Detects creation of a token.cmd file in AppData followed by its execution via cmd.exe within a 5-minute window.
Detects creation of a token.cmd file in AppData followed by its execution via cmd.exe within a 5-minute window.
Detects creation of .git-checker files in temporary directories, a pattern associated with potential malicious activity.

This rule detects the installation or presence of ten identified malicious npm packages associated with the indexed-btree/sorted-btree typosquatting campaign. It monitors command-line activity for 'npm install' commands, package name resolution, and entries within 'package.json' files.
Detects suspicious use of Windows API functions (SetWindowsHookEx) often associated with keylogging, correlated with the presence of temporary staging files in common directories (e.g., Temp, AppData). The rule excludes known legitimate applications that frequently utilize system hooks.
Detects file artifacts referencing OtterCandy malware, which combines OtterCookie and RATatouille RAT capabilities, associated with WaterPlum/Contagious Interview campaign

Detects the obfuscated first-stage JavaScript payload sharedLoad.min.js dropped by the malicious npm indexed-btree package, identified by string-array encoding and self-checksumming array rotation obfuscation patterns

Detects unauthorized modifications, creations, or renames of Pluggable Authentication Module (PAM) configuration files or core shared libraries (such as pam_rootok.so or pam_permit.so) by non-root users. Attackers often modify these files to bypass authentication mechanisms and achieve privilege escalation. The rule excludes common package management tools to minimize false positives.
Detects unauthorized modifications, creations, or renames of Pluggable Authentication Module (PAM) configuration files or core shared libraries (such as pam_rootok.so or pam_permit.so) by non-root users. Attackers often modify these files to bypass authentication mechanisms and achieve privilege escalation. The rule excludes common package management tools to minimize false positives.
Detects a large volume of file write, rename, or creation operations within a single minute by a single process, concurrently with the creation of files containing common ransomware keywords (e.g., 'readme', 'decrypt', 'how_to'). This behavior is characteristic of ransomware encryption activities.
This rule detects potential web shell activity on Microsoft Exchange servers by identifying suspicious processes (like cmd.exe, powershell.exe) spawned by w3wp.exe (IIS worker process) that are associated with the creation or modification of common web shell file extensions (.aspx, .ashx, .asax) within critical Exchange server directories.
This rule monitors for execution patterns associated with the Evil-WinRM tool, a common post-exploitation framework used for remote command execution via WinRM. It identifies suspicious command-line arguments in PowerShell, the creation of configuration files typical of the tool, and network connections to WinRM ports initiated by common execution binaries like PowerShell or Ruby.
Detects a suspicious sequence of events where the Parallels Desktop dispatcher service (prl_disp_service) executes a tar command with a compression program flag, followed immediately by the creation or modification of a launch agent (.plist) file in system or user launch directories. This pattern is indicative of exploitation or post-exploitation activity attempting to achieve persistence.
Detects the creation of suspicious DLL or ASPX files within Microsoft Exchange or IIS directories that are associated with the GhostContainer backdoor, commonly used by the NightEagle threat actor for maintaining persistence.
Detects unauthorized file write operations performed by ScreenConnect client or service processes into client/transfer directories. This activity is indicative of exploitation attempts, specifically CVE-2026-84869, which allows for unauthorized file transfers and potential remote code execution via active ScreenConnect sessions without user confirmation.
This rule detects a sequence of suspicious activities involving files placed in 'ProgramData\Firefox'. It identifies the creation or modification of a non-standard executable within this folder, followed by its execution by a trusted process (or itself), and the subsequent creation of a Registry run key for persistence. This pattern is often used by adversaries for persistence mechanism implementation using masqueraded file names.
