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 DNS queries for the hardcoded domain 'gsx.uk.com', which is associated with the command-and-control (C2) infrastructure of BabylonRAT malware.

This rule detects network traffic patterns associated with the Koktevrat Android RAT, specifically identifying periodic TLS beacons (heartbeats) destined for known C2 domains (streams-tv.lol and stream-plus.lat). The behavior suggests the use of Android's AlarmManager to schedule recurring callbacks to the C2 infrastructure.

This rule detects outbound TLS connections to suspicious domain names characteristic of the Koktevrat malware's DGA. The rule identifies SNI strings that match a specific regex pattern (8-16 alphanumeric characters followed by .icu or .cfd TLDs), which is indicative of automated C2 communication.

Detects outbound network communication patterns (DNS lookups and TLS SNI traffic) associated with the Koktevrat Android RAT. The rule monitors for connections to known malicious domains used for command-and-control (C2) operations.

Detects specific command strings ('proxy_open', 'proxy_data', 'proxy_close') associated with the Koktevrat Android RAT's tunneling functionality. The rule monitors outbound TCP traffic to identify the initiation, data transfer, and termination phases of a proxy connection, leveraging Suricata flowbits to track the state of the C2 tunnel.
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 incoming HTTP POST requests to the GitLab '/import' endpoint that attempt to access the internal cloud metadata service (169.254.169.254), indicating an exploitation attempt for vulnerabilities such as CVE-2021-22175 or CVE-2021-39935.
Detects high-frequency connection attempts to PPTP (1723) and L2TP (1701) VPN ports from an external source, indicative of automated scanning or vulnerability discovery activity.
This rule detects potentially malicious use of residential proxies by monitoring for outbound HTTP CONNECT requests originating from consumer devices in the internal network. The use of HTTP CONNECT is a common method for establishing tunnels through proxies to mask C2 communication or facilitate unauthorized access, often associated with botnets or malicious proxy networks.

This rule detects high-frequency TCP SYN connection attempts originating from external networks targeting common administrative or tunneling ports (1723/PPTP, 1701/L2TP, 22/SSH) on internal systems. The detection uses a threshold of 100 connection attempts within 120 seconds, which is characteristic of automated reconnaissance and network scanning behavior.
