How to remove Cerber3 virus and restore encrypted files

The new incarnation of famous Cerber virus was recently found in the Web. As always, the developers did their best, and this ransomware will be a problem for everyone who will pick it up. Currently there's no decent decryption tool, but if your data were encrypted by this virus, you should keep in touch and wait for the news.




Cerber3 virus and removal overview

Cerber3 crawls into the workstation through viral attachments in e-mail, and then straight starts to encrypt folders like Zepto ransomware. If you didn't manage to stop ransomware before it came in, then you will suffer losses. Cerber3 encodes all file types, including images, text, audio and video. Encryption takes from a few minutes to several hours. The process's duration may change depending on the workstation capacity and the amount of information stored on it. Swindlers demand you to give them 0.1754 BTC or almost 410 USD for your own data. At this version of Cerber, scammers use AES and RSA encryption algorithms, and it mean that it's impossible to directly decrypt the files.

How Cerber3 works

After the penetration, the virus changes user's wallpaper and creates three files. They are called "# HELP DECRYPT #.html", "# HELP DECRYPT #.txt", and "# HELP DECRYPT #.url". Html and txt files are just the messages with the demands of ransom, and the third one is the link to the payment website of Cerber3. if the victim won't pay in the mentioned time - the price will double. But it will be still 1.4 BTC, and it's not much, compared to the old versions of Cerber, where the price was 1.2 BTC from the start, and 2.4 if the user won't pay in time. Maybe, scammers just want to make the virus more effective, because many users just won't pay more than $1000 for any data, and rather will reinstall their OS. Anyway, we advise you not to pay. Firstly, user has no guarrantees of the data restore after the payment. Secondly - if the encrypted files aren't really very important - you can just wait until the proper decryption tool will be released.

The ransomware applies the strongest encryption algorithms that cannot be broken if the secret key is unknown. This means that there is only single 100% effective way to get back your files: to use the backup. If don't have backups - you can forget about your files, because you have no guarantee that hackers that stolen your data, won’t trick you again after receiving a ransom. You still have other possibilities to recover your files, but they cannot guarantee the success.

In this guide we have already told that If your workstation suffers from ransomware infection, you have just one completely safe way to restore files: to load the backup. All other manners which are described below cannot guarantee the outcome. The main advantage of backups is that they are stored on the separate drive, and aren't available for Cerber3's impact.

Other manners depend on the OS functionality, and their success depends on the complexity of the ransomware and the absence of skill. Anyway, in addition to backups, and the paying of ransom, there are two supplementary ways to get back your data. You might try the restore from shadow copies, or a special tool to recover the files. Decoding using the special decryptor is quite efficient, but unfortunately, such a program isn't created for now. But you can inspect the websites of the well-known AV program vendors who could develop such program. Manual restore via shadow copies can be made immediately. You may use the built-in functionality of Windows OS, but, we advise you the new programs that will make this job simpler. These tools are totally toll-free, and they were created by well-known IT-specialists. They are called Recuva and ShadowExplorer, and you might find all info on the official web-pages.
