Episodes
A mysterious hacker group, The 404, initiates a devastating ransomware attack on a Norwegian gas installation. The hack, a co-ordinated phishing and social engineering operation, makes the news. A high profile attack like this quickly gains the attention of AJ, Mark and Maurice aka "Good Shepherd Cybersecurity".
Good Shepherd Cybersecurity is invited to deal with the energy company's ransomware attack. Mark advises the CEO not to pay the ransom, at any cost. It's not clear if he'll take Mark's advice. George, Mark and Violet's estranged father, makes an unexpected appearance. There are clearly serious questions to be answered.
Disastrously, despite all advice, the energy company's CEO is planning to cave in to the ransom demand. Mark buys time, promising his team will extinguish the threat in days. Maurice is as elusive as ever. However, the arrival of a Europol agent on the scene brings some nervous moments for both him and Mark.
AJ informs the team that a fake calendar request to the initial phish victim enabled the hackers to access vital engineering systems. George tries to explain his motives to Violet but she isn't convinced. Mark in the UG and E war room thinks he has worked out the nuts and bolts of the hack. He sends in Lars in Norway to rectify the situation but there is a terrifying reaction.
Mark has enlisted Lars to locate the threat in the plant's underground system of tunnels and comes to a stunning realization about the real nature of the attack. Thanks to a USB key, AJ manages to persuade a skeptical CEO that security training needs to happen. Meanwhile, Fiona sees something that triggers her own doubts about Violet when she runs an errand at Mark's home.
Meet Mark, a man with secrets. This lonely hacker must blag his way into Khromacom's security team and destroy the company. His new colleagues present a heartbreaking dilemma: satisfy his sinister controller or betray his loveable friends?
