In that case, security companies might release decryptors using the known private key. But for the latest variants, maybe they haven’t been cracked yet.
Now, considering decryption tools, the existence depends on the encryption method. If SoftCobra uses asymmetric encryption, decryption is tough unless the private key is stolen. If it's symmetric, maybe the key is stored locally and can be extracted. But that's less common.
I should also highlight any specific tools or steps, like using Malwarebytes for removal, or trying decryption tools from No More Ransom project if available. Maybe check if SoftCobra is listed there.
I should also mention the role of Security Companies: for instance, if Avast or Bitdefennd are tracking it as a specific name. Maybe SoftCobra is a nickname in certain antivirus databases.
