Wildfire submission log

I don't understand wildfire work.

I have this example that Firewall had wildfire-virus signature but was created wildfire submission log before wildfire-virus identification

why?

Re: Wildfire submission log

Wildfire is for zero day attacks so it looks like there is not an existing verdict for this PE file at the time. Therefore, the firewall has to send the file to Wildfire servers for detonation and analysis. Subsequent logs show that Wildfire determined it to be malware and reseted the connection. Future detection of this same PE file should result in the same action taken, reset-both.

 

Out of curiousity, is it possible to get a MD5 hash of this file?

Hi @allee 

 

I think firewalll already  had wildfire-virus signature when wildfire submission log was generated

unknown sample is uploadd when there is no virus signature. is it right?

as you see detail log The Receive time interval between two logs is 6 seconds.

It's strange to say that the sample was uploaded and installed signature and blocked in six seconds and It is same session.

MD5 is 5cbb230d67b0b0127f369eb3e8288fac

Thanks.

@hbshinright. Looking at the logs again, it looks like there was no actual upload to the WF cloud taking place. Threatvault is saying that there is both a Wildfire and AV signature that has been released since last year. 

 

Looking at the 3rd line of the logs, it looks like it matched against the WF signature.

2nd line then matches the AV signature which triggers the reset-both.

@hbshin,

I would take a look at the WildFire profile assigned to the rule allowing this traffic, it might need some adjustments to actually take action on the WildFire identification.
