EDIT 2015-11-05 23:19+01:00:
the title now:
Mozilla Cloud non-Decryptable Download?

This topic contains the intrusive disruption of my topic by another Gentoo member, for which I am unable to continue, if this post, currently last, is not removed:

< this same topic >
https://forums.gentoo.org/viewtopic-t-1031758.html#7837184

I hope this won't continue to be happening in other topics of mine.

I had wanted to try to contain the intrusive intentional ruining of my topic here:

Uninstalling dbus and *kits (to Unfacilitate Remote Seats)
https://forums.gentoo.org/viewtopic-t-992146-start-75.html#7837090

the reasons why there, and not here, is explained there clearly.

But to no avail. Yes I have reported the post. We'll see. (If the link to the intrusive post becomes dead, it has been removed.)
EDIT END
==== underneath here content unmodified, remains as of the first timestamp =====
Not sure at all what this will come out.
Code:

I make make un unrelated post (planned previously) out of this.

However, if this is something interesting (just take a look at how interesting this topic of mine

SSL Decode & My Hard-Earned Advice for SPDY/HTTP2 in Firefox
https://forums.gentoo.org/viewtopic-t-1029408.html

appears to be; currently3498 views), it is important that the files don't be easily dismissed as unauthentic.

Patience, I kindly ask of readers.

miro ... yes, and if you include a URL in every post you make (as you do) then crawlers will harvest those links, and so the views increase ... isn't technology amazing. Your posts, this one especially, are esencially nonsensical, and you seem to be under the impression that people are reading.

best ... khay

I'll now post what I had prepared previously.

Still not sure where this issue goes.
Code:

993e1cf1d0305fa519c9941189221c01b974d3596de21615768e20a7e521eac4  dump_151029_1757_g0n.pcap
73a1f52a202450bab08632362bb74d38f4b1cbd8b45f92cbaf2314eb225d406f  Screen_151029_1757_g0n.mkv

No, I won't make un unrelated post out of this. What other topic I planned previously will go separately elsewhere.

These files are:
Code:

-rw-r--r-- 1  86340324 2015-10-29 18:32 dump_151029_1757_g0n.pcap
-rw-r--r-- 1 176027816 2015-10-29 18:32 Screen_151029_1757_g0n.mkv

or:
Code:

-rw-r--r-- 1  83M 2015-10-29 18:32 dump_151029_1757_g0n.pcap
-rw-r--r-- 1 168M 2015-10-29 18:32 Screen_151029_1757_g0n.mkv

and the priority is just the network capture. Screencast hopefully later, and maybe even in some other fashion (vimeo.com). No room on croatiafidelis.hr .

This topic follows on the heels of this other topic:

================================================================================


The issue with this capture is not too hard to see for a trained eye. A huge portion of the entire capture of 83M, which is a huge traffic for simply browsing which I did for those 33 minutes, without downloading any video or another file of that order of magnitude, a huge portion is here:

grep cloudfro dump_151029_1757_g0n.conv-ip-with-names
<and the legend (the first two lines) is of my addition>
Code:

                                                                                                                                     |       <-      | |       ->      | |     Total     |    Relative    |   Duration   |
                                                                                                                                     | Frames  Bytes | | Frames  Bytes | | Frames  Bytes |      Start     |              |
192.168.1.3                                       <-> 54.192.55.37(d3581xjroqhv5u.cloudfront.net)                                     47095  70986165   25543   1799129   72638  72785294    59.282923000       249.2311
192.168.1.3                                       <-> 54.192.12.211(d15a7gkmxinlzq.cloudfront.net)                                       50     41019      48      4338      98     45357    58.493768000       116.7505
216.137.59.141(dnn506yrbagrg.cloudfront.net)      <-> 192.168.1.3                                                                        45      4512      41     26783      86     31295    59.223058000       116.0383

and it is especially obvious that the one conversation of all, with the 54.192.55.37(d3581xjroqhv5u.cloudfront.net), downloaded into my system a little short of 70M (the 47095 Frames or 70986165 Bytes, under "<-" ), and so it has made for the great great majority of the traffic.

Maybe that is the regular way Firefox updates. It really may be.

But if it is the regular way Fox updates, then it ought to be in the open, for me, a user of Mozilla Firefox, a program that is Free Open Source Software, at least as it is claimed to be such but its developers (and I still hope they do keep to some standards, at least a significant part of its community).

