Wireshark · Wireshark-dev: Re: [Wireshark-dev] [Full-disclosure] SniffJoke 0.3 release and requestfor feedback (forw)

["Tamazov, Artem" <artem.tamazov@xxxxxxxxxxx>]

Hello Sebastien,

 

If you consider there is a bug in wireshark, please create relevant bug in BugZilla.

Please see [http://wiki.wireshark.org/ReportingBugs] for instructions.

I believe every WS developer will appreciate that.

 

thanks,

artem//

   SniffJoke has a nice/interesting characteristic : It is *only* used by the sender *not* by the receiver. 

   SniffJoke, thanks to some tricks - which *does not* have impact on the receiver's TCP/IP stack (for all OSes?) -, is able fool sniffers and some others network tools.

   I would expect wireshark seeing the traffic as the OS is able to see it ... IOW, if receiver's OS is able to re-assemble correctly the traffic, wireshark should be able to do so too. Therefore, I would consider this as a bug in wireshark since OSes (all?) would be able to reassemble the traffic without any problem. (Although the next question would be : who will spend time to analyze SniffJoke tricks and fixes the TCP dissector?)

   Also, I'm not convinced people will think that wireshark would consider it as a cracking tool since the receiver's OS is considering this SniffJoke's traffic as valid ...

Regards,

Sebastien

As the purpose of Wireshark is to display network traffic to analyse
problems, I see no use in competing in a race to cloak and uncloak traffic
with Sniffjoke. That would put Wireshark in the list of cracking tools which
might have a negative effect on the places where it is allowed to be used.
So I would not consider this a bug and I would *not* consider being able to
reassemble Sniffloke traffic a feature to implement.

Just my $0.02
