Anyone know where Palo is on NAT Slipstreaming V2?

L1 Bithead

Hello,

Just curious if there is a definition for the new variant referenced here: https://www.armis.com/resources/iot-security-blog/nat-slipstreaming-v2-0-new-attack-variant-can-expo...

 

Thank you!

Hello,

I could find anything from PAN with searching. I opened a case and will let you know what they tell me.

 

Regards,

Here is the reply from TAC:

 

We released 5 different signatures with Content: 8341 (2020-11-09 UTC).
UTIDs:
59667
59668
59669
59671
59672

Do those cover the v2 variant?

Thanks for looking into that, but 2020-11-09 was before Nat Slipstreaming V2 was disclosed (on Jan 26th 2021).

Good catch. I updated my ticket and will let you know what they come back with.

From support:

 

According to all our evidence, the signatures will work for both variants.

Guess we are already covered. It might be good if someone could test this?

FYI these are set to Alert by default.  I just set ours to Drop.

Hello,

Yes, however if you have your policy set by severity blocking everything medium and higher requires no action:

I always suggest blocking medium and higher. Double checking is a great idea! 

 

Cheers!

Here is how I suggest these settings be setup:
