Tiggre Miner Virus – How Did I Get It

The main method of propagation that is used by the Tiggre Miner malware is believed to be via other infections, such as worms and the recently reported [wplinkpreview url=”https://sensorstechforum.com/remove-zusy-trojan/”]Zusy Trojan which downloaded the threat’s files directly onto the computers of victims.

Besides other malware, the Tiggre miner virus can also be detected to be uploaded as a legitimate program of some sort on third-party websites. These sites usually advertise the program as some sort of useful and legitimate tool, like:

  • A legitimate mining app.
  • Crackfix.
  • Patch.
  • Keygen.
  • Portable version of software.
  • Installer.
  • Driver and OS update.

Once victims are misled into downloading such programs, they may also receive the miner as a bonus to them, without their knowledge and consent.

Tiggre Miner – Activity

Once the Tiggre miner infects your computer, the virus stays silent via obfuscation techniques, while it performs it’s malicious activities on your PC. For starters, the malware drops an executable under a random name or a name that imitates a program. The malicious .exe is likely located in one of the commonly targeted Windows directories:

Once there, the miner may set multiple different registry entries so that the malicious file runs automatically when you boot Windows. For this, the malware creates value entries likely in the following sub-keys of the Windows Registry Editor:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

After dropping it’s payload and getting it to run the Tiggre miner connects to a remote miner pool. In this pool, the virus begins to transfer data from the mining operations it performs and begins the mining process. It enrolls your computer in a mining pool, where each dug up portion, called hash is sent and then when one block is gathered, all of the miner machines are credited their share of the profit.

But the dark difference here is that the cyber-criminals are the ones who get the profits, at the expense of your CPU and GPU overheating. And not only this, but your computer may start to become extremely slow as a result of this process and if the miners stay for longer periods of time on your PC, the end result of this is that some of it’s parts may even break down. So the more computers are enrolled, the bigger the data transfer of this miner virus:

But being unhealthy for your PC is not the biggest risk that is associated with this miner virus, mainly because of the fact that it may also come embedded with spyware. This means that it can also perform the following malicious activities on your PC:

  • Install keyloggers that track your keystrokes to steal passwords.
  • Take screenshots of your computer.
  • Download and run multiple instances of itself.
  • Steal files by copying them and uploading them to websites in the background.
  • Obtain financial information.

Remove Tiggre Miner from Your Computer

If you want to remove this miner virus from your PC, then you will need to firstly locate and stop It’s executable that is causing the mining activity. Usually, you can do this by entering Windows Task Manager and ending it as a process, but this is not always the case as some viruses hide their .exe processes very well. So do follow the manual removal instructions below if you know what are the files, related to this Trojan. Otherwise, if you want to be sure that this malware and all of the related virus files to it are gone from your computer system, we would advise you what most security experts would and that is to download and run a scan, using anti-malware software. Such program’s primary purpose is to try and detect and remove any possible malware and also ensure that your computer remains protected against infections in the future too.
