Chrome/Windows exploit chains against NGOs starting September 1, 2026, combining Chrome type confusion CVE-2026-85046, WebAssembly sandbox escape CVE-2026-87491, and Windows kernel flaw CVE-2026-85880. The Chrome bug was fixed in Chromium source but not yet shipped to Chrome users, making it an effective zero-day with an unusual patch gap. UTA0560 delivered the in-memory GRIMWEDGE JScript backdoor, while JungleBamboo deployed the SUPERSTOMP loader installing LONGTALE, a malicious Chrome extension disguised as Google Gemini that steals cookies, session tokens, and keystrokes. Volexity assesses with low confidence the exploit chain was sold or shared among different Chinese end-users.

KREMLIN Banking Malware Bypasses Chrome Security to Steal Banking Sessions

Elastic Security Labs details KREMLIN, a Brazilian banking malware that implants malicious Chrome and Edge extensions by forging Chromium integrity values to steal banking sessions.

Elastic Security Labs tracks the KREMLIN banking malware operation as REF9334, active since at least May 2025 across seven campaigns primarily targeting 12 Brazilian banks. The malware is installed by a victim-run JavaScript loader, achieves scheduled-task persistence, and side-loads a malicious DLL via SentinelOne's SentinelMemoryScanner.exe. It modifies Chrome and Edge Secure Preferences files, enables developer mode, and regenerates Chromium MAC values to silently install extensions, while extracting browser encryption material including the newer App-Bound OSCrypt key. An Ethereum smart contract serves as a dead-drop resolver for C2 config; Elastic disrupted over 1,500 infections via a canary domain.

Malicious Twitch Extension Exposes 31,000 Users' OAuth Tokens

Malicious Twitch extension 'Twitch Enhanced Viewer | JeetBot' forwarded live OAuth session tokens of roughly 31,000 users to Russian JeetBot proxy servers.

Socket research found the cross-store extension Twitch Enhanced Viewer | JeetBot (about 30,000 Chrome users and 552 Firefox users) routing Twitch video requests through JeetBot proxy servers with the account-scoped OAuth bearer token appended in cleartext as a URL query parameter. Version 4.x builds, including 4.8 from January 2026, posted captured tokens to dedicated set-token endpoints on JeetBot infrastructure with backups on two Deno services. Token holders can read and send whispers, post in chat, and spend channel points without a password or 2FA; listings were still live at publication and users are advised to remove the extension and re-authenticate.

Google Pixel phones pwned in zero-click attacks

CISA added actively exploited zero-click Pixel modem flaw CVE-2026-58704 to its KEV catalog, giving federal agencies three days to patch.

Google disclosed CVE-2026-58704, a high-severity improper authorization flaw in Pixel phones' cellular modems that bypasses permission checks and escalates privileges with no user interaction, noting limited, targeted exploitation. CISA added it to the Known Exploited Vulnerabilities Catalog with a September 19 deadline for federal agencies. Such zero-click modem bugs are a frequent vector for commercial spyware. The Register also notes two recently KEV-listed Chromium V8 flaws, CVE-2026-85046 and CVE-2026-87491, which Proofpoint says four espionage groups chained in intrusions.

The sexy AI-powered dating app scams are here

Anthropic exposed a network of roughly 28 AI-driven dating apps using autonomous personas and gig workers to defraud paying users.

Anthropic threat intelligence uncovered a fraud network of around 28 dating apps after a prepaid account sent over 100,000 Claude API requests daily, with most chats run by autonomous AI personas and no human agent. Researchers Matthew Gore-Kormanik and Anthropic's Chris Cronbaugh documented apps including Dora, Romi, and Doni, which monetize conversations via coins; gig workers were hired only to pass liveness checks and select pregenerated replies. An operations manual written in Chinese was found inside the Doni app, and Anthropic published findings in its September 2026 AI misuse report.

North Korean IT Workers Use AI and Remote Desktop Tools to Fake Technical Interviews

Silent Push links a Discord recruitment scheme to North Korean IT workers using AI, remote desktop tools and on-camera proxies to pass technical interviews.

Silent Push assessed with moderate-to-high confidence that a representative known as Tec Guru, recruiting on-camera proxies via a Mouse Review Discord advertisement, is a North Korean IT worker. The scheme proposed a 65/35 revenue split with the hidden worker, live coaching through Google Meet, AI tools including ChatGPT to fill knowledge gaps, and remote access tools such as AnyDesk, TeamViewer, and Chrome Remote Desktop during coding exercises. Fraudulent hires can gain insider access enabling data theft, extortion, payroll fraud, and sanctions exposure; a July 31, 2026 multinational warning urged stronger identity checks and payment scrutiny.

RatHat Abuses Android Wireless Debugging to Gain Shell Access and Steal Banking PINs

New Android banking trojan RatHat abuses Wireless Debugging to gain shell access and steals banking PINs and OTPs via raw touch capture.

Zimperium and zLabs analyzed RatHat, an Android banking malware linked to China-based actors that chains Accessibility abuse and Wireless Debugging to obtain a local ADB shell without a host computer. Masqueraded Go binaries in /data/local/tmp provide persistence and an FRP reverse tunnel, while a getevent-based collector maps touch coordinates to PIN pads and pattern locks using locateValues.json layouts. It targets banking, crypto, WeChat and Alipay apps through smishing, malicious ads, and HTML overlays, and serializes the accessibility tree for a generative AI assistant to automate on-screen actions. Layered anti-analysis includes malformed DEX, a padded manifest, and debugger, Frida, and emulator checks.
