A cyberattack on an IT company that provided services to the Sistema de Informações da República Portuguesa (SIRP) resulted in the exposure of unclassified data from Portuguese intelligence services. The SIRP confirmed this incident, stating that the data was extracted through an attack on the development server, which is used for testing.

This attack was reported on a cybercrime platform, where the sale of a dataset of 120 gigabytes of data was announced. The SIRP did not confirm the specific volume of data involved but emphasized that classified information was not accessed or compromised during the intrusion.

According to the SIRP, the company targeted by the attack was contracted to create the public websites for the SIRP, SIS, and SIED, highlighting the importance of strengthening the security of information handled by this entity.

It was stated that the server in question was designated for testing and that, in addition to data from the intelligence services, it may have included information from other unspecified entities.

The unclassified nature of the exposed data is significant, but the SIRP reiterated that there was no intrusion into systems that hold sensitive information, which may signal a warning about cybersecurity in similar contexts.

Authorities have continued to investigate the cyberattack to determine its origin and prevent future occurrences. The SIRP also urged institutions to reinforce their security measures.