I'll try and see if I can manage to get the TCP or SSL streams in the open, and see what exactly Mozilla downloaded into my system, and then I can, hopefully, find it in my system, and get an inkling at least, what it does, or is, there for.

Next.

Then it ought to be in the open. For me. Encrypted with PFS (Perfect Forward Secrecy), so no one can snoop on it, but if I cared to store and keep the "CLIENT_RANDOM" keys in my $SSLKEYLOGFILE (or in some other fashion), then it must be open for me to see what Mozilla from its cloud downloaded into my system, if that was the case, as it looks to me.

The filter is: "ip.addr==54.192.55.37" (without quotes).

Or maybe better: "(ip.addr==54.192.55.37) || (ip.addr==54.192.12.211) || (ip.addr==216.137.59.141)" (without quotes), but pls. note that I'm guessing only...

I'll take this latest.

I entered (pasted) that string in the Wireshark filter, hit Enter to get that filtered display active, and then File > "Export Specified Packets". "Packet Range" is "All Packets", the "Displayed" is selected already, and I saved it as:

dump_151029_1757_g0n_MozCloud.pcap

If you, by doing the same, get:
Code:

-rw-r--r-- 1 miro miro  75195628 2015-10-30 16:45 dump_151029_1757_g0n_MozCloud.pcap

which is in human readable (the '-h' switch)
Code:

-rw-r--r-- 1 miro miro  72M 2015-10-30 16:45 dump_151029_1757_g0n_MozCloud.pcap

then probably my suggestions can be followed (and if you're into network capture, maybe you can tell all of us more; there will be encryption that I'm afraid I can not decrypt, later; perfectly possible only because my knowledge is insufficient, but also that not all tools are there for decryption, even if I were expert)...

I now open that dump with those just exported specified packets selection in Wireshark.

Now at least we are dealing with only 7 tcp streams, while in the complete dump, there were 472 tcp streams

( you get streams out if you put [0-7] for $the_number in "tcp.stream eq $he_number" in the filter for that MozClould.pcap dump (and you get nothing if you put 8 or greater; and in the complete dump, you get a different tcp stream if you put [0-472] in "tcp.stream eq $the_number", such as "tcp.stream eq 3" or "tcp.stream eq 405", respectively )

.

But can these streams be decrypted? And if, how?

I'll try and cut to the chase. Because I'm beginning to be in a hurry. I need Fox as I have to use internet banking for my monthly paying of my bills, and I have only in Fox some trust lingering, from among the javascipt enabled browsers that I could do those payments with.

But my not being able to decrypt the huge payload (we are just about coming to it next), is making me worry, and either I go and pay my bills at the counter instead of via the internet banking, or...

We still have dump_151029_1757_g0n_MozCloud.pcap open in Wireshark.

Enter the filter "tcp.stream eq 5" (without quotes).

Right click on any frame with TLS1.2, follow SSL stream, and save as:

dump_151029_1757_g0n_MozCloud_s5-ssl.dump

You should get:
Code:

$ ls -l  dump_151029_1757_g0n_MozCloud_s5-ssl.dump
-rw-r--r-- 1 miro miro 136352 2015-10-30 22:30 dump_151029_1757_g0n_MozCloud_s5-ssl.dump
$ ls -lh  dump_151029_1757_g0n_MozCloud_s5-ssl.dump
-rw-r--r-- 1 miro miro 134K 2015-10-30 22:30 dump_151029_1757_g0n_MozCloud_s5-ssl.dump

Can't delve into it, in a hurry for reason stated above, but it's some tiny adobe managed video, in some likelihood, but it's partial content, I think I saw somewhere when following it (just open it with:
Code:

$ hexedit dump_151029_1757_g0n_MozCloud_s5-ssl.dump

)

But it's this next stream... Do the same right click as before, but choose "Follow tcp stream" instead. And be patient. It's there, we have arrived at where the story might start to become interesting.

Be patient (unless you have a really powerful computor). Do save it as:

dump_151029_1757_g0n_MozCloud_s5.dump

but all those megabytes need a little time to reassemble from those some 40000 different frames (packets).

