Summary

According to sources, starting in August 2012 and for a duration of four months, a group with Tactics, Techniques and Procedures reputed as Iran conducted an intrusion into the US Navy's unclassified administrative network (800 000 users, 2500 sites), during a wider operation called Operation Cleaver. The attackers would have exploited a vulnerability on a public-facing website before pivoting onto the intranet.

Sources report that no data was stolen in the attack but that, however, $10 M were necessary to repair the damages caused by the attack.

Recommendations to Defence to reduce Intrusion risks:

Implement strong access controls and authentication mechanisms to limit unauthorized access, such as Multi Factor Authentication.
Regularly update and patch software and systems to address known vulnerabilities.
Use Network Intrusion Detection Systems (NIDS) to monitor and block suspicious activities.
Segment your network to limit lateral movement by attackers in case of a breach.
Educate your employees about phishing attacks and social engineering tactics to prevent credential theft.
