    Here’s your detailed tech possible explanation with citations:

    Pagers known used in the attack were Apollo Gold AP-700, AP-900 and AP-924, which all use the same ALA25 programmable logic chip.

    If you google the Gold Apollo AL-A25 Programming Manual and look for battery gauge inputs, you can see it is possible to program the voltage ranges.

    By setting the battery gauge level-high to an invalid selection that is also greater than the low level it creates a bridge between the anode and cathode, resulting in thermal runaway which will in fact cause the battery to overload and explode due to the increased temperatures.

    We’ve done this using similar batteries on battery backed write cache controllers sitting in a nema-3 enclosure just to see what the tolerances are.

          First part of this is gibberish. Second part is just describing a short of the battery, which will destroy it, but is completely inconsistent with video footage which shows small high explosive charges going off. That is not how battery shorts happen. This was not done in software, there were actually explosives installed in the devices as reports are starting to now state. But you know, good job on the sheer volume of words you wrote.

            Surprised you responded, I’ll respond back later when I get home so I can share the level of detail it is I am talking about.

              Nothing you say will make a lithium ion battery into a high explosive. There is no combination of words you can say that will make that true.

                So wait, you come storming in trolling fake bs fake. Then I come back with citations that I sincerely forgot, you then respond with zero evidence to the contrary to “educate me” and go out of your way to just shut down, cross your arms and pout?

                Yeah. really, sincerely, you have zero ethics.

                  Your citations aren’t relevant . Link dumping nonsense isn’t an argument. This attack was done through hardware manipulation, not merely software on otherwise normal hardware. Nothing you said even begins to refute that. There are millions of videos of Lithium Ion battery thermal runaway and none of them look anything like the videos of these pagers exploding. You’re just wrong. Take the L bruh.
