Remove Nsemad ransomware And Recover Encrypted Files

Easy Steps To Delete Nsemad ransomware

Nsemad ransomware is a deadly crypto-virus that belongs to the family of Snatch ransomware. As soon as this hazardous parasite gets into the Windows computers, it encrypts files and then asks victims to pay the attackers a sum of ransom for the decryption. It uses a very strong cryptography to lock images, videos, audios, PDFs, documents, spreadsheets etc. and makes them completely inaccessible. The infected files can be easily identified as it renames them by appending “.nsemad” extension with each of them as suffix. Due to this weird extension, all the compromised data can be easily identified.

Depth Analysis of Nsemad ransomware:

After completing the data encryption, Nsemad ransomware drops a ransom note titled “HOW TO RESTORE YOUR FILES.TXT” on each affected folder and informs victims regarding the attack. It also asks them to contact the attackers via the provided email address to get further details. The subject of the mail must be the extension appended to the locked files or the name of victims’ companies. The message alerts users that public email service providers (e.g. Gmail) can block the attackers’ letters and hence, they should use Tutanota or protonMail to avoid this.

Victims can also test the decryption by sending three encrypted files to Nsemad ransomware authors. The total size of the test files should be less than 1 MB (non-archived) and should not contain valuable information like backups, databases, large Excel spreadsheets etc.). Crooks will decrypt those files and send them back to prove that the decryption is possible. Victims are also warned not to rename the infected files or turn off/restart NAS (Network-attached storage) equipment, otherwise it may lead to permanent data loss.

Should You Pay The Ransom?

Whatever the circumstance might be, you should never consider dealing with Nsemad ransomware authors as they will not decrypt your files even after taking the extortion. Keep in mind that the only objective of such criminals is to extort illicit profits from the victimized users. You have absolutely no guarantee that they will provide you the required software even if the ransom is paid. It has been tendency of such criminals that they often disappear soon after the payment or deliver rogue software to the victims in the name of decryption tool which only harms the device severely when installed.

What Should The Victims Do?

For any victimized person, the first thing they need to do here is to perform Nsemad ransomware removal from the computer as early as possible. After that, they can try to restore the compromised data via alternative methods such as Shadow Volume Copies or backups. If these options are not available, they you can try a powerful data-recovery application.
