The Intercept:

Apple promises that your iMessage conversations are safe and out of reach from anyone other than you and your friends. But according to a document obtained by The Intercept, your blue-bubbled texts do leave behind a log of which phone numbers you are poised to contact and shares this (and other potentially sensitive metadata) with law enforcement when compelled by court order.

An Apple spokesperson confirmed only that the logging information in the iMessage FAQ is “generally accurate,” but declined to elaborate on the record.

This might be minor or it might be significant, depending on how the information is being used. Regardless, it’s a peek behind the security curtain that tells us we may not be as secure or “hidden” from prying eyes as we would think or hope.
