Unveiling the Cryptographic Maze: A Comprehensive Exploration of Crypto-Ransom ware Lifecycle and Mitigation Strategies

Abstract

Decoding the Menace: Unraveling the Crypto-Ransomware Encryption Techniques and introducing the Pre-Encryption Detection Algorithm (PEDA). This paper delves into the pervasive threat of ransomware, a malicious software that obstructs user access to systems and files, coercing victims into paying a ransom. Specifically, the focus is on crypto-ransomware, which employs advanced encryption methods to lock diverse file types, demanding payment for decryption keys. The evolution of ransomware encryption techniques underscores the need for robust detection systems. In response, this study introduces the Pre-Encryption Detection Algorithm (PEDA), designed to identify crypto- ransomware at the pre-encryption stage, before any files are locked. The algorithm's initial phase involves signature comparisons, paving the way for an enhanced defense against the growing threat landscape.
