🇺🇸 🇬🇧 AnyTone AT-D878UVII Plus - Vulnerability in DMR RC4 and AES encryption

Описание: If you are using the AnyTone ARC4 and AES encryption you should know that there is a vulnerability inside.

This encryption is fully compatible with Motorola Enhanced Privacy ARC4/AES but its implementation is based on predictable initialization vectors (IV).

In this video I explain you why these predictable IVs introduce a vulnerability and how a hacker can decipher your network without knowing your secret key.
