Microsoft warns Windows PC users of Russian hackers on hotel WiFi

Microsoft has issued a warning to Windows PC users about Russian hackers targeting individuals using hotel WiFi networks. The campaign, named CaptiveCrunch and attributed to the Storm-2945 group, focuses on corporate travelers and employs tactics like credential theft and malware distribution through compromised guest networks. Microsoft has been monitoring this activity since May, noting its impact on hospitality networks utilizing captive portals. Hackers have been redirecting users to counterfeit sign-in pages to steal credentials without phishing emails. The threat may also extend to Android devices, with hackers using deceptive techniques to manipulate users into downloading malicious APK files. The hackers employ fake verification checks and sign-in prompts, sometimes misleading users into Microsoft's legitimate authentication process to gain access to accounts. Microsoft has identified a specific remote-access trojan named CornFlake, which can record keystrokes, steal credentials, and capture screenshots. Recommendations for travelers include using mobile hotspots, avoiding updates through captive portals, strengthening authentication methods, and blocking unnecessary device-code authentication.

Scrappy RAT Malware Targets Chrome And Edge Users

A new remote access trojan (RAT) named msaRAT has been identified by Cisco Talos, linked to the Chaos ransomware group and built using Rust. It exploits Chrome and Edge browsers to disguise its traffic and evade detection. MsaRAT operates through a headless browser process, enabling remote code execution and facilitating ransomware deployment, data theft, and other malicious activities. It is typically installed via phishing emails or malicious files, making it resistant to standard browser patches. Cisco Talos recommends specific SNORT rules and a ClamAV signature for detection. Indicators of Compromise (IoC) include traffic to the IP address 172.86.126.18 and the domain is-01-ast.ols-img-12.workers.dev. The malware primarily targets large organizations, but individual users may also be at risk.

Active Exploitation Alert: Fake Bahrain Alert App Deploys Advanced Android Surveillance Malware Targeting Gulf Region Users

A cyber-espionage campaign has been identified involving a counterfeit Bahrain Alert Android application designed to surveil individuals in Bahrain and the Gulf region. The app masquerades as an official civil defense tool and employs social engineering tactics to compromise Android devices, extract sensitive data, and maintain remote access. It targets high-value individuals such as activists and journalists, particularly during civil unrest and missile alerts, leveraging trusted government branding to increase infection rates. The malware features a complex, multi-stage architecture with advanced evasion techniques and is distributed through phishing links and malicious websites. It initiates a four-stage infection process, ultimately installing a remote access trojan (RAT) that enables covert surveillance and encrypted communications. The malware can monitor device activity, capture credentials, and intercept communications, while also employing mechanisms to avoid detection and maintain persistence. The campaign primarily targets Bahraini citizens, exploiting fear during crises to encourage app installation. Although there are indications of Russian-speaking developers involved, there is no definitive attribution to a specific nation-state or APT group. Mitigation strategies include monitoring for suspicious app installations, user education on verifying app authenticity, and blocking known malicious domains.

15 years before Dishonored, Thief devs considered letting Garrett shrink himself rat-sized so he could scurry through drains and mouse holes

Corvo Attano, the protagonist of Dishonored, possesses the unique ability to inhabit various creatures, including rats, allowing him to access otherwise unreachable areas. This concept was considered for Thief: The Dark Project over a decade earlier. Both Thief and Dishonored feature stealthy protagonists embroiled in political intrigues, but Garrett from Thief lacks supernatural powers and relies solely on stealth. Thief emphasizes navigating environments without detection, while Dishonored allows for combat if stealth fails. Thief's focus on stealth mechanics has significantly influenced the genre. Recently, Thief has gained attention due to the announcement of a remaster, Thief: The Dark Project Remastered, by Nightdive Studios, which will include additional missions and enhancements. Original artist Daniel Thron is involved in revitalizing the game's cutscenes. A release date for the remaster has not been announced, but excitement within the gaming community is high.

LabubaRAT malware infiltrates Windows systems while posing as NVIDIA software

LabubaRAT is a newly identified Rust-based remote access tool (RAT) that disguises itself as NVIDIA software to facilitate operations on Windows systems. It establishes a reusable foothold for hands-on activity and can profile the host system, identify security tools, execute commands, transfer files, capture screenshots, and proxy network traffic. LabubaRAT retrieves its configuration at launch via command-line arguments or environment variables, allowing operators to specify parameters like the command-and-control server and API key at runtime. It maintains local state in a SQLite database and supports communication through HTTPS polling, Microsoft Edge WebView2, and DNS tunneling. The malware includes capabilities for command execution, file handling, and establishing persistence through a Windows Run registry key. The entry point for the attack is an executable named nvidia-sysruntime.exe, which masquerades as NVIDIA’s container runtime toolkit. LabubaRAT conducts thorough profiling of the host, checking for installed browsers and security products, and gathers information on the system's specifications. Blackpoint Cyber has shared indicators of compromise to help detect LabubaRAT activity.

New Millenium RAT version infects 62,000 Windows systems worldwide

A significant evolution of the Millenium remote access trojan (RAT) has impacted over 62,000 Windows devices across more than 160 countries. The latest version, 4.*, marks a departure from previous .NET-based versions and is attributed to a threat cluster known as Y2K Operators, with the creator identified as “ShinyEnigma.” There are 62,289 infected endpoints, with 39,730 infections occurring in the first quarter of 2026. The RAT is marketed as malware-as-a-service (MaaS) and promoted through underground forums and platforms like GitHub, with accessible pricing. Millenium RAT 4 is developed in native C++ and uses the Telegram Bot API for command-and-control communications. Its capabilities include stealing browser data, collecting system information, logging keystrokes, capturing screenshots and audio, accessing Telegram and Discord data, downloading additional payloads, and executing Windows or PowerShell commands. The malware ensures persistence by replicating itself in the %APPDATA% directory and creating an autorun registry entry. The malware is distributed through social engineering tactics such as cracked software, cryptocurrency utilities, hacking toolkits, OSINT tools, exploit builders, and Roblox-related cheats. Some campaigns have trojanized malware builders, infecting cybercriminals. One campaign used PDF-themed lures with a malicious Windows shortcut to download the RAT while displaying a legitimate document. Payloads often use filenames associated with Windows components or security software to blend into infected systems. Group-IB recommends avoiding untrusted executables, applying security updates, enabling multi-factor authentication, and monitoring for unusual autorun registry entries.
