Detects network connections from common web browsers to domains associated with the BragJack threat actor infrastructure. This activity potentially indicates an end-user accessing malicious sites used for credential harvesting, malware delivery, or C2 communication.
Detects network connections from common web browsers to domains associated with the BragJack threat actor infrastructure. This activity potentially indicates an end-user accessing malicious sites used for credential harvesting, malware delivery, or C2 communication.
This rule identifies successful network connections from local devices to a predefined list of known malicious IP addresses within the last 7 days. Such connections often indicate active communication between a compromised endpoint and adversary-controlled infrastructure.
Detects network connections from common web browsers to domains associated with the BragJack threat actor infrastructure. This activity potentially indicates an end-user accessing malicious sites used for credential harvesting, malware delivery, or C2 communication.
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 instances where users successfully access websites categorized by FortiGuard as 'Artificial Intelligence Technology' without being blocked by the web filtering policy. This rule is intended to support organizational AI governance, data loss prevention, and intellectual property protection policies.
Detects instances where Zscaler web security logs identify malware, threats, or viruses, specifically flagging users and destination hosts involved in these blocked or allowed security events.
Detects high or critical severity Data Loss Prevention (DLP) alerts triggered by the Zscaler NSS platform. The rule identifies web traffic involving sensitive information categories such as Personally Identifiable Information (PII), financial data, or source code, which have been either allowed or blocked by Zscaler policy.

FortiGate Allowed RDP Connection
Cortex XDR
Detects network traffic identified by FortiGate as Remote Desktop Protocol (RDP) that has been explicitly permitted (Accept action) by the firewall policy. This rule monitors for successful packet flow through the firewall, providing visibility into potential lateral movement paths via RDP.
Detects Zscaler ZIA logs identified as Advanced Threat Protection events, specifically targeting URL categories like Phishing and WebSpam, or traffic classified as Advanced Security Risk. The rule aggregates these events by user to identify potential malicious activity, flagging sessions where threats were allowed as higher severity.

Detects instances where Zscaler web security logs identify malware, threats, or viruses, specifically flagging users and destination hosts involved in these blocked or allowed security events.
Detects FortiGate web-filter events where access to selected high-risk or security-relevant FortiGuard categories was not blocked. The monitored categories include malicious websites, phishing, spam URLs, Dynamic DNS, peer-to-peer file sharing, and crypto-mining destinations. The event should be investigated according to the specific category and destination context.
