A common misconception in security is that if you use non-Microsoft products, you’re safe from malware attacks and exploits. Once again, this has been disproved by a zero day attack on a non-Microsoft application–specifically a local word processing application in Japan.

Recently we’ve received a sample of a malicious document that contains an embedded file that can be executed by exploiting a flaw in this Japanese application’s document viewer. Initial analysis shows that the embedded file is actually a Trojan that gathers information from the affected system.
As of now, other activities of this Trojan are still being verified and a corresponding solution is already in the works. Stay tuned for updates…
