The Cybersecurity and Infrastructure Security Agency (CISA) and the Food and Drug Administration (FDA) have issued warnings regarding a critical security flaw in Contec CMS8000 patient monitors. These monitors, manufactured by a Chinese company, contain a hidden backdoor that allows for unauthorized remote access. This backdoor enables the devices to connect to a hard-coded IP address located at a third-party university in China, potentially allowing the download and execution of unverified files. The vulnerability, tracked as CVE-2025-0626 and CVE-2025-0683, impacts all analyzed firmware versions of the device.
The discovered backdoor poses a significant risk to patient safety and data privacy. It allows malicious actors to modify device settings, execute arbitrary code, and alter displayed vital signs. Furthermore, patient data, including personal and health information, is being sent in plain text to the hardcoded IP address. This unauthorized exfiltration of sensitive information and the potential for device manipulation could lead to improper medical responses and endanger patient well-being. CISA has stated that the backdoor is unlikely to be a normal update mechanism, noting it lacks any integrity-checking or version tracking, making it difficult for hospitals to detect compromised devices.

- : Claroty : There was increased interest in healthcare industry's patient monitors after CISA warned on 31 January 2025 that . Claroty's Team82 actually previously investigated the firmware and reached the conclusion that it is most likely not a hidden backdoor, but instead an insecure/vulnerable design that introduces great risk to the patient monitor users and hospital networks. Their conclusion is mainly based on the fact that the vendor—and resellers who re-label and sell the monitor—list the IP address in their manuals and instruct users to configure the Central Management System (CMS) with this IP address within their internal networks. h/t: ; cc: Note: there's associated vulnerabilities: (CVSSv4: 7.7/v3.1: 7.5 high) Hidden Functionality vulnerability in Contec Health CMS8000 Patient Monitor (CVSSv4: 8.2 high/v3.1: 5.9 medium) Exposure of Private Personal Information to an Unauthorized Actor vulnerability in Contec Health CMS8000 Patient Monitor

The New York Blood Center Enterprises (NYBC), a major provider of blood and blood products, has been targeted by a ransomware attack, severely impacting its IT systems. The incident, which was detected on Sunday, January 26th, forced NYBC to take systems offline as a precautionary measure to contain the threat. Cybersecurity experts were immediately engaged and an investigation was launched in conjunction with law enforcement. While the organization is working to restore services, it has noted that operations will be affected and that it is deploying workaround solutions to minimize the disruption. The attack has raised concerns about potential impacts on critical blood donation and distribution services across the region.
NYBC has emphasized that it remains focused on the health of the communities it serves and is taking all possible steps to restore its IT infrastructure. The organization is working with hospital partners to maintain services, while also expressing gratitude for support from the healthcare community during this time. There is currently no indication whether or not sensitive patient or donor data has been compromised, nor has any information on ransom demands been provided. The attack underscores the increasing vulnerability of healthcare entities to cyberattacks and the potential risks associated with these kinds of malicious activities.

BlackBasta ransomware group's attack on Ascension Health, one of the largest healthcare providers in the US, has been brought to light by leaked chat logs. The incident, which occurred in May 2024, significantly disrupted services and involved the exfiltration of 1.4TB of data and encryption of over 12,000 servers. The BlackBasta gang gained initial access months prior to deploying the ransomware, starting around November 2023, using phishing and password guessing techniques to compromise 14 email addresses of Ascension Health employees.
These leaked chat logs provide researchers a unique opportunity to understand the inner workings of the Russia-based cybercrime enterprise. The BlackBasta gang, consisting of former Conti ransomware members, exhibits similar operational structures. Veriti Research analyzed the leaked communications, revealing that BlackBasta exploited vulnerabilities in VMware ESXi, Microsoft Exchange, Citrix VPNs, and Fortinet firewalls, and Active Directory. The gang also uses cloud services for malware hosting and adjusts tactics to evade detection, while expressing frustration when EDRs, firewalls, and IP reputation monitoring disrupt their operations.

The FDA and CISA have issued warnings regarding cybersecurity vulnerabilities found in Contec CMS8000 and Epsimed MN-120 patient monitors. These monitors, often used for remote patient care in homes and hospice settings, present potential risks when connected to the internet. The agencies advise users to disconnect these devices from the network where possible.
These vulnerabilities could allow unauthorized access and manipulation of the devices. CISA discovered a backdoor function with a hard-coded IP address in all analyzed firmware versions of the Contec CMS8000. The identified risks include the potential for unauthorized transmission of patient data and remote code execution, with one vulnerability scoring a critical 9.8 CVSS. These patient monitors display vital patient information including temperature, heartbeat and blood pressure.
