The purpose of Bitcoin virus – to generate Bitcoins illegally

The image of Bitcoin virus

Bitcoin virus is a Trojan horse that hijacks devices in order to mine bitcoins using affected computer’s GPU and CPU. This cyber infection is also known as Bitcoin miner, Bitcoin mining or simply BitcoinMiner virus. Despite the variety of names, the purpose of the malware remains the same – to make money illegally.

For those who haven’t heard this term yet, we will say that Bitcoin is a virtual currency, which has appeared in 2008. However, it was started using more widely only in 2011. Currently, Bitcoins have already reached the circulation rate of more than 16 million at August 1st, 2017.[1]

There is no surprise that even the most reputable companies accept this currency. However, this currency is created not through a central monetary agency, but through the computers that perform CPU-intensive crypto calculations. Therefore, cyber criminals are always looking for new ways to take advantage of this feature by creating new versions of Bitcoin malware.

Bitcoin miner virus has several versions. The most known of them are called CPU Miner and Vnlgp Miner. Unfortunately, but you can hardly notice when your computer gets infected with it. According to experts, this malware tries to hide by trying to work only when a user is not using his/hers computer.

However, you can notice Bitcoin mining virus by monitoring your PC’s speed. It has been said that the usage of machine’s CPU grows up significantly when this virus infiltrates it, so don’t ignore such changes. What is more, the Trojan horse might also be capable of opening the backdoor or download other malicious programs.

If you notice system slowdowns or other suspicious activities, you should make sure that your computer is not infected. If you suspect something strange, you should check the computer with Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus. Security software will remove Bitcoin virus and stop its malicious activities.

The evolution of Bitcoin virus: ransomware variant hit the surface

Bitcoin ransomware is a specific version of Bitcoin virus, which can infiltrate a computer without user’s approval and then encrypt each of his/hers files. This threat has been noticed after encrypting the entire network of one medical center in the USA. However, it can also affect simple home users leaving them without their files.

Once it finishes the encryption of victim’s files, Bitcoin ransomware displays a warning message asking him or her to pay the ransom of 1.5 bitcoin. Please, do NOT pay it as you may end up with nothing! Keep in mind that you are dealing with scammers who can take your money from you and leave you without a special code needed to decrypt your encrypted files.

In this case, you should perform Bitcoin miner virus removal with Reimage and try to encrypt your files with the help of these tools: Photorec and R-studio. Keep in mind that dealing with cyber criminals is never an option!

Bitcoin mining malware has been noticed spreading in Russia

At the end of July 2017, it was reported that cryptocurrency mining malware infected 25% of computer users in Russia. [2] However, some sources report that this cyber infection may have infiltrated 30% of Russian computers.[3]

According to the official data, the majority of affected devices run in Windows OS. Meanwhile, Mac computers and iPhones haven’t suffered a lot from the virus.

The information about Bitcoin mining virus[4] was published authorities. However, security specialists and antivirus vendors claim that the scope of the attack is exaggerated.[5] Experts agree that in the past there were few issues with this malware, but not as huge as it is has been stated recently.

A representative from Kaspersky Labs, which is one of the main Russian antivirus vendors, claims that if such a huge attack were held, they would have noticed it. However, since the beginning of the year, only 6% of their customers have suffered from BitcoinMiner.[6]

Ways to get infected with malware

According to security experts, Bitcoin virus is mostly spread via Skype network, but it has also been noticed on other social networks, so beware about that. Typically, this virus relies on a spam message, which claims something like „this my favorite picture of you” and includes a malicious file. Of course, virus seeks to convince its victims to download the file onto their computers.

If you want to avoid it, stay away from such messages. Once victim downloads the “photo,” he not only lets malicious pieces inside the machine but allows the virus to connect PC to its command-and-control server.

Once inside and active, the virus turns the infected machine to the Bitcoin generator. However, it can also be designed to the virus, which steals banking details, records the keystrokes or downloads more malware on its target PC. That’s why you must perform Bitcoin virus removal as soon as it gets inside the PC.
