American Express ANZ hit by Zotob
Variants of the Zotob worm caused damage to American Express' internal networks yesterday, but the company said its transactional systems were unaffected.
The Zotob worm, which was discovered last weekend, has been causing havoc in the United States over the past few days. Antivirus firms and Microsoft Australia have been playing down the impact of Zotob in Australia, but ZDNet Australia has discovered that it did wreak havoc.
Sources close to American Express said Wednesday morning delivered a rude shock to many employees -- as soon as they logged in to their network, computers automatically switched off.
"There were a few people who managed to access the network but it was very slow. Internal e-mail alone took between 30 minutes and a few hours to transmit," they said.
