SFT-Loader with FritzBox sniff!

Who knows the "SFT-Loader", not just when it comes to legal downloads is not quite of this highly regarded tool.

"The task of the SFT Loader is primarily there to stop the direct link of download sources somewhere else (known as Linkstealing)," it says on the homepage of the developer .

Protected by encryption and Sniffer Detection

The approach that the developers have chosen (the encryption of links), but has a big disadvantage, because there are still all unencrypted data sent over the network.

So far what I thought, just because the tool has a built-in sniffer detection, the sniffer detects all the mainstream that one of the "SFT-Loader" but can confidently entrust their links.

FritzBox shows FTP files and directories

One method to circumvent this whole local Schutmaßnahmen is obviously a step into the network. So far, we still needed a second PC, since they act as a gateway between the Internet and had to ask to read the network traffic.

But this time is over now, there have been such a router are the functions implemented. So it might appear as the AVM Fritz box, where you can be in the web interface a recording of all data that have gone on the Fritz, download.

Course are in the process and the data in one download per SFT file (*. sft), and one can now handle it as you wish.

Warning on foreign networks

From this one can only learn that you can not be too careful. Until now, such a recording FritzBox can not store it locally, not far away, this time at today's price declines to be more.

In the future, one must carefully observe even more aware of what it sends its data to the network.

Welcome encryption!

This insight should be smaller, not an invitation to the DELETE (which I own in any way Eighth / cheap), but a glimpse of what all is possible with today's technology and what you should be prepared: PS.

As a note to the topic we want to note that the SFT Loader does not send the data unencrypted on purpose, but this requires the protocol.
Here, the administrators are asked to extend their FTP and Web server with SSL support, and to use them. Only this also carries with it an encrypted transmission and the associated high security.


Well, I thought that goes out from my post, that only an encrypted connection is a secure connection.

It should rather be just shows that it does not matter what you do with the links always open to everything is transferred.

The SFT-Loader held forth here as an example because it's currently one of the most used tools in this area.

I did not make it bad!

Under which menu item in the web interface of Fritzbox should that be? I'm too lazy namely NEN gateway to integrate. In what format are available as the sniffed data? And with what tool I can analyze them? I have my box not "hacked" - is still useable then (after all, is the Web Interface, or)?

greeting me


The point is linked to the web interface (namely web interface).

The files are available in Ethereal format. These files can use the tool Ethereal or Wireshark to the newer version can be read. Whether this may also have other I do not know in any case, both versions are free.

Your statement about Gateway, I'm not completely understood. It looks at you like that? This is used only as a modem or the Fritz as a gateway? Because to record my view, the box must be entered as the gateway, can order.

PS: No, the box has all these functions at the factory and must not be "hacked" his.


Ok super habs I understood, I just stumbled upon it after the login in the menu is ordinary and not as hoped for in the menu package being recorded. So thanks again. That was the only gateway to the relative I had no desire to set up a computer with two interfaces. Now will work that way too:).

Hello.
I've found a slightly different, possibly more elegant method. What do you think?
