A new hacking group known as “Kairos” has emerged, allegedly breaching multiple organizations, mainly in the healthcare and accounting sectors.
The group has recently published its victims on an Onion blog, exposing sensitive data from six different organizations.
This development has raised significant cybersecurity concerns, particularly in sectors that handle personal and medical information.
Targets in Healthcare and Accounting
According to a post shared by cyber analyst @HackManac, Kairos has listed six primary targets on its blog.
These organizations are spread across Taiwan and the United States and include both healthcare and accounting firms.
The list of victims includes:
- 🇹🇼 Taiwan: Formosa Certified Public Accountant
- 🇺🇸 USA: PMR Centre
- 🇺🇸 USA: Accounting & Advisory Services
- 🇺🇸 USA: Clay Platte Family Medicine Clinic
- 🇺🇸 USA: Kansas Regenerative Medicine
- 🇺🇸 USA: Sunny Days Sunshine Center
Kairos has provided samples of the stolen data, which reportedly includes personally identifiable information (PII), medical records, employee data, and other sensitive documents.
This type of data exposure places both the organizations and their clients at risk of identity theft, fraud, and further cyberattacks.
Previous Breaches Linked to MEOW Group
Interestingly, some of Kairos’ victims have been targeted by other hacking groups in the past.
The PMR Centre, for instance, was previously listed by the MEOW cybercriminal group in July 2024.
Similarly, Clay Platte Family Medicine Clinic suffered a data breach in June 2024, where compromised data included protected health information (PHI).
This raises questions about whether these organizations have taken adequate steps to secure their systems following earlier breaches.
Kairos’ onion blog shares many similarities with the template used by the notorious Cactus ransomware group.
The format and structure of the site suggest that Kairos may be adopting tactics from other established hacking groups to gain notoriety.
