What is Centurion_Legion ransomware virus?

Description of Centurion_Legion virus

Another ransomware type virus has been created and released, and it is named Centurion_Legion. Examples of related viruses include Crysis ransomware, .xtbl virus, VegClass virus and a few others. Just like all these viruses, the new version encrypts all victim’s files and demands ransom. It also appends .centurion_legion_@_aol.com.xtbl file extension to encrypted files. Comparing Centurion_Legion malware to typical ransomware threats, it differs because it does not provide the cost of the decryption key, which can help the victim to restore files. It drops ransom notes (How to decrypt your files.txt and DECRYPT.JPG), which deliver a message from cyber criminals. They say that the victim has to contact crooks via two provided emails – the main one (mailrepa.lotos(@)aol.com), and the second one (goldman0(@)india.com) in case frauds do not respond in 48 hours. Then the victim has to wait for instructions on how to buy the decryption key and decrypt data using it.
Centurion_Legion malware leaves a threatening message

This virus is very dangerous as it can corrupt all your files. It uses very sophisticated encryption algorithms, and it combines even three of them. First of all, it encrypts data using the AES-246 cipher, and then it locks the key used for the decryption using RSA cryptography algorithm. What is more, this virus uses Cipher Block Chaining (CBC) mode, which is a technology that makes victim’s files non-decryptable if the user unsuccessfully attempts to decrypt data. Therefore, we do not recommend you to touch or do anything with your files because you might make them impossible to decode. IT experts are trying to discover a decryptor for this ransomware, so we suggest waiting. Meanwhile, you should remove the ransomware from the computer system, and you should do that using a professional malware removal program, for example, ReimageIntego. Our advice is not to mess with this virus by yourself because you might do more harm than good.

How does this malware spread?

This virus is distributed using spam e-mail campaigns, which means it tries to break into victim’s computer like Trojan horse. Cyber criminals conceal this threat and make it look like a safe file (usually a document), and send it directly to the victim via email. Do not be fooled; our advice is to stay away from emails that come from unknown senders, and it is very important not to open files attached to them, as this can immediately execute the virus.

We also suggest you to secure your computer in advance and install a good anti-malware program to keep the PC protected from spyware and malware attacks. Remember that you can end up installing a virus just by browsing through infectious Internet sites, and if you are not advanced enough to understand which websites are trustworthy and which ones are not, you can easily download malware into your PC without even realizing it. Bear in mind that crooks do their best concealing viruses and making them look like reliable files or programs, so be careful.

You can find instructions on how to backup your files in this post. Data backups come in useful when original data gets lost or corrupted.

If you did not take precautions earlier, and if this virus has encrypted all your records, we suggest you to remove the threat from the computer because now there is nothing much of what you can do.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
