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.

ToddyCat APT developed a tool called Umbrij that automates the theft of Google OAuth authorization codes by launching Chromium-based browsers in headless mode with remote debugging ports enabled. The tool copies the victim's browser profile to a backup directory, launches the browser invisibly with the stolen session, and uses Puppeteer Sharp to automate the Google OAuth consent flow using legitimate Google Workspace Migration/Sync client IDs. The resulting authorization code is exfiltrated and exchanged for an access token, enabling API-level access to the victim's Gmail, Drive, Calendar, and Contacts without traditional credential theft.
