The attack is believed to have been carried out by threat actors motivated by personal gain, although the exact nature and extent of their goals are not yet clear.

The incident is reported to have involved an internal denial of service, where the attackers used tactics, techniques, and procedures (TTPs) to disrupt the hospital's internal systems and networks. This type of attack can have severe consequences, including the loss of access to critical systems and data, and can compromise the availability of essential services.
The hospital's ability to provide patient care was likely impacted by the attack, with potential delays or disruptions to medical procedures, treatments, and other essential services. The incident highlights the critical importance of robust cybersecurity measures in the healthcare sector, where the consequences of a successful attack can be severe and far-reaching.
The attackers' use of internal denial of service tactics suggests a high degree of sophistication and planning, and may indicate that the attackers had prior knowledge of the hospital's internal systems and networks. The fact that the attack was carried out from within the hospital's network also raises concerns about the potential for insider involvement or compromised credentials.
The hospital's response to the incident is not yet clear, although it is likely that they will be working to restore systems and services as quickly as possible. The incident may also prompt a wider review of the hospital's cybersecurity measures, including their incident response plans and procedures.
