BOSTON/NEW YORK, June 6 (Reuters) – Computer security
experts in the United States and Europe warned they have
uncovered evidence that the social networking site LinkedIn
has suffered a data breach that compromised the
passwords of an unknown number of its users.

LinkedIn said via Twitter early on Wednesday that it was
“unable to confirm” that a security breach had occurred. “Our
team continues to investigate,” the Tweet said.

BOSTON, June 5 (Reuters) – Discovery of the Flame virus that
mainly affected computers in the Middle East, has prompted
Microsoft Corp to strengthen the security of a Windows
program that helps customers secure their PCs and update
software.

Mike Reavey, senior director of the Microsoft Security
Response Center, said in a blog post that the world’s biggest
software maker plans to boost security measures on the Windows
Update software that is included with the operating system that
runs the majority of the world’s PCs.

BOSTON, June 4 (Reuters) – Microsoft Corp warned
that a bug in Windows allowed PCs across the Middle East to
become infected with the Flame virus and released a software fix
to fight the espionage tool that surfaced last week.

Security experts said they were both surprised and impressed
by the approach that the attackers had used, which was to
disguise Flame as a legitimate program built by Microsoft.
