Despite being accused of altering evidence, forensics specialist Keith Jones stood firmly by his earlier testimony that whoever brought down the UBS PaineWebber network had to do so from inside Roger Duronio's home. Duronio is the systems admin on trial for the attack.
The prosecution's forensics expert and star witness sparred with the defense Wednesday, taking on often heated questions about hackers and the validity of his analysis.
A forensics investigator testifying at the computer sabotage trial of a former systems administrator for UBS PaineWebber detailed how each line of code in the trigger helped set off a devastating logic bomb.
Planning for success, the perpetrator of the UBS attack installed the trigger mechanism of the logic bomb that brought down the company's network four years ago, twice on every server it targeted.
In the ongoing UBS computer sabotage trial, the government's forensics expert testified that he connected defendant Roger Duronio's username and home computer directly to the logic bomb that took down the company network.
As the trial continues for an ex-UBS systems administrator charged with sabotaging the company's networks, the defense attorney called into question the investigator's evidence and means of collecting it, as well as information and people who weren't investigated.
A U.S. Secret Service agent came under intense cross-examination in a computer sabotage trial Tuesday. Days after testifying that agents found a printout of malicious code in the defendant's bedroom, the defense spent most of the day hammering the lead investigator.
The defense in an ongoing computer sabotage trial is suggesting that a hacker used IP spoofing to impersonate his client and plant the malicious code that took down part of the UBS PaineWebber network four years ago. Security pros say that's nearly impossible to do.
This past week, the government laid out its case for how the defendant allegedly planned to profit from taking down UBS PaineWebber's network. Prosecutors say his "risky" investments would have only paid off if the stock dropped. The defense argues he simply had an aggressive investment strategy.
A U.S. Secret Service agent testified that a search of Roger Duronio's home turned up part of a logic bomb on two of his home computers and in a printout found lying on top of a bedroom dresser. The defense, meanwhile, pounded away at UBS PaineWebber's security lapses.
A financial advisor testified that the defendant bet heavily on "put" contracts that would pay off if the company's stock crashed quickly. Soon afterwards, prosecutors say, the defendant's logic bomb took down much of the company network.
Prosecutors say the accused caused chaos by planting simple code. The defense says dozens of people had the access to cause the problem without being identified
Defendant Roger Duronio was "visibly upset" and red-faced and delivered an ultimatum: Give him a lucrative contract or he'd walk, said Duronio's ex-boss, testifying against him in a criminal hacking trial.
The logic bomb had a "catastrophic impact," bringing operations to a standstill and wiping out servers around the country, according to testimony from an IT manager for the company.
Prosecutors claim the defendant, a former systems administrator for the company, set off a logic bomb designed to crash the network to get revenge for not being paid what he thought he was worth. But the defense argues anyone could have made the "sophomoric" attack.
The trial is scheduled to start Tuesday for a former employee charged with building and planting malicious code that took down two-thirds of the company's network, hindering investment trading for several weeks and racking up $3 million in recovery costs. But the defendant's lawyer says the cops got the wrong man.
