A senior member of the management team of a financial institution was experiencing a series of distressing occurrences of unsolicited "admiring", and sometimes worrying, emails and text messages from, what appeared to be, someone within their own organisation. This led to a tense working environment within their division as they began to doubt the motives of those around them. The situation came to a head when they received a very personal email while on holiday, that clearly indicated the sender had personal knowledge of their personal affairs.
LGC were engaged to investigate the circumstances and potential trail of evidence
that may lead to the identification of those involved. Even though the email headers had been forged it was quickly established that the distressing emails were not originating from within the recipient's organisation, but from a rival financial institution. An analysis of staff that had left the client's organisation and were known to be working for the rival indicated a particular person may be involved. That person had the technical knowledge to create the, apparently anonymous, emails and the motive, as the senior manager involved had fired them only 3 months earlier. Further investigations revealed email exchanges between an existing member of staff and the person that had been fired, clearly giving personal information about the manager's personal life.
The case was handed to the Police and the harassment stopped very soon thereafter.
