Recent news was US and other agencies trapped and arrested criminals all over the world after selling them backdoored communication equipment some years ago.
In my opinion the best security device is the one you invent and make yourself. An example: Some years ago, after publicity about the hidden communication capabilities of USB storage devices, i made a USB device that allows me to safely transfer data across the air gap we have between production and web. E.g. an Arduino type thing that you can make within a week. This is nothing cryptographic but it is safe with a very restricted set of supported actions and with monitoring of those actions. Of course i won't explain any details and even the term Arduino is probably misleading..
I think you can easily beat others using your special capabilities.

I thought the most interesting part of that story was the confirmation that the FBI and other US agencies outsource monitoring of US citizens to other countries that they cannot legally perform themselves.

Fraser:
A word of advice....

if you find yourself under the surveillance of a countries Government, do not try to 'get smart' (stupid?) with them. You will most definitely regret such action. If a Government agency wants to monitor you, they will, simple as that. If you attempt to prevent them doing so, you will become of greater interest as well as an annoyance to them and your life will become far more 'complicated'.

Feel free to ignore this advice but remeber you are in their 'back yard' and you would be ill advised to mess with Government agencies. It is best to make yourself of little or no interest to them rather than try to be 'smart'. You will not win, no matter what you do ;)

And remember…. This is not a ‘game’ and poorly considered actions can have unforeseen consequences.

Bicurico:
Honestly? I think you are being just paranoid.

Who cares if you cloned PayTV smartcards (technically it was not clonining, but using the keys on an emulator written for some smartcard with embedded PIC or Atmel chip). Been there, done that (not commercially, though). By the way, this has been replaced with a newer technology called "card sharing". Go to AliExpress and search for CCCAM subscription. You will be amazed how cheap it is to have most PayTV packages open for 3, 6 or 12 months...

The other pranks? Mainly harmless. I did not mess with computers of public services, but I did mess with the computers on the University. One of the hacks was to invert the keys for the original DOS based Tetris game: the teachers were quite increadulous seeing students "working" with the keyboard flipped 180 degrees!

What I mean is: I doubt your past has the slightest interest for any democratic or dictatorship regime.

I would either bet that you are suspicious for being a US citizen!

Also, I don't think your small computer lab with IoT focus has the slightest interest for any intelligence agency. Who cares about what you do with your Arduinos and Raspberry Pies.

As long as you are not setting up a propaganda mesh network in Laos capital, of course.

And yes all the gear you describe is prone to failure and misfunction, especially in tropical environment. Note that Arduino and Raspberry Pi (and alike) are NOT certified for industrial use.

Finally, if you want to know what is going on, just install and run Wireshark to monitor your network traffic.

If you really require more than that and if the secret service is really spying on you, you must be doing something highly illegal (in the eyes of the regime) or their secret service simply sucks big time.

EDIT: And I do agree with Fraser. You better think if you are indeed not doing anything offensive to the regime. If not, let them spy. open the doors to them. If you might be doing something offensive, get the hell out of there.

Regards,
Vitor

It is my duty as a patriotic citizen to waste as much of their time as possible.
