Blackbit Virus 🔐 (. Blackbit Files) — How to Remove?

Blackbit virus: what is known so far?

The scheme of renaming is the following: [contact_email][victimID]%filename%.BlackBit. In the process of encryption, a file entitled, for example, “report.docx” will be altered to “[][9ECFA84E]report.docx.BlackBit”.

In every folder with the encrypted files, a Restore-My-Files.txt text document will be found. It is a ransom money memo. Therein you can find information about the ways of contacting the racketeers and some other information. The ransom note most probably contains a description of how to purchase the decryption tool from the tamperers. You can obtain this decoding tool after contacting by email. That is it.

The Restore-My-Files.txt document coming in package with the Blackbit malware states the following:

!!!All of your files are encrypted!!!
To decrypt them send e-mail to this address:

How did Blackbit ransomware end up on my PC?

There are currently three most exploited methods for tamperers to have the Blackbit virus planted in your system. These are email spam, Trojan introduction and peer-to-peer file transfer.

If you access your mailbox and see letters that look like familiar notifications from utility services companies, delivery agencies like FedEx, Internet providers, and whatnot, but whose sender is unknown to you, be wary of opening those emails. They are very likely to have a harmful item enclosed in them. Thus it is even more dangerous to download any attachments that come with letters like these.

Another option for ransom hunters is a Trojan horse scheme². A Trojan is a program that gets into your PC pretending to be something legal. For instance, you download an installer for some program you need or an update for some program. However, what is unpacked reveals itself a harmful program that compromises your data. As the update file can have any name and any icon, you’d better be sure that you can trust the resource of the stuff you’re downloading. The optimal thing is to use the software developers’ official websites.

As for the peer file transfer protocols like torrents or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is finished.
