Lsmma.exe Miner Virus – More Information
How did the Lsmma.exe miner sneak into your system? In most cases, miners use malicious files that can be downloaded from infected email attachments, torrent websites, and freeware download websites. These types of malicious files can use exploits in Windows to infect your system. That is why it is extremely important to apply security patches and keep your system and programs up-to-date.
Files such as Lsmma.exe may be sent to you via e-mail in the form of fake documents, invoices, receipts. These files could also be uploaded on sites for free downloads, such as fake cracks, patches, portable programs, etc. Note that these methods are widely deployed for the quiet distribution of Trojan horses across computers.
Once the Lsmma.exe file has been installed on your system, the Trojan that is causing the miner process could drop files in the following Windows system directories:
- %AppData%
- %Local%
- %LocalLow%
- %Roaming%
- %Temp%
The Lsmma.exe process is related to a Bitcoin mining virus. The process may run as administrator, as the virus behind it could take over the admin rights of your computer. Then, the malicious process could execute the cryptocurrency miner, which will exploit your CPU and GPU (Central Processor and Video Card) in order to mine for cryptocurrencies, which leads to the overheating of your computer and its worsened performance.
In most cases, cybercriminals who are running mining operations such as the Lsmma.exe virus miner are aiming at Monero and Bitcoin but other cryptocurrencies (shortly known as altcoins) may be targeted as well. The mining process includes connecting your computer to a so-called cryptominer (cryptocurrency mining) pool. These pools are a virtual network of computers that all combine their mining power to obtain cryptocurrencies for their operators. Their sole purpose is to infect as many computers as possible for larger profits.
This is how a miner pool can be pictured:
