Xevan Coin Miner – How Did I Get It?

The Xevan Coin Miner Trojan may infect your computer system via a variety of ways, the main ones of which are believed to be via:

  • E-mails that may carry malicious e-mail attachments embedded within them.
  • E-mails carrying malicious web links.
  • Malicious files, pretending to be installers of drivers, patches, cracks and other programs.
  • Malicious web links that may be sent to the victim via the social media, chats or other forms of online communication.

If the Xevan coin miner is spread via malicious files, that are usually uploaded online, they may pose as:

  • Setups of programs.
  • Key generators.
  • Game cracks or patches.
  • Software license activators.

In case Xevan is spread via e-mail, the cyber-criminals may send you a message that only makes it appear as if it’s being sent to you from a big company, like DHL, PayPal, eBay and many other big companies. The e-mails often pretend that they contain legitimate types of files from the likes of invoices or other types of documents which may be convincing enough for the user to open them.

Xevan Coin Miner Trojan – Activity

Xevan Coin Miner is the type of malware which may download it’s malicious payload after having infected your computer system. This may ultimately result in the malware becoming active while you do not even notice it. It’s malicious files may be of the following file types:

→ .exe, .tmp, .dll, .vbs, .cmd

As soon as these files are dropped on the computer of the user, the miner malware may have them residing in the following Windows directories:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

When the Xevan Coin Miner drops it’s files, the virus may create mutexes on your computer and modify it’s Windows registry editor by adding Windows registry sub-keys with custom registry values in them that enable it to act as an administrator on your computer. In addition to this, the Xevan Coin Miner may also run a background process which may be with a suspicious name and location. The process may not overload your CPU, but instead it may heavily overuse your PC’s Video Card for it’s mining activities, which may increase the side heat of it, and even amortize it to a level where you may no longer be able to use it with the same quality as it was before that. But this may happen only if the miner is left for longer periods to run on your computer.

In addition to this, the Xevan miner is also the type of malware which is oriented only in the cryptocurrencies that are mineable using the Xevan algorithm for mining. These are the following as far as we know:

BitSend – BSD
Solaris – XLR
Nanucoin – NNC
Northern Coin – NORT
Amsterdam Coin – AMS
XHIMERA – XHM
B-Hash – HASH

When the Xevan miner is installed on your computer and ran, you may not notice it. But the symptoms of your PC becoming slow and freezing at times may appear eventually, especially if you are watching a movie or playing a video game. This is because the Xevan coin miner is aimed at one thing only – using your GPU’s architecture and power in order to perform the so-called hashing procedures. These hashing actions are basically performing complex calculations in order to generate coins from the list above. When a block of hashes is calculated by the Xevan coin miner virus on your PC, the reward, which usually comes from a mining pool, the virus connects you to, is debited to the account of the hackers who have infected your PC with the virus.

All of this is done at the expense of your GPU’s condition, which rapidly worsens due to overusage from the miner. And if that is not enough to cause you headaches, the Xevan miner may also be a part of a Trojan infection. As we all know, Trojans tend to be invasive and they often perform set of malicious activates that make them “the remote control” of the cyber-crooks to your computer. Here is what the Xevan Trojan may be capable of doing on your PC, besides it’s primary mining activities:

  • It may download and install other malware on your PC.
  • The Xevan miner may also download and install updates or copies of itself as insurance in case you remove it.
  • It may stop your internet connection and start it again.
  • Delete files and system objects from your computer.
  • Take screenshots of your screen and send them live to the hackers.
  • Take pictures from your web cam or record video.
  • Log the keystrokes you type.
  • Steal passwords and files from your PC.
  • Steal financial information.

These reasons are more than enough for you to focus on removing the Xevan cryptocurrency miner from Windows and making sure it doesn’t come back.
