Detects unauthorized processes accessing the 'ConsoleHost_history.txt' file across user profiles. This behavior is indicative of ransomware operators or malicious actors attempting to harvest stored credentials, tokens, or sensitive command-line history before performing lateral movement or privilege escalation.

Detects the execution of PowerShell scripts 'first.ps1' and 'main1.ps1', which are components of a known credential phishing toolset. This tool displays a fake Windows Update dialog to trick users into providing their credentials, which are then exfiltrated via SMB, DNS, or HTTP.

Detects rapid, machine-speed, sequential attack-path adaptation by suspected AI agent binaries. The rule monitors for a correlation of four stages occurring within a tight 20-minute window: 1) Failed service connections across three or more distinct protocols (SMB, SSH, HTTP, RDP, WinRM), 2) Credential access attempts (Logon events or execution of known credential-dumping tools), and 3) A lateral movement pivot to a new, previously un-targeted internal destination. The rule specifically keys on the InitiatingProcessId and InitiatingProcessCreationTime to ensure the sequence is attributed to a single process instance, distinguishing it from human manual penetration testing activity. Covers T1190, T1210, T1078

This rule detects a sequence of events indicative of MacSync credential phishing on macOS. It identifies the tampering of Pluggable Authentication Modules (PAM) configuration files or SecurityAgent plugins (often used to hook authentication processes), immediately followed by the use of osascript to display a spoofed password dialog to the user. This combined activity suggests an adversary is attempting to harvest local user account credentials.

402
Detects the SCKit Go-based credential-stealing implant found in compromised npm and PyPI packages. The detection logic focuses on unique build-info module paths, specific C2 encryption protocol headers, and embedded campaign identifiers related to 'memos-cloud-openclaw-plugin' and 'MemoryOS' supply chain compromises.

Detects instances where a process other than a known legitimate web browser attempts to read or enumerate files within the MetaMask browser extension directory or related local settings. This behavior is indicative of a Remote Access Trojan (RAT) or information-stealing malware performing reconnaissance to target cryptocurrency wallet data stored within the browser's profile.

003
Detects instances where common scripting or development language runtimes (Go, Node.js, WScript, CScript) access sensitive configuration or credential files, such as AWS credentials, Kubernetes configs, SSH keys, or environment files. This activity is often indicative of credential harvesting or unauthorized access to sensitive secrets by potentially malicious scripts or processes.

003
Detects suspicious process access attempts targeting common web browsers (chrome, msedge, firefox) using high-privilege access masks (such as 0x1F0FFF or 0x1FFFFF). The detection is specifically scoped to calls originating from unbacked memory (indicated by an UNKNOWN stack trace entry containing ntdll.dll), which is a common indicator of direct or indirect syscalls used by malware for stealthy memory access, such as credential theft or session cookie exfiltration.

Detects a specific attack chain attributed to ClosedQuorum, involving LSASS memory dumping, subsequent access to browser-based credential stores or cryptocurrency wallet files, and finally staging the stolen data in C:\Windows\Temp\ within a short time window.

Detects the Sckit Go implant accessing sensitive local configuration and credential files, including SSH keys, cloud CLI tokens, and package manager credentials. The rule monitors for file read events initiated by processes identified as 'sckit' or processes with specific command line arguments.

Detects the pidclone-style LSASS credential dumper that clones the target process into a suspended state, mirrors its memory, generates a minidump, and writes an XOR-encrypted copy of the dump to a randomized filename under Windows\Temp

001
Detects a process initiating a memory dump of lsass.exe (using --dump arguments) followed within 15 minutes by the creation of a hexadecimal-named .tmp file in the Windows\Temp directory. This behavioral pattern is characteristic of credential dumping using reflected cloning or similar techniques, followed by the staging of obfuscated or encrypted minidump data for exfiltration.

This rule detects high-frequency HTTP 401 Unauthorized responses directed at API endpoints (specifically matching '/v1/') within a short window, which is indicative of an adversary attempting to brute-force or credential-stuff API keys.

Detects the use of rundll32.exe to execute comsvcs.dll's MiniDump functionality against the LSASS process, a common technique for dumping credentials. The rule includes behavioral correlation by identifying the same user account executing this pattern on multiple devices within a one-hour window.

Detects the execution of known Python scripts (CES_Enroll.py, ntlm_ces_relay.py, ces_negotiate_ntlm.py) often associated with NTLM relay attacks or forced authentication techniques. These scripts leverage Python to interact with authentication protocols or relay requests.

Detects the execution of known NTLM Certificate Enrollment Service (CES) relay tools alongside subsequent outbound network connections to Active Directory Certificate Services (AD CS) CES enrollment endpoints. This behavioral pattern indicates an adversary attempting to relay NTLM authentication to an AD CS server to request a certificate, typically for privilege escalation or persistence.
