Comparison of Entropy Calculation Methods for Ransomware Encrypted File Identification (2022)
Journal Article
Davies, S. R., Macfarlane, R., & Buchanan, W. J. (2022). Comparison of Entropy Calculation Methods for Ransomware Encrypted File Identification. Entropy, 24(10), Article 1503. https://doi.org/10.3390/e24101503

Ransomware is a malicious class of software that utilises encryption to implement an attack on system availability. The target’s data remains encrypted and is held captive by the attacker until a ransom demand is met. A common approach used by many c...
