Google Talk Spam on my Android phone

For the first time, I have received, what I believe to be, SPAM through Google Talk on my Android phone.  I don't use Google Talk, at all, so I'm 100% positive that this is spam.  Upon looking at the notification in the notification bar, I see:

crazieannaxx3@aol.com wants to chat with you.  Will you accept?

This is a vector I haven't seen before, and if anyone has more information, I'd love to hear more.

CAC PIN Scam Alert

This is probably a little late.  As a contractor, we get these notices a little late; my guess is that this came out near the beginning of February.  Of course, the entity that sent our company the alert told us not to click on the link (sound advice) but left the link active in the note.  The SPAM that is circulating has been reproduced below:

Subject: IMMEDIATE ACTION REQUIRED: CAC PIN length increases

Recent world events have uncovered a potential weakness in DoD Common Access

Card (CAC) security systems using a PIN length of less  than 10 digits.

Therefore a new requirement has been established that calls for PIN length

to be at least 10 digits and no more than 14 digits.  Security systems DoD

wide will begin imposing the new restriction on 10-FEB-2011.  In order to

handle the high volume of CAC PIN resets, an automated CAC PIN Reset site

has been stood up.

Please log in to hxxp://www(dot)activeident(dot)com/DoD immediately and

establish your new PIN with the increased length requirement.

NOTE:  If you fail to establish your new PIN before the new restrictions are

imposed, you will need to visit a CAC issuance location before you will be

able to access the network.

I have never heard of CAC PINs being reset over the web, so right away I would be skeptical.  If you receive an email like this, immediately check with your Facility Security Officer and do not click the link.
