Cisco Talos Discloses Autonomous Windows Malware: Four AI Models Direct Each Attack

Cisco Talos has disclosed a Windows implant called CLOSEDQUORUM, which automates cyberattack execution using four advanced commercial large language models: DeepSeek, Qwen, Mistral, and Google Gemini. The implant is a 16.4-megabyte executable that conducts reconnaissance on the system and formats the gathered data into prompts for the AI models. Each model votes on one of four actions: steal, inject, persist, or move, with the action receiving the most votes being executed. When stealing, CLOSEDQUORUM targets three credential stores, dumping LSASS memory and retrieving saved passwords from browsers and cryptocurrency wallets. The stolen data is encrypted and sent to the operator via Discord. For injection, it uses Early Bird APC injection or process hollowing based on model responses. The persist action creates three mechanisms for longevity, including a Registry Run key, a scheduled task, and a WMI event subscription. CLOSEDQUORUM evades detection by suppressing ETW telemetry and delaying activity to avoid sandbox analyses. It connects to legitimate API endpoints, making blocking ineffective without disrupting enterprise applications. Talos recommends behavioral combination detection strategies and the use of a YARA rule for detection. The CAIRN toolkit has been introduced to detect AI-integrated malware without executing binaries. Unlike previous AI-assisted malware, CLOSEDQUORUM removes human decision-making from the attack process.

8 Antivirus Software for Mac: Our Top Picks by Use Case (2026)

Apple provides built-in security features for macOS, including XProtect, Gatekeeper, and automatic malware removal, which contribute to the safety of Macs. However, these protections do not effectively address threats like infostealers, phishing, and adware. For enhanced security, third-party antivirus solutions are recommended. Bitdefender is noted for its strong detection rates and minimal system impact, making it suitable for most users. Intego specializes in Mac-specific threats and is ideal for users focused solely on Apple products. ESET and Trend Micro are recommended for businesses needing centralized management. F-Secure is recognized for its privacy-focused approach, while Norton offers a comprehensive suite of security features. AVG provides free real-time protection suitable for low-risk personal use, but may not be adequate for business needs. CleanMyMac is a maintenance tool rather than a traditional antivirus, focusing on system cleanup and optimization. Users should avoid running multiple real-time scanners simultaneously and ensure they purchase appropriate licenses for business use. It's important to evaluate the necessity of additional features and consider long-term pricing when selecting antivirus software.

Four REVSTEALER-Linked Modules Disable Windows Update and Defender to Run a Crypto Miner

Elastic Security Labs has identified four previously undocumented programs associated with REVSTEALER, a Windows information stealer that persists on infected machines after self-deletion. The programs are ProManager, WinUpdate, SoftManager, and LockAppHost, each with distinct functionalities. ProManager steals wallet files and logs passwords, WinUpdate monitors the clipboard for cryptocurrency addresses, SoftManager acts as a reverse proxy, and LockAppHost executes a cryptocurrency miner after disabling Windows Update and Microsoft Defender. REVSTEALER has been marketed as a commercial infostealer since February 2026, exfiltrating sensitive data such as browser passwords, cookies, and cryptocurrency wallet information. It deletes itself after reporting its activities but leaves the four programs installed for persistence. These programs share build tradecraft with REVSTEALER, including the use of identical packers and runtime function resolutions. REVSTEALER primarily spreads through game-cheat lures and disguises itself as pirated software. It employs evasion techniques to resist analysis, including checking for sandbox environments and using indirect system calls. Users are advised to avoid unofficial software and to follow specific steps if infected, such as re-enabling Windows Update services and changing passwords. Indicators of compromise include SHA-256 hashes for REVSTEALER and its associated programs, as well as domains linked to their command and control servers.

Hackers Are Using a Fake Roblox Cheat To Access Your Webcam and Steal Data

Roblox is facing privacy concerns due to spyware disguised as an "undetected" version of the Xeno Roblox cheat tool. This malware can access screens, record keystrokes, and activate webcams, allowing attackers to execute remote commands. The infection begins when users download a file resembling a legitimate Xeno installation, often shared on platforms like Discord. The malware, previously known as Powercat, has evolved and operates in three stages: 1. The user executes a file named Xeno.exe, which checks for Java and extracts it if necessary. 2. The malware runs a JAR file disguised as decompiler.exe, performing checks to avoid detection. 3. It masquerades as a legitimate Windows DLL file, logging activities and attempting to escalate privileges. If successful, the malware can control the victim's system, access webcams, log keystrokes, and steal sensitive information, including cryptocurrency wallet credentials. To protect against this spyware, users are advised to avoid unofficial cheats, use antivirus software, refrain from clicking unsolicited links, enable two-factor authentication, inspect User Account Control prompts, and consider identity theft protection services.

CrashStealer Mac malware steals passwords and wallets

A sophisticated new malware targeting Mac users, named CrashStealer, has been discovered by security researchers at Jamf Threat Labs. It masquerades as Apple's legitimate crash-reporting software and was first identified in May 2026, with active attacks detected by early July. CrashStealer is designed to extract sensitive information, including browser credentials, password manager data, and cryptocurrency wallet information, and can copy the Mac login Keychain. It uses native C++ programming, encrypts collected files, and employs anti-debugging features. The malware is distributed through a disk image labeled "Werkbit Setup," which features a polished installer that bypasses Mac security warnings by using a valid Apple Developer ID and notarization ticket. Once opened, it connects to GitHub for commands and downloads a script that installs a second disk image named CrashReporter.dmg, which mimics an Apple system component. CrashStealer presents a fake password prompt resembling a legitimate macOS request, verifying entered passwords locally. It targets data linked to various browsers and password managers, scanning for approximately 80 cryptocurrency wallet extensions and 14 password managers. Stolen data is stored in hidden folders, encrypted using AES-256-GCM, and packaged into hidden ZIP archives before being uploaded. Warning signs of infection include a website requiring a meeting PIN for download, unexpected password prompts, and unfamiliar apps requesting Full Disk Access. Users are advised to download apps from verified sources, avoid overriding security warnings, pause before entering passwords, review app permissions, install security updates, use antivirus software, and act quickly if they installed Werkbit Setup.

Retro gaming fans are the new target for fake GitHub malware

Retro gaming enthusiasts should be cautious when exploring GitHub projects for tools or plugins, as cybercriminals may disguise malware as homebrew software. A specific incident involved a project called EQVita, which pretended to be a free audio tool for PlayStation Vita but actually contained Windows malware. The downloaded file included three files: Launch.bat, luajit.exe, and x64.txt, with the latter concealing a hidden script that connected to the attacker's server upon execution. This scam is part of a broader trend where counterfeit GitHub repositories distribute SmartLoader malware, which retrieves additional malicious software aimed at stealing passwords and cryptocurrency wallets. The PS Vita community, despite the console's production ceasing, remains active in modding, making it a target for attackers. Legitimate plugins typically come in Vita-compatible formats, while fake ones may feature polished marketing materials and AI-generated descriptions. Users are advised to verify sources, be cautious of suspicious downloads, and utilize security tools like Malwarebytes. If someone has executed the malicious EQVitav1.3.zip file, they should conduct a malware scan, change important passwords, and monitor accounts for unauthorized access. Indicators of compromise include the domains https://github.com/Voistace/EQVita and https://voistace.github.io, and the IP address 85.137.52.21.
