> The other tech giant that can be compelled by law enforcement to hand over potentially large amounts of sensitive messaging data is Apple. iMessage, Apple’s text-message service, comes loaded on the iPhone and is used by 1.3 billion people worldwide. According to the FBI’s “Lawful Access” guide, if served with a court order or a search warrant, Apple must hand over basic subscriber information as well as 25 days’ worth of data about queries made in iMessage, such as what a targeted user looked up in iMessage and also which other people searched for that targeted user in the app. That doesn’t include actual message content or whether messages were exchanged between different users. > But the amount of data available to law enforcement is potentially far greater — greater even than the user data provided by WhatsApp — if a targeted user backs up their iMessage activity to iCloud, Apple’s online storage platform. If that’s the case, the FBI document says, then law enforcement can request back-ups of the target’s device, including actual messages sent and received in iMessage if they’re backed up in the cloud. > While Apple describes iCloud as an encrypted service, it comes with a giant loophole. Apple holds an encryption key that can unlock user data in iCloud, and so police departments or federal agencies can request that key with a search warrant or a customer’s consent to access certain user data. “You’re handing someone else the key to hold onto on your behalf,” says Mallory Knodel of the Center for Democracy and Technology. “Apple has encrypted iCloud but they still have the keys, and as long as they have the key, the FBI can ask for it.”
