Vladimir Putin’s forces launched their full-scale invasion of Ukraine—a handful of Russian opposition politicians gathered in front of Saint Petersburg’s palatial Law, Order, and Security building.
They had come to officially request permission to hold a rally opposing the war, which they knew would be denied. In April, after having made it safely to Armenia, Matsapulina recounted the episode in a Twitter thread. She ruled out the chance that anyone in her close-knit group had been cooperating with security forces (they’d all also left Russia by then), which left two conceivable explanations for how the officers had read her private Telegram messages.

Over the past year, numerous dissidents across Russia have found their Telegram accounts seemingly monitored or compromised.
