🦑Exploitation of the Microsoft Exchange Vulnerability:

During the IR investigation, the Nocturnus Team was able to identify the initial compromise vector, in which the attackers exploited the recently discovered vulnerabilities in Microsoft Exchange server, which allowed them to perform remote code execution by exploiting the following CVEs: CVE-2021-27065 and CVE-2021-26858.

The attackers used this vulnerability to install and execute the China Chopper webshell via the following commands:

Once the attackers gained access to the network, they deleted the .aspx webshell file to cover their tracks:

cmd.exe /c del "C:\Program Files\Microsoft\Exchange Server\V15\\frontend\httpproxy\owa\auth\<file_name>.aspx"

Using the webshell, the attackers launched a PowerShell that was then used to download a payload from the following URL:

http://178.21.164[.]68/dwn.php?b64=1&d=nethost64C.exe&B=_AMD64,<machine_name>

The payload is then saved as C:\windows\zsvc.exe and executed. This is the start of the Prometei botnet execution:

The Prometei Botnet :

When the first module of the botnet, zsvc.exe, is executed, it starts to “prepare the ground” for the other modules:

It copies itself into C:\Windows with the name “sqhost.exe”
It uses Netsh commands to add a firewall rule that will allow sqhost.exe to create connections over HTTP
It checks if there is a registry key named “UPlugPlay”, and if present it deletes it
It sets a registry key for persistence as HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPlugPlay with the image path and command line c:\windows\sqhost.exe Dcomsvc
It creates several registry keys under SOFTWARE\Microsoft\Fax\ and SOFTWARE\Intel\support\ with the names MachineKeyId, EncryptedMachineKeyId and CommId, for later use by the different components for C2 communication.

Sqhost.exe:

Sqhost.exe is the main bot module, complete with backdoor capabilities that support a wide range of commands. Sqhost.exe is able to parse the prometei.cgi file from 4 different hardcoded command and control servers. The file contains the command to be executed on the machine. The commands can be used as “stand-alone” native OS commands (cmd commands, WMI, etc.) or can be used to interact with the other modules of the malware located under C:\Windows\dell
