You’d assume with all the worldwide press now we have acquired due to our public announcement of how we mistakenly employed a North Korean faux worker in July 2024, adopted by our a number of public displays and a whitepaper on the topic, that the North Korean faux staff would keep away from making use of for jobs at KnowBe4.
You’d be improper. It’s apparently not of their workflow to lookup the corporate they’re attempting to idiot together with the phrases ‘North Korea faux staff’ earlier than they apply for jobs.
We get North Korean faux staff making use of for our distant programmer/developer jobs on a regular basis. Generally, they’re the majority of the candidates we obtain. This isn’t uncommon lately. This is identical with many firms and recruiter companies I discuss with. In case you are hiring remote-only programmers, concentrate slightly bit greater than ordinary.
Recapping the North Korean Pretend Worker Business
In brief, North Korea has 1000’s of North Korean staff deployed in a nation-state-level industrial scheme to get North Koreans employed in international international locations to gather paychecks till they’re found and fired.
[Note: Due to UN sanctions, it is illegal to knowingly hire a North Korean employee throughout much of the world.]
To perform this scheme, North Korean residents apply for remote-only programming jobs provided by firms all over the world. The North Koreans apply utilizing all the conventional job-seeking websites and instruments {that a} common applicant would avail, equivalent to the corporate’s personal job hiring web site and devoted job websites like Certainly.com.
The North Koreans work as a part of bigger groups, usually consisting of dozens to over 100 faux candidates. They’re normally situated in international locations outdoors of North Korea which can be pleasant to North Koreans, equivalent to China, Russia, and Malaysia. It’s because North Korea doesn’t have a ok infrastructure (e.g., Web, electrical energy, and many others.) to greatest maintain this system, and it’s simple for adversarial international locations to detect and block North Korean Web visitors.
The North Korean faux staff work in groups with a controlling supervisor. They usually stay in dormitory-style housing, eat collectively, and work in very managed circumstances. They don’t have a lot particular person freedom. Their households again house are used as hostages to maintain the North Korean individuals in line and dealing. They get jobs and earn paychecks, however the bulk of the earnings is distributed again to North Korea’s authorities, usually to fund sanctioned weapons of mass destruction packages.
The scheme is very like an meeting line workflow. The North Korean faux worker and their helpers apply for the job, interview, provide identification paperwork, get the job, get the associated firm tools, and acquire a paycheck. The North Korean applicant could do all steps on this course of or farm it off to different individuals, relying on the language expertise of the applicant and the necessities of the job software course of.
They’ll usually use made-up “artificial” identities, use stolen identification credentials of actual individuals within the focused nation, or really pay actual individuals of Asian ancestry who stay within the goal nation to take part. It seems there’s a burgeoning sub-industry of college-aged males of Asian ancestry who can not wait to receives a commission for taking part in these schemes. There are Discord channels all all over the world only for this. They make just a few hundred to a couple thousand {dollars} for permitting their identification to be misused or taking part within the scheme. That means, they’ll interview in particular person or take drug exams if the job requires that.
Generally the North Korean instigator does all of the steps of the applying course of. Generally, they only get the job interview and hand it off to others with higher language expertise for the interview, and typically, they hand off the job to somebody who can really do the job (and acquire a kickback proportion). How the North Korean faux worker accomplishes the hiring and job course of runs the spectrum of prospects. We’ve got seen all of it.
If they really win the job, they’ll have one other participant within the focused nation choose up the computing tools despatched by the employer and set it up. They’re usually often known as “laptop computer farmers.” These laptop computer farmers have rooms stuffed with computing tools sitting on tables, marked with an identifier of what pc belongs to what firm (to maintain them straight). They energy on the laptops and provides the faux North Korean worker distant entry to the laptop computer.
Utilizing this scheme, North Korea has illegally “earned” a whole lot of hundreds of thousands of {dollars} to fund its unlawful weapons packages over the previous few years.
There have been North Korean faux distant part-time contractors for over a decade, however the faux full-time distant staff took off when COVID-19 created a ton extra of totally distant “work-from-home” jobs. There may be far more cash to be made. If your organization provides high-paying, remote-only programmer/developer jobs, you’re seemingly receiving faux job functions from North Koreans. It’s rampant. Lots of to 1000’s of firms all over the world seemingly have North Korean faux staff working for them proper now. It’s common.

