Find my Hacker: how Apple's Network May be a Potential Tracking Tool > 자유게시판

George Mason University researchers lately uncovered a means for ItagPro hackers to trace the location of practically any computer or iTagPro geofencing mobile machine. Named "nRootTag" by the group, the assault makes use of a device’s Bluetooth address mixed with Apple's Find My community to essentially turn goal gadgets into unwitting homing beacons. Junming Chen, ItagPro lead author of the study. The workforce of Qiang Zeng and Lannan Luo-both affiliate professors within the Department of Computer Science-and PhD college students Chen and Xiaoyue Ma discovered the assault works by tricking Apple's Find My community into thinking the target system is a misplaced AirTag. AirTag sends Bluetooth messages to nearby Apple devices, which then anonymously relay its location via Apple Cloud to the owner for monitoring. Their assault method can turn a device-whether it is a desktop, smartphone, or portable tracking tag IoT machine-into an "AirTag" with out Apple's permission, iTagPro device at which point the community begins monitoring. In experiments, they had been able to pinpoint a stationary pc's location to inside 10 toes, ItagPro accurately monitor iTagPro portable a shifting e-bike's route through a metropolis, ItagPro and ItagPro even reconstruct the exact flight path and determine the flight number of a gaming console brought onboard an airplane.

Zeng gave an alarming instance: "While it's scary in case your smart lock is hacked, it becomes far more horrifying if the attacker also knows its location. While Apple designs an AirTag to change its Bluetooth deal with based on a cryptographic key, an actor couldn't do this on different techniques with out administrator privileges. So instead of attempting to modify the Bluetooth tackle, the researchers developed efficient key search methods to discover a key that's compatible with the Bluetooth address, making the key adapt to the address instead. What makes nRootTag significantly unsettling is a ninety p.c success fee and the power to track units inside minutes. The method doesn't require sophisticated administrator privilege escalation sometimes needed for such deep system entry. Instead, it cleverly manipulates the Find My Network's belief in system indicators, essentially turning Apple's useful lost-system characteristic into an unwitting accomplice. The researchers demonstrated that the attack works broadly on computer systems and cell units running Linux, Android, and Windows, as well as a number of Smart TVs and VR Headsets.

Chen. They used a whole lot of graphics processing models (GPUs) to help discover a match rapidly, benefiting from the affordability in the current GPU rental landscape, the place individuals rent out idle GPUs for credits, pushed by earlier mining developments and the present AI boom. Chen defined that unlike Bitcoin mining the place just one answer is kept, their mismatches will be saved to a database (referred to as a rainbow desk) for future use, making it particularly effective for concentrating on 1000's of devices concurrently. Chen suggested this technique might be enticing to advertising corporations trying to profile customers with out relying on machine GPS. Most concerning are the privateness implications, as unhealthy actors may simply abuse this technique for stalking, harassment, corporate espionage, or threats to nationwide security. The researchers beneficial to Apple that it replace its Find My network to higher confirm devices, but a true repair might take years to roll out. The crew knowledgeable Apple of the problem in July of 2024 and Apple formally acknowledged it in subsequent security updates, although they have not disclosed how they will patch the problem.

The results obtained in laboratory exams, utilizing scintillator bars learn by silicon photomultipliers are reported. The current approach is step one for designing a precision tracking system to be positioned inside a free magnetized volume for the cost identification of low vitality crossing particles. The devised system is demonstrated ready to offer a spatial decision higher than 2 mm. Scintillators, Photon Solid State detector, particle monitoring units. Among the deliberate actions was the construction of a gentle spectrometer seated in a 20-30 m3 magnetized air volume, the Air Core Magnet (ACM). The whole design should be optimised for the willpower of the momentum and charge of muons in the 0.5 - 5 GeV/c range (the mis-identification is required to be lower than 3% at 0.5 GeV/c). 1.5 mm is required inside the magnetized air volume. In this paper we report the results obtained with a small array of triangular scintillator bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.
