Bulwark Ransomware 🔐 (. Bulwark File) — Removal Guide

What is Bulwark virus?

Bulwark will append its own .bulwark extension to every file’s name. For example, a file named “photo.jpg” will be altered to “photo.jpg.bulwark”. In the same manner, the Excel table with the name “table.xlsx” will end up as “table.xlsx.bulwark”, and so on.

In every folder with the encrypted files, a !-Recovery_Instructions-!.html text file will be found. It is a ransom money memo. Therein you can find information on the ways of paying the ransom and some other remarks. The ransom note most probably contains a description of how to buy the decryption tool from the ransomware developers. That is it.

In the image below, you can see what a folder with files encrypted by the Bulwark looks like. Each filename has the “.bulwark” extension appended to it.

How did Bulwark ransomware end up on my PC?

There are currently three most exploited ways for hackers to have ransomware acting in your digital environment. These are email spam, Trojan infiltration and peer networks.

If you open your mailbox and see letters that look like familiar notifications from utility services providers, delivery agencies like FedEx, Internet providers, and whatnot, but whose sender is strange to you, be wary of opening those letters. They are most likely to have a malicious file enclosed in them. So it is even riskier to open any attachments that come with letters like these.

Another thing the hackers might try is a Trojan virus scheme³. A Trojan is an object that infiltrates into your PC disguised as something different. Imagine, you download an installer for some program you need or an update for some service. However, what is unpacked reveals itself a harmful agent that encrypts your data. As the installation package can have any name and any icon, you have to make sure that you can trust the resource of the stuff you’re downloading. The best way is to trust the software companies’ official websites.

As for the peer-to-peer networks like BitTorrent or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is finished.
