Global Threat Condition

January 25, 2010: As Microsoft has released their "out-of-band" patch for the Internet Explorer vulnerability that was used in Operation Aurora (MS10-002) as well as a low amount of observed usage in the wild, we have lowered the threat condition to Severe. Users are still advised to confirm coverage for the vulnerability and all associated malware as well as deploy all relevant patches within a timeframe that complies with their risk management policy.

Elevated

An unpatched or recently patched vulnerability is present on many systems worldwide but requires user interaction to be exploited.

There is new malware activity, but it is not widespread.

Low

There is no direct threat to systems that have been patched.

No new significant malware activity has been reported.
