IEDs created from pagers and walkie-talkies and reports of exploding solar-energy systems herald a possibly limitless front in future war, where everyday items can't be trusted.

Why it matters: Supply chain warfare is here to stay. And the targets are soft.

• Blowing up factories and raiding supply lines is nothing new. What's unprecedented here are the spy-thriller-style backdoors and execution.

Driving the news: Fresh footage is streaming out of the Middle East, providing a closer look at attacks attributed to Israel. Yesterday, one clip showed a device blowing up in a market, incapacitating a person and spooking passersby.

• Hezbollah said the casualties — at least 8 killed and thousands more hurt — included many members of its military units and institutions.
• The detonations inside the group's strongholds will psychologically cripple its fighters as well as paralyze command and control. That suggests the boobytrapped tools were meant to preempt a broader conflict.
• It's a military truism: If you can't talk, you can't win. Hezbollah adopted low-tech tools to evade such deadly compromise.
• Separately, Lebanon's official news agency reported that solar-energy systems exploded in several areas of Beirut.

What we're hearing: Experts Axios consulted said the pager attacks are likely a mix of physical sabotage and cyber exploitation.

• One person said comparisons to Stuxnet, the first publicly known hack to cause real-world damage, were not on the money.
• Hiding explosives in electronics is one thing. Making them go boom from afar, and in sync, is another.

Zoom out: The specifics of this attack are unique to Israel's intelligence capabilities and to the financial and logistical limitations of a group like Hezbollah.

• Put simply, the Pentagon is unlikely to buy thousands of C-4-laden pagers for top brass.
• The wider concern, of course, are products sold to the public.

What's next: These attacks will be globally scrutinized. They will drive new calls for supply chain surety, as dependence on foreign parts kneecaps military prowess.
