Cloudflare, in collaboration with Microsoft and international law enforcement, has dismantled the infrastructure of LummaC2, an information-stealing malware service. This initiative led to the seizure and blocking of malicious domains and disrupted digital marketplaces used by criminals. Lumma Stealer operates as a subscription service providing threat actors access to a central panel for customized malware builds and stolen data retrieval. The stolen information includes credentials, cryptocurrency wallets, and sensitive data, posing risks of identity theft and financial fraud. Lumma Stealer was first identified on Russian-language crime forums in early 2023 and has since migrated to Telegram for distribution. Its proliferation is facilitated by social engineering campaigns, including deceptive pop-ups and bundled malware in cracked software. Cloudflare implemented measures to block access to Lumma's command and control servers and collaborated with various authorities to prevent the criminals from regaining control. Mitigation strategies for users include restricting unknown scripts, limiting password storage in browsers, and using reputable endpoint protection tools. The operation has significantly hindered Lumma's operations and aims to undermine the infostealer-as-a-service model contributing to cybercrime.

Microsoft, in collaboration with law enforcement, has taken legal action against the Lumma malware operation, which has affected over 394,000 Windows PCs globally, particularly in Brazil, Europe, and the United States. A federal court authorized the seizure of 2,300 domains used as command and control servers for Lumma, and the Justice Department confiscated five additional domains related to its infrastructure. Lumma is primarily spread through questionable games or cracked applications and extracts sensitive information such as logins, passwords, credit card details, and cryptocurrency wallets, which is then sold to other cybercriminals. Lumma also facilitates the deployment of additional malware, including ransomware, and has been linked to significant cyberattacks on major tech companies like PowerSchool and Snowflake, resulting in substantial data theft.

A hacker breached TeleMessage, a messaging app used by members of the Trump administration and US government officials, in a quick attack that reportedly took 15 to 20 minutes. The breached materials included sensitive data related to Customs and Border Protection (CBP) and cryptocurrency exchange Coinbase. A screenshot from the control panel showed names, phone numbers, and email addresses of CBP employees, indicating access to data of hundreds of US government personnel. Michael Waltz, the recently dismissed national security adviser, was noted to have used TeleMessage during a cabinet meeting.

The Play ransomware gang exploited a critical vulnerability in the Windows Common Log File System, identified as CVE-2025-29824, to execute zero-day attacks, gaining SYSTEM privileges and deploying malware. Microsoft recognized this flaw and issued a patch during last month's Patch Tuesday. The gang targeted sectors including IT and real estate in the U.S., the financial sector in Venezuela, a Spanish software company, and retail in Saudi Arabia. They used the PipeMagic backdoor malware to deploy the CVE-2025-29824 exploit and install ransomware payloads. Symantec's Threat Hunter Team linked these activities to the Play ransomware-as-a-service operation, noting the use of the Grixba infostealer tool. The Play ransomware group, active since at least June 2022, employs double-extortion tactics and has compromised approximately 300 organizations globally as of October 2023. Notable victims include Rackspace, Arnold Clark, the City of Oakland, Dallas County, Antwerp, and Microchip Technology.

Cybercriminals are using legitimate software tools to create deceptive Android applications that steal sensitive user information. McAfee's findings indicate that hackers are exploiting the .NET MAUI framework to develop sophisticated malware that can evade traditional antivirus detection. The malware uses a multi-stage dynamic loading process, incrementally loading and decrypting code, making it difficult for security software to identify the applications' true nature. Hackers add extraneous settings and permissions to confuse security scanners and use encrypted communications for data transmission instead of standard internet requests. These malicious applications are not found in reputable app stores like Google Play but are distributed through unofficial app stores, often accessed via phishing links. Examples include a counterfeit banking app and a fraudulent social networking service targeting the Chinese-speaking community. The main goal of these apps is to secretly extract user data and send it to the attackers' servers. Users are advised to download apps only from official repositories and to be cautious by reviewing user feedback before installation.

A new variant of the Snake Keylogger is targeting Windows users in Asia and Europe, utilizing the AutoIt scripting language for deployment to evade detection. This malware, built on the Microsoft .NET framework, infiltrates systems through spam email attachments, logging keystrokes, capturing screenshots, and collecting clipboard data to steal sensitive information like usernames, passwords, and credit card details from browsers such as Chrome, Edge, and Firefox. The keylogger transmits stolen data to its command-and-control server using methods like SMTP email, Telegram bots, and HTTP POST requests. The executable file is an AutoIt-compiled binary that unpacks and executes the keylogger upon opening. The keylogger replicates itself in the %Local_AppData%supergroup directory as ageless[.]exe and places a file named ageless[.]vbs in the Startup folder to ensure it runs automatically on system reboot. This persistence mechanism allows continued access to the infected machine without requiring administrative privileges. Once activated, the keylogger injects its payload into a legitimate .NET process, specifically targeting RegSvcs.exe through process hollowing. It logs keystrokes using the SetWindowsHookEx API with a low-level keyboard hook, capturing sensitive information. Additionally, it retrieves the victim's public IP address by pinging hxxp://checkip[.]dyndns[.]org for geolocation purposes.
