Detects anomalous DNS activity characterized by high-frequency IP address rotation for a single domain within a 10-minute window. This behavior is indicative of fast-flux DNS techniques used by attackers to maintain C2 infrastructure and evade domain-based blocking or IP reputation filtering.
Detects an endpoint initiating outbound network connections to three or more distinct LLM provider APIs (DeepSeek, Qwen, Mistral, Gemini) within a short timeframe (15-minute windows). This behavior aligns with the multi-provider voting mechanism used by the CLOSEDQUORUM post-compromise framework to autonomously determine subsequent actions using diverse generative AI models.
Detects a suspicious sequence of events: an anomalous login (new device, new location, or high-risk sign-in) followed by the assumption of a highly privileged role (via AssumeRole, PIM, or role elevation) and subsequent sensitive administrative actions (e.g., creating access keys, modifying IAM policies, or disabling security auditing). This pattern is indicative of cloud identity compromise and privilege escalation, commonly seen in attacks involving groups like Scattered Spider.
Detects unauthorized, unsigned processes accessing sensitive browser files (Cookies, Login Data, Local State) across common browsers (Chrome, Edge, Brave, Firefox) followed by an outbound network connection. This behavior is indicative of credential-harvesting infostealer malware.
Detects a suspected automated exploitation sequence where a web storefront file (e.g., .phtml, .js, .php) is modified to inject malicious script code (skimmer), followed by an unauthorized SQL DELETE operation on sensitive database tables containing payment, customer, or order information, originating from the same host within a 6-hour window.
Detects high-volume authentication failures originating from a single source IP targeting multiple unique user accounts, indicative of password spraying or credential stuffing attacks against cloud identity providers.
Detects the deployment of the CARBONATO botnet's Hermes Agent within containerized environments. The rule identifies specific artifacts such as the 'SOUL.md' persona configuration, 'netd-svc' container references, and indicators of AI-focused credential theft (e.g., searching for OpenAI or Anthropic API keys) orchestrated by the GH0ST AI agent.
Detects outbound connections to a known malicious C2 infrastructure associated with the CARBONATO threat actor. The rule identifies both established SSH sessions using the OpenSSH implementation and the initiation of outbound TCP connections on ports dynamically determined by an MD5 hash, which is a known behavior of this actor's C2 communication strategy.
This rule monitors for suspicious interactions with Android device drivers via the 'getevent' utility, often used to capture raw input, combined with unusual file access patterns involving 'locateValues.json' and potential data exfiltration attempts to specific internal API endpoints.
Detects malicious persistence activity on Android devices originating from an ADB or shell context (UID 2000). The rule monitors for a sequential pattern: the silent re-installation of the 'RatHat' APK package via 'pm install' commands, followed by the modification of system security settings to re-grant Accessibility Service permissions.
