3,989 detections

This rule monitors network, file, and process telemetry for matches against a predefined list of malicious IP addresses, domain names, and file hashes. It flags suspicious network connections to known C2 infrastructure and the presence or execution of known malicious files based on SHA256 and SHA1 indicators.

This rule monitors DeviceNetworkEvents and DnsEvents for connections to known malicious domains and IP addresses associated with phishing campaigns. It alerts on any network communication or DNS resolution attempt targeting these indicators, providing visibility into potential user interaction with phishing infrastructure.

Detects instances where a single process on a device communicates with two or more distinct hosted LLM provider APIs (OpenAI, Anthropic, DeepSeek, Google) within a 24-hour window. This behavior is indicative of multi-model orchestration or 'consensus' techniques, which may be employed by sophisticated implants for automated tasking, data processing, or evasion.

This rule detects network connections to known cryptomining pool IP addresses and domain names, as well as file or process executions matching specific hashes associated with known miner samples. It monitors for communication to command-and-control (C2) servers potentially used for cryptomining operations.

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 outbound HTTP POST requests to the 'vpugy.vcqi' domain, which is associated with RevStealer malware exfiltration. The rule specifically looks for traffic using a spoofed Chrome/147 user-agent and specific cookie artifacts used for session tracking in the exfiltration communication.

Detects execution of PowerShell commands indicative of the VelvetCake variant of the Konni malware. The rule identifies the use of 'Net.WebClient.DownloadString' combined with 'Invoke-Expression' (iex) to execute scripts in memory, alongside specific command-line indicators such as the 'Areyou=cake' campaign marker or associated C2 domains.

Hunts network, HTTP, and email-URL telemetry for known ARToken infrastructure (operator backend IPs and phishing/panel domains). Bounded to a 30-day lookback and tiers matches by confidence: domain hits are high-confidence (attacker-registered infrastructure), while IP hits are medium-confidence since the IPs sit on shared DigitalOcean hosting that can be reassigned to unrelated tenants once ARToken's infrastructure is taken down. Empty/unparsed indicator fields are excluded to avoid spurious matches in the HTTP event parsing branch. No known file hashes are associated with this intel.

This rule detects the presence of ZigCryptoStealer malware deployed via a NativeAOT-compiled Windows executable. The detection relies on identifying specific hardcoded infrastructure strings, such as a BNB Smart Chain RPC endpoint and a specific contract address used to resolve C2 domains. It also looks for common sideloading hosts associated with the malware's delivery.
