A technique is described for protecting file data from malicious programs, in particularly, by decrypting data that has been maliciously encrypted by software such as ransomware. The described technique generates a copy of a first block of a plurality of files stored on a computing device, and also intercepts request(s) from a process executing on the computing device to obtain certain types of random data and system entropy, which are recorded. When the system detects that the plurality of files have been encrypted by a malicious program, the described system determines a cryptographic key determined based on the generated copies of the first blocks of the plurality of files and on the recorded random data, and uses that key to decrypt the plurality of files.
