Description

A trojan miner for Windows OS written in C++. Depending on the type of coins being mined, it can be based on the code of either XMRig or ETHmine. The miner is injected into explorer.exe by its loader Trojan.BtcMine.3767 via the SetContextThread function. When the process is created, its Shellinfo variable in the RTL_USER_PROCESS_PARAMETERS structure accepts a string containing the miner configuration, encrypted with AES CBC, and additionally encoded with base64. The key is UXUUXUUXUUCommandULineUUXUUXUUXU, and the initialization vector is UUCommandULineUU. After decryption, the miner configuration looks like this:

#drweb

In addition to the settings inherited from XMRig, Trojan.BtcMine.2742 accepts the settings provided by its loader, compiled using the SilentCryptoMiner project.

--cinit-winring= Contains a path to the previously created winring file
--cinit-remote-config= Contains a link to download miner settings every 100 seconds
--cinit-stealth-targets= Lists the applications that, when launched, will cause the miner to free up video memory and RAM
--cinit-stealth-fullscreen This flag tells the miner to pause mining when an application is running in full screen mode. The SHQueryUserNotificationState function performs the verification
--cinit-kill-targets= Kills the specified processes when they are detected
--cinit-api= Contains the URL of a web panel used to monitor and control the miner
--cinit-version= Contains the SilentCryptoMiner version
--cinit-idle-wait= ПIf no user activity is detected within the specified time, the miner's maximum CPU utilization will change
--cinit-idle-cpu= Maximum CPU utilization by the miner if no user activity is detected
--cinit-idle-gpu= Maximum GPU utilization by the miner if no user activity is detected
--cinit-max-gpu= Maximum GPU utilization when IDLE mode is turned off
--cinit-id= Contains the name of the created mutex
--cinit-algo= Sets the mining algorithm

Curing recommendations

  1. If the operating system (OS) can be loaded (either normally or in safe mode), download Dr.Web Security Space and run a full scan of your computer and removable media you use. More about Dr.Web Security Space.
  2. If you cannot boot the OS, change the BIOS settings to boot your system from a CD or USB drive. Download the image of the emergency system repair disk Dr.Web® LiveDisk , mount it on a USB drive or burn it to a CD/DVD. After booting up with this media, run a full scan and cure all the detected threats.
Download Dr.Web

    • Load your smartphone or tablet in the safe mode (depending on the operating system version and specifications of the particular mobile device involved, this procedure can be performed in various ways; seek clarification from the user guide that was shipped with the device, or contact its manufacturer);
    • Once you have activated safe mode, install the Dr.Web for Android onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
    • Switch off your device and turn it on as normal.
