Insider Threat Watchdog Sentenced After Spy Leak Plea

In a case that cuts to the heart of counterintelligence, a former Defense Intelligence Agency IT specialist has pleaded guilty to attempting to pass top-secret intelligence to individuals he believed were foreign spies. The twist: the spies were undercover FBI agents, and the man's job was to catch leakers.

From Watchdog to Leaker

Nathan Vilas Laatsch, 29, was arrested in May 2025 after an FBI sting caught him transmitting classified information for the second time. Laatsch had been a civilian DIA employee since 2019 and held top-secret clearance. In March 2025, he offered to transmit classified information to a foreign government—the identity of which has never been revealed, though court documents describe it as “a friendly foreign government.”

Notably, Laatsch was assigned to the DIA’s Insider Threat Division in spring 2025, a unit dedicated to identifying government workers who might leak classified information. According to the Justice Department, the FBI “became aware” of Laatsch’s offer in March.

Initial Email and FBI Response

Laatsch’s initial email, sent from a newly created account, had the subject line: “Outreach from USA Defense Intelligence Agency (DIA) Officer.” It introduced his role and the service he was willing to provide. In it, he stated he had access to “completed intelligence products, some unprocessed intelligence, and other assorted classified documentation.” The email included a picture of his government ID, with name and image redacted, and a username for an encrypted messaging platform.

The FBI replied on March 23, saying: “Good afternoon, I received your message and share your concerns. We are glad you reached out. I look forward to your response and learning more about your work.” Laatsch did not respond until April 14, after a follow-up on April 4. In subsequent conversations, he described what information he was offering.

Secret Notes and Sock Drops

On April 28, Laatsch entered his office and within 20 minutes began accessing classified information. Court documents state: “The defendant wrote multiple pages of notes, which he then removed from the notepad at his desk and folded into squares.” At the end of the day, he “bent under his desk, placed the folded papers into his socks, and departed the office.” He repeated this on April 29 and April 30, hiding papers in his lunchbox on the latter day.

The next day, per FBI instructions, he left a thumb drive in an Arlington, Virginia park. The FBI recovered the drive, which contained nine typed documents—eight classified as top-secret with sensitive compartmented information. The files included sensitive methods of intelligence collection, intelligence on foreign military exercises, and analysis of those exercises. Laatsch chose the files himself, based on assumed interests, and included a personal note expressing hope the tranche would prove his access.

“By his own admission, Laatsch betrayed his oath by offering classified information to a foreign government, the very thing he was supposed to prevent as an employee of DIA’s Insider Threat Division. Those entrusted with our nation’s most sensitive information must not exploit their access for personal gain - in this case offering to sell American secrets to buy foreign citizenship. The FBI and our partners will continue to hold accountable all those who betray the trust of the American people.”

Second Drop and Arrest

The undercover agent arranged a second intelligence drop for the following month. Between May 15 and May 27, Laatsch again transcribed classified information by hand, folding pages and placing them in his socks. On May 29, 2025, the FBI instructed him to go to a specific picnic table in the same park and electronically transfer the files from his personal computer. He agreed, executed the transfer to an FBI-controlled address, and was arrested on the spot. He waived his right to an attorney and admitted to the offenses.

Plea Agreement and Possible Sentence

Laatsch’s plea agreement recommends a sentence between 11 and 18 years, including time served. The court can impose a maximum sentence of life in prison and a $250,000 fine. The case highlights the inherent tension in insider threat programs: the very individuals tasked with monitoring others can themselves become threats.
