Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Known benign triggers

  • Because this port is in the ephemeral range, this rule may false under certain conditions, such as when a NATed web server replies to a client which has used a port in the range by coincidence. In this case, such servers can be excluded. Some applications may use this port but this is very uncommon and usually appears in local traffic using private IPs, which this rule does not match. Some cloud environments, particularly development environments, may use this port when VPNs or direct connects are not in use and cloud instances are accessed across the Internet.
