A report published late this afternoon reveals that Apple asked a court on Friday to dismiss its three-year-old hacking lawsuit against spyware pioneer NSO Group, arguing that it might never be able to get the most critical files about NSO’s Pegasus surveillance tool and that its own disclosures could aid NSO and its increasing number of rivals.

A redacted version of the filing in San Francisco federal court cited a July article in the Guardian, which reported that Israeli officials had taken files from NSO’s headquarters. The newspaper said the officials asked an Israeli court to keep the action secret even from those involved in an earlier, still-pending hacking suit against NSO filed by Meta’s WhatsApp. Israeli ministry of justice communications that were hacked showed that officials were concerned about sensitive information reaching Americans, the newspaper said.

“While Apple takes no position on the truth or falsity of the Guardian Story described above, its existence presents cause for concern about the potential for Apple to obtain the discovery it needs,” the iPhone maker wrote in its filing Friday. Israeli officials have not disputed the authenticity of the documents but have denied interfering in the U.S. litigation.

NSO lost its own bid to dismiss the case in January. The company raised a raft of defenses, blaming Apple for shipping vulnerable software and allowing criminals and terrorists to communicate in secret.

While NSO will likely welcome the suit being dropped, Apple and some of its allies said it came about in part because of NSO’s decline. To read more on this story, view the full report on The Washington Post.