Our North Korean Pretend Worker Interview
We recurrently get functions from North Korean faux staff. We routinely reject most of them. Often, we settle for just a few and interview the faux staff to be taught extra about them and to maintain up on any attainable growing developments. Fortunately, thus far, North Korea doesn’t appear to be altering their ways that a lot from our unique postings.
The indicators and signs of a North Korean faux worker we described final 12 months nonetheless apply right this moment. They’re apparently nonetheless having nice success with them. Should you and your hiring workforce are educated about these schemes, it’s pretty simple to acknowledge and mitigate them. You simply should know and search for the indicators and signs.
We just lately interviewed “Mario” supposedly from Dallas, Texas. Right here’s part of his resume.
We’ve got hidden Mario’s final title and call info as a result of it’s the title of an actual American who is probably going unaware that his identification has been hijacked and used on this scheme and we don’t need hiring firms to unintentionally be given the rogue contact information and assume they’ve an actual worker candidate.
Mario stated he was an American citizen who was born and raised in Dallas. Regardless of this, he had a reasonably robust Asian accent (seemingly North Korean). The Mario who confirmed up for our Zoom interview had the identical voice because the Mario we interviewed over the telephone through the first stage of the applying course of. Generally, they’re totally different.
We had three KnowBe4 individuals on the Zoom name, together with myself.
Over the subsequent 45 minutes, we requested all kinds of questions that might be requested of any developer candidate. Every time we requested a query, Mario would hesitate, spend 5-15 seconds repeating our query, after which come again with the right reply…more often than not. It was clear that Mario or somebody taking part with him was typing the query topic right into a Google search or AI engine and repeating the outcomes.
Mario began off by saying how he had a particular curiosity in social engineering (you don’t say) and safety tradition. He talked about “safety tradition” time and again. I quickly realized that for those who go to our major web site, we are saying “safety tradition” in all places. He was repeating phrases he discovered on our web site.
However he was very pleasant and smiling, and his English was closely accented, however not tremendous exhausting to know more often than not. I’d say that based mostly solely on this primary a part of the interview, if we had been unaware of what was occurring, all of us would have preferred what he stated and the way he responded. He was pleasant and smiley, and we preferred him.
Mario claimed on his resume and in particular person to have programmed for Amazon, Salesforce, and IBM. He supposedly has the precise superior programming expertise we had marketed. I want all job candidates knew as properly the best way to greatest match what we marketed in a job advert with what they responded with. Throughout his preliminary statements, he stated he had a private curiosity in cryptography and safety. When it got here time for me to ask technical questions, I used his talked about pursuits as the idea for my questions.
I began off by asking if he had ever executed post-quantum cryptography and if he had applied it in his previous tasks. He hesitated, repeated the query, after which gave me a superb dissertation on post-quantum cryptography, together with mentioning NIST (which might be the highest search end result you’ll get when researching post-quantum cryptography) and a listing of the assorted post-quantum cryptography requirements.
I requested him if his earlier tasks had been all utilizing post-quantum cryptography. He stated, “Sure”, which is completely unfaithful. Nearly no American firm is at the moment implementing post-quantum cryptography. Strike one.
I requested what post-quantum encryption normal he preferred to make use of most. He stated Crystals-Dilithium. It’s a digital signature algorithm, not encryption. He incessantly blended up encryption algorithms, like AES, with hashes (e.g., SHA-2) and digital signatures (e.g., Diffie-Hellman). Strike two for somebody who is absolutely into cryptography and recurrently makes use of post-quantum cryptography.
I requested what dimension an AES cipher key would should be to be thought of post-quantum. This appeared to throw him for a loop, and he wasted extra time than ordinary. He replied, 128-bits. That is improper. AES keys should be 256-bits or longer to be thought of resilient in opposition to quantum cryptography. Strike three on the technical questions. He wrongly answered each technical query I requested.
