Change Healthcare recently reported "Cyberattacks on Critical Infrastructure Disproportionately Impact Women, Yet Policy Remains Gender-Blind", a noteworthy cybersecurity incident.

Cyberattacks on essential services such as healthcare, education, and transportation are increasing in frequency and severity, with gendered impacts disproportionately burdening women due to their structural roles in both the formal workforce and unpaid care labor.

The disruption is felt across the environment, affecting healthcare, education and transportation.

Formal response steps have not been shared publicly yet.

The case underscores how teams are taking away lessons such as Cyberattacks disproportionately impact women due to their structural roles in the workforce and unpaid care labor. Gender-blind cybersecurity policy undermines resilience and risk assessment. Gender-disaggregated data is needed to improve risk assessment and resilience planning, and recommending next steps like Center real users in threat modeling, accounting for gendered engagement with technology, Measure gender-disaggregated impacts to improve risk assessment and resilience planning and Adopt human-centered security policies reflecting actual user behavior.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
