Detects anomalous bulk GET requests directed at Cisco SD-WAN (vManage) REST API endpoints, specifically targeting topology information, device lists, and configuration templates. This pattern of activity is indicative of reconnaissance or exfiltration attempts against the SD-WAN fabric management interface.
Detects non-Steam processes accessing Steam configuration files (e.g., config.vdf, loginusers.vdf, ssfn files) and reading Steam-related registry keys. This behavior is indicative of infostealer malware attempting to hijack Steam sessions or exfiltrate account configuration data.
Detects SNMP bulk walk used to collect network device configurations
This rule detects attempts to access network device configurations via SNMP (UDP port 161) by looking for the string "public" in the UDP payload. A threshold of 10 occurrences within 30 seconds from the same source IP is set to trigger an alert, indicating a potential network scan or reconnaissance activity targeting SNMP with a common community string.
