Another cyber warning has been issued about the risk from compromised chargers—but this time data theft is not the issue...
Hackers Can Now Trick Usb Chargers To Destroy Your Devices—This Is How It Works:
Not all cyber attacks focus on data theft. Sometimes the intent is "to achieve destruction of the physical world through digital means," Chinese tech giant Tencent warns. The company's researchers have just disclosed a serious new vulnerability in many of the mass-market fast chargers now used around the world.
[...] Tencent’s researchers have now proven that a compromised charger can override this negotiation, pushing more power down the cable than the device can safely handle, likely destroying the device and potentially even setting it on fire.
Because the fast charger is essentially a smart device in its own right, it is open to a malicious compromise. An attack is very simple. With malware loaded onto a smartphone, an attacker connects to the charger, overwriting its firmware and essentially arming it as a weapon for whatever plugs in to it next.
The interesting twist here is that the malware might even be on the target device. An attacker pushes that malicious code to your phone. The first time you connect to a vulnerable fast charger, the phone overwrites its firmware. The next time you connect to that same charger to [recharge] your device, your phone will be overloaded.
Tencent has produced a demo video, showing how a charger can be compromised and then used to overload a device.
Tencent have dubbed this issue "BadPower," and warn that "all products with BadPower problems can be attacked by special hardware, and a considerable number of them can also be attacked by ordinary terminals such as mobile phones, tablets, and laptops that support the fast charging protocol."

You shall not entrust a critical fixpoint of physically engineered structure to software.
There are places you shouldn't even trust a diode or a relay. You wanna be at the actual switch/valve

Can we still say "switch" or the trannies get offended?

Uh oh I am afraid the term "Just", subliminally reminding people of "Justice", can be used only if your skin's luma value is in the lower 75%. Do you qualify?
As for the dikes, is there anything a pair of dikes cannot achieve eventually?

Stretching wire. Generally, I need to use the wire stretches after too liberal applications of dikes.

If you can't have a baby, make friends with social services until they let you steal one. EZ

You can actually create a completely static construction diodic device in many physical domains:

This is kind of engineering I trust.
