Introduction
The digital transformation of modern life has increased both opportunities and risks. Alongside the growth of e-commerce, social media, and online communication, new types of criminal activity have emerged: hacking, identity theft, phishing, and online fraud. To address these challenges, Turkish Cyber Crimes Law establishes a legal framework that criminalizes unlawful conduct in cyberspace and sets procedures for investigation and enforcement.
This article provides a comprehensive overview of Turkish Cyber Crimes Law, including its legislative foundations, criminal provisions, enforcement mechanisms, and practical implications for individuals and businesses.
Legal Framework of Turkish Cyber Crimes Law
1. Turkish Penal Code (Law No. 5237)
- The core of cybercrime regulation is embedded in the Turkish Penal Code (TPC), especially Articles 243–246.
- These provisions cover:
- Article 243: Unauthorized access to computer systems (hacking).
- Article 244: Disruption, destruction, deletion, or alteration of data.
- Article 245: Online fraud (e.g., phishing, credit card fraud).
- Article 246: Unauthorized use of payment instruments.
2. Law No. 5651 on the Regulation of Internet Publications (2007)
- Focuses on internet content regulation and liability of service providers.
- Provides mechanisms for content removal, access blocking, and monitoring unlawful online activities.
- Targets online dissemination of crimes such as child pornography, terrorism propaganda, and illegal gambling.
3. Law No. 6698 on the Protection of Personal Data (KVKK)
- While not a criminal law, KVKK complements cybercrime prevention by regulating data protection.
- Unauthorized collection, processing, or sharing of personal data can lead to both administrative and criminal sanctions.
4. International Conventions
- Türkiye is a party to the Budapest Convention on Cybercrime (2001), aligning its domestic law with international standards.
