Telegram crammed: Hackers find way to send massive messages

Researchers have found what they say is a flaw in the Telegram that allows messages of any size to be sent.

The unpatched flaw demonstrated in a proof-of-concept shows how attackers can send mesages of any size over the popular encrypted communications app by skirting restrictions.

Telegram has been contacted for comment. Iranian researcher Sad Ghaf did not pinpoint the flaw in a bid to prevent others exploiting it, and says he could not find a way to report the flaw to Telegram.
