SyncCrypt / .kk ransomware. How to delete virus and decrypt your files

SyncCrypt ransomware adds kk at the end of the files as a false extension. The original one remains.

The users cannot open files marked with ‘.kk’. Any software cannot read the files because their content has been encrypted. kk is but a hallmark. It indicates the Synccrypt ransomware has hacked the file. The extra extension is not the reason why the file is no longer readable. The troublemaker is the strongest encryption that has processed the content.
The crooks distribute the ransomware with spam. The spam contains a WSF attachment. WSF means Windows Script File. When executed, the file connects to the preset URL.

Name of the WSF file is rather scary. It includes a string ‘CourtOrder’ and a random sequence of digits.
The URL drops a JPG (image) file. This file itself is rather harmless. However, the crooks embed ZIP file to the image. The archive includes three files: sync.exe, readme.png, readme.html. Those files are malicious and actually constitute the Synccrypt ransomware. The infection components are extracted as the JPG file settles down at Temp folder.

Most of the security solutions fail to identify the image file as malware, and only half of the vendors examined detect the sync.exe embedded in the image (the sync.exe installs the ransomware).
An installed instance of the ransomware proceeds with encrypting the data on the computer system with AES cipher. The encrypting key itself undergoes the encryption with RSA script.
Unlike other ransomware specimens, this one does not spare any file formats. Instead, to ensure the system remains functional, the infection omits certain directories when executing its encryption payload. This ensures critical system and program files are exempted from the attack. Thereby, the system and its basic functionality survive. The victims are thus able to find the ransomware’s message dropped on the desktop. The demand will be to pay a certain amount in bitcoins. In exchange, the crooks promise to release the decryptor.
The ransom amount may be quite high. A single Bitcoin amounts to over 4,000 USD as of the end of August 2017. Besides, there are no guarantees that the crooks discharge an effective solution, whether receive the payment or not.
IT security does not have any ultimate solution for data recovery for the victims of SyncCrypt / .kk. Provisional workarounds are available below. They serve best when backups are available, but covers any circumstances.

Automated cleanup to remove SyncCrypt 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 SyncCrypt 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 SyncCrypt 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 SyncCrypt ransomware 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

SyncCrypt 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 SyncCrypt virus

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 SyncCrypt 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.
