Re: Adobe's code signing certificate has been stolen


Certificate #

Version
said by Name Game:

Serial Number of the compromised Adobe certificate is 15 e5 ac 0a 48 70 63 71 8e 39 da 52 30 1a 04 88

That would be the code used to sign the flash player install V 11.4.400.252 (Windows 7 64 bits)

Thanks for the info.

Adobe may have signed later versions of Flash with a newer certificate since the one you posted expires on 12/14/2012.

Wouldn't the serial number be different on a renewed certificate ? With the software I'm using every certificate (regardless whether new or renewal) gets a unique serial number from the CA but I don't know if that is universal for all certificate authorities.

Um, it is.

FYI the Adobe Flash Player 11.4.402.278 installers I have are signed with a certificate with the serial number 7e 28 2b 07 49 66 9b 59 5f 79 49 ff 06 13 4e 92.

And I said new (not renewed).

PS: Flash Player 11.4.402.278 was signed with a certificate that expires 10/1/2012. LOL. Clearly they aren't expecting that version to last long!

Also...

It is not public key stuff so the serial number would be the same for everyone who used the product in the time frame the cert was still valid and came with the download...just don't want people to start thinking every user would be getting a unique serial number for their own benefit.

It is a Web Server SSL Certificate

A Web Server SSL Certificate contains the following information:
The certificate holder's name,
The certificate's serial number and expiration date,
Copy of the certificate holder's public key,
The digital signature of the certificate-issuing authority.

Yup.

In short if you download something that is digitally-signed with this certificate consider it suspect.

And that goes for Flash too

so this explains the recent "strange" release of "new" adobe "flash player" installers, where the builds supposedly were identical but, strangely, they were given new build numbers, and without any new releasenotes..

i use adobe flash player 10.x.. build 10.3.183.23 had the compromised digital signature.. build 10.3.183.25 has a new, different digital signature..

Good point! I'd forgotten (or blocked) about that.
