This rule monitors network traffic for communication with known malicious IP addresses (143.198.7.94 and 157.254.167.12) associated with the exploitation of NetScaler CVE-2026-88772 as part of the WHIPSHOT_SLAPSHOT campaign. These IPs are linked to staging, exploitation, and web shell backdoor installation activities.
This rule detects outbound network connections directed at a known IP address associated with Akira ransomware infrastructure. The rule specifically monitors for communication with 64.227.4.134, which has been identified as a C2 node utilizing GOST tunnels. This behavior is indicative of established C2 connectivity by Akira ransomware actors.

Detects network communication associated with the Rapuncel MaaS (Malware-as-a-Service) campaign, specifically identifying the Command and Control (C2) connection, GitHub Pages-based redirect chains, and subsequent delivery of large, suspicious ZIP archives containing renamed executable/system files.
Detects outbound network traffic from internal hosts to known IP addresses associated with Exvicy Malware-as-a-Service (MaaS) Command and Control (C2) or hosting infrastructure. This rule acts as an indicator of compromise (IOC) match to identify potential infected hosts communicating with malicious external servers.
Detects outbound network traffic and HTTP requests originating from the internal network destined for a known malicious infrastructure associated with 'Corp MDM'. The traffic includes C2 communication patterns, specific API URI paths, and potential login interactions on non-standard ports, consistent with phishing, malware delivery, or unauthorized administrative access.

Detects network communication to known SpiceRAT Command and Control (C2) IP addresses and DNS queries for known SpiceRAT-related domains. The rule identifies potential compromise by flagging outbound traffic or DNS resolutions associated with SpiceRAT infrastructure.
Detects network traffic associated with SilkParasite SpiceRAT malware, including direct IP connections, DNS queries for known malicious domains, and corresponding TLS SNI or HTTP Host header metadata indicating command-and-control (C2) activity.
Detects network communication with known Command and Control (C2) IP addresses associated with Phantom Stealer malware. This rule monitors both outbound connections from the internal network and inbound traffic from the identified malicious infrastructure.
Detects outbound connections to and inbound responses from known command-and-control infrastructure associated with the SpiceRAT malware, as part of the SilkParasite campaign. This rule monitors established TCP traffic on ports 80 and 443.
Detects network traffic to known Transparent Tribe (APT36) C2 IP addresses and DNS resolution attempts for their associated command and control domains. This rule monitors for communication with identified malicious infrastructure often used by the group for C2 activity.
Detects network communication with known Command and Control (C2) IP addresses associated with Phantom Stealer malware. This rule monitors both outbound connections from the internal network and inbound traffic from the identified malicious infrastructure.
Detects network communication with known Command and Control (C2) IP addresses associated with Phantom Stealer malware. This rule monitors both outbound connections from the internal network and inbound traffic from the identified malicious infrastructure.
Detects network communication with known Command and Control (C2) IP addresses associated with Phantom Stealer malware. This rule monitors both outbound connections from the internal network and inbound traffic from the identified malicious infrastructure.
Detects inbound network connections from known IP addresses associated with the StyleSmuggler malware distribution, which is used to inject malicious scripts into web applications.
