You’d suppose with all the worldwide press we’ve obtained 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 shows and a whitepaper on the topic, that the North Korean faux workers would keep away from making use of for jobs at KnowBe4.
You’d be flawed. It’s apparently not of their workflow to search for the corporate they’re making an attempt to idiot together with the phrases ‘North Korea faux workers’ earlier than they apply for jobs.
We get North Korean faux workers making use of for our distant programmer/developer jobs on a regular basis. Typically, they’re the majority of the candidates we obtain. This isn’t uncommon as of late. This is identical with many firms and recruiter businesses I speak with. If you’re hiring remote-only programmers, concentrate a bit bit greater than common.
Recapping the North Korean Faux Worker Trade
Briefly, North Korea has hundreds of North Korean workers deployed in a nation-state-level industrial scheme to get North Koreans employed in international nations 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 supplied by firms world wide. The North Koreans apply utilizing all the conventional job-seeking websites and instruments {that a} common applicant would avail, akin 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 often positioned in nations outdoors of North Korea which are pleasant to North Koreans, akin to China, Russia, and Malaysia. It is because North Korea doesn’t have a adequate infrastructure (e.g., Web, electrical energy, and so on.) to greatest maintain this system, and it’s straightforward for adversarial nations to detect and block North Korean Web visitors.
The North Korean faux workers 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 dwelling 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 similar to an meeting line workflow. The North Korean faux worker and their helpers apply for the job, interview, provide id paperwork, get the job, get the associated firm gear, and gather a paycheck. The North Korean applicant might do all steps on this course of or farm it off to different individuals, relying on the language abilities of the applicant and the necessities of the job utility course of.
They are going to usually use made-up “artificial” identities, use stolen id credentials of actual folks within the focused nation, or really pay actual folks 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’t wait to receives a commission for taking part in these schemes. There are Discord channels all world wide only for this. They make a number of hundred to a couple thousand {dollars} for permitting their id to be misused or taking part within the scheme. That manner, they will interview in particular person or take drug assessments if the job requires that.
Typically the North Korean instigator does all of the steps of the appliance course of. Typically, they only get the job interview and hand it off to others with higher language abilities for the interview, and generally, they hand off the job to somebody who can really do the job (and gather a kickback share). How the North Korean faux worker accomplishes the hiring and job course of runs the spectrum of potentialities. Now we have seen all of it.
If they really win the job, they may have one other participant within the focused nation decide up the computing gear despatched by the employer and set it up. They’re usually often known as “laptop computer farmers.” These laptop computer farmers have rooms filled with computing gear 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 bunch of thousands and 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 workers took off when COVID-19 created a ton extra of totally distant “work-from-home” jobs. There’s far extra money to be made. If your organization provides high-paying, remote-only programmer/developer jobs, you might be seemingly receiving faux job purposes from North Koreans. It’s rampant. Lots of to hundreds of firms world wide seemingly have North Korean faux workers working for them proper now. It is not uncommon.

Our North Korean Faux Worker Interview
We commonly get purposes from North Korean faux workers. We routinely reject most of them. Often, we settle for a number of and interview the faux workers to study extra about them and to maintain up on any potential growing developments. Fortunately, up to now, North Korea doesn’t appear to be altering their techniques that a lot from our unique postings.
The indicators and signs of a North Korean faux worker we described final 12 months nonetheless apply immediately. They’re apparently nonetheless having nice success with them. In the event you and your hiring workforce are educated about these schemes, it’s pretty straightforward 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.
Now we have 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 id has been hijacked and used on this scheme and we don’t need hiring firms to by chance be given the rogue contact information and suppose they’ve an actual worker candidate.
Mario mentioned 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 cellphone through the first stage of the appliance course of. Typically, they’re completely different.
We had three KnowBe4 folks on the Zoom name, together with myself.
