At the receiving end, CoverDrop’s secure servers remove an initial layer of encryption to filter out real messages from the cover messages. These are then provided to journalists via a dead drop delivery system, which pads the still-encrypted real messages with some cover messages to ensure the drops are always the same size. In the event a dead drop contains a message for a given journalist, they can decrypt it since it was encrypted with their public key in the first place. Since the messages also include the source’s public key, replies can be sent in the reverse fashion in a similarly secure way.
If you’re an iPhone owner, Apple’s second-gen AirTag offers a level of precision that rival trackers simply cannot match. The updated model leverages the company’s latest ultra wideband (UWB) chip for its nifty Precision Finding feature, which, in turn, can lead you to your lost item with an on-screen arrow in the Find My app. Plus, because AirTags can tap into Apple’s vast Find My network, a lost tracker can anonymously ping its location to Apple’s iCloud servers whenever it’s near another Apple device, extending its range beyond Bluetooth’s limitations.
