Inside jobs are often the most dangerous when it comes to the potential network damage to a company, since an angry employee typically has much easier and greater access to network resources than someone on the outside does. Investment company UBS learned this lesson very well recently, when 2,000 servers and 400 offices were knocked down when a disgruntled IT manager, upset over wages, release a logic bomb. Upset over not receiving a bonus as large as he was expecting, former employee Roger Duronio released the attack, which resulted in UBS needing to bring in over 200 IBM employees to fix the situation. Not even their backup systems were functioning properly. Mr. Duronio is now facing some serious charges in court, though his attorney says someone else planted the logic bomb as a “joke”. A joke indeed.
