DRTBox — Spies in the Sky
"This cell phone spying program – which potentially affects the privacy of everyone from Orange County's 3 million residents to the 16 million people who visit Disneyland every year – shows the dangers of allowing law enforcement to secretly acquire surveillance technology," said Matt Cagle, technology and civil liberties policy attorney for ACLU-NC.
How does DRTBox Work?
"Our products are lightweight, low power, small, and are supportable on multiple platforms. Our products are featured in UAVs, planes, helicopters, vehicles, towers, and on walk-tests, submarines, and boats." DRT website claims.
As it targets all nearby cellular devices, so Law Enforcements are able to get information from hundreds of devices concurrently.
How does DRTbox Crack Carrier-based Encryption?
- lack of tower authentication,
- bad key derivation algorithms
- and terrible encryption algorithms,
...it is easily crackable.
How to Protect yourself from DRTbox or Stingrays
Don't confuse carrier-based encryption with application-level encryptions (end-to-end encryption), both are different.
So, if you are concerned about police snooping on your communication, the best option is...
...use software to encrypt your emails (PGP), instant messages (Telegram or Signal), documents and even your voice calls (RedPhone).
Besides this, you can also enable 3G/4G/LTE-only mode from device settings to forcefully limit your smartphone to use only secure connection.
This would prevent DRTBox or any cell phone tracking device to intercept your data communication, but might allow location tracking.
