Detects incoming HTTP GET requests targeting Vite development server environments that utilize suspicious query parameters typically associated with vulnerability exploitation (e.g., directory traversal or sensitive file access). The rule specifically flags requests where the User-Agent string contains bot keywords but excludes verified IP ranges, suggesting an attempt to bypass security filters by spoofing crawler identities.
Detects incoming HTTP GET requests targeting Vite development server environments that utilize suspicious query parameters typically associated with vulnerability exploitation (e.g., directory traversal or sensitive file access). The rule specifically flags requests where the User-Agent string contains bot keywords but excludes verified IP ranges, suggesting an attempt to bypass security filters by spoofing crawler identities.
Detects instances where a development-oriented web server (such as Vite or Node.js) is configured to bind to all network interfaces ('0.0.0.0') and is simultaneously receiving inbound connections from non-private, external IP addresses on a common development port (5173). This rule filters out common CI/CD environments to focus on potentially insecure exposure of development tools to the public internet.
Detects an exploitation attempt against the Vite Development Server (CVE-2026-39364) where an attacker uses specific query parameters to bypass file access restrictions and disclose sensitive files. The rule triggers on GET requests containing suspicious import-related query parameters and checks the resulting response to ensure a successful 200/206 status code and non-HTML content type.
Detects an exploitation attempt against the Vite Development Server (CVE-2026-39364) where an attacker uses specific query parameters to bypass file access restrictions and disclose sensitive files. The rule triggers on GET requests containing suspicious import-related query parameters and checks the resulting response to ensure a successful 200/206 status code and non-HTML content type.
Detects high-volume bursts of HTTP GET requests against specific paths associated with a Vite development server (/@vite/client, /@fs/, /src/) on port 5173. This pattern is indicative of automated reconnaissance or vulnerability scanning targeting an exposed development environment.
Detects a process that has established a connection to the Telegram Bot API subsequently performing a large volume of file deletions across multiple folders within a 15-minute window. This behavior is indicative of a remote-controlled destructive attack, such as the deployment of a wiper malware (e.g., HEAVYGRAM or CHOSEN BRICK) triggered via Telegram C2 commands.

This rule detects modifications to the Windows Registry 'Run' keys that point to specific, potentially suspicious executable paths located in 'C:\ProgramData\'. These paths are commonly associated with persistence mechanisms used by malware or unauthorized software to ensure execution at system startup.
