.thor is to substitute .shit in the family of the notorious Locky ransomware.
The weird dotted strings refer to the file extensions. Both appear as the Locky extortion trojan appends them to the affected files.
The Locky encryption virus has been around for quite a while – a year, at the latest. The plague keeps evolving at increasing pace. To avoid excessive notoriety, the infection modifies extensions added to affected items from version to version. For instance, the .thor surfaced within 24 hours after the release of the .shit.
.thor ransomware note
The .thor ransomware propagates using core infection vector inherent in its generic ransomware. It relies on old-school spamming. The spamming resorts to mass-mailing a rather common business notification. The letter includes an attachment. Basically, the ransomware cannot install, unless the attacked user opens the attached file(s). Among the formats observed so far, ZIP, JS, VBS prevail. Please do not open any attachments without ensuring you trust the sender. You cannot trust one just because you have relevant details in your address book. The hackers compromise emails. That is to say, they get the credentials of the emails which are actually in use. If the stakes are high as in the case of the ransomware, the attacker may analyze your communication with the compromised account. Accordingly, the crook may be able to make it look like a casual message from your partner.
Opening the infecting attachment spawns the ransomware installation. The process runs in the background. Unfortunately, it completes unnoticed by most of the antimalware suites. The installation creates a startup entry so that the trojan can launch automatically. The installed copy scans your PC for most of the file extensions. It spares critical system files only so that the system can run. It wants your operating system to survive. Otherwise, you cannot read its ransom note. The notification would prompt you to open the Locky decryptor page after installing TOR for that purpose. It discloses details of the encryption. A victim learns the ransomware has scrambled the data using AES and RSA ciphers. A grim reality is that the statement is true, as well as those crypto-standards are strong enough to withstand any brute-force attack.
You do not have to pay the ransom of 0.5 BTC as demanded by the Locky at its payment page. A free master decryption key is not yet available. Meanwhile, the smart workaround below shares the best practice of .thor ransomware recovery and removal.
Automated cleanup to remove .thor 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 .thor 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 .thor 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 .thor files 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
.thor 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 .thor 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 .thor ransomware, 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.
