Getting Evidence from Online Platforms, Services, Banks and Providers

Questions
Who is the handbook for?
Police and sheriff's office investigators, prosecutors' staff, fraud and financial-crime analysts, private and corporate investigators, and journalists who cover cybercrime. Anyone can sign up.
Is it free?
Yes. You sign up with your name, work email, organisation and country, choose the edition or editions you want, and we email you a personal download link for each.
Is this legal advice, or an official publication?
No. Ministry of Cyber Affairs is an independent news, guides and directory service on cybercrime and cybersecurity. It is not a government body, police force, court, bank, provider or recovery service. The handbook describes processes as official sources describe them; your prosecutor, legal adviser or court decides what applies to your case.
How were the contacts and facts checked?
Each portal, address and legal reference was read on its official page on 18 October 2026, and every claim was rechecked by an independent reviewer against its source. Each chapter ends with its sources. Companies change contacts without notice, so confirm on the official page before you serve process.
