Nsemad ransomware – a cryptovirus that locks all non-system files and appends .nsemad extension to them
Nsemad ransomware is a file-locking computer virus that encrypts all personal victim data (pics, documents, archives, etc.) on an infected device and then demands a ransom to unlock them. All locked files are appended with a .nsemad extension, thus making them inaccessible.
As soon as any ransomware, including .nsemad file virus, gains entry to a computer, it scans the most frequently used files (.doc, .xls, .pdf, or any other file type) then encrypts all of them. After that, the cryptovirus generates and displays text files, named HOW TO RESTORE YOUR FILES.TXT, with ransom information and demands.
In order to restore access to their files, victims of ransomware virus would have to reach out to the cybercriminals via two given emails – retrnyoufiles23@tutanota.com or John32Dillinger@seznam.cz and, most likely, pay a forward the ransom payment in cryptocurrency Bitcoins.

|---|---|
| type | Ransomware |
| appended file extension | All non-system files receive .nsemad extension |
| Family | Snatch ransomware |
| Ransom note | HOW TO RESTORE YOUR FILES.TXT |
| Distribution | File-sharing platforms, spam emails |
| Criminal contact details | Two emails are provided to establish contact with the cybercriminals – retrnyoufiles23@tutanota.com and John32Dillinger@seznam.cz |
| Malware removal | Remove Nsemad ransomware with anti-malware software to be sure that all its components are deleted properly |
| System fix | Using the FortectIntego app might undo all the damage that the virus might have done to system settings and their files |
The creators of Nsemad ransomware start their ransom note message by stating that all files on the victim's device have been encrypted and that only they have the ability to unlock it. Then they provide two emails which should be used to contact them.
Just like in other ransomware developers, such as Nobu, Igdm, Cerber 4.1.6, and others, Nsemad ransomware makers offer free decryption of three files (not exceeding 1Mb) from the infected machines, thus trying to prove that the necessary tool exists and that they would send it to the victims.
FBI states[1] that paying the ransom only encourages the cybercriminals to expand their attacks and fuels their research for more effective ways to distribute their creations. Furthermore, the ransom money could be used to create more sophisticated ransomware.
With that being said, victims should remove Nsemad ransomware immediately after detection or the first sight of ransom notes. Use professional anti-malware software like MalwarebytesMalwarebytes or SpyHunterCombo Cleaner to perform a full system scan and eliminate the virus with all of its components.
Once Nsemad ransomware removal is completed, we recommend performing a system tune-up. Ransomware usually makes changes to system settings and system files (without encrypting them), and that could lead to abnormal behavior exhibits from your device. Take care of the overall system health with software like the FortectIntego.
The message in the HOW TO RESTORE YOUR FILES.TXT ransom note reads:
