The Anthraxbulletproof virus falls within the Chaos ransomware family. Malware of this type encrypts all userâs data on the PC (images, documents, excel tables, audio files, videos, etc) and appends its specific extension to every file, leaving the read_it.txt files in every folder which contains the encrypted files.
Anthraxbulletproof virus: what is known so far?
âïž A strictly accurate denomination for the Anthraxbulletproof would be âa Chaos family ransomware infectionâ.
Anthraxbulletproof adds its own .Anthraxbulletproof extension to every fileâs name. For instance, a file entitled âphoto.jpgâ will be turned into âphoto.jpg.Anthraxbulletproofâ. Just like the Excel file named âtable.xlsxâ will be changed to âtable.xlsx.Anthraxbulletproofâ, and so on.
In each directory containing the encrypted files, a read_it.txt text document will be created. It is a ransom money note. It contains information about the ways of paying the ransom and some other information. The ransom note usually contains instructions on how to purchase the decryption tool from the Anthraxbulletproof developers. That is it.

How did Anthraxbulletproof ransomware end up on my PC?
There is a huge number of possible ways of ransomware infiltration.
Nowadays, there are three most popular ways for hackers to have ransomware acting in your system. These are email spam, Trojan injection and peer-to-peer file transfer.
If you open your inbox and see letters that look just like notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose âfromâ field is strange to you, be wary of opening those letters. They are very likely to have a malicious item attached to them. So it is even riskier to open any attachments that come with emails like these.
As for the peer-to-peer file transfer protocols like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So youâd better be using trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded objects with the antivirus as soon as the downloading is finished.
How to remove the Anthraxbulletproof virus?
It is crucial to inform you that besides encrypting your data, the Anthraxbulletproof virus will most likely install the Azorult Spyware on your computer to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware3 can derive your logins and passwords from your browserâs auto-filling data.
Often criminals would decode several of your files to prove that they really have the decryption program. As Anthraxbulletproof virus is a relatively recent ransomware, anti-malware developers have not yet found a method to undo its work. Nevertheless, the anti-ransomware tools are frequently upgraded, so the solution may soon arrive.
Of course, if the evildoers succeed in encoding someoneâs critical data, the desperate person will probably comply with their demands. Nevertheless, paying a ransom gives no guarantee that youâre getting your blocked information back. It is still dangerous. After getting the ransom, the racketeers may send a wrong decryption key to the injured party. There were reports of hackers just disappearing after getting the ransom without even bothering to reply.
The optimal safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external drive. Obviously, that might be insufficient. The most important thing could be that file you were working on when it all started. But at least it is something. It is also wise to scan your drives with the anti-malware utility after the system is rolled back.
There are other ransomware products, besides Anthraxbulletproof, that work similarly. For instance, Nuis, Powd, Bowd, and some others. The two main differences between them and the Anthraxbulletproof are the ransom amount and the encoding method. The rest is the same: files become encoded, their extensions changed, ransom notes are found in every folder containing encoded files.
Some lucky victims were able to decrypt the arrested files with the help of the free tools provided by anti-ransomware developers. Sometimes the criminals mistakenly send the decryption key to the wronged in the ransom note. Such an epic fail allows the user to restore the files. But naturally, one should never expect such a chance. Make no mistake, ransomware is a tamperersâ tool to lay their hands on the money of their victims.
How Ńan I avoid ransomware injection?
Anthraxbulletproof ransomware has no endless power, neither does any similar malware.
You can protect yourself from its infiltration taking three easy steps:
- Never open any letters from unknown mailboxes with strange addresses, or with content that has likely no connection to something you are waiting for (how can you win in a lottery without participating in it?). In case the email subject is more or less something you are waiting for, check all elements of the suspicious email carefully. A fake email will always contain a mistake.
- Do not use cracked or untrusted software. Trojan viruses are often spreaded as a part of cracked products, most likely as a âpatchâ preventing the license check. But potentially dangerous programs are very hard to distinguish from reliable ones, because trojans may also have the functionality you need. Try to find information on this software product on the anti-malware forums, but the optimal way is not to use such programs at all.

FAQ
đ€ How can I open â.Anthraxbulletproofâ files?Are the â.Anthraxbulletproofâ files accessible?
Negative. That is why ransomware is so frustrating. Until you decode the â.Anthraxbulletproofâ files you will not be able to access them.
đ€ The encrypted files are very important to me. How can I decrypt them quickly?
If the â.Anthraxbulletproofâ files contain some really important information, then you probably have them backed up. In case you havenât, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. The rest of the methods require patience.
đ€ What to do if the Anthraxbulletproof ransomware has blocked my computer and I canât get the activation key.
đ€ What can I do right now?
Many of the encrypted files might still be at your disposal
- If you sent or received your important files via email, you could still download them from your online mail server.
- You might have shared photographs or videos with your friends or relatives. Simply ask them to give those images back to you.
- If you have initially downloaded any of your files from the Web, you can try downloading them again.
- Your messengers, social media pages, and cloud disks might have all those files as well.
- It might be that you still have the needed files on your old PC, a portable device, phone, memory stick, etc.
USEFUL TIP: You can employ data recovery programs6 to get your lost data back since ransomware encrypts the copies of your files, deleting the original ones. In the tutorial below, you can see how to recover your files with PhotoRec, but be advised: you wonât be able to do it before you eradicate the ransomware itself with an antivirus program.
Also, you can contact the following governmental fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sĂ©curitĂ© des systĂšmes dâinformation;
- In Germany: Bundesamt fĂŒr Sicherheit in der Informationstechnik;
- In Ireland: An Garda SĂochĂĄna;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
