Cybersecurity consultant points to single attack on Doyen

Drawing on over 20 years’ professional experience in this field, Jake Hockley added: “I’ve never seen an event like this that was done by different people. Considering the odds and coincidences, it doesn’t seem like several separate attacks, it seems to me a single attack. If it was made by one or more people, there is no technical evidence. This is just an attack.”

According to the witness, your company [Marclay Associates] was contracted to investigate the intrusion into Doyen’s computer system “at the end of 2015”, with the forensic information gathering earlier and belonging to another company.

We only have the forensic material that was provided to us, we don’t have access to all the devices and materials that existed at Doyen,” he explained. Jake Hockley, who then described the attempt to enter a computer that belonged to Adam Gomes, a computer technician who worked at Doyen until the beginning of 2015 and who will have left a document containing numerous ‘passwords’ for the investment fund.
