  • Change Healthcare on Thursday confirmed that the ransomware group Blackcat is behind the ongoing cybersecurity attack that’s been impacting its systems since last week.
  • The attack has caused widespread disruptions to pharmacies and health systems across the U.S.
  • “We are actively working to understand the impact to members, patients and customers,” said Change Healthcare, which is owned by UnitedHealth.

Change Healthcare on Thursday confirmed that ransomware group Blackcat is behind the ongoing cybersecurity attack that’s caused widespread disruptions to pharmacies and health systems across the U.S.

“Our experts are working to address the matter and we are working closely with law enforcement and leading third-party consultants,” Change Healthcare told CNBC in a statement Thursday. “We are actively working to understand the impact to members, patients and customers.”

The company said it’s working with Mandiant, which is owned by Google, and cybersecurity software vendor Palo Alto Networks.

In a since-deleted post on the dark web, Blackcat said Wednesday that it was behind the attack on Change Healthcare’s systems. The group said it managed to extract six terabytes of data, including information like medical records, insurance records and payment information.

Change’s parent company UnitedHealth Group said it discovered that a cyber threat actor breached part of the unit’s information technology network on Feb. 21, according to a filing with the SEC. UnitedHealth isolated and disconnected the impacted systems “immediately upon detection” of the threat, the filing said, but it didn’t disclose the nature of the attack or exactly when it took place.

Blackcat, also called Noberus and ALPHV, steals sensitive data from institutions and threatens to publish it unless a ransom is paid, according to a December release from the U.S. Department of Justice. Blackcat has compromised computer networks across the U.S. and the globe, amounting to hundreds of millions of dollars in losses, the release said. 

Change Healthcare offers tools for payment and revenue cycle management that help facilitate transactions like reimbursement payments. In 2022, it merged with the…

Shares of Motilal Oswal Financial Services fall over two percent in early trade on February 19 after the domestic broking firm was targeted in a cyber-attack by ransomware group LockBit, according to TechCrunch.

The ransomware group added Motilal Oswal to its dark web leak site on Tuesday, in an attempt to blackmail the brokerage for ransom payments. On failure to meet their demands, LockBit threatened to make all the stolen data public.

At 9.17 am, shares of the brokerage were quoting Rs 1,800 apiece on the NSE, down 2.1 percent.

The domestic brokerage has around six million clients, with total assets under management of around $53 billion.

A spokesperson for the company did not respond to Moneycontrol queries.

India’s Computer Emergency Response Team was in the process of taking all appropriate action, according to the TechCrunch report.

Last year, LockBit launched cyber attacks on Granules India and public sector enterprise National Aerospace Laboratories. The gang is one of the most prolific ransomware gangs of all time, who have previously attacked IT major Accenture, UK’s Royal Mail, Boeing, and the Industrial & Commercial Bank of China.

“This had a major effect on the operations of our business due to significant changes in our IT systems and the time needed for meeting the regulatory expectations, qualifications, recertifications, and fine-tuning of quality and production systems,” the company said.
