TELEPUZ is a rapidly evolving modular MaaS malware delivered via ClickFix social engineering and VIDAR second-stage downloader chains. The 64-bit Windows DLL payload uses indirect syscalls, NTDLL unhooking, AMSI/ETW patching, and custom RC4 encryption for defense evasion, while establishing persistence as a Windows service and communicating over WebSockets with fallback C2 resolution via Telegram, Steam, DNS records, and Polygon blockchain smart contracts. The malware supports 36 commands including process hollowing, keylogging, credential theft, browser cookie extraction, and a WebInjector module that abuses Chrome DevTools Protocol to manipulate financial web forms in real-time.

TELEPUZ: a modular MaaS malware spreading via CLICKFIX-VIDAR chains Kratos PhaaS Targets US and EU: How to Reduce Microsoft 365 Account Takeover Risk Kratos is a mature Phishing-as-a-Service operation impersonating Microsoft 365 login pages to steal credentials across US and European organizations. The kit uses legitimate platforms (SharePoint, Canva, Tilda) as intermediary redirect pages, Cloudflare Turnstile to block automated analysis, and PHP endpoints for credential exfiltration. Researchers identified three generations (V0, V1, V2) with distinct asset fingerprints and exfiltration code, and uncovered the operator panel with automated deployment, Telegram-based data delivery, and geographic restriction capabilities.
Cavern Manticore: Exposing Iran-Linked Modular C2 Framework Cavern Manticore, an Iran-MOIS-linked APT group, deploys a modular .NET C2 framework targeting Israeli government and IT organizations. The framework uses three compilation formats (Mixed-Mode C++/CLI, NativeAOT, .NET Framework) as an anti-analysis layer, with DLL sideloading via WinDirStat.exe for initial execution. Post-exploitation modules provide DPAPI decryption, LDAP brute-forcing, SQL browsing, network reconnaissance, and SOCKS5 tunneling, with C2 traffic XOR-encrypted over HTTPS/WebSocket channels.
STOCKSTAY Another Day: The Latest Addition to Turla’s Intelligence Gathering Apparatus Google Threat Intelligence Group analyzed STOCKSTAY, a modular .NET backdoor developed and operated by Turla since late 2022, which uses a WebSocket-based C2 channel, RSA/AES encrypted communications, and IPC via WM_COPYDATA between its downloader, orchestrator, tunneler, and backdoor components. STOCKSTAY exhibits strong code, architectural, and obfuscation (K1MORPHER) overlaps with KAZUAR, suggesting a shared development team, and has been deployed via phishing (malicious RDP files, HTA lures) and, most recently, exploitation of CVE-2025-8088 in WinRAR to target Ukrainian military personnel. The actor leverages legitimate hosting platforms (Render, Glitch, GitHub) and compromised third-party/government infrastructure to obscure C2 infrastructure and complicate attribution.
Vibe Hacking: Two AI-Augmented Campaigns Target Government and Financial Sectors in Latin America Trend Micro identified two distinct threat campaigns, SHADOW-AETHER-040 and SHADOW-AETHER-064, leveraging agentic AI to orchestrate attacks against Latin American government and financial institutions. The attackers utilized AI models like Anthropic's Claude to dynamically generate scripts, analyze configurations, and establish SOCKS5 tunnels for lateral movement, demonstrating a shift towards AI-assisted, signature-evasive intrusion operations.
Snow Flurries: How UNC6692 Employed Social Engineering to Deploy a Custom Malware Suite Google Threat Intelligence Group identified UNC6692, a threat actor utilizing Microsoft Teams phishing and email bombing to deploy a custom modular malware suite. The attack chain leverages a malicious Chromium extension (SNOWBELT), a Python tunneler (SNOWGLAZE), and a Python bindshell (SNOWBASIN) to establish persistence, move laterally, and exfiltrate sensitive Active Directory data via legitimate cloud services.
Active Magecart Campaign Targets Spain, Steals Card Data via Hijacked eStores for Bank Fraud A sophisticated, long-running Magecart campaign has been compromising e-commerce websites to steal payment card data, with a notable focus on the Spanish payment ecosystem. The attackers utilize multi-stage JavaScript payloads, mimic legitimate payment gateways like Redsys, and exfiltrate stolen data in real-time via WebSockets to evade traditional detection mechanisms.
Google Authenticator: The Hidden Mechanisms of Passwordless Authentication This architectural analysis details the hidden mechanisms behind Google's synced passkeys, revealing a hybrid model that leverages a cloud-based authenticator (enclave.ua5v[.]com) for sensitive cryptographic operations while anchoring trust to local hardware keys. Understanding this infrastructure is critical for defenders to anticipate emerging attack vectors in passwordless authentication environments.
