Fraudulent organizations in Korea are exploiting private Home Trading System (HTS) software to distribute ransomware to victims. The unauthorized HTS program called 'UBP Asset' impersonates the legitimate Swiss financial institution Union Bancaire Privee (UBP) and has been used in investment scams since at least September 2025. Attackers lure victims through social media platforms like Telegram and KakaoTalk, convincing them to install the fraudulent HTS and deposit funds. The latest campaign involves distributing KRSID ransomware through the HTS update mechanism, which encrypts files using AES-256 and RSA-2048 algorithms. Previous campaigns used similar private HTS programs to distribute Quasar RAT. Victims not only lose their investment funds but also have their systems compromised and files encrypted for ransom demands.

Mythic is an open-source collaborative command-and-control framework with plugin-based architecture supporting multiple agent types and transport profiles. It features a web-based operator interface used by red teams for authorized engagements, though threat actors have also deployed it in unauthorized intrusions. Analysis identifies 131 unique hosts exposing Mythic on the public Internet, with 115 carrying default certificate configurations. The infrastructure spans predominantly DigitalOcean, AWS, and Azure environments, concentrated in the United States, Hong Kong, and China. Default deployment artifacts including TLS certificates with O=Mythic subjects, port 7443 responses, and internal PKI chains enable detection. Multi-framework clusters suggest training environments, while isolated deployments with custom domains and staged payloads indicate operational use with Discord-based transports and steganographic techniques.

The GrelosGTM cybercriminal group abuses the legitimate functionality of Google Tag Manager to compromise e-commerce websites, primarily those running Magento CMS. Since early 2020, they have injected malicious Google Tag Manager scripts that load multi-stage JavaScript payloads via WebSocket connections. The final payload is a heavily obfuscated JavaScript sniffer designed to steal payment card information during checkout through fake payment forms. Stolen data is exfiltrated to attacker-controlled servers. The campaign has affected at least seven websites across Belgium, Italy, the United Kingdom, and the United States.

Two sophisticated phishing campaigns employed browser-in-the-browser (BiTB) techniques to deceive victims into installing rogue ScreenConnect remote management tools. Attackers sent phishing messages with malicious links redirecting targets to fake Adobe Reader update pages. The BiTB technique created convincing fake browser windows within webpages, displaying legitimate-looking Adobe URLs to bypass user awareness training. Victims were tricked into downloading ScreenConnect installers disguised as Adobe software updates. Each incident resulted in deployment of multiple rogue ScreenConnect instances for redundant persistence, followed by execution of defense-evasion binaries (HideCursor.exe and HideUL.exe) designed to hide attacker activities. The attacks established service-based persistence through Windows services, enabling continued remote access. Both campaigns were intercepted before further damage occurred, demonstrating how threat actors combine social engineering throughout the entire attack chain...

Socket identified a coordinated campaign involving 77 Firefox extensions designed to steal cryptocurrency wallet secrets and credentials. The operation, tracked as 'Offside Wallet Theft Factory', includes 40 confirmed malicious extensions that exfiltrate recovery phrases, private keys, and credentials through Supabase-controlled remote switches, Cloudflare Workers, and hardcoded command-and-control infrastructure. An additional 37 deceptive sports-score shells share publishing artifacts and version histories showing transitions from benign utilities into wallet-stealing malware. The campaign operated from at least March 2026 through August 2026, targeting Web3 users through impersonations of OKX, Rabby Wallet, TronLink, and other cryptocurrency products. Extensions capture secrets through phishing interfaces, modified wallet code, and direct credential theft, enabling immediate cryptocurrency theft and financial harm.

A new ClickFix campaign targets Windows users with a NodeJS-based infostealer delivered via malicious MSI installers. This highly adaptable remote access Trojan minimizes forensic footprints through dynamic capability loading, with core stealing modules and communication protocols delivered in-memory only after C2 connection. The malware routes gRPC streaming traffic over Tor network for persistent, masked bidirectional channels. An operational security failure exposed server-side admin panel protocol definitions, revealing a malware-as-a-service backend designed to manage multiple operators and automate cryptocurrency asset tracking. The modular architecture delivers malicious logic dynamically as strings executed in-memory, bypassing static signature detection while supporting full RAT functionality including shell command execution and wallet tracking.

In May 2026, a cyber-espionage campaign by the Armored Likho group (also known as Eagle Werewolf) targeted private individuals and organizations across Russia, including major corporations, public sector entities, IT companies, and educational institutions. The attackers employed fake donation service applications as initial infection vectors. The campaign introduced the Still Toolkit, comprising two Rust-based components: Still Sync, which steals Telegram session data and leverages the Telegram API to extract chat logs and media files, and Still Audio, an implant that conducts covert audio surveillance by detecting speech patterns and recording conversations. The toolkit demonstrates sophisticated capabilities including Dead Drop Resolver techniques, RMS-based voice activity detection, and gRPC-based C2 communications. The campaign shows significant code overlap with previous Armored Likho operations, particularly from February 2026, including identical dropper architecture, encryption algorithms, and inf...

Jewelbug is a China-based threat actor conducting dual operations: espionage campaigns targeting foreign governments and militaries, alongside a for-profit cryptocurrency fraud business administered from the same control panel. Operating as a small development team with role-based access controls and documented roadmaps, the group recorded over one million implant check-ins, 580,000+ stolen browser cookies, and 2,300+ exfiltrated emails between February and May 2026. Espionage attacks targeted government entities in the Middle East, Southeast Asia, and South Asia with confirmed intrusions. The group deploys the Antino backdoor, a malicious Chrome/Firefox extension called 'PDF Viewer,' and a Linux implant named ClientKing targeting servers and routers. The financially motivated arm operates as a registered Hunan company running industrial-scale SEO poisoning funneling Chinese-speaking victims to fake cryptocurrency exchange sites.

An investigation uncovered a sophisticated infection chain beginning with a ClickFix lure and utilizing a legitimately signed IBM SPSS IDE alongside four decoy DLLs and a date-formatting API as a trampoline. This chain deploys BabaDeda loader stage that ultimately delivers CNCMachineRMS, a 1.14 MB x64 remote administration implant with no imports and runtime-built strings. The implant provides operators with comprehensive remote access capabilities including an interactive shell, file manager, screen capture, local account backdoor, and seven persistence mechanisms. It employs a custom scripting language and uses the same binary container format for configuration and C2 traffic. The implant beacons every 600 seconds, creates privileged local accounts, and supports twenty typed commands for downloading and executing additional payloads, indicating hands-on-keyboard access with follow-on stages determining actual damage.

Security researchers have uncovered a sophisticated cyber espionage operation deploying two previously undocumented malware families, OctLurk and SilkLurk, targeting government and public-sector organizations across Central Asia and the Middle East. Both modular backdoors utilize victim-specific decryption mechanisms, extensive obfuscation, and in-memory execution to evade detection. The malware enables credential theft, remote access, network reconnaissance, and plugin-based expansion. Operations began in January 2025, affecting entities in Afghanistan, Kazakhstan, Kyrgyzstan, Syria, Tajikistan, and Uzbekistan. Victims include government offices, foreign affairs ministries, law enforcement agencies, healthcare providers, logistics organizations, research institutions, urban planning facilities, and educational establishments. Attackers deployed additional tools including Impacket's SecretsDump, Browser Password Decryptor, Pandora RC, Fscan, WinRAR, 7-Zip, and PlugX. A companion utility, LurkProxy, proxies a