You should have this eventually:

Code:

$ ls -l  dump_151029_1757_g0n_MozCloud_s5.dump
-rw-r--r-- 1 miro miro 67764933 2015-10-30 22:41 dump_151029_1757_g0n_MozCloud_s5.dump
$ ls -lh  dump_151029_1757_g0n_MozCloud_s5.dump
-rw-r--r-- 1 miro miro 65M 2015-10-30 22:41 dump_151029_1757_g0n_MozCloud_s5.dump
$


And here my insufficient knowledge, or encryped content (coming at it in a moment), makes me unable to view what those 65M contain.

Get ready to follow by studying "man hexedit" (emerge hexedit it you haven't yet).

Code:

$ hexedit dump_151029_1757_g0n_MozCloud_s5.dump

Next, search for, in hex, string "474554" (without quotes), which is the string that GET'd content starts with, and take notice how many you find. They should be three (3) only.

Stay with the third 474554 that you found. Mark it. go to end. Copy.

You'll get a jocular warning ( my install is:
Code:
 # equery l hexedit
 * Searching for hexedit ...
[IP-] [  ] app-editors/hexedit-1.2.13:0
#

):
Code:

       Hey, don't you think that's too big?!
             Really copy (Yes/No)
Enjoy the joke, answer "y" and paste it into a file:

dump_151029_1757_g0n_MozCloud_s5_03.dump

Move again to the start of the third GET and truncate at that point.

Go to beginning, and from there get one, and another time to the start of GET. So you are at the second GET.

Just like before, mark, move to end, copy and paste into a file:

dump_151029_1757_g0n_MozCloud_s5_02.dump

To beginning, and move to the second GET, and truncate there.

Go to beginning, and from there go to the start of the last GET. Mark, move to end, copy and paste into a file:

dump_151029_1757_g0n_MozCloud_s5_01.dump

You should now have:
Code:
$ ls -l dump_151029_1757_g0n_MozCloud_s5_0?.dump
-rw-r--r-- 1 miro miro  1484476 2015-10-30 23:36 dump_151029_1757_g0n_MozCloud_s5_01.dump
-rw-r--r-- 1 miro miro 13834287 2015-10-30 23:36 dump_151029_1757_g0n_MozCloud_s5_02.dump
-rw-r--r-- 1 miro miro 37479495 2015-10-30 23:35 dump_151029_1757_g0n_MozCloud_s5_03.dump
$ ls -lh dump_151029_1757_g0n_MozCloud_s5_0?.dump
-rw-r--r-- 1 miro miro 1.5M 2015-10-30 23:36 dump_151029_1757_g0n_MozCloud_s5_01.dump
-rw-r--r-- 1 miro miro  14M 2015-10-30 23:36 dump_151029_1757_g0n_MozCloud_s5_02.dump
-rw-r--r-- 1 miro miro  36M 2015-10-30 23:35 dump_151029_1757_g0n_MozCloud_s5_03.dump
$


Now, let's go get the gzip data, if we can:
Code:

$ hexedit dump_151029_1757_g0n_MozCloud_s5_03.dump


Search, in hex, for "1F8B08" (without quotes). Only one found. Mark. Move to end. Copy. Paste into file:

dump_151029_1757_g0n_MozCloud_s5_03.gz

And here we go, where I have no idea how to get what that data is:

Code:

$ file dump_151029_1757_g0n_MozCloud_s5_03.gz
dump_151029_1757_g0n_MozCloud_s5_03.gz: gzip compressed data, ASCII, extra field, encrypted
$

Do you see these unusual info the file command is telling us?

And sure, if I try:
Code:

$ gunzip dump_151029_1757_g0n_MozCloud_s5_03.gz
gzip: dump_151029_1757_g0n_MozCloud_s5_03.gz is encrypted -- not supported
$


And it's similar, if I process 02.dump like that, with:
Code:

$ file dump_151029_1757_g0n_MozCloud_s5_02.gz
dump_151029_1757_g0n_MozCloud_s5_02.gz: gzip compressed data, has CRC, extra field, has comment, encrypted, last modified: Sun Oct 19 05:36:28 2003
$ gunzip dump_151029_1757_g0n_MozCloud_s5_02.gz
gzip: dump_151029_1757_g0n_MozCloud_s5_02.gz is encrypted -- not supported
$


I'm not saying this isn't legitimate, as I don't know that it isn't.

