This documentary examines the growing problem of identity theft and how organised crime has moved online as internet banking and shopping increase. Using data hacks, spam email and malware, criminal gangs are now able to steal account details, then freely trade them on the so-called dark web. They will telephone their victims, convincing them to transfer money into an account they control, or will extract personal information which allows them to take over bank or credit card accounts. The programme highlights the case of one man who has tricked the banks, traumatised his victims and stolen tens of thousands of pounds in a single day.
