Two previously undocumented .NET malware components were delivered through a ClickFix infection chain. RemotePanel establishes persistent remote access by masquerading as the Windows Time service, providing operators with PowerShell control, file and process management, screen access, modular HVNC, and fleet management capabilities. It uses a BNB Smart Chain contract to dynamically resolve its active Command and Control server, enabling infrastructure rotation without rebuilding the RAT. BoundSiphon runs primarily from memory, targeting browser credentials and sessions, cryptocurrency wallets, password manager data, and documents, including secrets protected by Chromium App-Bound Encryption. Strong code overlap exists between BoundSiphon and a stealer previously documented by Socket, linking the sample to an earlier stealer codebase. The modular design separates persistent access from data theft, allowing operators to replace infrastructure and individual components while maintaining operational capabilities.

On 5 May 2026, a Jamf Protect deployment blocked a download attempt from jacksonvillemma[.]com, four days after the operator's previous MacSync C2 was publicly disclosed. The new C2's TLS certificate was issued within 24 hours of that disclosure. Analysis revealed a Stage 2 zsh loader containing a static api-key value observed across four distinct C2 domains spanning December 2025 to May 2026. URI-pattern pivoting through any.run identified eleven additional candidate C2 domains dating back to February 2026, suggesting parallel infrastructure operation rather than sequential rotation. The loader exfiltrates macOS credentials, browser data, and cryptocurrency wallets, and transmits the victim's account password in cleartext via URL query strings, making it visible in web proxy logs.

OnyxC2 emerged in early 2026 as a malware-as-a-service stealer sold on cybercrime networks for $250 monthly. The platform includes a web panel, payload builder, and tiered pricing structure with refund guarantees. Written in C++ with assembly for direct syscalls, it targets approximately 210 applications across nine categories: 45 browsers, 109 extensions including 2FA tools, 5 password managers, 17 cryptocurrency wallets, 11 FTP clients, 5 email clients, and VPN/messaging applications. The stealer achieves 99% detection evasion through mutated builds and delivers via DLL sideloading using signed binaries. Higher tiers unlock remote access capabilities including HVNC, LSASS dumping, reverse SOCKS5 proxy, keylogging, and reverse shell. Distribution occurs through fake installers delivered as password-protected archives, with C2 communication over Cloudflare-fronted HTTPS to akmuniverstall.top.

SilabRAT is an advanced Remote Access Trojan offered as Malware-as-a-Service on Darkweb forums since late 2025, developed by threat actor o1oo1 and sold for $5,000 monthly. This financially-motivated tool focuses on credential theft and cryptocurrency operations, featuring Hidden Virtual Network Computing for invisible remote control, browser profile cloning to bypass session protections, and automated cryptocurrency wallet password cracking. The RAT bypasses Chrome App-Bound Encryption, performs session hijacking, and includes keylogging, clipboard monitoring, and remote desktop capabilities. Distributed through phishing and ClickFix campaigns with operator-hosted infrastructure, SilabRAT uses ChaCha20-Poly1305 encryption for command-and-control communications. The developer also offers AsmCrypt, a companion crypter service, creating a complete malware bundle from evasion to execution and remote control.

MacSync Stealer is a macOS infostealer operating as Malware-as-a-Service (MaaS), distributed through SEO poisoning and fake ClickFix CAPTCHAs. The campaign has evolved through three iterations since November 2025, shifting from fake download sites to malicious ChatGPT conversations and finally to sophisticated shell-based loaders with dynamic AppleScript payloads. Threat actors use Google-sponsored search results to redirect victims to fake CAPTCHA pages that trick users into executing malicious terminal commands. The stealer targets browser credentials, cryptocurrency wallets, SSH keys, cloud provider credentials, and Keychain data. A critical capability includes trojanizing Ledger hardware wallet applications to capture seed phrases. The February 2026 campaign generated over 18,000 clicks in three days, with Russian-language comments suggesting operators work within a Russian-speaking ecosystem. The malware employs API key-gated C2 infrastructure and in-memory execution for evasion.

A North Korean threat operation has published malicious packages across npm, PyPI, Go Modules, crates.io, and Packagist, impersonating legitimate developer tooling. The campaign uses GitHub aliases including golangorg and aokisasakidev to distribute staged malware loaders that contact actor-controlled infrastructure, retrieve payloads from Google Drive, and deliver platform-specific second-stage malware. The loaders are hidden behind normal-looking API functions in logging and utility libraries. Windows variants include full remote access trojans with capabilities for shell execution, keylogging, browser and wallet theft, sensitive file collection, and AnyDesk deployment. The operation demonstrates coordinated cross-ecosystem supply chain attacks with shared infrastructure patterns, reused extraction directories, and consistent staging logic across multiple programming languages.

Marco Stealer, discovered in June 2025, is an information stealer targeting browser data, cryptocurrency wallets, and sensitive files. It employs anti-analysis techniques, string encryption, and terminates security tools. The malware collects system information, exfiltrates browser data using embedded files, and extracts cryptocurrency wallet data from browser extensions. It also targets popular services and cloud storage. Marco Stealer uses AES-256 encryption for C2 communication over HTTP. Despite recent law enforcement actions against similar threats, information stealers continue to pose significant risks to corporate environments.
