A comprehensive analysis of 339 commands issued by a French-speaking threat actor nicknamed 'Poisson' over 33 days, targeting a French automotive small business and four French individuals. The attacker utilized a multi-stage fileless attack deploying a 70-line Python keylogger to harvest banking and email credentials. The operation leveraged free-tier infrastructure including Havoc C2 framework, Backblaze B2 storage, and DuckDNS. Most significantly, the attacker installed OpenSSH and Tailscale VPN on victim machines, creating persistent access that survived C2 server takedown. When the C2 went offline for 18 days, the attacker's access remained intact through the VPN mesh, demonstrating that VPN-mesh-based persistence is actively used in real-world intrusions and that traditional C2 takedown is insufficient for remediation.

A sophisticated cyber attack campaign combines social engineering and advanced malware techniques. Attackers pose as IT support to gain initial access, then deploy a modified version of the Havoc C2 framework. The malware uses DLL sideloading, indirect syscalls, and custom loaders to evade detection. After compromising the initial system, the attackers rapidly move laterally, establishing persistence through scheduled tasks and legitimate remote monitoring tools. The campaign demonstrates a blend of human-centric initial access methods and advanced technical evasion techniques, highlighting the need for comprehensive security measures spanning user awareness and technical controls.

An extensive cyber espionage campaign conducted by SloppyLemming, an India-nexus threat actor, targeted government entities and critical infrastructure in Pakistan and Bangladesh from January 2025 to January 2026. The campaign used two attack vectors: PDF lures with ClickOnce execution chains and macro-enabled Excel documents. It deployed a custom x64 shellcode implant named BurrowShell and a Rust-based keylogger. The attackers extensively abused Cloudflare Workers for C2 and payload delivery, registering 112 domains impersonating government entities. The campaign focused on nuclear, defense, telecommunications, energy, and financial sectors, aligning with regional strategic competition in South Asia.

Kaspersky researchers uncovered new malicious operations by the Tomiris threat actor targeting foreign ministries, intergovernmental organizations, and government entities. The attacks, which began in early 2025, show a shift in tactics with increased use of implants leveraging public services like Telegram and Discord as command-and-control servers. The group employs various programming languages including Go, Rust, C/C#/C++, and Python to develop reverse shell tools. Some infections lead to the deployment of open-source post-exploitation frameworks such as Havoc and AdaptixC2. The campaign primarily focuses on Russian-speaking users and entities, with additional targets in Central Asian countries.
