An Iranian state-aligned threat actor, CL-STA-1178, has been conducting the Blinder Tunnel campaign since November 2025, targeting Iraqi critical infrastructure by impersonating the Dubai Airports IT department. The campaign delivers trojanized coding challenges that deploy ShelbyLoader V2 malware through a multi-stage attack chain involving AppDomainManager hijacking and DLL sideloading. The attackers use GitHub API infrastructure for command-and-control communications, including repositories and issues as fallback channels. Operational security errors revealed links to a separate credential harvesting campaign targeting Israeli entities with conflict-themed Google Drive lures in mid-2026.

SectopRAT (also known as ArechClient2) is a .NET-based remote access trojan (RAT) that provides a range of functions through multiple control commands. These include collecting sensitive data from the victim’s device, capturing screens, remotely managing processes and files, controlling bots, and other forms of remote device management.

A Windows malware called CLOSEDQUORUM is built to take orders from a vote of up to four AI models instead of an attacker's server, Cisco Talos said on September 22. The models can choose to steal Windows credentials, saved browser passwords, and crypto wallet data. Talos has not seen this setup work from start to finish, and the public version of the malware does not work as it is.

A third variant of PamStealer has been identified, distributed through a fake Wavel cryptocurrency wallet application. The malware employs a sophisticated server-side decryption chain using a purpose-built utility called pkgunpack that performs live ECIES key exchange with command-and-control infrastructure, making offline payload decryption impossible. The second stage has been rewritten from Rust to Swift while maintaining PAM-based credential validation. The infostealer targets seventeen browsers including Arc, Zen, Waterfox, and LibreWolf, extracts keychain credentials, collects system fingerprints, and harvests user files including shell history and account photos via Open Directory. Persistence is maintained through four redundant repair mechanisms including LaunchAgent installation, shell hooks, Git hooks, and a local backup tarball, with notification suppression achieved by killing background task management processes.

LabubaRAT is a custom 64-bit Rust-based remote access trojan targeting Windows systems, masquerading as legitimate NVIDIA software. It offers extensive remote control features such as command execution, file operations, screen capture, and SOCKS5 proxying. The malware is part of a malware-as-a-service framework, managed via a backend called LabubaPanel hosted on German infrastructure. It uses its own JavaScript execution for delivery and employs evasion techniques including impersonation of NVIDIA components and abuse of Microsoft build utilities. First observed in July 2026, it is unsigned and designed for persistence and stealth.

Noodle RAT, also known as ANGRYREBEL or Nood RAT, is a modular remote access trojan with dual versions for Windows and Linux, actively used by Chinese-speaking threat actors since at least mid-2016. Previously misclassified as variants of Gh0st RAT or Rekoobe, it is now recognized as a distinct backdoor family. The malware has been deployed in espionage and cybercrime campaigns targeting entities across the Asia-Pacific region, including Thailand, India, Japan, Malaysia, and Taiwan. Multiple threat groups including Iron Tiger, Calypso APT, Rocke, and Cloud Snooper have utilized this tool. Both variants feature shared command-and-control architecture, similar configuration structures, and modular capabilities. The Windows version operates as an in-memory backdoor with file management and proxy capabilities, while the Linux variant provides reverse shell, SOCKS tunneling, and task scheduling functionalities. Evidence suggests an actively maintained, possibly commercial malware toolkit.

An intrusion was investigated that began with exploitation of CVE-2026-48558, a critical authentication bypass vulnerability in SimpleHelp RMM software. The threat actor obtained unauthorized technician access and deployed two previously undocumented malware samples: TaskWeaver and Djinn Stealer. TaskWeaver is a heavily obfuscated Node.js loader that establishes encrypted communications and delivers additional payloads. Djinn Stealer targets credentials across Windows, macOS, and Linux systems, collecting authentication data for cloud platforms, source control, package registries, AI development assistants, browsers, SSH keys, and cryptocurrency wallets. The attacker leveraged legitimate RMM capabilities to transfer files and execute commands across managed systems. Stolen AI assistant tokens provided extensive access to repositories, databases, and cloud accounts. The intrusion demonstrated how a single authentication bypass in trusted management infrastructure can enable widespread credential theft and p...

A previously undocumented Linux toolkit has been targeting South Korean automotive and media organizations with minimal detection since early 2025. The campaign employs a HAProxy instance called ted backdoor, compiled within the victim's existing HAProxy version 2.8.12, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This sophisticated framework enables remote command execution, malicious script injection into web traffic, credential harvesting, and long-term surveillance. The ted backdoor uses HAProxy's native filter API and internal structures to intercept SSL-decrypted HTTP traffic while maintaining legitimate load balancing operations. Operating alongside are an SSH keylogger, a curl-based RAT with HAProxy health monitoring capabilities, and a deployment stager. The toolkit is attributed with medium confidence to DPRK APTs based on targeting patterns, simple XOR-based encryption schemes, custom substitution ciphers, and C2 infrastructure associated with APT37.
