Iranian hackers compromise Telegram’s secure messaging

Telegram prides itself on private messaging that lets activists escape government censorship and crackdowns, but it might have a crisis on its hands in Iran. Security researchers speaking to Reuters say that an Iranian hacking group has not only breached over a dozen Telegram accounts, but identified the phone numbers of over 15 million of the service’s users in the country. The intruders reportedly intercepted SMS authentication codes and used those to add devices to their accounts, letting them read messages and impersonate others.
