In a concerning turn of events, healthcare technology company Change Healthcare is now facing another ransomware threat from a different group, adding to the already chaotic cyber attack it endured earlier this year. The group, known as RansomHub, claims to have obtained stolen data from Change Healthcare and is demanding an unspecified ransom for its return.

The ransomware situation for Change Healthcare initially emerged in March when AlphV, a ransomware group, took credit for encrypting the company's network and threatened to expose sensitive healthcare data unless a ransom was paid. Reports reveal that AlphV potentially received a $22 million payment, although Change Healthcare has not confirmed this transaction.

Now, RansomHub, a relatively new ransomware group, has announced on their dark-web site that they possess 4 terabytes of data stolen from Change Healthcare. They have threatened to sell this information to the highest bidder unless the company complies with their ransom demands.

Although RansomHub did not provide any sample data initially, they recently sent several screenshots of patient records and a data-sharing contract involving United Healthcare and Emdeon, the parent company and previous owner of Change Healthcare, respectively. These screenshots, while not fully confirmed, suggest that RansomHub's threat may hold more weight than previously believed.

Change Healthcare has yet to respond to RansomHub's extortion demand, and their silence has perturbed experts and analysts in the field. Brett Callow, a ransomware analyst from Emsisoft, states that it is unclear whether RansomHub's data is authentic, but there is no evidence to suggest it is not genuine. Jon DiMaggio, chief security strategist at Analyst1, reviewed the information provided by RansomHub and believes that they have indeed acquired Change Healthcare's data.

If RansomHub's claims prove to be true, this development highlights the danger of trusting ransomware groups to uphold their end of the bargain, even after payment is made. Change Healthcare's previous payment to AlphV did not result in the expected outcome, with reports suggesting that the group vanished without sharing any commission with their affiliates.

This new ransomware threat further adds to the ongoing disruption caused by the attack on Change Healthcare, leaving numerous pharmacies and medical practices across the United States unable to process claims. The extent of the impact and potential compromises to sensitive patient data remains a matter of concern.

As the situation unfolds, industry experts underscore the critical need for heightened cybersecurity measures and vigilance in countering ransomware attacks. The healthcare sector, in particular, must remain vigilant to protect the integrity of patient information and ensure operational resilience in the face of evolving cyber threats.

Change Healthcare's response to the latest ransomware demand from RansomHub remains eagerly awaited, as stakeholders anxiously hope for a swift resolution to this challenging and high-stakes situation.
