Detects node.exe (Node.js runtime) process initiating file read operations on sensitive files such as SSH keys, AWS credentials, Docker configuration files, GPG keyrings, or package manager configuration files (npmrc/pypirc). This behavior is characteristic of malicious npm packages or infostealers attempting to exfiltrate developer credentials, as observed in the Polymarket Trap supply chain campaign.
Detects unauthorized access or modification attempts to cryptocurrency wallet files (specifically MetaMask and Phantom browser extensions) by non-browser processes. This behavior is indicative of credential theft or wallet exfiltration by malicious software.
Detects malicious activity associated with npm supply chain compromise, including execution of known malicious npm lifecycle scripts, DNS queries to suspected C2 domains, and unauthorized access to sensitive developer credential files (such as .npmrc, .aws/credentials, and SSH keys) by Node.js processes.
Detects indicators of the BUMSRAKETE exploit, specifically looking for malicious binary names, staging files, and a high-frequency loop pattern involving SUID binaries (su, passwd) by unprivileged users. This pattern is consistent with a kTLS page-cache corruption exploit targeting CVE-2026-45257.
Detects instances where JavaScript runtime processes (node, npm) execute specific peer-related or verification scripts and subsequently access sensitive system files or directories, such as SSH configurations, AWS credentials, or browser data, within a 5-minute window.
This rule detects when processes other than standard web browsers (Chrome, Edge, Firefox, Brave, Opera) attempt to read sensitive browser data files such as 'Login Data', 'Cookies', or 'Web Data'. These files contain stored credentials and session information, and unauthorized access is a common technique used by credential-stealing malware to exfiltrate sensitive user information.
This rule detects when the 'oskmenu.xml' file, located in 'C:\Program Files\Common Files\microsoft shared\ink\fsdefinitions', is accessed or modified by any process not running under the SYSTEM account. This file is associated with the On-Screen Keyboard and its modification by non-system accounts could indicate an attempt to alter its behavior, potentially for persistence or privilege escalation.
This rule detects attempts to access the Local Security Authority Subsystem Service (LSASS) process memory or the NTDS.dit file, which are common targets for credential dumping. It specifically looks for Security Event ID 4656 (A handle to an object was requested) where the ObjectName is either 'lsass.exe' or 'ntds.dit' and the AccessMask indicates read or all access permissions. The rule then summarizes these events by user, computer, and IP address, flagging if two or more such events occur.
This rule monitors Linux authentication logs for anomalies related to Pluggable Authentication Modules (PAM). It identifies potential security risks by detecting file operations (read, write, create) within PAM-related processes, references to world-writable or temporary directories that may be used for staging credentials, and unusual authentication event patterns.
Detects potential credential harvesting activities targeting the SSH and PAM authentication stacks. The rule identifies suspicious file operations (creation/modification/read) by authentication-related processes (sshd, login, su, sudo) involving sensitive files like /etc/shadow or non-standard file paths in temporary directories, as well as the spawning of interpreters that write to these suspicious locations.
Detects suspicious execution of Python or shell scripts (bash, zsh, sh) from paths associated with 'openclaw' or 'clawhub' that are interacting with sensitive data files, including browser credential stores (Chrome, Firefox, Edge, Brave), system keychains, and cryptocurrency wallet files.
Detects attempts to access or copy the Active Directory domain database (NTDS.dit) by monitoring for direct file access to the file or the execution of ntdsutil.exe with arguments intended to create an Install From Media (IFM) set, which is a known technique for exfiltrating the NTDS.dit file for offline password cracking.
Detects unauthorized attempts to access or list stored credentials via Windows Credential Manager using standard administrative tools (cmdkey.exe, vaultcmd.exe) or PowerShell, as well as direct unauthorized access to credential storage files within the AppData directory.
This rule detects suspicious SMB traffic targeting raw disk volumes (e.g., PhysicalDrive, C:) or sensitive Windows files such as NTDS.dit and SYSTEM hive files. This behavior is indicative of credential dumping attempts, often performed using tools like secretsdump.py or Invoke-NinjaCopy, which bypass standard file system access controls to exfiltrate critical system credentials.
Detects techniques associated with Golden SAML attacks, including the use of Mimikatz for ADFS token-signing certificate extraction, the execution of AADInternals PowerShell cmdlets for SAML token forgery, and unauthorized access to the ADFS configuration database (AdfsConfiguration.mdf).
Detects unauthorized attempts to access or list stored credentials via Windows Credential Manager using standard administrative tools (cmdkey.exe, vaultcmd.exe) or PowerShell, as well as direct unauthorized access to credential storage files within the AppData directory.
Detects various techniques used by an attacker to escape a container environment or gain unauthorized access to host-level resources. This includes the execution of namespace manipulation tools (nsenter, unshare, chroot), unauthorized access to the docker.sock Unix socket, mounting of host filesystems from within a container, and direct attempts to access the host's /proc/1 namespace files.
Detects the unauthorized access or copying of the Active Directory NTDS.dit database file, a common credential harvesting technique. The rule monitors for the execution of ntdsutil.exe or vssadmin.exe with arguments typically used to create shadow copies or extract the NTDS database, specifically when executed by cmd.exe or powershell.exe.
Detects unauthorized processes attempting to access or perform operations on sensitive files such as browser credentials, SSH keys, crypto wallets, and password manager databases. The rule specifically looks for non-standard or unsigned processes interacting with a high volume of these files in a short time frame, which is indicative of credential harvesting by infostealer malware like Lumma, Redline, or Vidar.
Detects unauthorized access to Windows Credential Manager files, TokenBroker OAuth cache files, or the loading of crypt32.dll from suspicious, user-writable directories (e.g., Temp, Downloads, Desktop) by non-Microsoft or non-system processes. This activity is indicative of credential theft, session hijacking, or attempts to abuse the Windows Data Protection API (DPAPI) to decrypt sensitive local secrets.
Detects reconnaissance activity associated with Pay2Key ransomware, specifically sandbox or environment checks. This includes process lineage originating from 7ZipSfx temporary directories combined with registry queries for S-1-5-19 (SYSTEM account) or direct file system access to Avast installation directories to verify the presence of security software.
