ThunderCrypt encrypts personal data with hybrid RSA for ransom, demands 0.345 BTC from each victim
ThunderCrypt stuns computer users with its ransom note reading ‘we have encrypted all your personal files’. Sad but true. ThunderCrypt is a malicious decryptor that is going to deprive anyone facing its invasion of access to the overwhelming majority of items stored on a PC. The infection is only selective when it comes to system and program files. Should it scramble the respective data, the system would halt so that the user is unable to read the hacker’s communication. That is the only likely reason why the crooks spare that kind of data.
The introductory explanation also informs the ransomware has applied a customized RSA-2048 cipher to have your data modified. The encryption is really strong enough to withstand any brute-forcing. It is of asymmetric type, meaning the public key is totally different from the private key. The crooks use the public key to encode your data, but the public key is of no use when it comes to eliminating the encryption. Decryption requires a private key. The private key does not arrive at the host machine on any stage of the attack.
Thundercrypt encryptor warning message
The crook’s notice eventually requires the users to purchase a private key. Price announcement by the malefactors indicates 0.345 BTC. The notification also specifies the Bitcoin wallet for transferring the ransom. Time slips along as the victims see the countdown integrated into the ransom note. The crooks allow a couple of days to execute the payment.
On the other hand, they also provide an opportunity to decrypt some files for free. You may select and send up to 3 MB of the scrambled data.
As always, any payments do not satisfy the threat actors. Removal of ThunderCrypt encryption is a challenge. Fortunately, some smart workarounds actually enable a decent degree of ransom-free recovery. You will find relevant details below.
Automated cleanup to remove ThunderCrypt encryptor
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 ThunderCrypt 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 ThunderCrypt 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.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for ThunderCrypt malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
ThunderCrypt 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.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
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.
Backups and removing remaining traces of ThunderCrypt 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 ThunderCrypt encryptor, make sure the removal of this 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.