Nor that it is legitimate.

I'm not so very bright, but neither stupid. I think I'll try and ask about this Mozilla devs, on their mailing list or some such place, or on Wireshark mailing list.

And in the meantime, I can't use Fox for internet banking, and the money that I need to pay, as every month, is due for payment...

Either I go to the bank or post office and pay over the counter (but what then do I have computers for?), or...

Regards!

title will be:

Mozilla Cloud non-Decryptable Download?
================
(will change it later)
---

I owe you this one, readers, if there are any (maybe you better not read, or some will get upset if you do...)

I owe you this one, gentle readers:
I wrote:

Or...? Or what? lingers the question.

Well, what for did I figured out, for myself and for other people, how to install gentoo air-gapped:

Air-Gapped Gentoo Install, Tentative
https://forums.gentoo.org/viewtopic-t-987268.html

?

And why do I try to spread some good methods of backup (would have been better if I had time to make a separate tip for it, true):

Postfix smtp/TLS, Bkp/Cloning Mthd, Censorship/Intrusion
https://forums.gentoo.org/viewtopic-t-999436.html#7613044

?

Surely I wiped the hard disk clean with the Air-Gapped complete system backup, with the Air-Gapped that could not have any intrusions on it... By cloning the air-gapped master system onto this one... But all these methods are explained in the respective links just given.

And if this matter shows to be nothing to worry about, well, then it need to be possible to get the content of those downloads in the open. Without becoming a rocket scientist to be able to do it...

If Zilla is really FOSS (...hope lingering).

No one is allowed to encrypt things in my computer, behind my back, not even Mozilla (if that was really its cloud downloading in my machine).

And neither should behind your back, gentle readers.

And surely, I'm back to using Dillo. Such a fine worry-free experience. I dream good FOSS people will help the Dillo devs to make Dillo much much better, more complete, and competing with the commercial big browsers...

Back to the issue. Anyone knows how to decrypt those?

Can you help us (It is likely that other users will have issues like this)?

Because it might take me longish to figure this out....

(If I do, I'll tell all of you!)

Regards!

Ah, and I forgot.

The entire snapshot of the system, with that download in it, is saved, and will be available for weeks, maybe even months from now.

With the backup/cloning method that I linked to in the previous post.

So no information, if there some real expert happens to want to look into this, has been lost.

Good night!

I can not believe I had forgotten to post the SSLKEYLOGFILE-151029.log....

It is there now.

No, that wouldn't decrypt the Moz Cloud download, no. But that decrypts everything else.

Anyway, I updated the:

http://www.croatiafidelis.hr/foss/cap/cap-151029-MozCloud/

and you can get the files by downloading just the dLo.sh, and 'chmod 755' to it, then into an empty new dir where you have privs, and ./dLo.sh to get all the files. I am now also uploading the Screen_151029_1757_g0n.mkv, but I'm afraid I won't have that much room left on my NGO's website...

And I mailed to Mozilla dev-security mailing list:

Mozilla Cloud non-Decryptable Download?
Code:

https://groups.google.com/forum/#!topic/mozilla.dev.security/abSHPU4EaP8

the link above is for pasting into your browser's address bar, because, like this:

https://groups.google.com/forum/#!topic/mozilla.dev.security/abSHPU4EaP8

the '/#!' seems to erroneously end the reading of the address for phpBB...

EDIT 2015-11-01 20:42+01:00:
Ah, managed to get the address, it's the Schmoog's way, nobody else's:

https://groups.google.com/d/msg/mozilla.dev.security/abSHPU4EaP8/s-5UMFJsCAAJ

(such as, it don't let me view it with Dillo, the shingilibindildiyots!)
EDIT END

(
Anyway, only the Schmoog, really, could come up with such a standard for http addresses. The Schmoog rapist of the standards, like with the SPDY and the HTTP2, which you can read about in the topic which this one you're reading follows on the heels of; but I must not give you the link, as that would surge the views of it, and some people would get upset... Find the link in the first post...

Which first post of this topic will be expanded with some more necessary details only when no shadow of doubt is left as to authenticity of the event of the apparent Moz cloud autodownload into my machine, non-decryptable for me, the user, having happened when I claim, by the virtue of the traffic dump and the screencast being verifiable to have been taken when I posted that first post in this topic)

Which first post of this topic will be expanded with some more necessary details when more views, by different viewers, dispell any shadow of doubt in the authenticity of the traffic dump and screencast.

