Based on SMEX’s analysis, three scenarios could explain what happened today.
Tampered devices
It is possible that the exploded pagers were part of a shipment that had been tampered with during transit. For example, small explosive devices could have been planted in them and remotely activated or set to detonate via a timer.
Overheated batteries
The pagers were not intercepted, but Israeli intelligence may have developed a way to exploit a vulnerability in the devices, potentially causing them to overheat and leading to battery explosions.
Explosions activated through radio waves
The pagers that exploded might have been tampered with during shipping (a supply chain attack), and later activated through radio waves emitted from a ground station or an intelligence device (such as an Airborne Warning and Control System, AWACS) to detonate the devices.
I highly recommend reading the SMEX article as it contains their full explanation for various questions.
What a bizzare situation. I wonder if we will find out how it was done. Because if this was just batteries.. that's really scary. But I expect there where explosives involved.
In their article on reasons for use smex omits that they cannot be traced as they do not send data, only recieve. Which is why they are used by terrorist organisations.. no risk of being tracked.
Based on the videos I've seen, I don't think it's just batteries. Li-ion batteries don't really explode, they burst into a lot of flames and stay burning for a while.
Yeah agreed, battery fires go with lots of flames and smoke. Especially the video of the guy that had it on his desk.. multiple holes no enormous fire.
Based on the latest this morning, these were devices manufactured by someone mysterious (Israeli intelligence) and just licenced to use a known brand name through a shell company in Budapest. They presumably had a small explosive charge built in.
