iSec has published a brief report [pdf] into the widely-reported "Aurora" attacks on Google (and others) that allegedly orginated from the Chinese Government. The report provides an interesting insight into a recent sophisticated attack that I suspect few organizations would have been able to repel, and is well worth reading.

An important point from the end of the report is that the:
"...most interesting aspect of this incident is that a number of small to medium sized companies now join the ranks of major defense contractors, utilities and major software vendors as potential victims of extremely advanced attackers. This is concerning for many reasons, not the least of which is that even most Fortune-500 companies will not be able to assemble security teams with the diversity of skills necessary to respond to this type of incident."
