Detects network requests to specific GitHub, Blogspot, and Telegram endpoints, which are known to be used by the 'VPN-for-X' extension to fetch proxy configuration files. This behavior is indicative of C2 channel configuration retrieval.
Detects network traffic attempting to connect to known proxy farm fallback hostnames using TLS SNI or HTTP CONNECT methods. These hostnames are often associated with command-and-control infrastructure designed to proxy traffic and mask the true destination of communications.
Detects HTTP GET requests for the path '/wmglb', which is indicative of a SectopRAT stage-two module download (specifically WbElevation.dll) from a Command and Control server.
Detects network activity associated with SectopRAT malware. The rule identifies C2 beaconing behavior on a non-standard port using a custom protocol with a specific 5-byte length header and 16-byte initialization vector, filtering out standard HTTP/TLS traffic.
Detects HTTP POST requests directed to the URI path '/api/credentials' over the non-standard TCP port 8133, which is indicative of AMOS (Atomic macOS) Stealer exfiltrating stolen credentials to a C2 server.
This rule detects high-frequency HTTP GET requests containing abnormally long Base64-encoded strings within the URI. This pattern is often indicative of automated payload assembly or exfiltration where data is fragmented across multiple requests, or the use of URL-shortener services to facilitate C2 communication.
This rule detects security alerts (IDS, WAF, or infrastructure logs) indicating exploitation attempts against JFrog Artifactory instances related to CVE-2026-66384, specifically involving cache poisoning techniques observed in recent threat campaigns.
Detects network activity (TCP, DNS, TLS, HTTP) associated with the UNC6240 threat actor's infrastructure, specifically targeting communications with known malicious IP addresses and domains used in a campaign leveraging PeopleSoft-related lures.
Detects established, bidirectional TCP connections between internal hosts and known infrastructure associated with the SIDEEYE backdoor on specific control and data ports (3333 and 3334).
Detects network activity associated with the LONGTALE malware family (attributed to APT31/JungleBamboo). This includes identification of specific malicious browser extension IDs in HTTP traffic and signature-based detection of periodic HTTPS/HTTP beaconing patterns indicative of session or cookie exfiltration.
Detects DNS queries and TLS SNI traffic directed towards the suspicious domain 'corp.tripswithengine.com', which is associated with the NeedyMantis malware C2 infrastructure.
Detects HTTP beaconing and WebSocket command-and-control (C2) communication associated with the AgtaBackup RAT. This includes identifying specific check-in URIs, hardcoded 'X-Agent-Secret' header authentication, and the initialization of a WebSocket connection.
Detects network requests to known domains (acrobat-reader-installer.com, 03webzoominvite.us) masquerading as Microsoft Store resources to deliver malicious MSI installers. This activity is associated with RMM-based RAT deployment chains.
This rule detects HTTP GET requests to Vercel subdomains targeting a specific path (/secure.html). This behavior is characteristic of phishing campaigns, specifically those masquerading as RMM-related lures to trick users into providing access codes or credentials.
Detects outbound HTTP POST requests destined for 'aware-cr1.com' targeting the URI '/api/beacon', which is indicative of command-and-control (C2) communication associated with the 2CLoader malware.
Detects outbound HTTP POST requests destined for 'aware-cr1.com' targeting the URI '/api/beacon', which is indicative of command-and-control (C2) communication associated with the 2CLoader malware.
Detects outbound HTTP POST requests destined for 'aware-cr1.com' targeting the URI '/api/beacon', which is indicative of command-and-control (C2) communication associated with the 2CLoader malware.
This rule detects HTTP GET requests to a specific IP address (62.60.226.185) attempting to download a file named 't0907.exe'. This pattern is associated with the delivery phase of the 2CLoader malware.
This rule detects HTTP GET requests to a specific IP address (62.60.226.185) attempting to download a file named 't0907.exe'. This pattern is associated with the delivery phase of the 2CLoader malware.
This rule detects HTTP GET requests to a specific IP address (62.60.226.185) attempting to download a file named 't0907.exe'. This pattern is associated with the delivery phase of the 2CLoader malware.
Detects network activity associated with a malicious NPM package (typosquatting) beaconing to a known C2 server (69.48.229.140) and performing command and control operations, including command polling and data exfiltration, specifically from a Node.js environment.
