The research analysed cyber-crime across critical infrastructure sectors and found that nearly 100 percent of insider IT sabotage was carried out by people who were 'disgruntled', 'paranoid' and/or 'argumentative'.
It went on to reveal that 86 percent of saboteurs held technical positions, and 90 percent had system administrator or privileged system access.
Some 40 percent of those who sabotaged IT systems were employed at the time of the offence, but the majority of crimes were committed by ex-employees shortly after termination.
Around 64 percent of incidents involved infiltration via virtual private networks using passwords that had not been cancelled, thereby taking advantage of poor security and gaps in their organisation's access controls.
Calum Macleod, European director at security firm Cyber-Ark, highlighted the dangers of companies being frivolous with 'power passwords' and noted how dangerous passwords can be if not properly managed.
