Hacking the Pentagon... when personal data turns into an intelligence weapon

In cybersecurity, the most dangerous breaches are not always those that bring down a network or disable a system, but rather those that remain silent for months, gradually collecting data, and then leaving behind raw material that can be transformed into identity, influence, blackmail, or targeting. The best example of this is what happened with the Pentagon hack.

A data breach is no longer just a technical incident that can be contained by shutting down a server or changing passwords; Data itself has become part of the national security equation, and possessing it, analyzing it, and linking it to other sources is capable of producing a highly sensitive picture of people and institutions. Hence the importance of the hacking incident that affected one of the US Defense Manpower Data Center (DMDC) systems, which revealed a new level of risks associated with protecting personal data within institutions of a sovereign nature.

According to what was announced by the US Department of Defense and reported by American media, one of the DMDC systems witnessed unauthorized access to personally identifiable information during the period from October 2025 until July 2026, before the vulnerability was discovered and addressed. The latest published data indicate that the incident affected about 2.76 million people alive, in addition to 294 thousand deceased people, while the system maintains more than 60 million records related to military service members, civilians, contractors, and retirees. Veterans and military family members.

Dr. Muhammad Mohsen Ramadan, Head of the Artificial Intelligence and Cybersecurity Unit at the Arab Center for Research and Studies, said in exclusive statements to Al Arabiya.net/Al Hadath.net: What is striking here is not only the number of affected records, but the nature of the data itself; According to published notifications and reports, it included names, dates of birth, contact information, and social security numbers, in addition to information related to the military jobs and specializations of some individuals. Reports also indicated that the data in the affected files was not encrypted, an element that increases the sensitivity of the incident if an unauthorized party was able to access it.

He continued: From a cybersecurity perspective, the most important question is not: “How many people have been hacked?”, but rather: What can an attacker do with this data if he collects it and links it to other data? Individual personal data may seem of limited impact, but when the name is combined with date of birth, place of work, military specialty, means of communication, and data available from social media networks or other databases, we are faced with what is like building an integrated digital file for the targeted person.

Dr. Mohsen Ramadan believes that here data is transformed from mere administrative records into a tool that can be used in social engineering operations, impersonation, targeted phishing, attempts to seize accounts, or building maps of professional and personal relationships, and in military and security environments in particular, some of this information may be of additional value because it helps the attacker identify people, roles, and connections that can be targeted later.

He added: This point makes it necessary to distinguish between data hacking and misuse. The American authorities said that there have been no indications of misuse of the information that was accessed so far, but the lack of declared evidence of misuse does not mean that the data has become worthless to the attackers. Stolen data can be kept, analyzed, or later merged with other sources, and the continued unauthorized access for about nine months raises an important technical question about the time to discover the breach. In modern cybersecurity, it is not enough for an organization to be able to prevent an attack; It must also be able to detect abnormal behavior in the shortest possible time, determine the scope of the breach, isolate affected accounts or systems, and then analyze digital evidence before the incident turns into a larger crisis.

He added: Here the concept of Mean Time to Detect - MTTD appears, i.e. the average time required to detect the incident, and the concept of Mean Time to Respond - MTTR, i.e. the time required for response and treatment. The longer the attacker remains inside the digital environment without detection, the greater the opportunity to collect data, expand within the systems, and achieve additional goals. The most dangerous lesson in this incident is that the vulnerability was not necessarily in a classified or top-secret system in order for it to have a strategic impact. The database may be unclassified, but it contains personal and professional information that can be highly sensitive to collect and analyze.

He concluded: This changes our traditional concept of protecting national security. National security is no longer limited to protecting weapons systems or command and control networks. Rather, it includes protecting the digital identity of individuals, job data, location information, professional relationships, and personal records. What is more dangerous is that artificial intelligence adds a new layer to this equation. The problem is no longer just the attacker's ability to obtain millions of records, but rather his ability to quickly analyze massive amounts of data, discover patterns and relationships, classify targets, and create highly personalized fraudulent messages. Thus, artificial intelligence can transform a “huge amount of data” into usable intelligence in a much shorter time than was previously possible. Therefore, protecting sensitive data should not depend on the idea of ​​“100% intrusion prevention,” because this goal is unrealistic in an evolving and constantly changing threat environment. The most mature goal is to build a system that makes hacking difficult, detecting it quickly, containing it immediately, and having a limited impact even if the attacker succeeds in bypassing some barriers.

For his part, former Egyptian Assistant Minister of the Interior, Major General Mohamed Rajai, said in exclusive statements to Al Arabiya.net/Al Hadath.net: One of the most important measures in this context is the application of the Zero Trust principle, so that no user, device, or application obtains virtual trust simply because it is present within the network. It is also necessary to apply as little permission as possible, divide networks and data into separate domains, encrypt sensitive data both during storage and transmission, monitor file access operations, and use EDR/XDR technologies to monitor and respond to abnormal behavior.

He continued: Periodic reviews must also be conducted of old systems, especially file sharing systems and databases that contain huge personal information. Because a system that has been operating for years without an apparent incident is not necessarily a safe system, but rather it may simply be a system whose security limits have not been adequately tested.

He added: More important than technology is data governance: What data do we keep? Why do we keep it? Who can access it? How long do we keep it? Do we really need to store all this data in one place? There is an important security rule that we must reaffirm: the greater the amount of sensitive data collected in one warehouse, the greater the value of this warehouse as a target for the attacker.

Major General Muhammad Rajai sent an awareness message to every institution, governmental or private: Do not wait for a hack to begin protecting data. True cybersecurity begins before the attack, continues during it, and does not end once the vulnerability is fixed. He also sent a message to users and individuals: Your personal data is not just ordinary information; It's part of your digital identity. Phone number, date of birth, email address, employer, photos, location data, and even job details may seem separate, but when combined they can create an accurate digital picture of you.

Major General Rajai pointed out that this is why we should not look at data leakage as just passing technical news, as every information that is revealed may become part of a future attack, and every unprotected database may turn into an entry point for more complex attacks. The most important message that the Pentagon incident reveals is that the cyber battle does not begin when the attacker presses the hack button; Rather, it starts from the moment the data becomes accessible without adequate protection.

He concluded: The nature of wars and threats has changed. The attacker no longer always needs to bring down a facility or disrupt a network in order to achieve a strategic effect. Sometimes it is enough for him to know who you are, where you work, what your job is, who you deal with, and how you can be reached. In a world where data turns into power, protecting data is no longer a technical luxury, but rather has become an integral part of protecting national security.
