Detects the execution of a malicious npm package disguised as '@withgoogle/stitch-sdk'. The package uses a 'preinstall.js' script to harvest sensitive developer credentials, including API keys, Git credentials, SSH keys, and Docker tokens, and attempts to exfiltrate this data to an attacker-controlled domain (stitch-production.org).
Detects the creation of executable files (.exe or .dll) on a removable drive followed by the execution of a process from that same drive within a 30-second window. This behavior is indicative of an adversary using removable media to stage and execute malicious payloads.
Detects post-exploitation activities related to the CVE-2026-45257 BUMSRAKETE vulnerability on FreeBSD. The rule monitors for kernel module loading using kldload from suspicious directories, kldstat execution, unauthorized root-level crontab modifications, and suspicious root-level shell execution spawned from non-standard parent processes, all of which indicate potential persistence or rootkit installation following a local privilege escalation.
Detects exploitation attempts against Langflow targeting unauthenticated API endpoints (/api/v1/build_public_tmp or /run) for remote code execution, as well as downstream process spawning activity on Linux hosts where Python processes execute shell commands (e.g., curl/wget piping to sh) to download known malicious dropper payloads.
Detects execution of the BUMSRAKETE exploit targeting the CVE-2026-45257 FreeBSD kTLS-RX page-cache corruption vulnerability. The rule identifies the exploit binary launching from a non-privileged context alongside the creation of staging files used to corrupt system binaries and escalate privileges to root.
Detects evidence of log and artifact tampering on a Windows host, specifically the clearing of Windows System or Security logs using wevtutil or PowerShell, the stopping of the EventLog service, or the deletion of PowerShell PSReadLine history files. Such activity is often conducted by an adversary to conceal malicious actions.
This rule detects the creation of scheduled tasks using either schtasks.exe or PowerShell (Register-ScheduledTask) that exhibit high-risk indicators. These indicators include executing files from suspicious locations (AppData, Temp, or specific user-writable directories), the use of encoded PowerShell commands, or initiation by common remote access tools (sshd, ssh, or mstsc). This behavior is often associated with persistence mechanisms used by adversaries.
Detects the execution of Python scripts that include libraries (pynput, pyxhook) or functions (GetAsyncKeyState, WH_KEYBOARD_LL) frequently used by keyloggers to capture user keystrokes. It also monitors for suspicious input device access and command-line arguments indicative of keystroke monitoring.
Detects non-privileged execution of system commands (sysctl, freebsd-version, uname) used to query kernel parameters and system configuration. These actions serve as reconnaissance prerequisites for exploiting the BUMSRAKETE (CVE-2026-45257) local privilege escalation vulnerability on FreeBSD systems.
Detects execution and post-exploitation behaviors associated with the BUMSRAKETE exploit, specifically targeting page-cache overwrite privilege escalation (CVE-2026-45257). The rule identifies the presence of malicious binaries, staging artifacts in /tmp, and unprivileged processes spawning shells via SUID binaries (su, passwd) that indicate successful exploitation.
Detects execution of the RustDesk remote access tool from non-standard, user-writable directories, or when spawned by suspicious parent processes such as shells or scripting hosts. This rule is designed to identify unauthorized use of RustDesk as a persistence or remote access mechanism by adversaries attempting to bypass standard software management.
Detects indicators of the BUMSRAKETE exploit targeting a FreeBSD kernel page-cache corruption vulnerability (CVE-2026-45257). The rule triggers on the execution of the exploit binary, creation of specific staging files in /tmp, unauthorized access to SUID binaries, configuration of kTLS socket options (TCP_RXTLS_ENABLE/TCP_TXTLS_ENABLE) by unprivileged users, and pre-exploit reconnaissance using sysctl.
Detects suspicious execution patterns originating from or associated with crontab, crond, or anacron processes. The rule identifies potential persistence or malicious task scheduling by monitoring specific command-line indicators such as execution from /tmp or /dev/shm, unusual execution intervals, or specific shell command patterns associated with cron job abuse.
Detects the spawning of common command-line shells (cmd.exe, powershell.exe, net.exe) by the Windows Remote Management (WinRM) process, wsmprovhost.exe. This activity is indicative of lateral movement or remote command execution via WinRM.
Detects the use of built-in Windows utilities (vssadmin, wbadmin, bcdedit) to delete volume shadow copies, clear backup catalogs, or modify boot configuration settings to disable recovery features, which is a common precursor to ransomware encryption.
Detects the creation or modification of Windows Management Instrumentation (WMI) event subscriptions (filters, consumers, and bindings) that target potentially malicious destinations like cmd.exe, PowerShell, or files located in common user-writable directories like Temp or AppData, or multiple concurrent WMI subscription activities which may indicate persistence mechanisms.
Detects trusted .NET tooling launching shells, scripting engines, or administrative utilities that are not typically associated with legitimate compilation workflows, potentially indicating malicious execution or post-exploitation.
Detects the China Chopper web shell spawning CMD from IIS (w3wp.exe) with suspicious command line patterns.
Detects the use of regsvr32.exe to execute a remote scriptlet (.sct file) via a URL, a technique often referred to as 'Squiblydoo'. This method bypasses application control by leveraging a trusted Microsoft binary to proxy execution of malicious code.
This rule detects a high volume (5 or more within an hour) of process creation events where the command line contains keywords associated with remote access protocols like DCOM, WMI, or RPC. This could indicate an adversary utilizing these protocols for lateral movement or remote execution.
This rule detects the creation of a Windows service where the service type is set to 'kernel' via the sc.exe command-line utility. This behavior is indicative of an attempt to load a kernel driver or perform low-level system modifications, which is often used by rootkits or malicious drivers. The rule filters out known trusted publishers to reduce noise.
