IMESSAGE SECURITY IS A MYTH

Apple’s iMessage instant messenger service, which has
made headlines for being uncrackable by law enforcement, is not so secure after all, according to Quarkslab. An internal document from the United States Drug Enforcement Administration published in April stated that it was impossible to intercept iMessages between two Apple devices. “As Apple claims, there is end-to-end encryption,” Quarkslab researcher Cyril Cattiaux said. “The weakness is in the key infrastructure as it is
controlled by Apple.”
