Detects potential Pass-the-Hash (PtH) activity by monitoring Windows Security Event ID 4624 (Logon). The rule specifically targets logon type 9 (NewCredentials) combined with specific process/package names indicative of tools like Mimikatz, or anomalous NTLM network logons (logon type 3) that are not anonymous.
Detects instances where common browser credential and cookie storage files (Login Data, Cookies) for Google Chrome or Microsoft Edge are accessed by non-browser processes such as PowerShell, csc.exe, or the Search Indexer. This behavior is highly indicative of credential theft or session hijacking attempts.
Detects outbound web or proxy connections to known consumer-grade cloud storage and file-sharing services. This activity is often indicative of data exfiltration, where an adversary uploads staged or archived sensitive data to third-party file hosting services (e.g., Mega, Dropbox, transfer.sh, pastebin) to bypass traditional enterprise exfiltration controls.
This rule detects potentially unauthorized or suspicious repository interactions by monitoring 'git' commands executed by common AI-assisted coding tools or command-line developer utilities. It flags occurrences where a checkout operation occurs without accompanying standard git history or status checks, which may indicate automated exfiltration or lateral movement attempt within a developer environment.
Detects a single developer identity performing a high volume of git push or clone operations across a large number of distinct repositories within a short timeframe. This behavior is indicative of a compromised developer account being used to programmatically inject code into multiple repositories, potentially for a supply chain attack or mass payload propagation.
Detects an identity that performs a 'ListSecrets' operation followed by a high volume of 'GetSecretValue' or 'BatchGetSecretValue' requests within a short timeframe (15 minutes). This behavioral pattern is indicative of automated bulk exfiltration of secrets from AWS Secrets Manager, a common activity following an initial cloud environment compromise.
Detects the execution, network connections, and service installation of MeshAgent or associated binaries (e.g., mvtcs.exe). The rule identifies potential unauthorized or malicious use of this remote management software by looking for process activity, specific network connections to known infrastructure, and service persistence mechanisms.
This rule detects the creation of Git branches or tags using names that match the 40-character or 64-character hexadecimal format of Git commit hashes. This technique, identified in the context of Plugin4Shell, is used to spoof pinned-commit references, potentially misleading automated systems or developers into using malicious code versions.
Detects a git checkout to a specific SHA followed by a git rev-parse HEAD verification command within AI coding assistant plugin directories (e.g., claude, codex, copilot, gemini). This pattern is monitored to identify potential supply chain compromises where a working tree might be silently substituted during plugin installation or updates.
This rule detects potential Pass-the-Hash lateral movement by identifying NTLM network logons (Event ID 4624, LogonType 3) on a host that lack a preceding interactive (LogonType 2, 10) or Kerberos-authenticated logon, coupled with subsequent access to sensitive administrative shares (Event ID 5140) by the same user account.
