Most security experts will advise against paying the ransom
demands of the malware writers because doing so only helps to finance their criminal enterprise and keep them in business. One of the reasons that folks get infected is because someone before them paid the bad guys to decrypt their data. The more people that pay the ransom, the more cyber-criminals are encouraged to keep creating ransomware for financial gain. Further, there is never a guarantee
that paying the ransom will actually result in the restoration (decryption) of your files.
Some ransomware victims have reported they paid the ransom and were successful in decrypting their data. Other victims have reported paying the ransom only to discover the criminals wanted more money
...demanding additional payments with threats the data would be destroyed or exposed. Still others have reported they paid but the cyber-criminals did not provide a decryptor or a key
to decrypt the files, while others reported the decryption software
they received did not work
, resulted in errors and in some cases caused damage to the files. Most cyber-criminals provide instructions in the ransom note that allow their victims to submit one or two limited size files for free decryption as proof they can decrypt the files. However, decryption in bulk may not always work
properly or work at all and decryption of very large files may be unsuccessful even with the criminal's decyption tool. In some cases victims may actually be dealing with scam ransomware
where the malware writers have no intention or capability of decrypting files after the ransom is paid
Keep all this in mind if you are considering paying the ransom since there is never a guarantee decryption will be successful
or that the decrypter provided by the cyber-criminals will work as they claim.
