•[ spyware, cyber espionage, pegasus ]
The article reports that the US Central Intelligence Agency used Israeli-made Pegasus spyware as part of a deception campaign inside Iran during an operation to rescue a downed American airman.

The piece says Pegasus enabled messages to be sent through apps like WhatsApp and Signal that looked like they came from compromised devices, helping mislead Iranian forces during the rescue effort. The report also says the CIA used a separate classified system called Ghost Murmur to locate the airman by detecting a heartbeat from a distance, though experts cited in the article expressed skepticism about that capability.
