NSA Employee Pleads Guilty to Illegally Retaining National Defense Secrets

Nghia Hoang Pho faces up to eight years in prison for removing highly classified NSA data from workplace and storing it at home.

A software developer at the National Security Agencys elite Tailored Access Operations (TAO) hacking unit has pleaded guilty to unlawfully bringing home sensitive agency data that later ended up getting stolen from his personal computer by Russian state-sponsored actors.
Nghia Hoang Pho, 67, of Ellicott City, Md. faces up to eight years in prison for willfully retaining national defense information when he goes up for sentencing April 6, 2018.
Pho is the third NSA employee in recent years to be charged in connection with the misappropriation of highly classified information. His actions - and the public release of a big cache of NSA attack tools by the Shadow Brokers hacking crew last year - highlight the agencys continuing struggles protecting sensitive secrets more than four years after the Edward Snowden leaks.
There were clearly multiple failures that occurred. Both active and detective technical controls failed, says Simon Gibson, security architect at Gigamon and former Bloomberg CISO. To me, this whole situation reads like a problem any sloppy or overworked software shop might have. Only it’s not a software shop - its the NSA, Gibson says.
A court
document
released last Friday in connection with Phos
plea agreement
shows that he worked on highly classified and specialized projects at the agency. In his role as a TSA operative Pho had access to sensitive information on the cyber weapons and exploits developed at the NSA for surveillance and offensive cyber operations against foreign adversaries.
Pho has admitted to removing some of that data from his workplace and retaining it at home. The activity took place over a five-year period between 2010 and March 2015 and included both digital data and data in paper form. The plea agreement and a
statement
that the Justice Department released last week do not indicate why exactly Pho brought home the data despite knowing about the NSAs strict policies against the practice. However, the motive does not appear to have been malicious.
Pho stored some of the classified data from his workplace on a home computer protected by Moscow-based Kaspersky Labs antivirus software. Russian hackers are believed to have later discovered the NSA tools on Phos computer and stolen the data by exploiting Kasperskys antivirus software.
The NSA itself first learned of the Russian theft from Israeli cyberspies who had previously broken into Kasperskys AV system and was quietly monitoring it. The data theft incident is believed to be the primary cause for the US government formally banning federal agencies from using Kaspersky Labs products.
The security vendor has strongly rejected suggestions that it has helped Russian cyber actors search computers running Kasperskys AV software, for classified US data. Kaspersky Lab officials have noted that the companys automated malware scanners
discovered
the NSA hacking tools on Phos computer in an archive containing multiple known malware samples. The archive was uploaded to the Kaspersky AV network for further inspection and analysis. After Kaspersky Lab security analysts identified some of the data in it as belonging to the NSA they were instructed to promptly delete the data, the company has claimed.
Kaspersky Lab has said an internal investigation it conducted recently found no evidence at all that its researchers helped Russian agents find and steal the data from Phos computer.
Tom Kellermann, CEO of Strategic Cyber Ventures, describes Phos decision to take classified material home as disheartening. I am surprised that as a cybersecurity expert, his own operational security was subpar, he says. Even if this was allowed he should have been using robust American-made EDR [endpoint detection and response] security rather than what he had in place.
Pho is the third individual that has been charged with stealing or misappropriating NSA data in recent years. In 2016,
Harold Martin
, a long time NSA employee was arrested for stealing a staggering 50 terabytes of agency data in digital and hard-copy form over a 20-year period. In June this year, government contractor
Reality Winner
was accused of stealing a top-secret NSA document and providing it to the media.
The governments pursuit and prosecution of such individuals needs to extend all the way to the top, says Kathie Miley, chief operating officer at Cybrary. There is no question that transporting the materials to the NSA employee’s home was illegal. Therefore, it is not a surprise to see that the government has prosecuted and obtained a guilty plea from the defendant, Miley says.
What would be more interesting is to see the NSA prosecute other government officials who have committed equally illegal acts of transporting sensitive data to unauthorized networks, she says. The Russians have clearly shown their capacity and intent to infiltrate not only the homes of government employees, but [also] that of any infrastructure related to a politician and high-ranking official.
