![]() “We want to develop next version that utilizes as much information as possible to reduce possible false alarms and reliably detect malicious and modified devices.” ‘Cat and mouse’īräunlein told The Daily Swig that Apple could incorporate AirTag imitators into its threat model by “excluding non-genuine devices from the network” or “improving the detection logic to also detect nearby trackers”. “The main issue is that a lost iPhone or a closed MacBook send exactly the same signals as such a tracker,” he said. Heinrich said SEEMOO is now working on a follow-up project. “iOS and Tracker Detect ignore those devices since they mimic a lost iPhone,” Alexander Heinrich, SEEMOO PhD student and a security expert on the AirGuard project, told The Daily Swig.ĭespite its success against Bräunlein’s AirTag imitator, AirGuard was actually designed to detect off-the-shelf devices, such as the Chipolo One Spot and modified, speaker-free AirTags, which Heinrich said are fuelling stalking. ![]() Read more of the latest IoT security news While the clone went undetected by Apple’s asset-tracking apps for the iOS and Android ecosystems – Find My and Tracker Detect, respectively – it was spotted by a third-party alternative.ĪirGuard, which was developed by the Secure Mobile Networking Lab (SEEMOO) at the Technical University of Darmstadt’s computer science department, discovered the clone in ‘manual scan’ mode. These include a new ‘Precision Finding’ function, refinements to unwanted-tracking alert logic, and use of louder audio alerts. The clone, which had no speaker, was also undetectable by beeping alerts.īräunlein said Apple’s upcoming privacy changes would be similarly toothless in the face of modified or cloned AirTags. ![]() The most common method for detecting unwanted AirTags – iPhone notifications that are triggered when AirTags are separated from their owner’s device but observed moving with another device – was readily bypassed by programming the clone “to continuously broadcast new, never-seen-before public keys”. RECOMMENDED Jaw-dropping Coinbase security bug allowed users to steal unlimited cryptocurrency However, Fabian Bräunlein, co-founder of Berlin-based infosec consultancy Positive Security, said he quickly devised some “quite obvious bypass ideas for every current and upcoming protection measure”, before building an OpenHaystack-based AirTag clone to validate his hypotheses. ‘Obvious bypass ideas’Īpple moved to address fears around unwanted tracking earlier this month by unveiling a raft of safety warning enhancements. However, several reports of malicious misuse have surfaced, from devices planted to facilitate grand theft auto to those surreptitiously slipped into victims’ coat pockets. Launched in April 2021, AirTags communicate with Apple’s Find My service to help users keep track of personal items such as keys, wallets, and luggage. Third-party app allegedly outperforms Find My service by detecting the DIY deviceĪ security researcher claims he bypassed the tracking protection features built into Apple’s Find My app and AirTag tracking devices with a custom-made AirTag clone.Īmid mounting concerns that AirTags are ripe for abuse by stalkers and other wrongdoers, the researcher said he successfully tracked an iPhone user for five days (with their consent) without triggering a single tracking notification.
