Early speculation focused on the Abobe Reader zero-day exploit as the source of the Chinese attacks on Google and other corporations earlier this week, but Adobe may be off the hook--or at least share the blame. Microsoft has determined that an unknown flaw in Internet Explorer was one of the holes used to launch the attacks which have led to Google threatening to shut down its Chinese operations.
The truth outs.
Early reports (notably WashPo) didn't mention Windows, Office, Microsoft or any Microsoft product, but instead hypothesized Adobe, or some other un-named software was at fault.
After all what platform is involved 99.99% of the time, even if the bug was in Acrobat... it usually takes a Windows base to actually activate the malware?
