Detects network traffic matching a list of known malicious domains and IP addresses observed in CommonSecurityLog events, tightened to reduce noise from scanners/TI feeds, sinkholed infrastructure, and generic reused IPs by requiring domain-specific selectors and deduplicating repeated matches per host.
HBO Max ClickFix attacks IOC Hunt
Cortex XDR
Detects network activity (DNS queries or direct IP communication) associated with 'ClickFix' social engineering attacks targeting users under the guise of an HBO Max update or repair utility. The rule includes indicators for known malicious domains and IP addresses while incorporating filters to minimize false positives from security scanners, threat intel feeds, and automated crawlers by analyzing User-Agent strings and network source addresses.
Detects unauthorized processes accessing sensitive web browser files (login data, cookies, local state) from suspicious or non-standard paths. This is a common behavioral pattern for infostealers attempting to exfiltrate user credentials and browser session tokens.
This rule detects attempts to exploit a path traversal vulnerability (CVE-2024-21762) in FortiOS SSL-VPN by monitoring for malformed GET requests targeting the /remote/fgt_lang endpoint. The rule also tracks successful exploitation by identifying HTTP 200 responses containing Linux password file patterns (root:x:0:0:), indicating potential remote file disclosure.

Detects outbound network traffic from internal hosts to known MeshCentral Command and Control (C2) infrastructure. MeshCentral is legitimate remote monitoring and management (RMM) software that is frequently abused by threat actors to maintain persistent remote access to victim environments. This rule monitors for established TCP connections on specific ports associated with MeshCentral C2 nodes.

This rule detects potentially unauthorized access or large-scale extraction of sensitive RADIUS server configuration and credential databases. It monitors for common database management tools and commands used in conjunction with RADIUS-specific paths, particularly when executed by unexpected processes, during off-hours, or in a manner indicative of bulk data export.

Detects attempts to delete, truncate, or overwrite critical system logs and user command history files (such as /var/log/auth.log, syslog, or .bash_history) on Linux systems using common utilities like rm, shred, and truncate. The rule includes exclusions for legitimate system maintenance processes like logrotate and cron.
