Shurl0ckr is a high-severity risk for your data. It represents a new entry to Gojdue ransomware. Oddly enough, leading IT vendors rate the virus as a low-level threat.
The infection totally deprives the users concerned of access to any meaningful data on their devices. The only way to regain the access, according to the notification dropped by the ransomware, is to pay the ransom. That allegedly releases a decryption key. This key, according to the crooks’ statement, processes the data so that it becomes true to the source.
There is a reasonable doubt whether any payments to do remove shurl0ckr encryption. The fees are quite essential. They affect the victim’s financial welfare and contribute to that of the crooks, or rather to the development and reinforcement of the vicious business.
shurl0ckr ransomware has emerged, according to the reports, at the beginning of February 2018. It propagates with the methods known as a zero-day vulnerability. Those techniques could differ, yet share a critical zero-day specialty as they exploit vulnerabilities once those emerge. That is to say, zero-day refers to a period that limits the response of a malicious attacker to any vulnerability surfaced.

Needless to say, such timeliness contributes best to the success of shurl0ckr propagation. The number of victims is increasing steadily.
Despite the variety of tactics applied by the crooks to drop the malicious encryptor, its post-invasion behavior remains unchanged. Once inside a computer system, the infection creates three folders in Users Profile/Application Data directory. The folder names are as follows:
lock_file; encryption_key; uuid_file.
HOW_TO_DECRYPT_FILES.html is the ransom note the victims are to spot on their devices. This emerges on the Desktop, as well as in any folder that contains affected files.
Remarkably, the trojan creates the ransom note prior to encrypting data. It also tries to drop copies of itself into remote location calling to htpps address that contains ‘onion’ string and other case-specific characters.
.cypher is an extra part of a file name added by shurl0ckr ransomware. The victims would see it at the end of each filename corresponding to items affected. Last but not least, the ransomware displays its ransom note automatically. This urges the users to proceed with clicking the link that basically contains GUI for the shurl0ckr ransom transaction.
The extorters demand the ransom payable in bitcoins. Again, the amount is quite essential, may exceed thousands of USD/EURO etc.
To this end, a comprehensive guide to the removal of shurl0ckr encryption is available below.
Automated cleanup to remove ShurL0ckr virus
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 ShurL0ckr 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
ShurL0ckr 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 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 ShurL0ckr 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.
