Nmcrypt (.nmcrypt) ransomware forces the users concerned with its attacks to pay amounts far above average for the infections of its type. The malware leverages ultra-strong encryption methods to process files on your PC. This is a general approach that most of the viruses implement. However, an average amount of ransom claimed would not exceed USD 1,000. In the case of nmcrypt ransomware the amount approximates to USD 7,000. This is a substantial amount so that the infection is expected to target corporate victims. Otherwise, the trojan is true to type in terms of the ransom payment method as it claims the sum to be transferred in bitcoins.
In order to get installed on a computer system, the infection is usually made available to the mediators. Those mediators, again, usually agree to share any ransom actually paid with the ransomware originators. IT experts thus classify nmcrypt as a ransomware-as-a-service as it provides a user-friendly GUI to its distributors and is served remotely by the chief crooks.
R Cryptovirus and NMoreira infections are most likely to be the forerunners for the ransomware in question. They look similar both in technical details and in the appearance visible to a naked eye of any victim.
.Nmcrypt virus ransom note
The distributors typically drop the malware via spam campaign. However, nothing prevents them from opting for any other solution. Preventing the invasion is a matter of a comprehensive, continuous security.
The malware landing is followed by its capturing basic details on the machine affected. The data so collected streams to the remote server to be processed by the crooks. Meanwhile, the infection obtains administrative privileges on the host machine. This enables it to kill any processes so that it is normally able to terminate any security applications. It might make a mistake and kill any process so the victims may also suffer from a sudden shutdown of any application and even system might halt itself.
Files encrypted by nmcrypt virus
The nmcrypt ransomware also uses its extended privileges to disrupt recovery options provided by Windows such as Shadow Volume Copies.
The encryption stage follows. Prior to the encryption, the trojan excludes essential system files from the scope of its attack. This ensures the victims will read the ransomware note. The notification is available in every directory that contains the files hit by the ransomware, as well as on the desktop. It notifies the unhappy users of the encryption made by two methods, RSA and AES. Both are strong enough on their own to withstand any plausible attacks by pure computation power. However, their implementation may have certain flaws. To this end, guidance for the removal of nmcrypt ransomware and recovery of the data it corrupts is available below.
Automated cleanup to remove .Nmcrypt 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 .Nmcrypt 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
.Nmcrypt 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 .Nmcrypt 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.
