When the file is encrypted people are unable to use them. Bigdata adds the “.bigdata” extension for each file encrypted by it.

As quickly as the encryption is completed, Bigdata places a special text file into every folder containing the encrypted data.The message given by Bigdata text file asking for the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the GlobeImposter family. It actually mentions that the information is encrypted which the only way to bring back it is to use a a distinct decryption key. Sadly, this is absolutely true. The type of cryptography mechanism used by Bigdata is still not correctly examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.
