Electronic Monitoring Spoofing Experiment

One of the core technologies used in Electronic Offender Monitoring systems is GPS. While GPS
is an indispensable tool for offender tracking, it can be circumvented. By launching a GPS
spoofing hack, an individual can fake the GPS signal and manipulate the Electronic Monitor,
effectively tricking the system into displaying a false location without triggering alerts. The Instructions on how to use GPS spoofing are freely available online, making this an increasingly
dangerous vulnerability. Offenders wearing an Electronic Monitor can trick their device into
displaying that the person is at home, while actually, they could be going anywhere, completely

The Regulus Red Team has shown with a simple test that Electronic Monitoring systems are
susceptible to GPS spoofing attacks, allowing the offender to fake his location. To protect systems
from these kinds of hacks, Regulus is providing software technology that acts as an antivirus to
detect and protect against spoofing attacks.

Easy GPS spoofing under $100

The method with which offenders are hacking their own ankle monitors involve free online software and a common device that can be easily purchased online at any e-commerce website. 

This type of signal manipulation is stealthy and enables the perpetrator to leave their permitted area, completely undetected.
