European Space Agency (ESA) External Servers Breached
The European Space Agency (ESA) confirmed a cybersecurity breach affecting a small number of external servers used for collaborative engineering activities. A threat actor, "888", claimed to have exfiltrated over 200GB of data, including source code, CI/CD pipelines, API and access tokens, confidential documents, configuration files, Terraform files, SQL files, and private Bitbucket repositories. ESA stated that only unclassified data was compromised, with no impact on core mission or classified systems.
