BROSIX AND CHATOX PROMISED TO KEEP YOUR CHATS SECURED. THEY DIDN'T

Summary from the TLDR InfoSec newsletter

Chatox and Brosix are both communications platforms for personal and team use owned by Stefan Chekanov. A security researcher discovered an unencrypted backup of chat logs containing 155.3GB of unique, compressed files containing over 65M stored messages and 73K files for Chatox and over 37M messages and 191K files for Brosix. Upon notification, the Brosix backup was secured, but the Chatox backup is still unsecured.
