    Study Notes

    • Jonathan Toebbe, a 42-year-old nuclear engineer in the US Navy, is accused of selling restricted military intelligence to a foreign government.
    • Toebbe, who had two active Top Secret security clearances, aimed to gain $5 million in cryptocurrency.
    • The engineer stole data about the Virginia class of submarines, which are crucial to US military operations.
    • Toebbe’s scheme involved selling thousands of documents, schematics, and charts to a foreign government.

    The Scheme

    • Toebbe sent an anonymous note and SD card to a foreign government address in April 2020.
    • The SD card contained encrypted data that required a digital key to unlock.
    • The FBI intercepted the SD card and initiated communication with Toebbe using a ProtonMail account under the pseudonym "BOB."
    • Toebbe used the pseudonym "ALICE" and was cautious about face-to-face meetings.

    The FBI’s Social Engineering Tactics

    • The FBI used social engineering tactics to convince Toebbe to meet in person.
    • Toebbe was hesitant due to security concerns and proposed an electronic exchange of data for Monero cryptocurrency.
    • The FBI agreed to the electronic transfer and continued to push for an in-person data drop, ultimately proposing a secret signal in Washington D.C. over Memorial Day weekend.
    • Toebbe, believing the signal was a sign of good faith from the foreign government, agreed to the in-person drop.

    The Data Drops

    • Toebbe and the FBI agent planned to communicate using weekend exchanges at parks and trails.
    • Toebbe was increasingly comfortable with the in-person exchanges, even suggesting plausible deniability for his actions.
    • Toebbe made several data drops, hiding SD cards in various locations, including between slices of bread inside a plastic bag and inside a chewing gum wrapper.

    Toebbe’s Arrest

    • After a final data drop on October 9, 2021, Toebbe was arrested in West Virginia along with his wife, who was aware of the scheme.
    • The final SD card contained restricted data related to submarine nuclear reactors.

    The Incident’s Implications

    • The case raises concerns about insider threats and the need for robust security measures.
    • Organizations should implement safeguards to prevent and detect insider threats.
    • The case highlights the use of social engineering tactics by cybercriminals and the importance of security awareness training for employees.
