February’s crippling ransomware assault towards Change Healthcare, which noticed prescription orders delayed throughout the US, continues to have critical penalties.

The cybercriminal group RansomHub revealed a portion of what it claims to be the numerous hundreds of thousands of affected person data it stole within the assault on the darkish internet, together with medical data, insurance coverage data, and billing particulars.

RansomHub claims 4TB of stolen knowledge are up on the market to the very best bidder until Change Healthcare pays a ransom.  The haul is claimed to additionally comprise contracts and authorized agreements between Change Healthcare and its enterprise companions.

What makes the scenario somewhat extra advanced is that RansomHub will not be the primary cybercriminal group to assert duty for the extremely disruptive Change Healthcare hack.

The ransomware assault was initially attributed to the BlackCat ransomware gang (also called ALPHV). Certainly, it was reported that BlackCat/ALPHV had acquired a cryptocurrency cost equal to US $22 million in early March in what was extensively assumed to be a ransom cost.

If that is correct, why would a distinct cybercrime gang now seem like demanding a ransom cost from Change Healthcare? Is that this a separate knowledge breach, or two completely different teams trying to extort cash for a similar theft?

What is feasible is that the safety breach is being linked to 2 completely different teams as a result of associates and members of a ransomware gang have fallen out with one another and squabbled about how greatest to divide the proceeds.

For its half, RansomHub told Wired that it was not affiliated with the BlackCat/ALPHV group and declined to reveal the ransom quantity demanded from Change Healthcare.

Regardless of the actuality is of who stole what, and the way a lot ransom they could have demanded, the sale of the exfiltrated knowledge raises the stakes dramatically for each sufferers and the business as a complete.

Sufferers now discover themselves at elevated threat of identification theft and monetary fraud, in addition to probably discrimination primarily based upon their leaked medical data.  In the meantime, insurers concern they could see a major surge in fraudulent claims which – in flip – may drive up prices for shoppers.

None of which is nice information, and raises an fascinating query – how will Change Healthcare reply to the most recent ransom demand?

Change Healthcare’s father or mother firm, UnitedHealth Group, says that it continues to “make progress in mitigating the influence” of February’s cyber assault.
