InfoSec Handlers Diary Blog

Starting Sunday (22 Jan 17), there was a huge spike this week against TCP 5358. If anyone has logs o r packets (traffic) that might help identify what it is can submit them via our contact page would be appreciated. This is a snapshot as to what was reported so far this week in DShield.

Update 1

We received information this port could be use by Web Service on Devices API (WSDAPI)[2] or potentially various version of DVR's and NVR's.
