The risks of malicious trackers.

Malware can do anything, but malicious hardware can do even more.

Yes.

I’m assuming by “built-in tracking device” you mean that someone has actually added a hardware device of some sort to your laptop.

Such a device would share all the capabilities of malware and perhaps even more.




As a general rule, malicious software, or hardware, can do anything, at any time, as you use your computer. Malicious hardware, specifically, can evade detection and persist no matter what you do, until the hardware itself is removed. Running tools like Tor adds no value, as malicious hardware could potentially see every keystroke you type, everything displayed on your screen, and access any and all information kept on your computer, including your browsing history.

Malware can do anything

Once malware is on your machine, it can do anything.Tweet this! That’s one of the reasons prevention is so critical.

The addition of hardware to your machine is no different. Be it a physical keystroke logger or a device that monitors your CPU activity in some way, it has the exact same capability: it can do anything.

Chances are it could do more than traditional malware. I can envision a tracking device installed on your laptop that is relatively impervious to detection, for example. Anti-malware tools don’t look for rogue hardware, so it would be unlikely to be found.

Using Tor on your computer

TorThe Onion Router — is a privacy and anonymization service that allows you to hide your internet activity in two ways:

  • The sites you visit have no idea who you are or where you come from (unless, of course, you explicitly tell them).
  • The path that data travels between your computer and that site is also impervious to detection, cementing your inability to be located.

What Tor doesn’t do, however, is hide your activity from your own computer. When you think about it, that makes no sense —  to use Tor at all implies using your computer to do so.








Related questions

Does Tor browser hide history?

The Tor browser keeps no history after you close the browser, effectively hiding your browsing history. It’s important to realize, though, that while Tor is running anything you do — including the sites you visit and the information exchanged with those sites — is potentially visible to malicious software on, or hardware attached to, your computer.

Is the Tor browser secure?

The Tor browser is only as secure as the machine on which you’re running it. While it provides abundant security across the connections it makes — hiding both your location, and what you are viewing — it relies on your machine also being secure locally. It cannot make an un-secure machine secure.

Can police track Tor?

In general, no, the authorities cannot track you through Tor, even though television and movies might have you believe otherwise. The most important exception is police or state-sponsored malicious software or hardware being present on the computer you’re using. With malware present, anything and everything can be tracked.

Can your ISP track you on Tor?

In general, no, your ISP cannot track you on Tor. It will see only that you are connecting to a node in the Tor network. Anything that happens across Tor is opaque and unseeable to anyone with the ability to snoop on your connection, including your ISP.

Traditional bypasses are ineffective

One of the traditional approaches to using Tor (or any privacy and security-centric solution), is to never assume that the installed operating system is trustworthy. Instead, one might boot from an optical disc that can’t be compromised, or a USB device you’re certain has not been. The result is to run a custom, perhaps single-purpose, operating environment.

For example, if you’re concerned about malware on your machine, you might boot from such a disk in order to perform online banking.

If you have malicious hardware installed on your machine, however, that approach is ineffective: the hardware is still there. It can continue to do — and monitor — anything.








It’s rare, but…

Now, you might think that someone actually going through the trouble to install malicious hardware on your laptop or desktop computer is highly unlikely.

And, unless you’re some kind of high-value target, it almost certainly is.

However…

This is one reason I’ll never use a shared computer (such as at an internet cafe or a library) for anything even remotely personal. One of the simplest devices to install would be a malicious keystroke logger. It would be virtually undetectable.

If you can’t trust the hardware, don’t use it

And that’s the bottom line: if for some reason you have cause not to trust the hardware, don’t use it. That’s the only pragmatic way to avoid the risk you seem to be concerned about.

Since this type of compromise requires physical access to your computer, the only step to prevent this from happening at all is to always and completely physically secure your machine when it’s not in your possession.

Assuming you think this is likely to happen to you, of course. Maybe you are a “high-value target” to someone after all.
