Infection vectors likely include unofficial app stores, malicious APKs, and phishing links, with no evidence of distribution via Google Play. Manic abuses Accessibility permissions to spy on users, grant itself additional permissions, and prevent removal. It overlays an invisible keyboard to capture passwords and sensitive input. The malware has been active since at least May 2026 and continues to evolve to evade detection.
A newly identified Android malware family named Manic combines banking malware and mobile spyware capabilities, targeting Ukrainian banks, government services, messaging applications, Russian and European financial institutions, and global fintech and cryptocurrency services. Active since February 2026, Manic enables extensive Device Takeover operations through sophisticated surveillance and remote-control features. It employs advanced PIN stealing techniques without requiring traditional overlay attacks, utilizing Accessibility services as a UI keylogger to capture lock-screen inputs, recovery phrases, and authentication codes. A distinctive feature is its Wi-Fi mesh egress technique, allowing compromised devices to relay stolen data through other infected phones via Wi-Fi Direct, Bluetooth, or BLE when direct C2 access is unavailable. The malware monitors 169 applications including banks, cryptocurrency wallets, government eID services, and military-focused messengers across multiple countries.
Kratos is a mature Phishing-as-a-Service operation targeting Microsoft 365 users across the United States, Europe, and other regions. The platform enables attackers to steal credentials through trusted platforms, anti-bot verification, and convincing login pages. Researchers traced three generations of the kit and uncovered 1,484 previously unattributed detonations. The operation targets organizations across more than 20 countries with particularly strong concentration in the US, Spain, and Southern Europe. Kratos includes an operator panel allowing deployment of phishing domains, configurable Telegram or email delivery, geographic restrictions, and multiple anti-bot systems. The kit has evolved through three page generations (V0, V1, V2) with different exfiltration code. Activity has been visible since January 2026, with the operator panel active since September 2025.
A new variant of the TrickMo Android banking trojan was identified between January and February 2026, representing a substantial platform redesign rather than new capabilities. The malware has migrated its command-and-control infrastructure entirely onto The Open Network (TON) using .adnl endpoints, moving away from conventional internet infrastructure. Active campaigns have targeted banking and wallet users in France, Italy, and Austria. Once accessibility permissions are granted, operators gain real-time device control including credential phishing, keylogging, screen recording, SMS interception, and bidirectional remote control. New features include network reconnaissance capabilities and SSH tunnelling that transform infected devices into programmable network pivots and SOCKS5 proxy exit nodes, enabling operators to bypass IP-based fraud detection systems while accessing victim networks.

This analysis details how threat actors are exploiting Windows File Explorer's WebDAV functionality to deliver malware. WebDAV, a legacy protocol, is being used to trick users into downloading malicious files without going through web browsers, potentially bypassing security controls. Campaigns often use complex chains of scripts and legitimate files to deliver Remote Access Trojans (RATs). The tactic has been observed since February 2024, with increased activity from September 2024. Threat actors frequently abuse Cloudflare Tunnel demo accounts to host WebDAV servers. The report explains WebDAV links, how File Explorer can be manipulated, and various methods used by attackers, including URL shortcut files and LNK files. It also highlights the prevalence of German and English language campaigns targeting European corporate email accounts.

A convincing lookalike of the popular 7-Zip archiver site has been serving a trojanized installer that silently converts victims' machines into residential proxy nodes. The fake site, 7zip[.]com, distributes a functional copy of 7-Zip alongside concealed malware. The malware deploys three components: Uphero.exe (service manager), hero.exe (proxy payload), and hero.dll (supporting library). It establishes persistence through Windows services, manipulates firewall rules, and profiles the host system. The primary function is to enroll infected hosts as residential proxy nodes, allowing third parties to route traffic through victims' IP addresses. This campaign appears to be part of a broader operation with similar tactics used for other fake installers. The malware incorporates multiple evasion techniques and uses encrypted communications.
