On 7 June 2004, a cyber-attack was launched against Cell C's computer network, disconnecting approximately 80% of it. The appellant, who had been employed by Cell C as an IT Remote Access System Administrator until three weeks prior, was charged with contraventions of section 86 of the Electronic Communications and Transactions Act 25 of 2002 (ECT Act). The trial commenced on 29 October 2005 in the Specialised Commercial Crimes Court, Johannesburg. On 14 January 2015, the appellant was convicted on count 1 (unlawfully accessing Cell C's computer network without authority under s 86(1)) and count 3 (unlawfully modifying, altering or destroying data causing partial network failure under s 86(5)), but acquitted on a third charge. On 17 August 2015, he was sentenced to a fine or 12 months' imprisonment on count 1 and three years' imprisonment on count 3. The Gauteng High Court dismissed his appeal on 9 March 2017. The high court granted leave to appeal to the SCA on 5 June 2018. Evidence showed that a dial-up connection from the appellant's home computer using credentials of a Cell C employee (T Walter) was made at the time of the attack. The appellant claimed his wife accidentally accessed the system, but did not call her as a witness. The trial took 11 years from first appearance to sentencing.
