The messaging app Telegram has said it will hand over users’ IP addresses and phone numbers to authorities who have search warrants or other valid legal requests.
The change to its terms of service and privacy policy “should discourage criminals”, CEO Pavel Durov said in a Telegram post on Monday.
“While 99.999% of Telegram users have nothing to do with crime, the 0.001% involved in illicit activities create a bad image for the entire platform, putting the interests of our almost billion users at risk,” he continued.
The announcement marks a significant reversal for Mr Durov, the platform’s Russian-born co-founder who was detained by French authorities last month at an airport just north of Paris.
“Telegram’s marketing as a platform that would resist government demands attracted people that wanted to feel safe sharing their political views in places like Russia, Belarus, and the Middle East,” Mr Scott-Railton said.
“Many are now scrutinizing Telegram’s announcement with a basic question in mind: does this mean the platform will start cooperating with authorities in repressive regimes?”
Telegram has not given much clarity on how the company will handle the demands from leaders of such regimes in the future, he added.
Cybersecurity experts say that while Telegram has removed some groups in the past, it has a far weaker system of moderating extremist and illegal content than competing social media companies and messenger apps.
Before the recent policy expansion, Telegram would only supply information on terror suspects, according to 404 Media.
