Podcast Summary: Click Here Episode - "Meet the ‘Kyles’ — North Korea’s Secret IT Warriors"

Introduction

In the March 4, 2025 episode of Click Here, hosted by Dina Temple-Raston of Recorded Future News, listeners are immersed in a gripping true story that unveils the covert operations of North Korea's secret IT workforce. This episode delves into how North Korean agents infiltrate legitimate companies under false identities to execute cyber schemes that fund the regime's activities. Through detailed storytelling and expert insights, the episode sheds light on the sophisticated methods employed by these operatives and the challenges faced by companies in safeguarding their digital environments.

The Hiring Process: Seeking the Perfect Candidate

The episode begins by highlighting the arduous process of hiring a principal software engineer at KnowBe4, a cybersecurity training company. Brian Jack, the Chief Information Security Officer at KnowBe4, explains the stringent requirements for the role:

Brian Jack [00:48]: "We were hiring for a principal software engineer that was gonna be writing code and applications on our IT team. Someone who was able to have lots of experience in writing full stack code."

The term "full stack code" refers to the ability to handle both frontend user interfaces and backend databases and logic. KnowBe4 sought someone with not only technical prowess but also leadership qualities—a combination often deemed a "unicorn" in the hiring world.

After posting the job, KnowBe4 received thousands of resumes. Among them stood out an applicant named Kyle, whose credentials seemed impeccable:

Dina Temple-Raston [02:14]: "And one stood out from someone named Kyle. He had a degree from the Hong Kong University of Science and Technology. Check. In Atlanta. Address, check. Impeccable coding credentials. Check, check, check."

Kyle seamlessly navigated the HR process, aced interviews, and was promptly hired. However, an unusual request raised initial suspicions:

Dina Temple-Raston [02:48]: "Then he sailed through the HR process, the interviews, smooth phone zoom, no red flags. And then he happily signed the job offer... Kyle asked KnowBe4 to send the laptop to a different state from the one on his employment form. Odd."

Despite this red flag, the company proceeded, embracing the norm of remote work.

Discovery of Malicious Activity: The First Red Flag

The night before Kyle's first day, KnowBe4's security systems detected unusual activity from his newly issued laptop:

Dina Temple-Raston [05:30]: "And when the malware was starting to run on that new laptop, they could see that too. And this malware, it wasn't subtle..."

The malware was actively searching for credentials and sensitive data, indicating a deliberate attempt to infiltrate the company's network. Initially, the team considered that Kyle's laptop might have been compromised before his employment—a concerning but plausible scenario.

Brian Jack recounts the immediate response:

Brian Jack [06:08]: "Our first instinct was to reach out to the individual and ask them what was going on."

An interaction on Slack revealed that Kyle was experiencing technical issues with his router, but his explanations began to fall apart when inconsistencies emerged, such as discrepancies in his marital status:

Dina Temple-Raston [07:22]: "He said his wife was having heart trouble and he needed to take her to the hospital. Only problem was, on all his forms, Kyle had listed himself as single. It was one red flag too many."

Facing mounting evidence, KnowBe4 decided to terminate Kyle's employment and secure the compromised laptop. However, suspicions lingered, prompting the company to seek external expertise.

Investigation and Revelation: Unmasking the North Korean Operative

To uncover the truth behind Kyle's activities, KnowBe4 enlisted the help of Google's Mandiant, a leading cybersecurity firm. The case was assigned to Michael Barnhart, a specialist in tracking North Korean Advanced Persistent Threats (APTs):

Michael Barnhart [09:07]: "I also go by Barney, and I do a lot of the North Korean operations over at Mandiant."

Barnhart's investigation revealed a startling truth: Kyle was not a legitimate software engineer from Atlanta but a North Korean IT agent designed to infiltrate the company. This revelation was part of a broader pattern of North Korean cyber operations aimed at evading global sanctions and funding the regime's activities.

North Korea's Cyber Operations: Strategies and Tactics

Barnhart provides an in-depth analysis of North Korea's covert IT strategies:

Michael Barnhart [13:15]: "You have Cambodia, Laos, even all the way as far out as Africa... They have their 'laptop farms' where individuals manage multiple devices to maximize revenue."

North Korea employs sophisticated methods to disguise their operatives, often using fake identities and leveraging the dark web to acquire necessary documents. They also utilize "laptop farms," where individuals manage numerous devices simultaneously, making it difficult to trace illicit activities back to the regime.

These operatives typically target tech-centric roles such as coders and animators, which can be performed remotely without the need for physical presence in an office. This flexibility allows them to juggle multiple jobs, increasing the flow of funds back to North Korea while minimizing detection risks.

Barnhart also highlights the use of automation and AI:

Michael Barnhart [13:41]: "They’re leaning into scripting, you see them leaning to automation and AI to help... making little tiny bots of themselves to go do work at these other places."

This automation enables operatives to maximize their efficiency and revenue streams without drawing suspicion.

Company's Response and Preventive Measures

In the wake of the Kyle incident, KnowBe4 implemented stringent measures to prevent future infiltrations. Brian Jack explains the new protocols:

Brian Jack [19:02]: "Now you guys have been provided the tools. You know what to look out for. You know, this is a thing. You're all fired if it happens again."

The company now scrutinizes resumes more meticulously, looking for patterns indicative of North Korean operatives, such as unusual email formats and repetitive keywords:

Brian Jack [19:08]: "There's kind of these email addresses that you can tell the format, or they'll use certain keywords like cool or ninja or.dev or then they add some numbers at the end..."

Additionally, KnowBe4 checks metadata and location tags in applicant images to spot signs of manipulation or falsification. This proactive approach has already led to the identification of several suspicious applicants, without proceeding to interviews.

Broader Implications: National Security and Beyond

The episode underscores the national security risks posed by such covert operations. FBI Special Agent Ashley Johnson discusses the broader impact:

Ashley Johnson [18:11]: "It could impact our national security if we have money going back to another government that forms any type of program or funds any type of program that could then be used against us adversarially."

The Kyle incident is emblematic of a larger scheme, where North Korea's cyber activities have led to significant financial losses and threats to national security. The FBI's recent cases involving hundreds of companies and millions of dollars highlight the pervasive nature of this threat.

Conclusion: Vigilance in the Digital Age

The Click Here episode concludes by emphasizing the evolving landscape of cybersecurity and the necessity for companies to remain vigilant. As remote work continues to offer flexibility, it also opens doors for sophisticated cyber infiltrations by state-sponsored actors. Brian Jack and Michael Barnhart advocate for continuous monitoring, advanced security protocols, and informed hiring practices to combat these hidden threats.
