==The Twitter Hack==
On July 15, 2020 around 130 high profile twitter accounts were compromised and used to promote a money doubling Bitcoin scam. The attackers had gained access to Twitter's administrative tools which allowed for the attackers to access anyone's account and to do anything on it. The attack initially targeted Twitter accounts with rare handles such as @6 and @anxious. The attackers set up a thread on the popular forum OGUsers which is a popular marketplace for rare accounts on a wide variety of different social media platforms and games (especially Minecraft). In this thread the attackers promised any handle on Twitter for the price of $250.https://krebsonsecurity.com/2020/07/three-charged-in-july-15-twitter-compromise/
