According to this recent article, the attack was planned by Israeli unit 8200. The article states that “The unit is famous for a work culture that emphasizes out-of-the-box thinking to tackle issues previously not encountered or imagined. This helped some graduates build Israel’s high-tech sector and some of its biggest companies.” The article quotes a former member of Unit 8200, Kobi Samboursky, who is now Managing Partner at Glilot Capital Partners, as saying, “The most significant thing here is the ‘can-do’ culture, where everything is possible.” https://www.activistpost.com/2024/09/exploding-pagers-kill-hezbollah-in-lebanon-why-we-should-care.html
