Either your sample is actually attempting to exploit CVE-2009-4324 and it's evading detecting through our current signature (Exploit.PDF.CVE_2009_4324), our your sample isn't attempting exploit CVE-2009-4324. Either way, your sample would be helpful in order to determine that. Thanks, - Alain On Tue, Jul 28, 2015 at 11:32 AM, P K <pkopen...@gmail.com<mailto:pkopen...@gmail.com>> wrote: Sure. I will submit but as per clamav Database this signature is already in database. Why we should submit sample again?

It’s looking for a two part signature: In your document there are spaces in the string "/S /JavaScript /JS” which are not in the signature. Your document contains the string "media.newPlayer(null)” whereas the signature is looking for “this.” in front of it. Submit your document for possible addition of new or revised signature. -Al- On Tue, Jul 28, 2015 at 03:01 AM, P K wrote: Hi Guys, Still waiting for an answer.
