I think Twitter got hacked. Theres so many more people that posted this. Apple, Bezos, Elon, Biden, Coinbase... the list goes on. The scary thing is, this could have been used to do massive damage.
They tried to do massive damage with these accounts but failed to do so because people are more aware nowadays so only a minor amount of people did actually sent their bitcoins to that wallet hoping they would be getting double money in return, but actually we all knew that it was a scam right from the start.
And twitter already recognizes their mistake and made a post about it. The vector of the attack was some twitter employers, they got hacked by social engineering and after that all the accounts was vulnerable.
Will be hard to see an attack like this again. For sure they will do something about the security to avoid it.
As the attack was a social engineering attack so we can see this type of attack again in the future, employees are people only who can easily be fooled by social engineering attacks and falls in the trap of hacker, no matter how much secure your firewall is, if someone inside it opens a door to attacker then he can do a lot of damage once he is inside the system. Although most employees also get this type of training in tech firms to recognise a social engineering attack and also to tackle it.
