The US federal cybersecurity agency CISA has revealed that it did not have a prepared response plan in place for handling a recent cybersecurity incident. The incident occurred in May when an investigative reporter notified the agency about a contractor who had publicly exposed sensitive keys and credentials for accessing US government systems.
According to a postmortem report released by CISA, its staff had to spend time building an incident playbook during the early stages of the incident. This is despite the agency’s emphasis on preparing playbooks for all anticipated needs to ensure that organizations are ready to respond in the event of a security incident.
The incident was brought to light by independent cybersecurity journalist Brian Krebs, who reported that a security researcher with cyber firm GitGuardian had alerted him to reams of exposed passwords stored in a publicly accessible GitHub repository. The researcher tried to alert the contractor but didn’t hear back until Krebs contacted CISA.
CISA’s channels for allowing security researchers to notify the agency of potential incidents were not well defined, and changes have been made to make it easier and faster for researchers to contact the agency. No customer or mission data was exposed in the incident, and CISA thanked the researcher and reporter for their help.
The lack of a prepared response plan has raised concerns about the agency’s ability to respond effectively to cybersecurity incidents. The agency has been without a permanent director since January 2025 and has faced cuts, furloughs, and layoffs affecting about a third of its workforce during that time.
CISA’s incident response plan was built during the incident, highlighting the need for organizations to have prepared playbooks in place before an incident occurs. This ensures that responses are swift and effective, minimizing the impact on customers and mission data.
The agency’s admission comes at a critical time as cybersecurity threats continue to rise. CISA is responsible for protecting US government systems from cyber attacks, but its own response plan was lacking during this recent incident. The incident serves as a reminder that even well-prepared agencies can fall short in the face of an unexpected attack.
The postmortem report highlights several key takeaways for cybersecurity agencies:
* **Lack of preparedness**: CISA’s lack of a prepared response plan is a stark reminder of the importance of having incident playbooks in place before an incident occurs.
* **Communication breakdowns**: The agency’s channels for allowing security researchers to notify them of potential incidents were not well defined, leading to delays and inefficiencies.
* **Workforce challenges**: CISA has faced significant workforce challenges, including cuts, furloughs, and layoffs affecting about a third of its workforce since January 2025. This has likely impacted the agency’s ability to respond effectively to cybersecurity incidents.
The incident response plan built during this recent incident is a temporary solution that highlights the need for more robust playbooks in place before an incident occurs. CISA must take steps to address these challenges and ensure that its workforce is equipped to handle the ever-evolving threat landscape.
CISA’s incident response plan was built during the incident, but it’s clear that this approach is not sustainable in the long term. The agency needs to prioritize preparedness and invest in playbooks that can be quickly deployed in the event of an incident.
**Recommendations for Cybersecurity Agencies**
* **Develop comprehensive playbooks**: CISA should develop comprehensive playbooks that outline procedures for responding to various types of cybersecurity incidents. These playbooks should be regularly reviewed and updated to ensure they remain relevant and effective.
* **Establish clear communication channels**: The agency should establish clear communication channels with security researchers, allowing them to quickly notify the agency of potential incidents.
* **Prioritize workforce development**: CISA must prioritize workforce development, investing in training and resources that enable its staff to respond effectively to cybersecurity incidents.
In conclusion, CISA’s incident response plan was built during the incident, highlighting the need for prepared playbooks in place before an incident occurs. The agency must take steps to address these challenges and ensure that its workforce is equipped to handle the ever-evolving threat landscape.
