  • Crypto Scam Alert: UK Minister’s X Account Hacked to Promote Fake Token

    Crypto Scam Alert: UK Minister’s X Account Hacked to Promote Fake Token

    In a concerning development for cryptocurrency security, UK Government Minister Lucy Powell’s X (formerly Twitter) account was compromised yesterday morning by hackers promoting a fraudulent cryptocurrency dubbed ‘House of Commons Coin’ ($HCC). This incident highlights the ongoing challenges of crypto security and social media exploitation.

    Anatomy of the Social Media Crypto Scam

    These incidents typically follow the classic ‘pump and dump’ scheme structure:

    • Initial compromise of verified accounts
    • False endorsement of new cryptocurrencies
    • Artificial price inflation
    • Quick profit-taking by scammers
