RSA-4096 is a version of well-known TeslaCrypt (AlphaCrypt, Cryptesla) ransomware
The exploit kit, responsible for your files encryption, is hosted on a corrupted website. Such a website may be intentionally designed for the malicious purpose or its otherwise benign code could be cracked and modified by the attacker. That does not really matter for a victim: one way or another, the exploit executes its payload and drops the backdoor trojan. The trojan may be detected under a variety of names.
The backdoor so injected proceeds with fulfilling its tasks, of which the most dangerous is the ransomware invasion. That is, RSA-4096 virus has been observed to enter computer systems via malicious routine arranged by trojan horse. The campaign has been ongoing since April 2016.
The strain under review deploys RSA encryption campaign transforming data on the host machine into unreadable and unrecognizable format. To complicate the scam investigation, the ransomware lingers approximately one hour after its introduction. IT security experts suppose the measure aims at concealing the infection vector. That is, the ransomware lingering span creates a gap between the invasion and the encryption so that the victims would not associate the attack with the website that has exploited system vulnerabilities to drop the virus.
RSA-4096 informs its victims on the attack with its ransom note. It generates quite typical message. A victim is prompted to pay the ransom in bitcoin currency, the amount is approximately USD 500. A dedicated TOR channel is to be established for each transaction. That ensures ultimate anonymity of the parties to the transaction.
Apart from executing the data encryption payload, the rogue is notorious for stealing data from your PC. It is known to crack bitcoin wallets and extract the crypto currency transferring it to the hackers’ account.
Paying the ransom requested by the hackers would waste your money and provide extra incentive for the crooks. Considering extra payload of the ransomware that includes bitcoin stealth, your money is likely to be hijacked before you can use them, even if you intend to pay the ransom demanded by the crooks. That clearly suggests you need to get rid of RSA-4096 encryption virus.
So far, no steps ensure the data scrambled by the infection will be recovered. On the other hand, certain workarounds may and do help. Relevant tips follow.
RSA-4096 generates the following message:

What happened to your files ?
All of your files were protected by a strong encryption with RSA-4096.
More information about the encryption keys using RSA-4096 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)
How did this happen ?
!!! Specially for your PC was generated personal RSA-4096 KEY, both public and private.
!!! ALL YOUR FILES were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
What do I do ?
So, there are two ways you can choose: wait for a miracle and get your price doubled, or start obtaining BTC NOW, and restore your data easy way.
If You have really valuable data, you better not waste your time, because there is no other way to get your files, except make a payment.

Automated cleanup to remove RSA-4096 virus
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed RSA-4096 ransomware, unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of RSA-4096 ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
Restore the encrypted files
RSA-4096 ransomware encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
- ShadowExplorer to accelerate the file-by-file recovery
Evidently, the routine above is quite laborious. Download and install the application called ShadowExplorer. It offers Export feature for much faster retrieval of the latest readable copies.
Backups and removing remaining traces of the RSA-4096 ransomware
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by RSA-4096 ransomware, make sure the removal of RSA-4096 virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
