TL;DR
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) left sensitive credentials in a public GitHub repository for about six months. The leak included passwords and keys for internal systems, but CISA states no sensitive data was confirmed as compromised. The incident highlights ongoing cybersecurity risks within government agencies, such as the dangers of leaked SSH keys.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) left its cloud storage credentials publicly accessible on GitHub for an undetermined period, according to Krebs on Security. The agency stated that no sensitive data was confirmed as compromised, but the exposure raised alarms about cybersecurity protocols within a federal agency responsible for protecting critical infrastructure.
According to Krebs on Security, CISA’s public GitHub repository, named ‘Private-CISA,’ contained files with plaintext passwords, security tokens, and administrative credentials for internal systems. The repository was created in November of the previous year, and the exposure lasted approximately six months before being addressed over the weekend, illustrating how human error in the development pipeline can lead to security breaches.
The exposed files included ‘importantAWStokens,’ which contained administrative credentials for three Amazon AWS GovCloud servers, and ‘AWS-Workspace-Firefox-Passwords.csv,’ listing plaintext usernames and passwords for dozens of internal CISA systems, including a system called ‘LZ-DSO,’ likely short for ‘Landing Zone DevSecOps.’
Why It Matters
This incident underscores vulnerabilities in federal cybersecurity practices, especially regarding the handling and storage of sensitive credentials, such as leaked SSH keys. The exposure of internal system passwords and tokens poses risks of unauthorized access, data breaches, and potential exploitation by malicious actors. It also raises questions about the effectiveness of internal safeguards and oversight within government agencies tasked with cybersecurity.

Background
CISA, established in 2018, has faced ongoing challenges, including political turmoil and leadership instability, especially during the Trump administration and its aftermath. The agency’s role is to secure U.S. infrastructure from cyber threats, making its own cybersecurity practices critical. Previous incidents have highlighted vulnerabilities across government agencies, but this leak is notable for the severity of exposed credentials and the length of time they were publicly accessible.
