Employees carrying out an insider attack at work can be identified from the language they use in emails, according to psychologists. The Lancaster University study found that an analysis of the email language of employees within an office environment managed to identify 80 to 90 per cent of those actively stealing confidential information and passing it to a provocateur. Their analysis found that the attackers were much more self-focused, using words like "me," "my" and "I" and they used more negative language compared with typical co-workers. They also found that employees conducting an insider attack reduced the extent to which they mimicked the language of their co-workers. This reduction in mimicry, which suggests an inadvertent social distancing by the attackers, increased over time, such that by the end of simulation, it was possible for the researchers to use the combined metrics to identify 92.6% of insiders.
