Detects country-coded lure path requests (/eg, /ma) followed by a cloaking differential response (desktop UA blocked with 404, mobile UA served content). Fixed a regex bug where the original pattern matched any path merely starting with 'eg' or 'ma' (e.g. /egg.jpg, /mail, /manifest.json) instead of the exact path segment.

Detects the Iron Man System phishing kit via its HTTP fingerprint: a request-header rule (ETag/Server/Via combo) checked on the external server's response, and three request-side rules checking for the kit's hashed asset paths and favicon when an internal host requests them from an external site. Fixed a direction bug on the three request-side rules that had source/destination reversed (they previously required an external host to request the path from an internal server, which would rarely if ever fire).

Detects the Iron Man System kit's known template artifact path, and separately its randomized per-deployment admin-panel path shape combined with a Host header on a disposable TLD. Splitting these and requiring the disposable-TLD host on the generic admin-path rule avoids matching legitimate multi-tenant apps or hardened CMS installs that use similar random-path-plus-/admin/ obfuscation on ordinary domains.

This rule detects network traffic directed at known command and control (C2) domains associated with the Koktevrat malware, specifically targeting the domain 'fb-market-play.cc'. This pattern is indicative of compromised hosts attempting to communicate with attacker infrastructure, often following an initial infection phase initiated via malicious links.

Detects successful exploitation attempts targeting Vite development servers via chained access-control bypass vulnerabilities (CVE-2025-30208, CVE-2025-31125, CVE-2024-45811). The rule identifies malicious GET requests using the /@fs/ endpoint with specific query parameters, resulting in a successful HTTP 200 response, while originating from non-internal IP addresses.

Detects outbound network traffic to the Telegram Bot API where the request body contains keywords associated with cryptocurrency wallet software (e.g., MetaMask, Phantom, Tron). This behavior is indicative of a malicious script, possibly embedded in a Google Docs sidebar or similar web-based application, exfiltrating host/browser information or wallet-related data to an attacker-controlled Telegram bot.

Detects high-frequency requests to the RubyGems legacy API key endpoint, which may indicate attempts to harvest or bruteforce developer API keys. The rule specifically monitors for request patterns involving variations like .yaml, .json, or parameter-based variants often observed in scanning activities.

This rule detects potential Server-Side Request Forgery (SSRF) attempts targeting specific UK council ModernGov websites (e.g., Lambeth, Wandsworth, Southwark). It looks for outbound HTTP requests from non-browser clients (specifically identifying 'Ruby' in the User-Agent string) to these specific gov.uk domains, with a threshold to catch repeated attempts.
