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. To get the phone numbers, they took advantage of a Telegram programming interface.
It's not certain that the Iranian government is behind the attacks. However, the culprits (Rocket Kitten) have launched phishing campaigns that reflect official "interests and activities," according to the researchers. Also, the compromised targets included members of both opposition and reform groups -- and it's safe to say that some of those 15 million phone numbers could expose other activists and journalists.
