This is not a hoax and is not a mistake.

The incident happend at different web pages that had been accessed before
many times without any incident.

The Zemana is the same version I am running since December 2013, i.e., it
is running for around 8 months without any incident.

Ar regular sites at the surface web that is accessed by many TOR users.
Sorry, I can not provide more specific information that may facilitate my

Again... I am using the same Zemana version for around 8 months without
any incident and acessing the same web sites.
So it is not a canvas access problem.
I will be very surprice if any web site is capable to generate such alert,
especially without to be able to run any script.

If both links are broken this means that somebody is doing a big effort to
prevent the file access.

The reason I uploaded to hosts is because the Tor Project team blocked my
attempt to send as attachment to this list.
By this you may also understand that the Tor Project team was aware about
my report two days in advance than the list members.

The uploaded file is a ZIP with a number of JPG images inside. As far as I
know both file types are safe.

I did a new upload to a popular JPG hosting service. Here they are:

My report with detailed information including the Zemana log showing that
firefox.exe tried to record my screen seems to be a very good evidence.
What more one may provide? Is somebody expecting a NSA or Tor Project
written confirmation?

Why will USA fund the development of a tool that can be used by its enemies?
You may have a doubt about the Tor backdoor. I don't.

What we have here is very simple: who pays gives the orders!

I guess inside the rerouting net is a kind of automatic tool to spy Tor
users and, in addition, the (humans) operators my pick users at will for
additional checks. Just my guess.

The Tor Project team is already working to resolve... keeping total
silence until everybody forgets my report with, for me a PROOF, for
everybody else an EVIDENCE, that TOR was spotted in flagrant while trying
to record my screen.

I am not connected with the message with subject "Third-parties tracking
me on Tor".
I paid attention on it too. Strange to have an ambiguous message send to
the list exactly one day after my first try (blocked by Tor Project team)
to report to this list.

I am not trolling this list.
I am providing serious information.

Do not seems that is the case otherwise the Zemana alert would be
generated on regular basis.

Oh yes, we will see many "news and leaks" reporting the "efforts" of NSA
and GCHQ to break TOR and bla-bla-bla.
Just desinformation to keeps the TOR credibility.

While may (or may not) provide some protection against USA enemies, TOR
provides NO PROTECTION against USA and friends.
TOR is a spy tool to spy on YOU!

Hope more users will start to use Zemana and other anti-spyware and more
reports about this problem arrives.
