Essentially the exact approach you propose has been attempted in far cleverer ways, it did not work very well.

> you would have to extract the keys from the malware

Yeah? That happens all the time. If you're designing mechanisms like this, it's presumably specifically against adversaries which are doing exactly that.

> you would then have to implement the logic and announce it - then rely on blockchain exploreres actually using that data to block addresses in real time.

Someone would only have to do this once and all your bots would be gone.

Usually the whole point of these mechanisms is C&C resilience, and usually that only matters for really big botnets which face co-ordinated attacks.

Any good C&C system for a bigger botnet would seek to eliminate all meaningful external points of failure for C&C. Using a block explorer, or HN comments, does not achieve that.

I mean, even just shipping a Tor client embedded in your malware seems like a much better idea.

>just rely on explorers to query your own wallet

This kind of defeats the point, you get exactly 0 censorship resistance like this.

Not unique to a person

> email address, phone number

Also often not unique to a person, although email addresses probably tend to have much longer lifespans as identifiers than phone numbers.

If the idea is to have a true opt-out system, it's really really difficult to implement given how these systems work.

If you look at the data provided by services like accurint, you'll frequently see the same SSNs used for decades by multiple different individuals, often with IDs from different states with the same name and DoB despite obviously being different people. With how the system works in the US, it can often be impossible for anyone to determine which physical person the SSN was actually originally assigned to.

Same obviously applies to other identifiers you suggested, but even the seemingly good ones are not very good at uniquely identifying people.

Given that most ccTLDs live in different jurisdictions, that's not really a huge problem.

Why would you want to use blockchains for this? DHT has been used for distributed c&c for ages and is generally a much lighter option.

But no, P2P C&C is still not really typical. In practice, there's mostly not that much need for it. Also, FWIW, for practically all use-cases P2P C&C discovery is a vastly better option.

Oh wow, we're in 2026 already.

Based on the pictures of the car, I can't even imagine how you'd get the car stuck there, much less get stuck inside the car.

This was a rural area, but he was a few hundred meters from a big road. Surely he could have just exited the car and walked there.

Even if you can't pull the modem or the sim card (less common now) directly, you can certainly always find and disable the antenna connection.

Any decent shop will be able to do this for a reasonable price.

So what? That's not very useful when getting said oil out of the ground costs more than you can sell it for, is it?

I've never seen an antenna that was difficult to disconnect, on the super simple end you have something like the W222 where you can literally just pop out the antenna cover on the roof and just remove the antenna module inside.

>But this is usually not without consequences as well such as a perpetual error code display or the radio, navigation or entertainment functions stop working.

Well sure, I do have cars without GPS because I was lazy. Carplay still works fine, so can't really bother to do anything about it.

Removing network connectivity from basically any new car is trivial, often as simple as pulling an easily accessible fuse.
