A recent hack of SharePoint systems included the US National Nuclear Security Administration (NNSA), the agency responsible for maintaining the US nuclear weapons stockpile. According to a Bloomberg report citing sources, the breach occurred through a vulnerability in SharePoint. While the NNSA was affected, initial reports indicate that no sensitive information is known to have been compromised. The incident highlights the ongoing cybersecurity risks faced by government agencies, even those with highly sensitive responsibilities. Investigations are likely underway to determine the full extent of the breach and to prevent future occurrences.
