Thirteen Romanians have been arrested for their involvement in a phishing scheme targeting His Majesty's Revenue and Customs (HMRC), resulting in significant financial losses for the UK government. The operation, conducted by Romanian police in collaboration with HMRC, revealed that organized crime groups exploited stolen data to submit fraudulent tax claims and benefits. HMRC confirmed that the attacks led to a loss of £47 million for taxpayers, although there was no direct cyber attack on its systems.
