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
Detects HTTP POST requests directed to the '/api.php' endpoint with specific patterns characteristic of Exvicy/ClickFix malware C2 communication. The rule identifies suspicious action parameters (check, dl, or cb) and a specific 48-character hexadecimal 'k' parameter used for identifying infected state.
Detects outbound network traffic from internal hosts to a domain associated with the VelvetCake fileless malware variant. The rule specifically looks for HTTP requests to 'p1o2i3u4y5t6r7e8w9q0.medianewsonline.com' using specific login parameters ('Areyou=cake', 'OKey=', 'Who='), which is indicative of command and control activity linked to the Konni actor group.
Detects HTTP POST requests directed at etherscan.io containing 'eth_call' in the request body. This pattern is indicative of the GHAPPIER / PolinRider malware family utilizing the Ethereum blockchain's public JSON-RPC interface as a dead-drop resolver for command-and-control communication.
Detects anomalous DNS traffic patterns indicative of command-and-control (C2) or data exfiltration over the DNS protocol. The rule identifies suspicious queries containing long, high-entropy subdomain labels that suggest payload encoding, as well as the use of TXT records for unauthorized data transmission.
This rule detects HTTP traffic where a response from a Google Cloud Storage bucket (storage.googleapis.com) initiates a redirect via meta-refresh or JavaScript to a Vercel-hosted domain. This pattern is indicative of phishing infrastructure, where attackers leverage legitimate, trusted storage platforms to redirect users to malicious landing pages.

This pattern is indicative of phishing infrastructure, where attackers leverage legitimate, trusted storage platforms to redirect users to malicious landing pages.
Detects two distinct methods of living-off-the-land proxy execution: first, MSBuild.exe spawning network connections after executing inline tasks defined in XML project files; second, Regsvr32.exe performing 'Squiblydoo' execution by loading COM scriptlets from remote URLs.
Detects anomalous DNS traffic patterns indicative of DNS tunneling, which is often used for command-and-control (C2) communication or data exfiltration. The rule identifies suspicious indicators such as abnormally long subdomain labels (potentially containing encoded payloads), misuse of TXT or NULL record types for data transport, and high-frequency queries to a single apex domain, while excluding common CDN providers to reduce false positives.
Detects network activity (TCP, DNS, TLS, HTTP) associated with the UNC6240 threat actor's infrastructure, specifically targeting communications with known malicious IP addresses and domains used in a campaign leveraging PeopleSoft-related lures.

Detects established, bidirectional TCP connections between internal hosts and known infrastructure associated with the SIDEEYE backdoor on specific control and data ports (3333 and 3334).

This rule detects the execution of the MeshAgent remote administration tool from a temporary directory followed by a network connection to known malicious infrastructure within a 15-minute window. This behavior is indicative of unauthorized remote access setup or C2 activity using a legitimate remote management utility.

Detects the execution of the 'fanout.sh' utility from the /tmp directory, which subsequently spawns 'sshpass' child processes to perform rapid, non-interactive SSH authentication attempts ('StrictHostKeyChecking=no') against multiple internal hosts within a 10-minute window. This behavior is indicative of automated lateral movement, specifically observed by threat actor UNC6240.
