In a previous blog post, I shared early details about the Hezbollah pager explosions and promised to provide an update as more information became available. Today, I’m delivering that update, based on Reuters' recent investigative report. You can read their detailed article here.
The event, which unfolded in September, involved thousands of pagers distributed to Hezbollah members that unexpectedly exploded across various locations in Lebanon. This operation is believed to be a prime example of a new era in espionage, combining deception, advanced technology, and precision targeting. While no one has officially claimed responsibility for the attack, the technological complexity suggests that this was not an ordinary act of sabotage.
Operation Overview: The Technology Behind the Attack Hezbollah’s choice to use pagers stems from their attempts to circumvent traditional communication surveillance. Mobile phones have long been vulnerable to interception, especially with the advent of sophisticated signal intelligence. Pagers, considered a lower-tech option, were seen as more secure by Hezbollah, a decision that turned out to be tragically flawed.
According to Reuters, the AR-924 pagers, procured earlier this year, were far from ordinary. The devices, supposedly manufactured by Taiwan's Gold Apollo, contained hidden explosives embedded within the lithium-ion batteries, a method that rendered them indistinguishable from standard communication devices. The unique feature of these batteries was their ability to store only a third of the typical capacity for a battery of similar size. This limitation arose from the space required to store six grams of PETN, a powerful plastic explosive, within the battery casing.

PETN (pentaerythritol tetranitrate) is one of the most potent explosives used in military-grade munitions. Its incorporation into these pagers allowed for the creation of a highly concealed yet devastating weapon. PETN’s low sensitivity to shock or friction made it the perfect choice for this type of operation. Only an electrical signal could trigger the explosion, meaning the device remained stable and undetectable until the moment of detonation.
The Masterful Deception: How They Fooled Hezbollah What sets this operation apart is not only the technical ingenuity but also the sheer scale of the deception involved. The success of the attack relied on convincing Hezbollah to adopt these pagers en masse. This was accomplished through an elaborate backstory created around the product.
To ensure the devices appeared legitimate, agents built an entire network of fake companies, online stores, and marketing collateral. The Apollo Systems HK website played a crucial role, presenting itself as an authorized distributor of Gold Apollo products. The website was so well constructed that even Hezbollah’s stringent procurement team failed to detect any discrepancies. From fake catalogs to online stores selling the specialized battery, the operation was designed to withstand even the most cautious scrutiny.
In fact, two fake online stores listing the LI-BT783 battery as a purchasable item were critical in making Hezbollah feel secure in their decision to acquire these pagers. They even passed the organization’s security checks, which involved scanning for explosives at airports. Mossad—or whichever party was responsible—knew that the complexity of the operation required not only technological sophistication but also psychological warfare. The backstory needed to be bulletproof.

Further aiding the deception was a promotional video uploaded to YouTube in late 2022. This 90-second clip showed off the pager's supposed benefits, including its long battery life and USB-rechargeable feature. The technical details of the battery, which did not exist in commercial databases, were faked with impressive attention to detail, ensuring that Hezbollah could not find any red flags during its due diligence.
Technical Breakdown: The Lethal Design The technical details behind the lethal design of the AR-924 pagers are remarkable in their precision and innovation. From a technical standpoint, the battery—model LI-BT783—was engineered to perform dual functions: powering the pager and concealing a deadly payload. This battery, weighing around 35 grams, was expected to have a capacity of 8.75 watt-hours, but it was reduced to just 2.22 watt-hours due to the explosive PETN hidden inside.

The key to the device’s functionality was the careful layering of lithium-ion cells surrounding a thin sheet of PETN, totaling six grams. This explosive material was strategically placed so that the battery would appear operational during use but was capable of detonating with a small electric charge. PETN is extremely efficient in confined spaces, making it the ideal choice for this operation. Additionally, the battery’s internal structure ensured that it would pass standard airport security screenings without detection.
Creating such a lethal design required careful consideration of the battery’s behavior under real-world conditions. According to battery safety experts, the energy capacity of the LI-BT783 was cleverly manipulated to balance between operational functionality and housing the explosive. The lithium-ion cells provided enough energy for short-term operation, which reduced any suspicion that might arise from a rapid battery drain, while the explosive could remain undetected inside the battery's casing.
The trigger mechanism, likely a remote signal or timer, activated the PETN, ensuring that the explosive could be detonated at a specific time across multiple devices. This simultaneous detonation proved devastating when thousands of pagers exploded in Hezbollah’s possession.
The Moment of Detonation On September 17, 2024, Hezbollah’s secure communication system was shattered. Thousands of pagers beeped simultaneously across multiple locations in Beirut and Hezbollah strongholds, mimicking the receipt of a new message. Fighters and medics alike instinctively reached for their pagers just as they exploded, causing significant casualties and sowing panic within the organization.
Footage reviewed by Reuters shows that the explosions were small but precise, designed to harm those closest to the devices. Hospital footage shared on social media revealed victims with severe injuries, including missing fingers and facial wounds, consistent with the placement of the pagers at the time of the blasts.
The Aftermath: Hezbollah's Internal Chaos While Hezbollah initially suspected the pagers’ rapid battery depletion to be a minor issue, they continued to distribute the devices up until hours before the attack. The subsequent explosion led to an immediate investigation within Hezbollah. However, this was soon disrupted when Nabil Kawak, the high-ranking official leading the internal probe, was killed in an Israeli airstrike less than two weeks after the explosions. This assassination has left Hezbollah scrambling to piece together the full extent of the breach.
Conclusion: A New Chapter in Espionage This operation, meticulously uncovered by Reuters, represents a high point in modern espionage. While no party has claimed responsibility for the attack, the level of technological and operational sophistication suggests that this was not an ordinary intelligence mission. The creation of an entirely fabricated product, complete with marketing materials and a detailed backstory, reveals the extent to which espionage has evolved in the digital age.
The Hezbollah pager explosions are a reminder that technology, once viewed as a tool for communication and coordination, can be turned into a weapon of devastating precision. As we move further into an interconnected world, the risks associated with even the most mundane devices will continue to rise, posing new challenges for intelligence and security agencies alike.
This story continues to unfold, and as more details emerge, I will provide further updates. For now, this operation serves as a case study in the power of deception, precision, and advanced technology in the world of modern warfare.
