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.

1202,1200 (repeat)
1202,1200 (repeat)
1398, 1396
1202, 1200 (repeat)
1202,1200 (repeat)
1202,1200 (repeat)

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
Type: PE32
MD5: ff30fbee3724d80dcb9471c0b553c99a
Vuln ID: MVID-2021-0240
Dropped files: svchostc.exe, svchosts.exe, surte.exe

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