Detects network traffic indicating a HEAVYGRAM malware instance communicating with the Telegram Bot API. This is identified by monitoring encrypted TLS traffic to api.telegram.org, which is a common technique used by malware to establish a command-and-control channel using legitimate web services.
Detects network traffic indicating a HEAVYGRAM malware instance communicating with the Telegram Bot API. This is identified by monitoring encrypted TLS traffic to api.telegram.org, which is a common technique used by malware to establish a command-and-control channel using legitimate web services.
Detects outbound network traffic to the Telegram Bot API (api.telegram.org) indicative of long-polling command and control (C2) communication. This behavior is associated with the HEAVYGRAM malware and its use of Telegram as a C2 channel.
Detects network activity associated with the Handala Loader malware, specifically identifying attempts to download disguised shellcode or malicious payloads from deadhub.org and associated infrastructure. The rule monitors for specific URI patterns mimicking UI assets and fallback communication attempts to known C2 IP addresses.
This rule detects DNS queries and network connections to a curated list of domains identified as malicious. It correlates events from DNS logs and device network logs to identify potential command-and-control (C2) or malicious infrastructure interaction.
This rule monitors for outbound network connections to domains and IP addresses associated with known phishing, loader, and C2 infrastructure, including specific ClickFix patterns.
Detects a network connection to potentially malicious infrastructure or non-standard ports following a request to ipify.org, which is commonly used for external IP reconnaissance by malware and C2 frameworks.
Detects repeated, non-interactive requests to the Google Sheets Visualization API (gviz/tq) originating from common web browsers. This pattern is indicative of a malicious browser extension attempting to reconstruct or reinject payloads when a user visits specific targeted websites.
Detects network connections initiated by common web browsers to a specific LinodeObjects domain or any subdomains within the linodeobjects.com infrastructure, which may indicate command and control communication or data exfiltration via legitimate cloud storage providers.
Detects activity associated with the 'MovieReaper' threat campaign by identifying known malicious file hashes, command and control (C2) IP addresses, and communication with identified malicious domains. This rule monitors process execution, file operations, and network connections within the campaign's active timeframe.
Detects established TLS outbound connections to external networks on ports other than standard ones (e.g., 443, 465, 587, 993, 995, 8443, 9443). This behavior may indicate a covert C2 channel or unauthorized data exfiltration attempting to bypass standard firewall controls.
This rule detects potentially malicious interaction with specific GCP service account identifiers and client IDs. It monitors multiple log sources—including cloud audit logs, sign-in activity, security logs, and device network events—to identify unauthorized access, command and control communication, or data exfiltration attempts targeting Google API services (specifically oauth2.googleapis.com and sheets.googleapis.com).
Detects instances where internal devices access the 3BB sales portal (agent.3bb.co.th) while demonstrating signs of compromise. The rule correlates the portal access with recent network activity involving identified MeshCentral attacker infrastructure (ayuthayatech.com or 92.63.180.133) and further filters for behavioral anomalies such as off-hours access, the use of non-standard browser processes, or the use of unexpected service accounts.

Detects network requests to the Gitea Prometheus metrics API that contain 'k=' and 'x=' query parameters, a pattern indicative of a C2 command channel disguised as legitimate telemetry traffic.

Detects execution of the JITTERLY Linux backdoor masquerading as 'configd' (with its -nodel fallback flag) and/or beaconing to its hardcoded C2 domain (s2.981666.xyz:8082), matching Red Heron's observed tradecraft.

Detects repeated manual HTTP GET requests from many distinct source IPs to a canary token resource. The URI pattern follows a format indicative of a tracked canary token resource, and the threshold of 49 unique source IPs accessing the resource within a prolonged period suggests potential unauthorized reconnaissance or probing activities.
Detects network activity communicating with Google Drive domains (drive.google.com and www.googleapis.com). This rule monitors outbound traffic, which may indicate the use of Google Drive as a command-and-control (C2) channel or for unauthorized data exfiltration.
