Pager and Walkie-Talkie Explosions Reveal Supply Chain Investigation

Deadly explosions caused by pagers and walkie-talkies used by Hezbollah in Lebanon have sparked an in-depth investigation into the origins of related products. This process shows that the market for these outdated technology products is very opaque and buyers often know very little about the products they are buying.wifi jammer

The Lebanese Hezbollah bombing of pagers and walkie-talkies that killed 37 people and injured about 3,000 people shows that it is very difficult to verify which link failed.

Taiwan's Golden Apollo accused a European company of licensing its pager brand, sparking investigations into the origins of related products in Hungary, Bulgaria, Norway and Romania.

How massive attacks took place simultaneously, injuring thousands

Time and place of the incident

The explosion occurred at 3:45 p.m. local time on Tuesday in Beirut, Lebanon's capital, and many other areas of the country.

Witnesses reported seeing smoke rising from people's pockets and hearing small explosions like fireworks and gunshots.

Surveillance video appears to show an explosion in the pocket of a man standing in front of a store cash register.

Reuters reported that explosions continued for about an hour after the first blast.

Soon after, many injured people flocked to hospitals across Lebanon, and witnesses everywhere reported chaotic scenes.

How do pagers explode?

It is possible that a hacker attack caused the pager's battery to overheat and explode. If so, the attack would be unprecedented. It is triggered by signaling, a form of so-called alphanumeric text messaging.

• Pagers can be modified to explode, typically by using them as radio communication devices to remotely trigger bombs.


• A pager is a device that receives radio signals and can receive wireless messages in a specific frequency band. An attacker could exploit this feature to control an explosive device.


• When the pager receives a specific signal, it can use internal circuitry to trigger a detonator connected to the explosive. This detonating device is usually a relay or switch that connects the explosive to the pager's power supply.

Attackers often choose frequency bands with wide coverage to ensure that pagers can receive the signal. Using signal jammers can block wireless signals in certain frequency bands and prevent pagers from receiving detonation signals.
