According to Australian media reports, the new Sasser internet worm may be
being blamed for 300,000 train travellers being stranded in Sydney
yesterday.
A failure of Sydney's train radio network left many railway
stations closed, with only 20% of trains running.
RailCorp apologised for the inconvenience to customers,
explaining that it could have been the Sasser worm which disrupted
communications between train drives and signal boxes.
"It could very well be a matter related to a virus getting into
the system," said Vince Graham, CEO of RailCorp, "There's no
evidence that hacking is an issue here, the viral infection could
very well have been introduced by our own people not taking
sufficient care."
"It's hard to know whether the Sasser worm was responsible for
the disruption to the Australian railway system this weekend," said
Graham Cluley, senior technology consultant for Sophos. "What is
clear is that all companies should put measures in place to
properly secure their systems from Sasser and other malicious
attacks."
