A misconfigured Python HTTP server on a Budapest VPS exposed the complete operational infrastructure of three distinct phishing operators. The investigation uncovered codemado, an Egyptian threat actor operating since 2018, running a full AiTM platform with custom tools including MaDoO Blaster; saroula01, deploying OAuth Device Code Flow attacks that accumulated 218 victims across 12 countries over a year; and mail-argenta, a Nigerian operator identified through infostealer logs containing his own credentials. All three actors leveraged customized Evilginx forks and AI-assisted development to build MFA-bypass infrastructure from public GitHub repositories. The campaigns targeted Microsoft 365 accounts primarily, with codemado maintaining ties to RockyBelling's "The Quarry" cybercrime ecosystem. The exposed server contained phishing configurations, credential logs, RMM installers, combolists, and Telegram session files, revealing sustained operations from at least January 2025 through May 2026.
The threat actor uses modular RATs and information stealers in financially motivated and cyber espionage campaigns. The post Armored Likho APT Targeting Government, Electric Power Entities appeared first on SecurityWeek .
Beginning in August 2025, a sophisticated intrusion was discovered where attackers used log poisoning techniques to deploy a web shell on vulnerable phpMyAdmin panels. The threat actors exploited misconfigured web applications to plant China Chopper web shells, controlled via AntSword, before deploying Nezha, an open-source monitoring tool, to facilitate remote command execution. This led to the deployment of Ghost RAT on compromised systems. Analysis revealed over 100 compromised machines, predominantly located in Taiwan, Japan, South Korea, and Hong Kong. The attackers demonstrated technical proficiency through multi-stage operations, utilizing AWS and VPS infrastructure, with indicators pointing to China-nexus threat actors. The campaign highlights increasing abuse of legitimate publicly available tools to achieve malicious objectives while maintaining plausible deniability.
Kaspersky uncovered a sophisticated phishing campaign by the APT group Armored Likho, deploying a previously undocumented Python-based infostealer dubbed BusySnake Stealer. The campaign targets government agencies and electric power sectors across Russia, Brazil, and Kazakhstan through spear-phishing emails containing malicious EXE or LNK attachments. BusySnake Stealer features advanced obfuscation using PyArmor Pro, extracts credentials from browsers using DPAPI and NSS libraries, captures screenshots, logs keystrokes, scrapes cryptocurrency wallets and 2FA tokens, and establishes reverse SSH tunnels for remote access. The threat actor leverages AI-generated code for first-stage payloads and distributes components via GitHub repositories. The stealer maintains persistence through scheduled tasks and communicates with C2 infrastructure to receive commands dynamically, representing a significant evolution in the group's technical capabilities.
