A computer security firm on Wednesday revealed a flaw that could let hackers break into WhatsApp or Telegram messaging accounts using the very encryption intended to protect messages.Check Point Software Technologies said that it alerted Telegram and Facebook-owned WhatsApp last week, waiting until the vulnerability was patched before making it public.

Check Point did not specify how many messaging accounts were at risk, but did say the flaw posed a danger to “hundreds of millions“ of users accessing the messaging platform from web browsers in computers, as opposed to mobile applications.“This new vulnerability put hundreds of millions of WhatsApp Web and Telegram Web users at risk of complete account take over,“ Check Point head of product vulnerability Oded Vanunu said in a release. “By simply sending an innocent looking photo, an attacker could gain control over the account, access message history , all photos that were ever shared, and send messages on behalf of the user.“

The vulnerability made it possible for an attacker to booby-trap a digital image with malicious code that could spring into action after the picture is clicked on for viewing. The code could then hijack an account, and spread itself like a virus by sending infected messages to those listed as contacts.
