Hackers were able to hijack dozens of high-profile Twitter accounts on Wednesday after gaining access to internal user administration tools and systems.
The accounts were later used to promote a cryptocurrency scam that allowed the attackers to collect over $100,000 from gullible victims who were promised to receive free bitcoins in exchange for a proof transfer or to get their bitcoins doubled.
