A cautionary tale...
A senior prosecution source in Tel Aviv told the BBC that Ruth Haephrati was the expert at implanting the trojan into the unknowing victims office computer system.
He said she would contact a senior executive proposing a bogus business deal.
She would start with a telephone pitch, before offering to send more detailed information on a CD.
She stressed that the offer was so commercially sensitive that only the executive should open it.
Once the CD was installed, the trojan was let loose, but the company and the executive were none the wiser.
The Haephratis were jailed earlier this year.
But the techniques the Haephratis used are being adapted by others. more
