Detects PE executables whose embedded filename strings claim to be Adobe, TrueConf, or 1C software but whose PE metadata (company/product name) or digital signature does not match the claimed vendor, as used by NightEagle/GhostContainer operators to blend malicious tooling into normal process activity

This rule monitors for network connections to known command-and-control (C2) IP addresses and the execution or presence of files matching known hashes associated with the 'PhantomC2' threat group or malware family. It correlates data from DeviceNetworkEvents, DeviceFileEvents, and DeviceProcessEvents to identify potential compromise.

This rule detects either the execution of specific files identified by SHA256 hashes or the installation/enabling of browser extensions matching known malicious extension IDs. This monitoring helps identify the introduction of potentially harmful browser-based persistent threats or the presence of known malicious binaries on endpoints.

Detects potential Qilin ransomware binaries following Cisco FMC-based intrusion by UAT-11988. Source intel provides only name-level attribution (no sample hash/byte IOC for the payload), so this is tightened to a valid PE, a plausible ransomware-payload size band, and >=2 occurrences of the family string -- a bare single 'Qilin' substring in an arbitrary PE (e.g. an unrelated app, build path, or AV/report string) is not sufficient to alert on alone.

This rule detects the execution of specific suspicious filenames (dirtyah6, tunderflow, pppoeject, diagspill) when they are launched from common staging or temporary directories such as /tmp, /home, or /root, while excluding known build environments, package management directories, and common development workspaces.

This rule detects instances where a process named 'wsc_updata.exe' executing from a Temp directory loads a library named 'wsc.dll'. This behavior is characteristic of DLL side-loading or DLL hijacking, where a malicious or potentially unwanted executable attempts to load a library from a user-writable directory to execute arbitrary code.

Detects the creation of executable or script files within non-system directories that were initiated by the OneDrive sync process. This activity may indicate a user downloading malicious files via a compromised OneDrive account or a malicious payload being synced to the local system.
