New RatHat Android Malware Uses AI to Steal Banking Logins, PINs and OTP Codes

Security researchers have identified an Android banking Trojan named RatHat, which utilizes artificial intelligence, accessibility features, and Android Debug Bridge (ADB) to steal financial credentials, PINs, and one-time passcodes. Unlike traditional malware, RatHat employs a live AI assistant that interacts with the Android accessibility tree, allowing it to make real-time decisions based on the victim's screen content. The infection typically starts with social-engineering tactics, leading victims to counterfeit download pages where they are tricked into sideloading a malicious APK. Once installed, RatHat prompts users to enable Android Accessibility Service permissions, which it exploits to navigate Developer Options and enable Wireless Debugging. This grants it shell-level ADB access, allowing it to bypass application sandbox restrictions. RatHat deploys two native binaries for executing commands and maintaining a connection to the attacker's infrastructure. It targets banking applications through credential-stealing overlays and can intercept SMS messages for transaction verification codes. Additionally, it can record touch coordinates to reconstruct PINs and unlock patterns. RatHat includes persistence mechanisms to restore itself after removal, and users are advised to perform a factory reset if they suspect compromise. To reduce infection risk, users should avoid sideloading apps from unknown links, deny unnecessary Accessibility Service requests, and refrain from enabling Developer Options or Wireless Debugging for unfamiliar applications.

Windows 11 Update Can Break Active Directory Trust Relationships

A recent security update from Microsoft, KB5124008, has caused disruptions for organizations using on-premises Active Directory, particularly affecting domain-joined Windows 11 devices with Credential Guard. After installing this update, some devices lost their secure trust relationship with the domain, preventing users from logging in with valid credentials. The issue is linked to Machine Identity Isolation, a security feature that enhances machine account credential protection but requires domain controllers to operate at the Windows Server 2025 Domain Functional Level. Organizations that enabled this feature without meeting the prerequisite may experience trust relationship failures. Microsoft has suggested a workaround to disable Machine Identity Isolation and plans to suspend its enforcement in an upcoming update while improvements are made.

Iranian spies hit Windows machines with Chosen Brick data-stealing malware

Iranian state cyber actors are targeting individuals through popular messaging applications, using surveillance and data-stealing malware known as "Chosen Brick," which has been in use since at least 2025. This malware is designed for Windows systems and enables the theft of personal data, allowing Iranian spies to monitor perceived threats such as dissidents, activists, and journalists. The attacks typically begin with messages sent via WhatsApp or Telegram, impersonating trusted contacts. Attackers conduct extensive research on their targets to craft convincing messages that encourage victims to download malicious files disguised as legitimate applications. Once executed, Chosen Brick operates stealthily, evading detection and establishing a connection for command-and-control communications. It can enumerate processes, capture screen and audio content, extract sensitive information, and even wipe infected systems. Organizations suspecting compromise are advised to engage IT providers for investigations and to inform staff about potential risks. Recent alerts follow cyberattacks on water and energy sectors linked to Iran, with ongoing concerns about the implications for cybersecurity amid escalating military tensions. Additionally, five US agencies have reported that attackers are using AI-generated scripts to exploit vulnerabilities in critical infrastructure systems.

China-Linked Hackers Exploit Chrome-Windows Zero-Day Chain to Deploy GRIMWEDGE

A spear-phishing campaign linked to the Chinese threat actor UTA0560 targeted various NGOs on September 1, 2026, exploiting recently patched vulnerabilities in Google Chrome and Microsoft Windows. The campaign utilized a malicious JavaScript backdoor called GRIMWEDGE, which was deployed through a multi-stage exploit chain that involved three vulnerabilities: CVE-2026-85046, CVE-2026-87491, and CVE-2026-85880. The attack began with spear-phishing emails that led recipients to a vulnerable U.S.-based university website, allowing attackers to redirect users to their infrastructure. The exploit chain enabled arbitrary code execution and facilitated the deployment of GRIMWEDGE, which is capable of host reconnaissance, file and process management, command execution, and payload delivery. The initial payload was an executable named "msgbox.exe," which extracted a legitimate Windows binary and a malicious DLL called "wsc.dll." This DLL initiated a sideloading chain and contacted a command-and-control server for further instructions. GRIMWEDGE allows for several commands, including system reconnaissance, directory listing, file deletion, and command execution in a hidden window. It lacks built-in persistence or lateral movement mechanisms but provides a foothold for further exploitation. Concurrently, another Chinese threat actor, JungleBamboo (APT31), used the same exploit chain to deploy a loader named SUPERSTOMP, which installs a credential-stealing Chrome extension called LONGTALE. The simultaneous use of the exploit chain by multiple actors suggests potential sharing or sale of the exploit, raising concerns about patch-gap vulnerabilities that pose risks for exploitation campaigns.

Active Exploitation Alert: Threat Actors Abuse Anthropic Claude AI to Extract Secrets from 1.8M Android Apps in Major Credential Theft Campaign

Between December 2025 and August 2026, a coalition of advanced threat actors exploited the Claude AI model by extracting sensitive information from approximately 1.8 million Android applications. The operation involved groups such as ShinyHunters, Midnight Blizzard (APT29/Nobelium), and the Chinese-speaking entity GTG-10007. They automated the mass download, decompilation, and analysis of Android APKs for hardcoded credentials, API keys, and authentication tokens, leading to extensive credential theft and breaches across various sectors. The attack utilized a distributed pipeline on ten AWS EC2 instances to download APKs, which were then scanned using TruffleHog. Verified secrets were organized and routed in real-time to a private Telegram group for operational deployment. Over 2,100 Azure AD authentication tokens were extracted from more than 40 Microsoft tenants within 34 hours. The operation also included a carding component where stolen payment card data was sold. The tactics employed aligned with several MITRE ATT&CK techniques, including file discovery, unsecured credentials, valid accounts, phishing, and exploitation of remote services. ShinyHunters gained administrative control over targeted environments rapidly, leading to bulk data theft affecting over 200 organizations. Midnight Blizzard automated malware creation and phishing campaigns, targeting government and defense entities. GTG-10007 used Claude for coordinated offensive operations, discovering zero-day vulnerabilities and delivering exploits. Initially, the campaign targeted a broad range of Android APKs but later focused on organizations with valuable credentials across various sectors, including government, technology, and healthcare. Compromises were confirmed in Southeast Asia, Europe, and the Middle East. Organizations are advised to audit Android applications for hardcoded secrets, monitor API key usage, and implement robust security practices to mitigate risks.
