Detects Gootloader's persistence mechanism where a shortcut (.lnk) file is placed in the Startup folder or AppData, which in turn executes a JavaScript file using an 8.3 short filename.
Detects the execution of PowerShell commands associated with the ClickFix social engineering tactic. This involves downloading and executing remote payloads, often followed by creating a .lnk file in the Startup folder for persistence.
Detects network connections to Command and Control (C2) servers associated with the LANDFALL Android spyware. LANDFALL communicates over HTTPS, often on non-standard ports.
Detects post-exploitation behavior of LANDFALL spyware on Samsung devices. After exploiting CVE-2025-21042, the spyware uses LD_PRELOAD to inject a malicious shared object (.so) from its working directory (`/data/data/com.samsung.ipservice/files/`) into the benign `/system/bin/id` process, often via a shell wrapper.
Detects the creation of potential LANDFALL spyware delivery files. These are malformed DNG image files, often with filenames suggesting delivery via WhatsApp, used to exploit CVE-2025-21042.
Detects the execution of the LANDFALL spyware's SELinux policy manipulation helper (`l.so`). The spyware's loader (`b.so`) sets a `PRELOAD_PATH` environment variable pointing to `l.so` and uses `LD_PRELOAD` to inject another payload into the benign `/system/bin/id` process. This behavior is specific to the "interactive" execution mode of the spyware.
Detects post-exploitation behavior of LANDFALL spyware on Samsung devices. After exploiting CVE-2025-21042, the spyware uses LD_PRELOAD to inject a malicious shared object (.so) from its working directory (`/data/data/com.samsung.ipservice/files/`) into the benign `/system/bin/id` process, often via a shell wrapper.
Detects access or search activity in SharePoint or OneDrive involving keywords related to gift cards, IT workflows, and remote access. This is a reconnaissance technique used by the Jingle Thief group (also tracked as Atlas Lion and STORM-0539) to find sensitive internal documentation.
Detects URLs that use the `https://user@host` syntax where the 'user' part is crafted to look like a legitimate domain (e.g., `https://example.com@malicious-site.net`). This is a technique used by the Jingle Thief group (also tracked as Atlas Lion and STORM-0539) to craft convincing phishing links.
Detects the registration of a new device or MFA authentication method in Microsoft Entra ID from an IP address geolocated to Morocco. This is a persistence tactic used by the Jingle Thief group (also tracked as Atlas Lion and STORM-0539).
