removal by Alice Woods - - | Type: Ransomware

Bitcoin ransomware — a crypto-virus which encrypts files and demands a ransom

Bitcoin ransomware
Scarab-Bitcoin is a file encrypting virus which locks up files using an AES chiper.

Bitcoin ransomware is a file encrypting virus which encodes data in order to gain revenue from the victims. It is also called Scarab-Bitcoin due to its belonging to the Scarab ransomware family. The virus often spreads via spam emails, bundles, or various malicious online sites. As all other ransomware-type viruses, this malware scans your computer’s hard drive and locks up files by using an AES cryptography[1]. After file encryption, a copy of a ransom note named “HOW TO RECOVER ENCRYPTED FILES.TXT’ is placed in each folder with files containing .Bitcoin extension. Cybercriminals are urging victims to contact them via GarryAxe@protonmail.ch and pay a certain price in Bitcoin to get a decryption tool in order to restore important data.

You will be the only one who can access that data and it will be highly protected from various cybercriminals. In this way, you will be able to avoid important data losses as it will remain safe.

Ransomware distribution techniques and avoiding tips

According to cybersecurity experts[2], ransomware can be distributed in many ways. The most common ones are:

  • Through spam emails. If you manage to get a letter which was automatically sent to the trash section – better delete it permanently. Various spams might contain harmful content such as links which once clicked and launched will start a virus installation into your computer system[3];
  • Software-bundles. A crypto-virus can hide within bundled freeware or third-party sources. As these programs or sites are provided by secondary hands, they might not be properly protected. So, better avoid downloading your software from unverified sites, but if you still want to keep on doing that – visit the “Custom/Advanced” section and carefully look through all downloading steps each time you make a download;
  • Malicious pages. Furthermore, ransomware spreads through various online websites such as online gaming, movie watching, and other familiar ones. In order to avoid damage that these kinds of sites may cause, visit only commonly known ones, which fit with the safety requirements;
  • All in all, the best way to avoid crypto-viruses is an antivirus program. Once installed and run properly, it takes care of your computer by scanning the whole system once in a while. Also, it will alert if something harmful is infiltrating and trying to damage systems.

Always remind yourself to pay attention whenever you download any programs. If you carefully browse the web and protect your computer by following the steps that are mentioned before, you will increase your security level significantly.
