A report has revealed the details of a determined and targeted breach of security at five major oil and gas companies. The cyberattacks, which happened in 2009, completely compromised the firms security systems, with hackers reportedly making off with sensitive technical, financial and personnel data. The attacks, labelled “Night Dragon” by analysts, are part of a rising trend of bespoke, targeted cyber-infiltration techniques, replacing previously random and opportunistic cyberattack systems.
