Comprehensive IOC sweep across endpoint file/process/network telemetry for the full set of known SilkParasite/SpiceRAT/NodeEdgeRAT/NomadRAT/BloodAlchemy infrastructure indicators reported by Hunt.io and Security Affairs: all listed C2/decoy/certificate-hosting IPs, all listed spoofed/infrastructure domains, and known file/certificate hashes (SHA256, SHA1).
Detects outbound network connections from devices to specific suspicious domains identified in the detection logic. This rule monitors for connections to 'ns2.asiainfo.it.com' and 'www.wordcheck.info', which may be indicative of malware communication, command and control, or malicious web activity.
This rule detects network connections from internal devices to known SpiceRAT Command and Control (C2) infrastructure IPs. The detection filters for successful connections on common ports (80, 443) that meet a volume threshold, indicating potential ongoing beaconing or communication with malicious infrastructure.
Detects periodic outbound HTTP POST requests consistent with C2 beaconing behavior associated with the Latrodectus malware. The rule identifies multiple POST requests occurring within a 10-minute window, a pattern often used by Latrodectus for command-and-control heartbeats.
Detects outbound TCP traffic originating from internal hosts to known command and control infrastructure associated with the SilkParasite campaign and the SpiceRAT malware family.
Detects Remote Desktop Protocol (RDP) traffic occurring over non-standard high ports (64350, 64330, 65535, 65111, 61256), which is indicative of SilkParasite C2 activity or potentially malicious lateral movement attempting to bypass standard port monitoring.
Detects outbound network connections from internal hosts to known Autonomous System Numbers (ASNs) associated with SilkParasite infrastructure, which are often used to host malicious command-and-control or staging assets.
Detects network activity associated with the SilkParasite actor's NodeEdgeRAT malware, including DNS queries, TLS SNI, HTTP Host headers, and direct IP connections to the identified command-and-control infrastructure 'hoster-kg.com'.
Detects network traffic and DNS queries associated with the SilkParasite command-and-control (C2) infrastructure. This rule monitors for established RDP-over-TLS connections using non-standard, high-numbered ports and identifies associated DNS lookups for known C2 hostnames.
Detects potential ClickFix-style social engineering attacks where a victim is prompted to execute an encoded PowerShell command (often via copy-paste into a terminal). The rule specifically monitors PowerShell processes initiated by shell environments (explorer.exe, cmd.exe, or WindowsTerminal.exe) that execute encoded, hidden scripts to perform multiple suspicious network requests for files (e.g., .zip, .enc, .bin) from non-standard domains.
This rule detects instances where a process associated with a known StealC command-and-control (C2) IP address subsequently spawns a hidden cmd.exe instance. It correlates network connections to known malicious infrastructure with the creation of hidden command shells within the same device session, specifically looking for common parent processes like web browsers or system utilities.
Detects network traffic to GitHub API endpoints that matches patterns indicative of RUSTYSHADE malware communicating with a private repository for command and control. The rule specifically looks for access to repository content paths related to commands, results, heartbeats, screenshots, or information files, coupled with the inclusion of an Authorization token in the HTTP header.
This rule detects the execution of 'DriverInstaller.exe' (either by filename or a known malicious SHA256 hash) that subsequently initiates network connections to GitHub domains. This behavior is indicative of potential malicious activity, such as downloading secondary payloads, command-and-control communication, or beaconing from a suspected rogue or masquerading driver installation utility.
Detects potential C2 activity associated with MQTTDoor or MatrixDoor malware by monitoring suspicious network traffic patterns. This includes unauthorized processes connecting to MQTT brokers (hivemq.com), non-chat applications interacting with a Matrix homeserver, and geo-location lookups (ip-api.com) occurring shortly after process execution.
Detects the ClosedQuorum 'unhook' evasion technique where a process patches ntdll's EtwEventWrite to suppress ETW telemetry, occurring within a 5-minute window of the same process initiating outbound network connections to known LLM C2 provider APIs or Discord webhooks used for AI-arbitrated decision cycles.
Detects the ClosedQuorum 'unhook' evasion technique where a process patches ntdll's EtwEventWrite to suppress ETW telemetry, occurring within a 5-minute window of the same process initiating outbound network connections to known LLM C2 provider APIs or Discord webhooks used for AI-arbitrated decision cycles.
This rule detects activities associated with the AMOS (Atomic macOS Stealer) malware family by monitoring for known malicious file hashes on endpoints and network communication with domains linked to its command-and-control infrastructure.
This rule detects network traffic indicative of the SCKIT MemTensor worm establishing a command-and-control (C2) beacon. The detection identifies TLS connections where the Server Name Indication (SNI) matches a specific pattern of a 12-character hexadecimal string followed by .skyleen.fr.
This rule detects network traffic indicative of the SCKIT MemTensor worm establishing a command-and-control (C2) beacon. The detection identifies TLS connections where the Server Name Indication (SNI) matches a specific pattern of a 12-character hexadecimal string followed by .skyleen.fr.
This rule detects network traffic indicative of the SCKIT MemTensor worm establishing a command-and-control (C2) beacon. The detection identifies TLS connections where the Server Name Indication (SNI) matches a specific pattern of a 12-character hexadecimal string followed by .skyleen.fr.
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.
