Abstract

The study explores the impact of the use of the Telegram Mobile application in the context of online gambling, which contributes to addiction and financial problems. The main goal is to find digital evidence on the victim's smartphone using a method from the National Institute of Standards and Technology (NIST), which involves four stages: Collection, Examination, Analysis, and Report. The Tools used include MOBILedit Forensic Express, Magnet AXIOM, and Hash my Files. The process of collecting and analyzing digital evidence is carried out systematically and thoroughly to ensure data integrity. The results included 5 promotional images and gambling winnings posted on the Telegram group, as well as 4 solicitation messages deleted by the offender. Data Integrity analysis was performed by matching MD5Hash and SHA-256 codes using the My Files Hash. The findings provide strong evidence supporting the investigation and enforcement of illegal online gambling activities.
