Detects suspicious activity associated with Cobalt Strike Beacon communication, specifically monitoring for known default named pipes and specific user-agent strings commonly used by Cobalt Strike in HTTP/S traffic.
Detects the initiation of a new process where the effective user context is SYSTEM, but the originating process was launched by a non-privileged user account. This behavior is indicative of token manipulation techniques such as token impersonation or theft (e.g., via DuplicateTokenEx or ImpersonateLoggedOnUser) to escalate privileges to SYSTEM.
Detects the presence of specific Go build path metadata associated with the sckit Go implant, including modules and internal package structures, within an executable or file.
This rule detects potential persistence mechanisms involving the creation of 'Locked' registry keys within Software\Classes and subsequent use of Run registry keys that reference 'Locked://' URIs. It also identifies suspicious execution of rundll32.exe utilizing specific CLSID-based command line arguments associated with the '{CFDC57BA-1705-45AF-BA10-EFC3D592982B}' identifier, often linked to malicious activity patterns.
Detects suspicious activity associated with the DarkMe RAT, specifically targeting cryptocurrency wallet data files. The rule correlates file access to known wallet data paths by a hollowed process 'clspack.exe', followed by suspicious outbound network activity originating from that same process, and potentially preceded by WMI-based antivirus enumeration.
Detects Node.js processes establishing network connections to common webhook relay and collection services, which may indicate data exfiltration or credential theft.
Detects instances where the Firefox browser or its plugin container process initiates a DNS query for domains containing 'pdf.gusercontent.com', which is a known lookalike pattern used to masquerade as legitimate Google infrastructure for potential command and control or data exfiltration activities.
Detects the installation of known malicious npm or PyPI packages followed within 30 minutes by the execution of a package manager (node or python) performing network activity. This pattern matches the behavior of downloader stages in the 'Graphalgo' campaign, which uses coding-task lures to trick users into installing malicious packages.
Detects the creation of suspicious scheduled tasks using the Windows schtasks.exe utility. The rule flags tasks that are configured to run as SYSTEM, include PowerShell encoded commands, or target directories commonly used for persistence such as Temp, AppData, or Public.
Detects potential exfiltration of sensitive DevOps credentials or configuration files (such as AWS credentials, SSH keys, Kubernetes configs, or cryptocurrency wallets) by monitoring for file access events followed by outbound network connections to known exfiltration channels like Slack or specific C2 infrastructure within a 30-minute window.
This rule detects attempts by an attacker to disable or modify Windows security software and features. It monitors for three distinct behaviors: execution of 'Set-MpPreference' to modify Windows Defender settings (exclusions or real-time monitoring), execution of 'sc.exe' to stop security-related services (such as EDR or AV services), and direct modification of Windows registry keys to disable Windows Defender components.
Detects the abuse of Windows Management Instrumentation (WMI) to execute processes via wmic.exe or WmiPrvSE.exe, often combined with obfuscated command-line arguments such as encoded PowerShell or CMD commands.
Detects unauthorized processes (other than known browsers like Chrome, Edge, or Firefox) attempting to access sensitive browser files such as 'Login Data', 'Cookies', or 'Web Data'. This behavior is commonly associated with credential stealing or browser session hijacking.
Detects user-initiated execution of scripts or binaries directly from the root of a drive letter. This pattern is commonly associated with phishing campaigns delivering malicious payloads via mounted ISO or IMG files, which allow attackers to bypass mark-of-the-web or macro security controls.
Detects instances where a Terraform provider process spawns a child process (go.exe or cmd.exe) to execute 'go run .'. This behavior is atypical for standard Terraform provider execution and may indicate the use of malicious providers that compile and execute code on-the-fly, a technique used to evade signature-based detection.
Detects attempts to create a memory dump of the Local Security Authority Subsystem Service (LSASS) using either the built-in 'comsvcs.dll' library via 'rundll32.exe' or by requesting specific sensitive process access rights to 'lsass.exe' from unauthorized processes.
Detects user-initiated execution of scripts or binaries directly from the root of a drive letter. This pattern is commonly associated with phishing campaigns delivering malicious payloads via mounted ISO or IMG files, which allow attackers to bypass mark-of-the-web or macro security controls.
Detects the installation or execution of common remote access tools (e.g., AnyDesk, ScreenConnect, Atera, Splashtop) using silent or unattended installation flags. This rule explicitly excludes activity originating from known administrative and management platforms such as Microsoft Intune and SCCM.
Detects a Go toolchain process (go.exe) spawning potentially suspicious child processes such as secondary 'go run' commands or Node.js execution. This behavior is indicative of a malicious Go module executing embedded or decrypted code during the build process, a tactic seen in supply chain attacks targeting development environments.
Detects instances where a process that is not a recognized web browser accesses or enumerates the file storage path of the MetaMask browser extension. This behavior is indicative of unauthorized reconnaissance or credential theft attempt targeting cryptocurrency wallet data stored locally, often performed by malware following successful system compromise.
Detects the use of legitimate Windows binaries (certutil.exe and bitsadmin.exe) to download files from remote URLs to sensitive or common staging directories (Temp, AppData, ProgramData). Attackers frequently abuse these built-in tools for 'living off the land' (LotL) to retrieve malicious payloads or secondary tools while bypassing traditional signature-based detection.
