ePrint Report: Ransomware data recovery techniques

Irimia Alexandru-Vasile

This article presents and explains methodologies that can be employed to recover information from
encrypted files generated by ransomware based on cryptanalytic techniques. By using cryptanalysis
and related knowledge as much as possible, the methodology's goal is to use static and dynamic
analysis as little as possible. We present three case studies that illustrate different approaches that can
be used to recover the encrypted data.
