Infostealers remain among the most pervasive cybercrime threats, silently harvesting passwords, cookies, and session tokens that enable enterprise breaches. StealC is a malware-as-a-service infostealer written in C++ that collects credentials from browsers, cryptocurrency wallets, messaging applications, email clients, and gaming platforms while functioning as a secondary loader. Amadey operates as a modular backdoor loader active since 2018, delivering downstream payloads including StealC, Lumma Stealer, and ransomware through various backdoor commands. Both operate on commodity rental models where stolen credentials flow through underground markets to access brokers who resell enterprise access. On June 24, 2026, Microsoft's Digital Crimes Unit coordinated with Europol to disrupt over 200 malicious command-and-control domains supporting these operations, using AI-assisted analysis tools including Microsoft Copilot for binary analysis and configuration extraction.

A large-scale malware campaign tracked as TroyDen's Lure Factory has been identified distributing LuaJIT-based infostealers through over 300 delivery packages hosted on GitHub. The operation uses AI-generated lure names incorporating obscure biological taxonomy and medical terminology to target developers, gamers, Roblox players, and crypto users. The malware employs a two-component design with a renamed LuaJIT runtime and encrypted Lua payload that evades sandbox detection through anti-analysis checks and extreme sleep delays. Upon execution, it disables proxy detection, captures desktop screenshots, performs geolocation, and exfiltrates data to C2 servers in Frankfurt. The infrastructure demonstrates scalability with multiple IP addresses serving identical encrypted commands, while maintaining simultaneous campaigns across gaming cheats, developer tools, phone trackers, and VPN crackers.

Check Point Research identified a sophisticated malware distribution campaign on YouTube called the YouTube Ghost Network. This network uses over 3,000 malicious videos to spread infostealer malware, primarily Lumma and Rhadamanthys, targeting users seeking game cheats and pirated software. The operation involves compromised YouTube accounts assigned roles such as video uploaders, community posters, and interaction simulators. Active since 2021, the campaign saw a significant rise in activity in 2025. It employs evasion techniques including password-protected archives and frequent updates to malware payloads and command-and-control infrastructure. The campaign highlights evolving malware distribution tactics on popular platforms.

A massive distribution of SmartLoader malware has been discovered through GitHub repositories masquerading as legitimate projects. These repositories focus on topics like game cheats, software cracks, and automation tools to attract users. The malware is distributed via compressed files containing a legitimate Lua loader executable, a malicious batch file, and an obfuscated Lua script. Once executed, SmartLoader establishes persistence, sends system information to a C2 server, and downloads additional payloads. The malware has been observed downloading InfoStealer malware such as Rhadamanthys, Redline, and Lumma Stealer. Users are advised to download software only from official sources and to carefully verify the credibility of GitHub repositories before use.

CastleLoader, a versatile malware loader, has infected 469 devices since May 2025 using Cloudflare-themed ClickFix phishing and fake GitHub repositories. It delivers information stealers and RATs, with a 28.7% infection rate. The malware employs sophisticated techniques, including PowerShell and AutoIT scripts, to load shellcode into memory and connect to C2 servers. CastleLoader's modular design allows deployment of multiple payloads, including StealC, RedLine, NetSupport RAT, DeerStealer, HijackLoader, and SectopRAT. Its campaigns target U.S.government entities and use legitimate file-sharing services and compromised websites for payload retrieval, enhancing resilience against takedowns.

A Malware-as-a-Service operation utilizing Amadey for payload delivery has been identified, with connections to a SmokeLoader phishing campaign targeting Ukrainian entities. The operation exploits fake GitHub accounts to host payloads and tools, bypassing web filtering. Emmenhtal, a multistage downloader, is used to download Amadey and other malware. The activity involves various malware families and GitHub repositories for staging custom payloads. Similarities in tactics and indicators between the SmokeLoader campaign and Amadey MaaS activity have been observed. The operation demonstrates adaptability in delivering diverse tooling, including legitimate software like PuTTY. The threat actors employ sophisticated obfuscation techniques and leverage public platforms for malware distribution.

A coordinated action led by Microsoft's Digital Crimes Unit, with participation from Bitsight and other partners, has successfully dismantled the operational capabilities of Lumma Stealer (LummaC2), a prominent information stealer operating since late 2022. The operation involved seizing over 1,000 domains and shutting down more than 90 Telegram channels and Steam profiles associated with the malware's infrastructure. LummaC2, which gained popularity after the takedown of Redline and Meta stealers, targeted Windows systems to extract sensitive data from various applications. The malware employed a complex, multi-tiered command and control infrastructure, using multiple domains, Steam profiles, and Telegram channels for resilience. This disruptive action is expected to significantly impact the threat landscape and hinder criminal activities in the malware scene.