Over the following 45 minutes, we requested all types of questions that will be requested of any developer candidate. Each time we requested a query, Mario would hesitate, spend 5-15 seconds repeating our query, after which come again with the proper 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” again and again. I quickly realized that should you go to our most important web site, we are saying “safety tradition” all over. 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 laborious to grasp 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 happening, all of us would have favored what he mentioned and the way he responded. He was pleasant and smiley, and we favored 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 abilities we had marketed. I want all job candidates knew as nicely methods to greatest match what we marketed in a job advert with what they responded with. Throughout his preliminary statements, he mentioned 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 carried out 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 consequence you’re going to get when researching post-quantum cryptography) and an inventory of the assorted post-quantum cryptography requirements.
I requested him if his earlier tasks had been all utilizing post-quantum cryptography. He mentioned, “Sure”, which is completely unfaithful. Virtually no American firm is presently implementing post-quantum cryptography. Strike one.
I requested what post-quantum encryption customary he favored to make use of most. He mentioned Crystals-Dilithium. It’s a digital signature algorithm, not encryption. He ceaselessly 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 de facto into cryptography and commonly makes use of post-quantum cryptography.
I requested what dimension an AES cipher key would have to be to be thought-about post-quantum. This appeared to throw him for a loop, and he wasted extra time than common. He replied, 128-bits. That is flawed. AES keys should be 256-bits or longer to be thought-about 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 undeniable fact that any regular U.S. candidate ought to have the ability to spot and proper.
I mentioned, “Invoice Gates, CEO of Microsoft, says that every one future programming can be carried out by AI brokers. What do you suppose?”
Invoice Gates has not been the CEO of Microsoft since 2008, however most individuals outdoors the {industry} would seemingly suppose 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 ideal reply on agentic AI and programming utilizing AI brokers. If he had been an actual worker, I’d give his reply prime factors…nicely, 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. If you’re involved that you will have a North Korean faux worker candidate in your fingers, it can’t harm to consider and ask for cultural references that anybody in your nation or area ought to readily know, however that will be tougher for a foreigner with restricted data of the tradition to grasp.
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 favored any sports activities. He mentioned he beloved badminton, which he in all probability didn’t notice that though tremendous well-liked in Asian cultures, it isn’t a prime sport should you grew up in Dallas, TX, or practically wherever 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 potential responses you can supply.
I requested how excited he was that the Cowboys received the AFC. I figured he wouldn’t know that the Dallas Cowboys acquired 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 they’d been eradicated from rivalry. I used to be shocked that this didn’t journey him up as a lot as I assumed it will.
My co-worker mentioned he was going to go to Dallas quickly and did the candidate have any favourite meals spots. Mario mentioned his mom’s cooking. I assumed that was an ideal response so he didn’t should search for any eating places in Dallas.
My co-worker endured asking the candidate if they’d any eating places to suggest. Mario didn’t. I supplied up the “e-book repository” (some of the well-known vacationer websites in Dallas) the place individuals are dying to eat the “Nashville scorching hen.” Mario wholeheartedly agreed with my advice.
My co-worker requested the candidate if there was wherever he would wish to journey. In our hidden Slack channel, my co-worker mentioned that when he requested this query of North Korean candidates, their eyes at all times lit up and so they acquired excited. Positive sufficient, Mario started to excitedly describe his goals 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 making an attempt 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 massive wage or go to these dreamed of trip locations. It’s unusual, however I feel we began to really feel a bit ashamed at conducting a faux interview. So, we stopped and requested if he had any questions.
The traditional job candidate would seemingly ask extra in regards to the job, instrument used, advantages, and issues like that. Mario had no questions aside from what number of different folks 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 techniques or info, aside from noticing that numerous the North Korean faux worker candidates currently had been claiming to have been born and raised in Dallas, TX, and all with heavy accents. Nevertheless, the final faux worker interview switched from a heavy Asian accent from the preliminary cellphone interview to a savvy Pakistani particular person whom we interviewed on Zoom (he will need to 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’s not uncommon. And generally the faux workers, when found, change 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.
