Google said the attacks were very targeted and resulted in the theft of intellectual property.  Adobe confirmed its network was also breached in the same attacks but did not provide any details on what was stolen.

In a statement, Juniper Network said it was investigating “a cyber security incident involving a sophisticated and targeted attack against a number of companies.”

According to public chatter, the attackers originated in Taiwan and included a hijacked Internet addressed owned by Rackspace. The hosting firm has confirmed that its systems “played a very small part” in the attacks.

Details on the cyber-attacks are beginning to trickle out.   According to Dan Kaminsky, a security researcher who was briefed on the IE vulnerability used in one of the attacks, the exploit was targeted at a Windows XP machine running Internet Explorer 6.
