A multinational law enforcement operation called Operation Endgame has successfully disrupted SocGholish, a malware framework operated by threat actor TA569 since 2017. The operation took down 106 servers and domains and remediated nearly 15,000 compromised WordPress websites. SocGholish uses fake browser update prompts on compromised websites to trick victims into downloading malicious JScript payloads, providing initial access to corporate networks for ransomware deployment and data breaches. Analysis revealed that 55% of Infoblox cloud customers were exposed to SocGholish in 2026, demonstrating widespread impact across multiple industries including government, education, and healthcare. The framework employs domain shadowing techniques and operates through a four-stage attack chain involving traffic acquisition, filtering, fake update lures, and on-device implant execution. SocGholish infrastructure has facilitated access for various ransomware families and has been extensively used by the notorious Evi...

A cybercrime campaign active since at least 2022 has been distributing cryptocurrency miners and RAT malware through illegal streaming sites and digital libraries. Victims are tricked via fake video player plugin updates or browser crash pages into downloading ZIP archives containing legitimate executables and malicious DLLs. The malware employs DLL side-loading, establishes persistence through Windows services, and deploys multiple components including XMRig-based CPU miners, GPU miners, a watchdog module, and a RAT agent with remote control capabilities. The campaign leverages highly popular pirated content sites with monthly traffic reaching up to 40 million visits, significantly expanding the potential victim pool. The malware includes sophisticated anti-detection features, DNS tunneling for command-and-control, and domain generation algorithms based on dates.

A malicious campaign is targeting indie game platforms Itch.io and Patreon by posting fake update links in comments, which lead to downloads of LummaStealer malware. This malware uses advanced anti-analysis techniques to evade detection, including checks for virtual machines, specific usernames, and malware analysis processes. The payload is delivered via a nexe-compiled JavaScript file that drops and loads a DLL variant of LummaStealer. Despite efforts to remove malicious accounts, attackers continuously create new ones, indicating an ongoing and persistent threat. The campaign primarily targets users seeking game updates, exploiting trust in indie game communities. No known exploits in the wild have been reported yet, but the malware’s stealth and persistence pose a medium-level risk. European organizations involved in gaming, digital content creation, or using these platforms could be impacted, especially those with less mature security controls. Mitigation requires targeted detection of fake update links, monitoring of platform comments, and enhanced endpoint defenses against DLL injection and obfuscated JavaScript. Countries with active indie game development and strong Patreon/Itch.

Insikt Group uncovered new infrastructure linked to GrayAlpha, a threat actor associated with FIN7. They identified a custom PowerShell loader named PowerNet that deploys NetSupport RAT, and another loader called MaskBat. Three main infection vectors were discovered: fake browser updates, fake 7-Zip download sites, and the TAG-124 traffic distribution system. While all three methods were used simultaneously, only the fake 7-Zip sites remained active at the time of writing. The analysis also led to the identification of a potential individual involved in GrayAlpha operations. The group's sophisticated tactics highlight the need for comprehensive security measures, including application allow-listing, employee training, and advanced detection techniques.
