What is CryptBot?

CryptBot is a malicious software that is classified as a Trojan, it is designed to steal passwords. It infects systems through the installation setup of a fake VPN program, it gets installed with another trojan-type malware called Vidar. Both trojans are designed to steal saved browser credentials and other information. These malicious programs can cause quite serious problems. Therefore, they should be uninstalled as soon as possible.

Once a fake VPN client called Inter VPN is downloaded, installed and executed, it infects a system with CryptBot and Vidar. It does it by using a AutoHotKey script which downloads executables of both CryptBot and Vidar from the bitbucket[.]org website (they could be downloaded from other sites as well). As we mentioned in the introduction, these malicious programs are designed to steal sensitive, confidential information. They can steal logins and passwords that are saved on browsers, cookies, cryptocurrency wallets, text files, take screenshots of a desktop, and so on. Cyber criminals could use stolen credentials to steal banking accounts, email and messaging clients, etc. They could misuse them to make fraudulent transactions, purchases, spread various malware, trick other people into sending them money, and so on. Stolen cryptocurrency wallets could be used to make transactions into wallets of cyber criminals, which means victims might lose a lot of money. Accessed text files, if contain sensitive details, might be misuses to generate revenue in similar ways as well. Having a system infected with such Trojans can lead to serious problems, for example, monetary loss, identity theft, various privacy issues, and so on. It is important to mention that CryptBot installs a legitimate VPN client (VPN Pro) so that victims would not suspect that two malicious programs are running in the background and stealing sensitive details.

There are many trojan-type programs that are designed to steal credentials and other sensitive information. Some examples are CStealer, Mispadu and Tinynuke. Typically, cyber criminals misuse stolen details to generate revenue in as much ways as possible. As a rule, victims experience financial loss, serious privacy issues, get their identities stolen, and so on. In one way or another, most of the times malware of this kind can be used to cause many and serious problems. Therefore, it there is a reason to believe that a system is infected with CryptBot, Vidar or any other malware, then it should be removed immediately.

How did CryptBot infiltrate my computer?

Research shows that this malware is advertised on a shady website where it is disguised as a legitimate VPN software. More examples of unreliable software download sources are Peer-to-Peer networks (torrent clients, eMule), third party downloaders, freeware download pages and free file hosting sites. As a rule, cyber criminals upload malicious files/programs that are disguised as legitimate. When people execute files that were downloaded from unreliable sources, they often cause installation of malware by themselves. Other popular ways to spread malware are by using spam campaigns, software 'cracking' tools and unofficial, fake software updaters. When cyber criminals spread malware via spam campaigns, they send emails that contain malicious attachments. In most cases they attach Microsoft Office, PDF documents, archive files like ZIP, RAR, executable files (like .exe files) and JavaScript files. Their main goal is to trick recipients into opening attached files. Once opened, they install some high-risk malware. Software 'cracking' tools are programs that supposed to activate paid, licensed software for free. In other words, to bypass its activation. Nevertheless, these tools, if used, often install malicious programs instead. Fake software updaters infect computers by installing malware instead of fixes, updates, or by exploiting bugs, flaws of outdated software that is installed on the operating system.

How to avoid installation of malware?

It can be avoided by not downloading files and programs from unofficial websites, through third party downloaders and other tools that we mentioned in the previous paragraph. The safest way to download it is by using official websites and direct links. It is also important to update installed software via implemented functions or tools that are designed by official software developers and not some third party updaters. Attachments (and web links) that are presented in irrelevant emails that are received from unknown, suspicious addresses should not be opened. Also, no third party programs should be trusted to bypass activation of licensed software. It is not legal to use such tools and they often infect computers with malware. And finally, operating systems should be regularly scanned with a reputable anti-spyware or antivirus software and all detected threats removed as soon as possible. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
