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.

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.

13 Malicious Packagist Packages Target Unpatched iPhones to Steal Crypto Wallet Seeds

Trojanized Packagist themes inject JavaScript into Vietnamese streaming sites, exploiting unpatched iPhone WebKit and kernel flaws to install spyware and steal crypto wallet seeds.

Socket researchers found 13 malicious Composer theme packages across five vendor namespaces (including vsmov, vsphim, and ophimcms) that inject JavaScript into Vietnamese movie and comic streaming sites. On iPhones running iOS 18.4-18.6.x, the injected code fires a WebKit-to-kernel exploit chain using CVE-2025-31277 and CVE-2025-43529, pivoting through the GPU process and the AppleM2ScalerCSCDriver IOKit user client to gain kernel read/write. Since around August 12, 2026 the payload also steals cryptocurrency wallet seeds and mnemonics from Bitget, BitKeep, Bitpie, Phantom, Tonkeeper, Trust Wallet, and OKX, alongside keychain databases, Wi-Fi passwords, SMS, photos, cookies, and location history, uploaded via HTTPS to rotating C2 domains. The group is believed to be Vietnamese-operated, hosts exploits on Funnull infrastructure, and Apple patched the kernel escape flaw in iOS and macOS 26.1.
