INNOVATIVE METHODS OF IDENTIFICATION AND DOCUMENTATION OF ORGANIZED CYBERCRIMINAL GROUPS’ ACTIVITIES

Abstract

Innovative methods of identification and documentation of organized cybercriminal groups’ activities. The article examines a comprehensive set of innovative methods for identifying members of organized cybercriminal groups and documenting their unlawful activities in the context of criminal proceedings. It is established that effective identification under modern conditions is based on the principle of multi-source digital data correlation, since no single technical indicator is sufficient to prove a person’s involvement in a criminal offense. The method of deep network artifact correlation is analyzed, comprising complex examination of technical parameters of network connections – TTL (Time To Live) values, TCP Window Size, TCP option sets, and inter-packet timing – which form the “network fingerprint” of a device even when VPN (Virtual Private Network) or TOR (The Onion Router) infrastructure is used. The article also addresses TLS/SSL (Transport Layer Security / Secure Sockets Layer) fingerprinting via JA3/JA4 algorithms, blockchain clustering using multi-input heuristics, OSINT (Open Source Intelligence) correlation of pseudonyms, linguistic attribution (stylometric profiling), malicious code similarity detection, behavioral biometrics, and digital device fingerprinting. Special attention is given to forensic documentation procedures for electronic evidence: the use of write-blocker devices, bit-by-bit imaging, computation of cryptographic hash values (MD5, SHA-256), and maintaining the chain of custody. It is argued that the integrated application of these methods creates a multi-layered attribution model combining technical, financial, and behavioral markers that satisfies the requirements of admissibility and reliability of electronic evidence in criminal proceedings. The conclusion is drawn regarding the necessity of systematic implementation of integrated analytical platforms, enhanced training of investigators in digital forensics, and strengthened international legal cooperation in combating cybercrime.
