Hi. I’m seeking for some opinions. I am attached to a local banking company in Malaysia. Recently one of my ex-staff in the Customer Relation department has left the company with less than 24 hrs notice resignation. Other staffs were perplexed and also kept thinking about why. Someone has taken his own initiative to check his computer station (I’m not quite sure that guy was doing) but he suspects there could have been some data from has been stolen. All panicked. How can we investigate that possibility? What information we should look into? Is there any quick way to prove something of data theft possibility? The nightmare is, worst case scenario, he has copied some of confidential data of high customer profiles and could have sold it. Should we invite computer forensic team from local enforcement agencies or we do it the 'forensic' thing?
