We saw another ransomware operation shut down this week after first getting breached by law enforcement and then targeting critical infrastructure, putting them further in the spotlight of the US government.
What makes this strange is that this seems to be a common routine for the DarkSide, I mean BlackCat/ALPHV, ransomware operation which tends to hit critical infrastructure, and then realize it was a big mistake.
As it was, they were already being targeted by an international law enforcement operation, allowing the FBI to hack the gang's servers for months while collecting data, decryptors, and ultimately, seizing the domain of the data leak site.
While the Tor onion domain seizure was a game of tug of war between the FBI and BlackCat, instead of shutting down, the ransomware gang decided to continue operating and vowed to target US critical infrastructure in revenge.
Approximately two months later, one of their affiliates attacked UnitedHealth Group's Change Healthcare, a technology solutions company used by many pharmacies, doctor's offices, and hospitals for billing claims for healthcare and prescriptions.
This attack led to severe disruption in the US healthcare system, preventing pharmacies from accepting insurance and discount cards and, in some cases, causing patients to pay full price for medicine.
Similar to their attack on Colonial Pipeline as DarkSide, which led to them to shut down, their rebrand as BlackCat/ALPHV has now shut down after the Change Healthcare attack.
According to an affiliate, Optum, Change Healthcare's parent company and a subsidiary of UnitedHealth, paid a $22 million ransom to the ransomware operation to prevent the leaking of stolen data and to receive a file decryptor.
However, this affiliate says that BlackCat stole the ransom and did not transfer over a share of the payment, stating it was seized by the "feds."
In reality, BlackCat performed an exit scam where they stole the ransom, blamed law enforcement, and shut down, stating that they do not want to be in court again.
Unfortunately, it is only a matter of time before we see the ransomware operation rebrand under a new name to repeat this cycle.
In other news, the Stormous ransomware gang attacked the Duvel Belgian beer maker, which many consider critical infrastructure.
Finally, the Swiss government also warned that 65,000 of its documents were leaked as part of a Play ransomware attack on Xplain.
