The US federal agency has notified its 4 Million current and former government employees that their private data has been compromised in a massive data breach.
Hackers managed to break into US government computer systems in the Office of Personnel Management (OPM) and steal records of Millions of employees, making it one of the largest known breaches of information ever on federal workers.
The stolen information includes birth dates, credit card data, banking records, security clearance information, and background checks dating back three decades, potentially affecting people across the spectrum of the federal agency.
The massive breach is believed to be carried out by the hackers based in China, the Obama administration announced on Thursday. The breach is believed to be an “attack against the (American) nation.”
However, China has denied any involvement in what could be the largest cyber-attack in US history by calling such claims “irresponsible”.
