Iran’s Ambassador to Lebanon Loses One Eye, Seriously Damages Other in Pager Explosion, New York Times

Mojtaba Amani, according to the publication, is being evacuated to Iran for treatment. It is noted that before the explosion, the pagers emitted a beep, which prompted many to bring the devices to their faces.

The attack was probably carried out by Israeli intelligence services, which planted explosives in about 5,000 pagers, Reuters reports. Of these, about 3,000 exploded. A senior source in Lebanon told the agency that the devices were planted by the Israeli spy service “at the production level.” “The Mossad inserted a circuit board containing explosive material into the device, which receives a code. It is very difficult to detect by any means. Even with any device or scanner,” the source said.

The day before, 4,000 people were injured in Lebanon, 11 of whom were killed as a result of pager explosions. Reuters writes that hundreds of members of the Lebanese armed group Hezbollah, including fighters and medics, were seriously injured due to explosions of pagers, which they use for secret communication.

A second wave of explosions today

    I’m kind of guessing, from the strength of the explosion in the video – it really was a small explosion, not bursting into flames – that somehow rigged pagers were inserted into Hezbollah’s equipment prior to distribution to operatives.

    But if this was, instead, some kind of remote software compromise of battery management system firmware for lithium batteries, now I have one more thing to worry about in my life, with all the devices with lithium batteries I have.

    looks warily at laptop on my chest

    EDIT: Strengthening my concerns, in the CNN article I linked to in my other comment, the devices were termed “hacked” by Lebanese internal security forces. Now, okay, that’s a report immediately after the event, and I don’t know how much time they have had to actually do analysis. Or if they’re right. But:

    NNA reported that “hacked” pager devices exploded in the towns of Ali Al-Nahri and Riyaq in Lebanon’s central Beqaa valley, resulting in a significant number of injuries. The locations are Hezbollah strongholds.

    …it sure doesn’t assuage my concerns at all. Even if you couldn’t make a BMS discharge lithium batteries hard enough to explode, you definitely can make them do so hard enough to make a pretty unpleasant fire. You do that with numerous laptop-sized devices all over a country, that’d potentially be a pretty unpleasant event.

    sighs

    Maybe it’s possible to mandate that lithium-ion devices conforming to some sort of safety certification standard, like UL or something, have non-updatable-firmware hardware putting a physical limit on discharge rate. I don’t think that that’d add too much cost or too many restrictions to devices.

    EDIT2: From this YouTube video, it sounds like as long as you’re not using sketchy battery cells in the device you’re building, that battery manufacturers already take this into consideration via a blowout hole:

    Even in the event of a short circuit, genuine lithium-ion batteries have several protective measures to prevent them from catching on fire. Take a look at this lithium-ion that was just shorted out. In the unlikely case that a battery short-circuits, the terminals heat up and the electrolyte fluid begins to boil. The vent holes in the top of the terminal allow the battery to depressurize the electrolyte steam, thereby reducing the battery capacity and making a pressure explosion much less likely. In the end, you’re more-likely to see a small fire shoot out of a battery than a large explosion. While they still can cause damage, it’s a much better option than having a battery explode, which results in a shrapnel cloud. But in counterfeit batteries, this vent hole safety valve is often ineffective.

    All that being said, I wouldn’t be surprised if I have some devices with sketchy cells…but my guess is that at least in my collection, when it comes to large-battery-capacity, Internet-connected devices capable of firmware updates, stuff like laptops, they’re probably – hopefully – using legit battery cells.

      I don’t believe small lithium batteries can explode like that. Not even big car batteries explode like that. They make a big fire but not this kind of explosion.

      Either explosives were implanted somehow by IDF in the supply chain, or Hezbollah is crazy enough to put explosives there, just in case the devices fall in enemy hands, and IDF learned that and trigger the explosions remotely.

        Supply chain makes the most sense. It’s not like pagers are used super commonly and I doubt they have good margins. Would be pretty easy to sneak something in.

        The scary thing about a supply chain attack is that Hezbollah aren’t idiots. This is basically like buying a “burner phone” (that name will now have different connotations now).

        In the movies, people buying burner phones go to a random corner store and buy a random phone off the shelf. That way, even if they’re under surveillance, the cops / CIA / FBI can’t pre-bug the phone because they don’t know which corner store the person’s going to go to, let alone which phone they’ll pick off the shelf.

        If you’re an armed group in Israel’s crosshairs, you’re going to take similar precautions when buying thousands of pagers. The safe way to do it would be to slowly and unpredictably get a small sample of ones that are being sold to the general public. If this is true, it could mean that there are tens of thousands of pagers out there that contain explosives that were merely sold as “decoys” in order to try to make Hezbollah feel safe in buying them. In other words, there may be tens of thousands of explosives in pagers that weren’t activated because they weren’t in the hands of Hezbollah when Israel decided to hit the button.

        I don’t believe small lithium batteries can explode like that.

        If it’s an 18650, which is a pretty common small lithium cell, it looks like it can. Here’s one exploding after being shorted:

        https://www.youtube.com/watch?v=iDaPP-dI9dE

        That being said:

        • The cells cannot themselves have current regulation sufficient to avoid a fire or explosion. My vague understanding from past reading is that typically, if you buy an 18650, it’ll have internal regulation, but not all do – it adds to the cost and reduces capacity. But you’d only want an unregulated 18650 if you were putting it in a device that you would trust to regulate the thing. I believe I was reading about it in the past in the context of high-end flashlights that took removable 18650s, was telling people not to try and use unregulated 18650s, as then you’re trusting the flashlight’s firmware to properly limit the discharge rate.

