GPS ankle monitor hacking: How I got stalked by people from the Arab Emirates
Ankle monitors are devices typically used by law enforcement to track offenders, have you ever wondered how they work - which potential vulnerabilities they have or where to buy one ( or many )? This talk is about hacking electronic ankle monitors built by various Chinese manufacturers - and the protocols and software they use.
Ankle monitors are devices used by law enforcement to track offenders - typically ones on house arrest. They contain various sensors and GPS, WiFi, Cellular and sometimes RF communication to transmit data and determine their position.
This talk will go into detail for various brands on how they communicate with their servers - potential vulnerabilities and ways to escape/avoid detection. This talk concerns Chinese vendors of ankle monitors - but the processes are applicable to different brands and types as well. I will discuss how I developed a server which can be used with 4 vendors of these devices - and how I got the protocol documents for each of them through a bit of social engineering.
The focus will be on the technical details of how your location is determined - which fallbacks are used in case locating falls - and how data is communicated to the server - and the security implications of all of this. Some of devices are used by small nations to track for instance immigrants for COVID tracking - we will discuss the implications of this.

This is a submission for a keynote talk at MCH2022. The Internet is both a familiar, comfortable place as well as a bottomless rabbit hole you can lose yourself in. The Internet has always been like this from its inception, the difference now is the scale and consequences are almost immeasurable - and it tests the limits of human imagination. When you look into the mirror of the Internet what you see reflected back depends on what you are looking for. It has become largely a reflection of ...

Have you ever forgotten a passphrase or lost a hardware token? Lost access to enough Bitcoin to buy a pizza or two? Encryption is fundamental to securing our liberties, but key and password management remain difficult even for professionals, let alone the general public. This talk presents Passcrow, an Open Source project attempting to address one of crypto's largest usability issues: password and key recovery in a decentralized environment.

Thanks to DNSSEC and DANE, it is possible to automatically verify user@domain.name identities by checking with domain.name servers. The real problem however, is integration with existing protocols, instead of inventing something completely new and perhaps web-only. The purpose of our work on Realm Crossover mechanisms has been to design generic solutions that extend many different application protocols, without changing their protocol specs.
