Morgan Stanley experienced a "very sensitive" break-in to its network by the same China-based hackers who attacked Google Inc's computers more than a year ago, Bloomberg reported, citing leaked emails from an Internet security company.
The emails from the Sacramento, California-based computer security firm HBGary Inc said that Morgan Stanley -- the first financial institution identified in the series of attacks -- considered details of the intrusion a closely guarded secret, the report said.
Bloomberg quoted Phil Wallisch, a senior security engineer at HBGary, as saying that he read an internal Morgan Stanley report detailing the so-called Aurora attacks.
The HBGary emails don't indicate what information may have been stolen from Morgan Stanley's databanks or which of the world's largest merger adviser's multinational operations were targeted, according to the report.
