What's Up With All The Port Scanning Using TCP/6000 As A Source Port?
We here at the SANS ISC always appreciate all the feedback from our readers concerning
Internet anomalies. One such anomaly that caught my attention was a reader pointing out
some port scans that happened to target irregular Internet Protocol numbers.
While looking through my own firewall logs for similar activity, I was surprised to see a
large number of log entries involving unsolicited TCP packets that use TCP Port 6000 as
the source port.
The traffic brings back memories of the W32/Dasher worm from 2005 that had a similar
signature in its scanning (propagation) traffic where a constant TCP source port of
6000 was also used... but that was almost 5 years ago!
Has anyone had similar experiences with this type of port scanning traffic? I welcome
your comments and feedback.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