At this level, I made a decision to throw out a random unhealthy proven fact that any regular U.S. candidate ought to be capable of spot and proper.
I stated, “Invoice Gates, CEO of Microsoft, says that each one future programming shall be executed by AI brokers. What do you assume?”
Invoice Gates has not been the CEO of Microsoft since 2008, however most individuals outdoors the {industry} would seemingly assume Invoice Gates was nonetheless the CEO as a result of that’s how the media usually references him…because the “former” CEO of Microsoft. He’s nonetheless a cultural icon related to Microsoft. That is the kind of mistake {that a} North Korean worker who doesn’t have nice entry to the Web would make.
And certain sufficient, Mario repeated the truth that Invoice Gates was the CEO of Microsoft (as an alternative of the present CEO, Satya Nadella). Mario did give an important reply on agentic AI and programming utilizing AI brokers. If he had been an actual worker, I’d give his reply high factors…properly, apart from not noticing my CEO switch-a-roo.
Lastly, with the technical a part of the interview over, we switched to the “private” questions. In case you are involved that you might have a North Korean faux worker candidate in your palms, it can not harm to consider and ask for cultural references that anybody in your nation or area ought to readily know, however that might be more durable for a foreigner with restricted information of the tradition to know.
Certainly one of my co-interviewers requested him what he did in his free time. This appeared to shock him. My co-worker requested if he preferred any sports activities. He stated he cherished badminton, which he in all probability didn’t understand that though tremendous common in Asian cultures, it isn’t a high sport for those who grew up in Dallas, TX, or almost anyplace in America. Positive, there are many individuals who play badminton (particularly People of Asian-American ancestry), however it’s an unlikely response out of all of the attainable responses you can provide.
I requested how excited he was that the Cowboys received the AFC. I figured he wouldn’t know that the Dallas Cowboys obtained creamed and didn’t win the AFC. For one, they’re within the NFC and never the AFC convention division. He once more hesitated…however then appeared to get that I used to be mentioning the Dallas Cowboys and that that they had been eradicated from competition. I used to be stunned that this didn’t journey him up as a lot as I believed it will.
My co-worker stated he was going to go to Dallas quickly and did the candidate have any favourite meals spots. Mario stated his mom’s cooking. I believed that was an important response so he didn’t should lookup any eating places in Dallas.
My co-worker endured asking the candidate if that they had any eating places to advocate. Mario didn’t. I provided up the “guide repository” (one of the crucial well-known vacationer websites in Dallas) the place individuals are dying to eat the “Nashville sizzling rooster.” Mario wholeheartedly agreed with my suggestion.
My co-worker requested the candidate if there was anyplace he would need to journey. In our hidden Slack channel, my co-worker stated that when he requested this query of North Korean candidates, their eyes at all times lit up they usually obtained excited. Positive sufficient, Mario started to excitedly describe his desires of visiting Paris and South Africa.
I feel it was at this level that all of us started to have some empathy. Sure, we had been coping with a faux job candidate who was attempting to steal our cash (or worse), however in actuality, this was a younger man seemingly compelled to do what he was doing, destined by no means to obtain any huge wage or go to these dreamed of trip locations. It’s unusual, however I feel we began to really feel slightly ashamed at conducting a faux interview. So, we stopped and requested if he had any questions.
The conventional job candidate would seemingly ask extra in regards to the job, device used, advantages, and issues like that. Mario had no questions aside from what number of different individuals we had been interviewing and the way he was doing within the job interview.
We ended the job interview. We had not picked up any new ways or info, aside from noticing that quite a lot of the North Korean faux worker candidates currently had been claiming to have been born and raised in Dallas, TX, and all with heavy accents. Nonetheless, the final faux worker interview switched from a heavy Asian accent from the preliminary telephone interview to a savvy Pakistani particular person whom we interviewed on Zoom (he should have been the employed handoff for the interview).
I’ve now spoken with many dozens of different employers who’ve both virtually employed a North Korean faux worker or employed them. It isn’t uncommon. And typically the faux staff, when found, swap to a ransomware encryption scheme or steal your organization’s confidential information and ask for a ransom, so it isn’t at all times nearly getting the paycheck.
Employers beware.
