The pseudonym "Mykola Yanchii" on LinkedIn [1] doesn't look real at all.
Click "More" button -> "About this profile", RED FLAGS ALL OVER.
-> Joined May 2025 -> Contact information Updated less than 6 months ago -> Profile photo Updated less than 6 months ago
Funny things, this profile has the LinkedIn Verified Checkmark and was verified by Persona ?!?! -> This might be a red flag for Persona service itself as it might contain serious flaws and security vulnerabilities that Cyber criminals are relying on that checkmark to scam more people.
Basically, don't trust any profile who's been less than 1yr history even though their work history dated way back, who has Personal checkmark, that should do it.

How am I supposed to become a real, trustable person on LinkedIn if I'm not already there?
weinzierl
Be a real, trustable person in real life. Let your real colleagues, acquaintances and friends contact you.
Aurornis
Create an account and let it age.
Seasoned accounts are a positive heuristic in many domains, not just LinkedIn. For example, I some times use web.archive.org to check a company's domain to see how far back they've been on the web. Even here on HN, young accounts (green text) are more likely to be griefing, trolling, or spreading misinformation at a higher rate than someone who has been here for years.

Yep. This is how the 3 major credit bureaus is the United States to verify your identity. Your residence history and your presences on the distributed Internet is the HARDES to fake.

This is why aged yet rarely used accounts are so valuable for hackers to gain control.
marcosdumay
> Create an account and let it age.
So, just hire one of those "account aging" services?
Because if you expect people to go there keeping everything up to date, posting new stuff, tracking interactions for 3 years and only after that they can hope to get any gain from the account... That's not reasonable.

All of the Year 1 Facebook accounts with more than a decade of activity that have been inexplicably banned and deleted in 2025 salute you.

Persona seems to rely solely on NFC with a national passport/ID, so simply stolen documents would work for a certain duration ...

You can click on the verification badge and see if the person has job verification. If not, that's a red flag. I never paid attention to this myself but I will in the future.
weinzierl
Some companies don't do job verification (for good reasons).
ohman876
Interesting, I didn't know there is such thing on Li! Is this done by past employers?
input_sh
You just verify that you have access to an email address that belongs to a company (@example.com) by entering a six digit code they send to your work email. This in theory verifies that you work there, but obviously nothing else like your actual position at the company.
From an attacker standpoint, if an attacker gains access to any email address with @example.com, they could pretend to be the CEO of example.com even if they compromised the lowest level employee.
koakuma-chan
You have to add it yourself and verify with your work email.
tracker1
I honestly didn't even know about the feature until my most recent job when LI offered to verify.

Whoever was operating that profile DFE'd. This is why you archive.

LMAO this post on his page has to be an AI generated map, it puts the UAE in Bangladesh.

Anyway I think we can add OP's experience to the many reasons why being asked to do work/tasks/projects for interviews is bad.

yea, And this team-bonding pic has a ghost finger -https://www.linkedin.com/feed/update/urn:li:activity:7379209...
On linkedin company pics, look for extra fingers.

"transforming real estate with blockchain" is the only red flag needed
johnnyanmac
A bit outdated. Now pitch "transforming real estate with AI" and you'd have $10m in startup money. No need to play penny slots.
nradov
Right, any sort of "blockchain" company is assumed to be a scam by default. I'm not trying to blame the victim here but anyone unaware of that reality has been living in a cave for the past few years.
nocoiner
Imagine if this guy had run the malicious code and transferred ownership of his house. Oops.
lawlessone
He would have to hand to over to them. "Code is law"

I had a very similar experience: https://kaveh.page/blog/job-interview-scam
I would never agree to run someone's code on my own machine that didn't come from a channel I initiated. The odd time I've ran someone else's code, ALWAYS USE A VM!
ep103
How are you guys spinning up vms, specifically windows vms, so quickly? I used to use virtual box back in the day, but that was a pain and required a manual windows OS install.
I'm a few years out of the loop, and would love a quick point in the right direction : )
RandomBacon
You take the time to set one up, then you clone it and use the clones for these things.
kwar13
For coding I normally run Linux VMs. But Windows should be doable as well. If you do a fresh install every time then sure it takes a lot of time, but if you keep the install in VirtualBox then it's almost as fast as you rebooting a computer.

I had someone who was targeting junior developers posting on Who Wants to Be Hired threads here on Hacker news. They reached out saying they liked my projects and had something I might be interested in, then set up an interview where they tried to get me to install malware.
dylan604
Maybe I should implement this as a weed out question during interviews. If the applicant is willing to download something without questioning it, then the interview can be ended there. Don't need someone working with me that will just blindly install anything just because.
ludicrousdispla
even some of the submissions on 'who is hiring?' can be sketchy

Name and shame.

