That means leaked. Like in secrets.

Russia publishes German army meeting on Ukraine – Germany is investigating the apparent interception by Russia of army officers discussing supplying Ukraine with long-range missiles – and possible targets.
Audio of the video-conference meeting was posted to social media by the head of Russia’s state-run RT channel.
The officers discuss how the missiles could hit the Kerch Bridge, which links Russia to the illegally annexed Crimea.
Russian politicians said the audio proved that its “sworn enemy” was planning attacks.
