Palantir software was used by Israel in its 2024 pager attacks in Lebanon, according to a new book by Alex Karp, co-founder of the Palantir tech company.

On 17 September, thousands of pagers belonging to Hezbollah members, including civilians not involved in any armed activity, were detonated across Lebanon.

Many showed "error" messages and vibrated loudly prior to exploding, luring Hezbollah members or, in some cases, their family members to stand close by at the point of detonation.

The next day more communication devices exploded, including at the public funerals of Hezbollah members and civilians who had been killed the previous day.

While many Israeli figures celebrated, praised and even joked about the attacks, United Nations experts called them a "terrifying" violation of international law.

In total, 42 people were killed and thousands wounded, many left with life-altering injuries to the eyes, face and hands.

Karp's new biography reveals that Israel deepened its use of the company's technology after it launched the war on Gaza in October 2023, deploying it in numerous operations.

"The company's technology was deployed by the Israelis during military operations in Lebanon in 2024 that decimated Hezbollah's top leadership," wrote Michael Steinberger, author of The Philosopher in the Valley: Alex Karp, Palantir, and the Rise of the Surveillance State.

"It was also used in Operation Grim Beeper, in which hundreds of Hezbollah fighters were injured and maimed when their pagers and walkie-talkies exploded (the Israelis had booby trapped the devices)."

He said that the demand for Palantir's assistance by Israel "was so great that the company dispatched a team of engineers from London to help get Israeli users online".

Palantir tech used in Palestine

The involvement of a range of tech companies in Israel's attacks on its neighbours in recent years, as well as for attacking and surveilling Palestinians, has sparked anger from rights campaigners and UN officials.

In a report produced by UN Special Rapporteur Francesca Albanese in July, several tech companies were accused of profiting from crimes including illegal occupation, apartheid and genocide in occupied Palestine.
