Apple logs your iMessage contacts and could share them with police
Apple's iMessage had a few security holes in March and April that potentially leaked photos and contacts, respectively. Though quickly patched, they are a reminder that the company faces a never-ending arms race to shore up its security to keep malicious hackers and government agencies out. But that doesn't mean they will always be able to keep it private. A report from The Intercept states that iMessage conversation metadata gets logged in Apple's servers, which the company could be compelled to turn over to law enforcement by court order. While the content of those messages remains encrypted and out of the police's hands, these records list time, date, frequency of contact and limited location information.
When an iOS user types in a phone number to begin a text conversation, their device pings servers to determine whether the new contact uses iMessage. If not, texts are sent over SMS and appear in green bubbles, while Apple's proprietary data messages appear in blue ones. Allegedly, they log all of these unseen network requests.
