The infamous Twitter-bitcoin scam filled $100k worth of cryptocurrency into scammers pockets. 130 accounts including those of Elon Musk and former US president Barack Obama were used to carry out this attack. Twitter, in its blog post, said that hackers used ‘spear-phishing’ technique to trap employees into leaking confidential information. Until last week, approx. 1500 of Twitter’s employees had access to its control settings. This has now been restricted.
