The Post has more details about the pagers that the Mossad blew up, injuring thousands of Hezbollah terrorists:
As an act of spy craft, it is without parallel, one of the most successful and inventive penetrations of an enemy by an intelligence service in recent history. But key details of the operation — including how it was planned and carried out, and the controversy it engendered within Israel’s security establishment and among allies — are only now coming to light.
The idea for the pager operation originated in 2022, according to the Israeli, Middle Eastern and U.S. officials familiar with the events. Parts of the plan began falling into place more than a year before Hamas’s Oct. 7 attack that put the region on a path to war. It was a time of relative quiet on Israel’s war-scarred northern border with Lebanon.
Mossad, the Israeli intelligence service responsible for combating foreign threats to the Jewish state, had worked for years to penetrate the group with electronic monitoring and human informants. Over time, Hezbollah leaders learned to worry about the group’s vulnerability to Israeli surveillance and hacking, fearing that even ordinary cellphones could be turned into Israeli-controlled eavesdropping and tracking devices.
The United States, Israel’s closest ally, was not informed of the booby-trapped pagers or the internal debate over whether to trigger them, U.S. officials said.
Via Bruce Schneier, security researcher Bunnie Huang does not think this was a good idea in the long run:
The reason we don’t see exploding battery attacks more often is not because it’s technically hard, it’s because the erosion of public trust in everyday things isn’t worth it. The current discourse around the potential reach of such explosive devices is clouded by the assumption that it’s technically difficult to implement and thus unlikely to find its way to our front door.
I would posit that a lithium battery constructed with a PETN layer inside is largely undetectable: no visual inspection can see it, and no surface analytical method can detect it. I don’t know off-hand of a low-cost, high-throughput X-ray method that could detect it. A high-end CT machine could pick out the PETN layer, but it’d cost around a million dollars for one machine and scan times are around a half hour – not practical for i.e. airport security or high throughput customs screening.
now that I’ve seen it executed, I am left with the terrifying realization that not only is it feasible, it’s relatively easy for any modestly-funded entity to implement. Not just our allies can do this – a wide cast of adversaries have this capability in their reach, from nation-states to cartels and gangs, to shady copycat battery factories just looking for a big payday (if chemical suppliers can moonlight in illicit drugs, what stops battery factories from dealing in bespoke munitions?). Bottom line is: we should approach the public policy debate around this assuming that someday, we could be victims of exploding batteries, too. Turning everyday objects into fragmentation grenades should be a crime, as it blurs the line between civilian and military technologies.
I fear that if we do not universally and swiftly condemn the practice of turning everyday gadgets into bombs, we risk legitimizing a military technology that can literally bring the front line of every conflict into your pocket, purse or home.
Excuse me while I shove my phone across the desk...just a bit farther away...
