What happens when a healthcare giant falls victim to one of the most devastating cyberattacks in history? UnitedHealth Group has now revealed that the February 2024 ransomware attack on Change Healthcare compromised a staggering 190 million individuals—nearly twice the original estimate. Despite the unprecedented scale, millions affected have yet to receive formal notifications, even as their data circulates in the hands of cybercriminals.
A $22 million ransom was paid to stop the data from leaking, but in a stunning betrayal, the hackers pocketed the money and never delivered on their promise. Meanwhile, a new ransomware group emerged, seeking even more ransom. Was this a calculated double-cross?