Name and shame. It's the only way to help others.

Unfortunately there is not much to name. Someone going by Xin Jia reached out to me over email saying they had seen some of my work and that they had something similar they were working on and asked if I'd like to meet to discuss. He sent me a calendly link to schedule a time. The start of the meeting was relatively normal. I introduced my background and some things I am interested in.
It became clear that it was a scam when I started asking about the project. He said they were a software consulting company mostly based out of China and Malaysia that was looking to expand into the US and that they focused on "backend, frontend, and AI development" which made no sense as I have no experience in any of those (my who wants to be hired post was about ML and scientific computing stuff). He said as part of my evaluation they were going to have me work on something for a client and that I would have to install some software so that one of their senior engineers could pair with me. At this point he also sent me their website and very pointedly showed me that his name was on there and this was real.
After that I left. I'll look for the site they sent me but I'd imagine it's probably down. It just looked like a generic corporate website.
atropoles
I will say that it was good enough that with some improvement I could see that it might be very successful against people like me who are new to the software job market. A combination of being unfamiliar with what is normal for that kind of situation and a strong desire for things to go well is quite dangerous.
Also goes to show that anywhere there is desperation there will be people preying on it.

I’ve grown to depend on little snitch for this sort of thing. Always run in either Alert or Deny mode.
It is a little wild how many things expect to communicate with the internet, even if you tell them not to.
Example: the Cline plugin for vscode has an option to turn off telemetry, but even then it tries to talk to a server on every prompt, even when using local ollama.

A simple zero-config alternative using Linux-native containers seems to be sandbox-venv [1] for Python and sandbox-run [2] for npm ...

I agree, it's very valuable in these situations, although it can only minimize damage. For Littlesnitch/OpenSnitch users: avoid allow rules that apply to all apps. Malware can and has used even trusted websites like Github Gists to expose secrets extracted.
In any case, even if your firewall protects you, you'll still have to treat the machine as compromised.
jacquesm
OpenSnitch like functionality should come installed and activated by default.

Yep, Malwarebytes WFC really eases my mind.

Time to sandbox all code dev. Any good recommendations on sandboxing tools. Are docker / podman really secure enough ?
ashton314
Maybe a mini desktop computer hooked to a separate vlan that you nuke the disk every night at midnight?
DavidDodda
apparently not. someone in the comments suggested Incus. I haven't used it myself.
jrochkind1
Is it reasonable to wonder if they set up this attack to target OP specifically, the whole thing was customized for OP? Rather than a broad phishing of lots of developers or what have you.
Although now that makes me wonder -- can you have AI set up an entire fake universe of phishing (create the linked in profiles, etc) customized specifically for a given target.... en masse for many given targets. If not yet, very soon. Exciting.
Gualdrapo
I've been posting on HN's "who wants to be hired" and "freelancer" posts, and for the last couple months all I've got have been suspiciously similar emails from randoms asking me to schedule an online interview for a great "opportunity". They never state exactly what that "opportunity" is about. After some hours of not participating on it they will write again - have got three of them, from different gmail emails, all of them following the same script.

As the economy enters recession there's going to be more and more desperate people and criminals will exploit this.
As with OP's case, do not accept take home assignments unless they are FANG famous or very close to that.
In addition, opacity about opportunities should be #1 flag. There is no reason for someone serious to be opaque about filling a role and then increasing the amount of vetting. Also there is no reason to not telling you salary (this alone will help you filter out low paying jobs) for the same reason.
Usually hiring managers will look to always filter down list of candidates not increase them (unless they were lazy or looking to waste time).
johnnyanmac
My reasoning is even simpler: I've been ghosted or had interviews canceled way too much even by legitimate companies after doing their assignments in these last few years. If you want to give me homework, I need some of your time first.It's become too easy to waste mine.

> I was 30 seconds away from running malware on my machine.

Well that was a short article. Kudos to them, obviously candidates interested in a "blockchain company" are already very prone to getting scammed.
johnnyanmac
Can't wait in 4 years when we start saying the same thing about AI companies after the bubble pops.
titanomachy
Wild experience, thanks for sharing... I'll be even more careful about take-home assignments after this.
Honestly, the most surprising part to me is that you worked on the code for 30 minutes and fixed bugs without running anything.
I'm seeing red flags all over the story. "Blockchain" being the first one. The use cases for that are so small, it is a red flag in and of itself. Then asking you to run code before a meeting? No, that doesn't "save time", that is driving you to take actions when you don't yet know who is asking.
Still, I appreciate the write-up. It is a great example of a clever attack, and I'm going to watch out more for such things having read this post.
