Detects the addition of suspicious file names or known potentially unwanted program artifacts to Windows Run registry keys, often used for persistence. The rule correlates registry modifications with potential installer process activity.
Detects instances where the Windows Remote Management host process (wsmprovhost.exe) is associated with the execution of specific suspicious files (config.toml, cplsupport.exe, or wtass.exe) within a short time window. This activity often indicates post-exploitation behavior or remote execution of secondary tools using WinRM.
Detects Toy Ghouls backdoor binaries (cplsupport.exe and wtass.exe) via known MD5 hashes or the presence of these files alongside a config.toml configuration file.
Detects files that present a valid PNG magic header at the start but contain embedded PostScript instructions. This pattern is commonly used to exploit vulnerabilities in image processing libraries like Ghostscript or ImageMagick, which may attempt to process the file as PostScript despite the misleading header.
Detects network activity (DNS queries, TLS SNI, and HTTP Host headers) directed towards domains ending in the .vu Top-Level Domain (TLD). This is associated with NovaCookies phishing infrastructure which utilizes these TLDs for malicious redirection or staging.
Detects anomalous OAuth redirection chains initiated from login.microsoftonline.com or accounts.google.com that target infrastructure identified as malicious .vu domains. This pattern is indicative of a consent-phishing campaign attempting to redirect users to malicious infrastructure.
Detects the creation of an NTUSER.MAN file followed by an update or creation of a registry run key (Run or RunOnce) on the same device within a 60-minute window. NTUSER.MAN is a mandatory user profile file that, when present, can be used to override user settings and persist malicious configurations or startup entries.
This rule detects the execution of a file named 'report.bin' and correlates it with subsequent network connections originating from the same process. This behavior is indicative of a potential C2 heartbeat or exfiltration activity involving a non-standard or obfuscated executable.
Detects FTP STOR commands associated with the transfer of files with a .pcap extension, which may indicate the exfiltration of captured network traffic from a network device or server.
Detects periodic outbound TLS connections over port 443 exhibiting beaconing behavior (5+ established connections with a non-empty SNI from a source host within 300 seconds), consistent with BridgeAgent malware C2 heartbeat/reverse-shell maintenance. Correlate with EDR detections of a process masquerading as /usr/bin/gnome-shell running as root and persisted via a fraudulent zabbix_agent.service.