And only then can I also change the title of this topic to "Mozilla Cloud non-Decryptable Download?"
)

Regarding my post to Mozilla dev-security ML, let's see if I get any info back...

All is in the:

and I checked it by downloading it. Sums are right, and digitally verified with my PGP signature...

I'm not letting go of this. I'll try and ask on Wireshark ML, if I don't get any replies from Moziila devs. I mean any real replies...

The last reply, so far, is so general, and so dry... So hitting-oneself-in-the-mind's-eyes and beating-ones-brain to churn out a dry-kind empty reply... that it makes me sad.

Looks like really this is some abuse attempted on my machine, from Mozilla Cloud addresses.

But... Before I change the title; which is not yet, too few views, at which time I can take the opportunity to say it more forcefully, right there upfront and very clearly in the first post...

Which I can not edit, the first post, yet, because of the shintilibidintitty "advice" there posing like a thought exudision...

Before that, I am advising readers who wish to understand what this is about, that they need to study the link given upfront, else they can not figure this issue here at all...

Again, get familiar with this:

SSL Decode & My Hard-Earned Advice for SPDY/HTTP2 in Firefox
https://forums.gentoo.org/viewtopic-t-1029408.html

else you can not understand here.

There could be the solution on the way, and the autodownload couldl be legitimate.

I got a kind reply by Andrew Sutherland:

https://groups.google.com/d/msg/mozilla.dev.security/abSHPU4EaP8/9NitJEGICAAJ

More work for me... as usual, at turtle-speed.

Over in a new topic of mine:

(which I can not change the subject of the topic into the one above yet, for reasons easily understood if you read there)

I had posted this:

I recently wrote:
Not sure at all what this will come out.
Code:

I make make un unrelated post (planned previously) out of this.

However, if this is something interesting (just take a look at how interesting this topic of mine

SSL Decode & My Hard-Earned Advice for SPDY/HTTP2 in Firefox
https://forums.gentoo.org/viewtopic-t-1029408.html

appears to be; currently3498 views), it is important that the files don't be easily dismissed as unauthentic.

Patience, I kindly ask of readers.

and before you know it, there was this reply:

miro ... yes, and if you include a URL in every post you make (as you do) then crawlers will harvest those links, and so the views increase ... isn't technology amazing. Your posts, this one especially, are esencially nonsensical, and you seem to be under the impression that people are reading.

best ... khay


Now, since I do not want to disturb that topic... It has been sufficiently disturbed by that khayyam's remark, and since I am a little sick of such topic-pooping, I want to post a few words about it here, not there.

Because this topic (the "Uninstalling dbus and *kits (to Unfacilitate Remote Seats)" is over, technically.

It is technically over, this topic. There is little technical to add about it, other than start a new topic.

But that one is NOT.

But I will write a few more words about it, when I find tine... Because on top of the fact that I work at turtle-speed even at my best, I've also been working at only 10-20% effectiveness, and that only when I managed to get out of bed. Just allergy, but a very very disruptive one...

I'll try and explain why exactly here, I want to post. But it is in brief: this khayyam guy just can't get over our little clash that we had here, and to understand why he decided to try and poop out that new topic of mine, it is necessary to remember what happened here btwn me and him.

Just go back to my, I think, second previous post of mine in the third (first previous) page of this topic:

<this same topic>
https://forums.gentoo.org/viewtopic-t-992146-start-50.html#7661780

miro ... more nonsense, its not like everyone (steveL, krinn, and many others) haven't said the exact same thing, so, no, I'm certainly "over" it (whatever that "it" happens to be in your imagination). If you have a problem with the post, or my previous posts, then use the 'report' button.

miroR: Please stop bumping this. A good half those views are from myself and other moderators wondering what to do with it. They are NO indication whatsoever of the quality (or lack thereof) of the topic. And by you posting here, this thread's count wil go up by a few 100 as I, others, and a myriad of Google/Bing/Alibaba/etc bots all come around to see what's new and index it all. And, by my posting this, the count here will go by a bunch more. Did you know that if you view your own thread, the count goes up? Wheee! let's play the game, can we make it to 9000?

You have been warned.

Locked.
