Understanding How Teixeira Leaked Documents is Key, But Information Is Missing

The memo from the Secretary of Defense for all departments of defense personnel, dated July 30, is the Pentagon’s response to Teixeira’s classified document leak incident.

As the Washington Post reported in 2023, Teixeira had access to the Defence Department’s Joint Worldwide Intelligence Communication System (JWICS). With that high-level security clearance Teixeira could access thousands of classified documents.

According to the official public version, Teixeira printed out classified material, which he extracted from the secure locations and took home. Once home, he allegedly photographed the documents and uploaded them online.

However, the Pentagon’s memo does not just mandate measures to deal with documents being printed and exiting secure locations. It clearly says that the use of personal electronic devices within top-secret facilities must be prohibited and calls for new tech to mitigate insider wireless threats.

Experts and Federal Contractors Talk Wireless Security Failures Inside the DoD

Michael Arcamone, Former CEO of InQuest and Now Chief Strategy Officer and VP of Federal Sales at OPSWAT, spoke to Techopedia about the issue.

“The use of personal or portable electronic devices (PEDs) within secure facilities poses significant security risks. Wireless threats include unauthorized data transmissions via Bluetooth, Wi-Fi, or cellular networks, which adversaries can exploit for espionage or data exfiltration.”

Arcamone explained that to counter these threats facilities should employ advanced sensors at each entry point and throughout the workspace. These sensors are designed to detect wireless devices and trigger alarms immediately, ensuring that no unauthorized personal electronic device operate within secure areas.

Additionally, these systems work in tandem with monitoring solutions for print jobs, enforcing a “no read up or write down” policy and conducting periodic inspections when personnel exit the facility.

On the other hand, Dr. Brett Walkenhorst, CTO of Bastille, a wireless threat intelligence provider, told Techopedia that according to openly available media reports, the former Airman Teixeira wrote summaries of classified reports and extracted them from secure areas, later uploading those summaries in text form.

“He also printed copies of such reports, physically removed those documents, and later took photos of them to upload to external servers,” Walkenhorst said. “Though a phone was involved in taking photos of classified documents, those photos were likely not captured inside secure areas.”

Nizel Adams, CEO and Principal Engineer at Nizel Co, an IT company registered as a federal contractor and experienced in government DoD systems, told Techopedia that the guards seem to have just let Teixeira walk into the facility with a phone multiple times — “which is a huge error”.

“I think in the average person’s mind, they think something out of a spy novel or hacker movie took place. Jack Teixeira doesn’t seem to have done anything remotely complicated, and I doubt he has the skillset to do so.

“Security was just so lax that he was able to sneak a phone into the SCIF.

“As the ‘IT guy,’ Teixeira was most likely less scrutinized than other individuals and already had high-level access to documents just by the nature of the work.”

Combating Insider Malicious Wireless Threats

As mentioned, the Pentagon memo mandates the deployment of mitigation measures to combat wireless threats posed by personal or portable electronic devices. We asked Walkenhorst from Bastille to walk us through these threats and why they are a big focus.

Walkenhorst said that the DoD has long understood the risks associated with wireless device threat capabilities, prompting policies excluding electronic devices from secure areas.

“Today, those risks are greater than ever, driven primarily by three factors: One, the ubiquity of wireless-capable devices. Two, the invisibility of the signals they send. Three, the vulnerability of the protocols they utilize.”

Because wireless devices are available to everyone, everywhere, they lower the technical barrier that malicious insiders need to run their exfiltration campaigns.

Additionally, wireless signals are challenging to detect and monitor, despite advancements made in wireless security.

“To date, over 3000 wireless-related CVEs (Common Vulnerabilities and Exposures) have been published in the NIST database with ever-increasing numbers in recent years,” Walkenhorst said.

“These numerous vulnerabilities represent the tip of the iceberg in terms of what is possible.”

Examples of wireless attacks include rogue cell towers, smartphone spyware, physical malware injection, Evil Twin attacks, password spraying, Distributed Denial of Service (DDos) attacks, session hijacking, and credential sniffing, to name just a few.

The Role of the Private Sector in Pentagon Cybersecurity

Techopedia consulted with experts to understand just how much of a system overhaul the Pentagon’s memo represents and whether the private sector’s role could be significant.

Walkenhorst from Bastille said that many of the requirements listed in the memo can be met with the systems and technologies that the government already has.

However, these systems and technologies need to be recognized and implemented in a more robust and integral manner. Additionally, other requirements within the memo call for new capabilities, Walkenhorst explained.

“The most notable of these being the need to introduce technology solutions that detect and monitor unauthorized electronic devices.”

Not Just New Tech, But PenTests and Vulnerability Scans Too

Adams from Nizel Co added that the private cybersecurity sector doesn’t just deploy measures for the government but they assist in evaluating weaknesses within it.

“Security risk assessments consist of things like penetration testing, identifying high-risk users through things like phishing tests, etc. From the information that is gathered from (evaluations and attack simulations), solutions are recommended.”

Adams added that other gaps in security should be considered, such as signal jammers and scanners at checkpoints throughout the facility and a comprehensive and exhaustive system in place to monitor who enters SCIF, how long they spend there, whether any document is printed, and more.

All the SCIF user logs should be submitted in reports to the responsible security supervisors.

The Bottom Line: Will All SCIFs and SAPFs Facilities Meet the Deadline?

Mandatory government deployment of cybersecurity measures can be complex and challenging for agencies and those involved, especially when a clock is ticking. Will facilities meet the deadline and what happens if it is not met?

Walkenhorst from Bastille said the memo requirements involve changes that may require additional time, funding, policy updates, or operational support.

“For those DOD components that can’t meet the programming request deadline, I think we’ll see continuing guidance from the DOD to help bring them into compliance as soon as possible.”

The biggest obstacle for the Pentagon is the sheer scale of the digital attack surface which spans across the entire DoD. Additionally, the memo calls for an integration of systems for joint capability to achieve greater visibility and analysis of on-network and off-network activities.

Finally, funding remains a top priority, especially for the deployment of wireless electronic device detection solutions — a new component that does not currently exist inside the DoD.

However, despite these challenges, Adams, from Nizel Co., is optimistic and confident that the deadline can be met.

“A lot of the wording in the memo is just code for ‘do your job’ and ‘don’t allow people to walk into a SCIF with electronics’. No doubt it has already been rectified, and those processes are in place.”

As far as installing signal jammers, Adams assures that these are relatively easy and can be installed in a day or two.

“The scanning system would take some time to evaluate and introduce it into the environment as proper controls need to be put in place and personnel trained, but it can still be implemented by the deadline,” Adams said.
