The Clop ransomware group has stolen stole personal and health information of 489,830 individuals as a result of a ransomware attack on the technology firm Intellihartx. The attack took place earlier this year, the attackers have exploited the GoAnywhere zero-day vulnerability tracked as CVE-2023-0669.
In February, the Clop ransomware group claimed to have stolen sensitive data from over 130 organizations by exploiting a zero-day vulnerability (CVE-2023-0669) in Fortra’s GoAnywhere MFT secure file transfer tool.
“On February 2, 2023, ITx discovered that its secure file transfer protocol provider, Fortra, was subject to a
data privacy event that potentially impacted ITx’s clients’ patient information (“Fortra Event”). ITx promptly launched an investigation to determine the nature and scope of the Fortra Event. On March 24, 2023, ITx completed its initial review of the logs provided to it by Fortra. ITx began notifying potentially affected data owners on April 11, 2023.” reads the data breach notification issued by the company. “ITx completed a further review of the additional logs provided by Fortra, as well as correspondence with the unauthorized party, to determine the scope of impacted information on May 10, 2023.”
Compromised data may include name, address, medical billing and insurance information, certain medical information such as diagnoses and medication, and demographic information such as date of birth and Social Security number.
Intellihartx is not aware of any misuse of the stolen information.
The company notified law enforcement regarding the security breach and is offering free credit monitoring services for one year, through Experian, to the impacted individuals. TITx also provided impacted individuals with guidance on how to prevent identity theft and fraud.
Intellihartx is the latest company to be the victim of the massive hacking campaign that exploited zero-day in Fortra’s GoAnywhere file-transfer software. Other victims of the Clop ransomware are City of Toronto, Rubrik, Onex, Axis, Bank, Rio Tinto, Hitachi Energy, and Virgin Group.
Other organizations have observed exploitation attempts but said the attack had limited impact.
The Cl0p cybergang has also claimed responsibility for the recent MOVEit Transfer MFT zero-day attack, which impacted several major organizations, including Irish airline Aer Lingus, British Airways, the BBC, UK-based payroll and HR company Zellis, and the Canadian province of Nova Scotia.
