In January 2025, Le Monde reported that the crews of a number of French Navy nuclear-powered submarines logged their movements on the app while their boats were underway. The outlet said it therefore became possible to know of each submarine’s location and other information such as patrol patterns and schedules despite the fact that such information should have remained confidential.
The earlier report also found that many of the crews had used their real names and had publicly visible profiles on the app, thus raising concerns about possible breaches of national security.
Le Monde had earlier quoted French Navy officials as saying that the leaks were the result of “negligence on the part of the personnel” but that there was no “major risk.”
