Fake AI trading agent steals crypto wallet passwords

Fake AI crypto trading agent sites deliver Needle Stealer, which replaces browser wallet extensions to steal wallet passwords, HP reports.

HP researchers tracked campaigns between April and June 2026 in which a fake AI trading agent site, tradingclaw[.]pro, distributed a Microsoft-signed OLEView executable that DLL side-loads a malicious iviewers.dll and launches Needle Stealer via process hollowing. Needle replaces one of seven browser wallet extensions, including MetaMask, Coinbase Wallet, and Phantom, to capture wallet passwords. Related campaigns used QR-code invoice phishing leading to fake OneDrive pages, Phantom Stealer sold as a penetration testing tool with VBScript-to-PowerShell steganographic loaders, and image-hidden payloads delivering XWorm, PureLogs Stealer, and Formbook; a perceptual-hash VirusTotal search found about 400 distinct rigged images.

KREMLIN Banking Malware Infects Over 1,500 Systems With Malicious Chrome Extension

Elastic tracks KREMLIN banking malware that used fake Brazilian bank JavaScript lures to deploy malicious Chrome and Edge extensions on 1,515 systems.

Elastic researchers tracked the KREMLIN banking malware operation across seven campaigns over 15 months, infecting 1,515 systems, 98.75% of them in Brazil. Portuguese-language lures posing as bank records and invoices deploy a hostile 'AVSync' extension into Chrome and Edge profiles that harvests passwords, session cookies, keystrokes and screenshots. Loaders check for sandboxes, create scheduled tasks and fetch fresh infrastructure from an Ethereum smart contract; a network canary takeover temporarily disrupted infections.

Chinese hackers use SparroWocky malware in govt espionage attacks

ESET reports China-linked FamousSparrow deployed a new modular backdoor, SparroWocky, in year-long espionage attacks on Latin American government organizations.

ESET researchers observed FamousSparrow using SparroWocky, a modular C++ backdoor replacing the earlier SparrowDoor tool, against government targets in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico, and Venezuela. Deployed via DLL side-loading with an RC4-encrypted payload mapped in memory, it captures screenshots, acts as a TCP proxy, and hooks CreateThread so malicious threads appear as AnimateWindow. Persistence uses a ProcAuditManager Windows service or SnapCart registry key; ESET tracked at least 18 C2 addresses and published IoCs.

The extension you never installed: KREMLIN forges Chrome's own integrity checks to steal banking sessions

Elastic details KREMLIN, a Brazilian banking malware whose malicious Chrome/Edge extension forges Chromium integrity checks to steal sessions.

Elastic Security Labs tracked operation REF9334 and its KREMLIN toolkit, a Brazilian banking malware campaign impersonating twelve banks across seven campaigns since May 2025. The infection chain uses multi-stage obfuscated JavaScript loaders with sandbox checks (file and process counting), scheduled-task persistence, and an Ethereum smart contract acting as a dead-drop resolver for C2 and payload URLs, abusing Archive.org for hosting. The malicious browser extension bypasses Chromium integrity mechanisms by manipulating Secure Preferences and regenerating required HMACs and App-Bound encrypted hashes. Threat Command disrupted over 1,500 infections by registering the kill-switch canary domain.

Hackers Abuse YouTube Gaming Channels and SEO Poisoning to Deploy RATs and Chrome Hijacker

Unit 42 exposed CL-CRI-1171, a pay-per-install operation using YouTube gaming channels and SEO poisoning to deliver RATs and a Chrome hijacker.

Palo Alto Networks Unit 42 identified over 10,000 OfferLoader samples and 11 YouTube channels pushing trojanized installers via gaming lures and SEO-poisoned searches for tools like WinDirStat and Bluetooth drivers. Trojanized Inno Setup installers spawn three payload branches: Insomnia RAT (dual Node.js/Python backdoor that disables Microsoft Defender), ARKTunnel (undocumented RAT hiding its payload in a bitmap image and tunneling TCP/UDP), and Docro Hijacker (alters Chrome protected preferences to hijack search and affiliate links). The pay-per-install model sells each infection to multiple buyers, reaching gamers as well as corporate and government endpoints.
