If you have received a threatening message claiming "All your files were encrypted" or "All your files were protected by a strong encryption with RSA-4096," it means your computer was infected with a malicious PC virus, known as ransomware. This particular type of computer threats takes victim's files hostage by encrypting them and urges the victim to pay up. The mention of the RSA-4096 key indicates that you are dealing withTeslaCrypt virus, one of the most dangerous ransomware variants in the wild.
RSA-4096 Ransomware locks all files including music, videos, documents, photos, and other relevant records stored on the compromised PC. This malicious software is programmed to detect particular file types (judging by file extensions) and encrypt them using the RSA-4096 encryption algorithm. Sadly, the message this virus sends is not a joke. You cannot recover your data so simply after this virus strikes. They are encrypted with unique keys, and unless you have them, you cannot decrypt the encrypted data. Unfortunately, cyber criminals remove these keys from the computer after the malicious encryption procedure is done and store them on their own servers. After that, you will find several ransom notes dropped on the PC in various locations. These notes are titled RECOVER[random symbols].txt, Howto_Restore_FILES.txt or How_Recover+(random symbols).txt. They may also come in HTML and PNG formats.
What this virus wants you to do?
Of course, the idea of losing all computer files all of sudden is scary, and the developers of TeslaCrypt know this very well. This is exactly what they aim for - they seek to scare the user. The ransom notes RSA-4096 malware leaves inform the user that files were encrypted and that they can be decrypted only with a unique RSA-4096 decryption key, which is hidden in a "secret" server. Crooks even ironically mention that user can have two options to choose from - wait for a miracle to happen or buy the decryption key from them and recover corrupted files. These frauds demand ransom worth 500$, but the price may vary. The user must transfer the payment in Bitcoins for scams using Tor (anonymous communication software) so that cyber criminals could not be tracked and punished by legal authorities.
Crooks urge the victim to pay the ransom as soon as possible; otherwise, the price will double. Unfortunately, in many cases, frauds just take victim's money and leave him/her with encrypted files without helping him/her with the decryption. We also do not recommend you to pay up because this will encourage cyber criminals to continue their fraudulent activities. If you have decided not to pay up, we strongly recommend you to remove RSA-4096 malware from your computer using Reimage anti-malware. Although RSA-4096 bit encryption is very hard to crack and computer experts still cannot find 100% effective antidote for TeslaCrypt, some RSA-4096 decryption tools have already been created - you can find their download links on page 2.
How cyber criminals distribute RSA-4096 ransomware?
To spread this ransomware, cyber criminals render phishing attacks and exploit kits. The majority of victims state that they received a ransom note just a couple of minutes after they opened an email attachment notifying about pre-paid purchases, loans, taxes, and other official information. Spam email infections are well known already, but, nevertheless, people's curiosity is a natural thing that allows such cyber threats as the RSA-4096 encryption virus spread very successfully. Therefore, whenever you receive a doubtful looking email message, do not rush to open it. First of all, verify its sender, theme, presence/absence of mistakes, and other features. If at least a slightest suspect rises, you'd better report the message for spam. Last, but not least, you should also avoid clicking on the pop-up ads offering to update certain software or check the system for viruses online. Such messages are typically fake and may contain Trojan infections that spread RSA-4096 or other cyber infections.
Can you remove RSA-4096 ransomware manually?
Technically, there is a way to remove RSA-4096 virus manually. We will provide the guide at the end of this post. Nevertheless, manual removal of such dangerous cyber threats is recommended to be performed by professional technicians only, because instead of removing infected files, you may delete important system files and cause the system crash. That is why we strongly recommend you to perform RSA-4096 removal with a powerful anti-malware software, such as Reimage.
IMPORTANT. Before you try to decrypt RSA-4096, you must remove the virus and its files from your computer. After that, you can recover your files from a backup (if you had one), but if you didn't, we suggest you to try these RSA-4096 file recovery tools: TeslaCrypt decryption tool or this TeslaCrypt decryptor.
