RSA-4096 ransomware virus removal and decrypter

“All of your files were protected by a strong encryption with RSA-4096”

RSA-4096 denotes a standard of asymmetric encryption where both components of the public-private key pair are 4096 bits long. Such a high degree of entropy means that the objective of data decoding is hardly feasible unless the aforementioned private key is readily available. The crypto strength, unfortunately, has been misapplied by cybercrime actors over the past couple of years. Ransomware, a category of malicious code enciphering files belonging to infected users, turns this nonmalignant technology into a devastating tool for extortion. The only specimen that claims to harness this particular algorithm at this point is called TeslaCrypt.

Although all three iterations of said ransom trojan supposedly employ RSA-4096, it’s questionable how true-to-life such statements are. The only place where the standard is mentioned is in the ransom notes, which are documents that explain victims how to get their encrypted data back. However, analysis of several samples of this infection proves that it relies on a different mechanism, namely the AES cipher. This one is weaker, mainly because the encryption and decryption keys are identical. Security experts even managed to create an automatic decoder for some editions of the virus. And yet, affected computer users who seek assistance often judge the predicament by what they see in the ransom instructions, which say “All of your files were protected by a strong encryption with RSA-4096”. By the way, different versions of the TeslaCrypt hoax feature different titles of these documents. Howto_Restore_FILES is a widespread one. It’s available in HTM, TXT and PNG formats.

The ransomware under consideration also appends new extensions to the victim’s filenames. These allow determining the trojan variant and include .aaa, .abc, .ccc, .ecc, .exx, .micro, .mp3, .ttt, .vvv, .xyz, .xxx, and .zzz. In order to reinstate the defiantly withdrawn files, the user needs the unique private key, which is a subject of the imposed bargain with the racketeers. In other words, only a payment is grounds for decryption of the data. The bad guys ask for 2 Bitcoins or so. That’s a lot of money to pay for something you actually own. Anyway, do not panic after seeing the spooky-looking RSA-4096 alert. The ransom may be the sole option to restore information in some cases, but it may as well not be mandatory. The part below will advise you on the workarounds.

RSA-4096 ransomware automated removal and data recovery

Owing to an up-to-date database of malware signatures and intelligent behavioral detection, the recommended software can quickly locate the infection, eradicate it and remediate all harmful changes. So go ahead and do the following:

1. Download and install the antimalware tool. Open the solution and have it check your PC for PUPs and other types of malicious software by clicking the Start Computer Scan button

2. Rest assured the scan report will list all items that may harm your operating system. Select the detected entries and click Fix Threats to get the troubleshooting completed.

Data recovery toolkit to the rescue

Some strains of ransomware are known to delete the original files after the encryption routine has been completed. As hostile as this activity appears, it can play into your hands. There are applications designed to revive the information that was obliterated because of malfunctioning hardware or due to accidental removal. The tool called Stellar Data Recovery features this type of a capability and therefore it can be applied in ransom attack scenarios to at least get the most important files back. So use the app to get an idea of what data can be restored and let it do the recovery job. Here is a step-by-step walkthrough:

1. Download and install Stellar Data Recovery.

2. Open the application, select the types of recoverable files to look for, and click Next.

3. Choose the areas you want the tool to recover from and click the Scan button.

4. Having scanned the specified locations, the program will display a notification about the total amount of recoverable data. Close the dialog and click the Recover button. This will hopefully help you get some of your valuable files back.

Ransomware Prevention Tips

To avoid RSA-4096 ransomware and other file-encrypting infections in the future, follow several simple recommendations:

These techniques are certainly not a cure-all, but they will add an extra layer of ransomware protection to your security setup.

Revise your security status

Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup. Another benefit of using the antimalware tool is that it will keep ransomware threats from intruding on your computer further on.
