Final Thoughts
While the £47 million loss is significant, HMRC’s rapid response ensured that taxpayers weren’t financially harmed. This case highlights how identity-based phishing – not hacking – is becoming the most common route for scammers to exploit public systems.
Stay alert. Monitor your communications. And if in doubt, always contact HMRC directly via official channels.
