> I bet you could use a CR1216 battery (1.6mm thin, 30mAh, instead if 34mm long and 1500mAh) instead and have quite a good deal of spare volume in the battery for an explosive.

I'd be fascinated if that was the physical vector...

However, tainting a component pre-integration seems a lot more likely than simply packing explosive in the case.

Israel inserts the compromised components upstream in the supply chain, they're duly assembled into pagers, which then make their way to Hezbollah, where they're inspected, look normal, and work normally, and are then distributed.

That would still require a firmware hack to presumably trigger though (incoming message stack to component trigger).
