　　LONDON - A well-organized group of hackers has engaged in an “industrial
scale” attack designed to cull commercially and economically valuable data from
vital computer networks across Britain， the government warned Thursday.
        　　In one of its most high-profile warnings about sophisticated electronic
attacks， the normally secretive National Infrastructure Security Coordination
Center said hackers believed to be from Asia have targeted parts of the
country's “critical national infrastructure.”
        　　The attacks have been going on for several months and have involved the
communications， energy， finance， health， government and transport sectors， the
NISCC said. Most of the attacks have been against central government computer
systems， though companies and individuals are also at risk， the agency
warned.
        　　“We have never seen anything like this in terms of the industrial scale of
this series of attacks，” NISCC Director Roger Cumming said. “This is not a few
hackers sitting in their bedroom trying to steal bank account details from
individuals.”
        　　Determining the origin of the attacks was extremely difficult， the NISCC
said. The agency said it had traced the attacks back to “the Far East” by
analyzing the numeric Internet addresses stamped within e-mails.Those addresses，
however， can sometimes be faked， and e-mail sent from elsewhere might have been
rerouted through Asian computers.
        　　A spokesman for Britain's Home Office， which oversees the NISCC， said the
agency was talking to authorities in a number of countries to investigate
further， and the government believed it was inappropriate to comment further
while that process was continuing.
