MediaGet Monero Miner Virus – How Does It Infect

The attack, using a miner malware running via the process wuauclt.exe, named Dofoil, according to Microsoft reports has been conducted by forcing an update which features the Dofoil coin miner virus. This happens by a process, called poisoning, which attacks multiple computers, that have the MediaGet torrent program installed and running. This poisoning process was not detected by Microsoft researchers to come from torrents downloaded. It rather targets a process, called mediaget.exe. While the Dofoil miner was traditionally distributed via spammed e-mail messages, in this outbreak, started at March 6, 2018, news broke out that the virus targets the mediaget.exe process, which belongs to the MediaGet torrent program, often referred to by many as a PUA (Potentially Unwanted Application). At this point, no connection between MediaGet and Smoke Loader (Dofoil Coin Miner) is know, but the primary version for infection, on which the experts are working is that the crooks may have compromised the application in order to push their mining malware via the malicious executable.

Wuauclt.exe Monero Miner (Dofoil Coin Miner and Trojan) – Analysis

The wuauclt.exe miner virus is the type of malware that aims to use the resources of your computer system in order to mine for the cryptocurrency Monero at your PC’s expense. This procedure is initiated by the virus running the following malicious files in a forced update attack which makes them run as if they are miners. The files, which are malicious and related to the Dofoil miner are reported to have the following locations:

→ %TEMP%/my.dat
%AppData%\Local\MediaGet2\mediaget.exe
With SHA-1: 3e0ccd9fa0a5c40c2abb40ed6730556e3d36af3c)

The main infection has been reported by Microsoft researcchers to be caused by the following chain of activities being commenced:

1. The virus attacks the MediaGet torrent client by forcing update on the program somewhere between the 12th and 19th of February, 2018.
2. The distribution of the malware (actual infection with miner being ran) started on the already infected computers, several days later on the 1st of March, 2018.
3. This resulted in a mass outbreak of over 400, 000 computers being detected by Microsoft 5 days after the first infection, which started in 1st of March.

Te actual infection file, runs an update by a malicious Update Server, using the process mediaget.exe. This update drops and runs the update.exe malicious file with the following signature:

→ 513a1624b47a4bca15f2f32457153482bedda640

The update.exe file in it’s turn poisons the infected computer by extracting and executing the malicious script to the mediaget.exe process. The result is the mediaget.exe running in the background of your computer system and performing a so-called hashing operation that mines for the cryptocurrency Monero, by over-utilizing your Central Processor (CPU) and Video Card (GPU).

The mining process is conducted by dropping the following malicious executables, using the Trojanized mediaget.exe process:

  • My.dat – malicious executable.
  • Wuauclt.exe – the coin miner virus.

What the actual coin miner does is connect your computer to a cryptocurrency mining pool for the token Monero. This pool begins hashing operations by using your CPU and GPU’s power in order to generate Monero tokens. This process is connected to the virtual crypto wallet of the cyber-criminals and this is how they generate Monero at the expense of hundreds of thousands of users being infected so far who have the MediaGet torrent client installed on their computers. The bad news here is that if not removed in time, this cryptocurrency miner may even break down components from your computer by over-using them, so if you see any of the symptoms mentioned in this analysis, it is strongly reccomended that you immediately remove this miner from your computer.

If you see the following processes running without any specific authorization on your computer it is advisable to immediately end them as active tasks:

After you end those processes, we advise you to follow the removal instructuons underneath this article. They are specifically designed in order to help you to remove MediaGet Monero Miner from your computer either manually or automatically.