        • The battery would have to be the first point to go if the external BMS circuitry just let the thing discharge as quickly as possible. Like, if you had small-enough connections or something, I’d imagine that they’d melt first, act like a fuse.

        • From the video I read above, lithium batteries from reputable manufacturers tend to have blowout holes to prevent exactly this – if the electrolyte starts to boil, then they’ll start venting vapor. They may catch fire from the heat, but it should prevent the pressure buildup from reaching the point where the battery explodes. They say that counterfeit cells may not have vents that work correctly.

        So I can believe that there are devices out there at risk. But I would guess that most devices probably aren’t. That is, you could maybe make devices catch fire, and that could be bad if done at mass scale at the same time, but probably most wouldn’t explode.

        Even on that above 18650 that exploded, you could see vapor coming out prior to the explosion. According to that video I linked above about exploding lithium batteries, it sounds like the issue is more that on some counterfeits, the pressure release system doesn’t work properly rather than that it doesn’t exist at all – I didn’t quote the text, but they went more into depth on it after the bit I quoted. But I suppose that if there were no presssure release at all, that it could probably get more pressure buildup before exploding.

          If the device in my pocket started smoking like that, I’d throw it away pretty quickly. I suspect these were actual explosives, and there are almost certainly more of them out there.

          You’re linking to an EV battery on the idea that a pager would use it?

            You mean an 18650? An 18650 is a small cell, in the neighborhood of the size of an AA battery, that is used in all kinds of electronics, including small consumer electronics. They can be used as a basic building unit for larger battery packs – if you take apart a lithium powerstation, you can probably disassemble it and find 18650s. It may be that some EVs build packs from 18650s, and I’m sure that ebikes will, but they aren’t specific to EVs.

              You’re right. The article I read had listed typical uses as EVs and personal mobility without saying anything about their size. Looking up actual pager batteries. I do see similar dimensions and similar weight, so it’s plausible they would explode similarly

                Honestly, I’m not saying that I’m sure that that’s what it is – I listed both sabotaging equipment before distribution and this. Just that it’s possible to make them explode, and you have the quote from the Lebanese internal security people saying that they were “hacked”, which would indicate that it’d be the battery, because nothing else in a pager can do that. They might be wrong, of course – it just happened and they cannot have had a lot of time to examine them.

                I don’t care all that much about sabotaged equipment – my electronics aren’t likely gonna have bombs built into them.

                I’m a lot more concerned about the possibility of weaponizing the BMS on devices with lithium batteries. Like, there are a whole lot of those out there, and a whole lot of parties who might want to attack other parties via that route. It’s not an attack vector that I’ve thought much about, but it’s a big enough one that I’m not entirely sanguine about having devices with God knows what security on their BMS floating around.

                Plus, the fire factor is honestly pretty bad on its own. Like, the explosion isn’t huge. Whatever the cause, in both the video I linked and the pager explosion video, we aren’t talking about a hand grenade or anything. Would really have to have the device on you for it to likely be a serious problem. But if you have some IoT device somewhere sitting around flammable material unattended, especially if lots of devices go off at the same time so that the fire department cannot respond to any one…shrugs That’s kind of a concerning thought.

      Israeli secret services used exploding phone previously, it’s not a stretch to assume that they tapped into supply chain of pagers and brought a pallet of pagers with a low tens of grams sized bomb inside

      also lithium batteries don’t explode like that

      I wonder whether they exploded exactly at the same time. If so, it seems less likely it would have been an attack via the batteries since you wouldn’t expect them all to heat up and explode at the exact same rate.

      Also, how many pagers are still out there with explosives in them?

      Option 1: Israel blew up all the pagers containing explosives, regardless of whether they’d been sold / passed on to family members, friends, or other people who had no connection with Hezbollah, so many of the thousands of injured were innocent bystanders.

      Option 2: Israel got the pagers into the hands of tens of thousands of people, then only blew up the ones that were actually in Hezbollah possession, leaving thousands of pagers out there containing explosives.

      Knowing Israel, it’s almost certainly option 1.

        these pagers were issued by hezbollah higher-ups, for one-way communication with their hq. there’s little reason for them to sell them or even lend to family because you can’t call from this thing or communicate with it any other way because it’s receive only. civilian casualties are probably low for this reason

          because you can’t call from this thing or communicate with it any other way because it’s receive only

          Yes, it’s a pager. Pagers are still useful, that’s why they’re still being manufactured and sold. Someone in IT who’s on call can have a pager set up so that an automated process sends them a notification if a system breaks. They don’t need two-way communication for that. A doctor can use one to be notified if they’re needed at the hospital. It’s more reliable than a cell phone and in many cases the battery lasts a lot longer. They could even be useful for a parent to give to a kid, so that the parent can get in contact with the kid and have the kid call home if something happens. In rich countries that could happen because the parent doesn’t want the kid using the device all the time to scroll TikTok. In poorer countries it could happen because a pager is much, much cheaper than a phone.

          The fact that thousands of these devices were exploded suggests that it was a pretty wide group of people who were using them, so the odds are pretty good that at least some of them were given away / sold.
