Nördnytt! 🤓LinkedIn is illegally searching your computer
- haswell - 24886 sekunder sedanThe headline seems pretty misleading. Here’s what seems to actually be going on:
> Every time you open LinkedIn in a Chrome-based browser, LinkedIn’s JavaScript executes a silent scan of your installed browser extensions. The scan probes for thousands of specific extensions by ID, collects the results, encrypts them, and transmits them to LinkedIn’s servers.
This does seem invasive. It also seems like what I’d expect to find in modern browser fingerprinting code. I’m not deeply familiar with what APIs are available for detecting extensions, but the fact that it scans for specific extensions sounds more like a product of an API limitation (i.e. no available getAllExtensions() or somesuch) vs. something inherently sinister (e.g. “they’re checking to see if you’re a Muslim”).
I’m certainly not endorsing it, do think it’s pretty problematic, and I’m glad it’s getting some visibility. But I do take some issue with the alarmist framing of what’s going on.
I’ve come to mostly expect this behavior from most websites that run advertising code and this is why I run ad blockers.
- ef2k - 10066 sekunder sedanA few years ago, intentionally fingerprinting or tracking your users without disclosure was spyware and unethical. Alas, here we are.
Anyway, what they're calling "spectroscopy", is a combination of extension probing and doing residue detection (looking for what extensions might leave behind in the DOM).
An ad blocker is not necessarily equipped to help since the script is embedded with the application code. Since they're targetting Chrome, switching browsers will help with the probing but not the detection part and you'll still be fingerprinted.
The only way forward is for browser vendors to offer a real privacy or incognito mode where sites are sandboxed by default. When the default profile is identical across millions of users there won't be anything unique to fingerprint.
- Beestie - 11555 sekunder sedanI don't have a linkedin acct. So imagine my shock when I "googled" myself and found a linkedin profile connecting my name to a company I presently have a consulting arrangement with (1099 not W2). I went ballistic and fired off an email to the consulting firm to take down the profile immediately or face legal action (a bluff). Couple days later, the company forwarded an email they received from linkedin confirming the profile had been taken down.
So this is just a heads up that even if you don't have a linkedin account, they will create one on your behalf so might better check (assuming you neither have nor want one).
- andersonpico - 25002 sekunder sedanthis is a massive violation of trust
> The scan doesn’t just look for LinkedIn-related tools. It identifies whether you use an Islamic content filter (PordaAI — “Blur Haram objects, real-time AI for Islamic values”), whether you’ve installed an anti-Zionist political tagger (Anti-Zionist Tag), or a tool designed for neurodivergent users (simplify).
- cenal - 8248 sekunder sedanThere is no reason to trust any big tech company. Folks should be using containers in their browser if they care about privacy. I previously published a LinkedIn container extension for FireFox: https://addons.mozilla.org/en-US/firefox/addon/linkedin-cont... although as many know you can achieve the same results with Firefox containers without a specific extension like mine if you configure it manually.
I will work on an improvement to that extension so that it can block these scans if they attempt them in firefox.
- Johnny555 - 12690 sekunder sedan>the fact that it scans for specific extensions sounds more like a product of an API limitation (i.e. no available getAllExtensions() or somesuch)
Why should a website be able to scan for extensions at all?
Or if there's a legitimate need (like linkedin.com wants to see if you installed the linkedin extension), leave it up to the extension to decide if it wants to reveal itself. The extension can register a list of URL patterns it will reveal itself to. So the linkedin extension might reveal itself only to *.linkedin.com, a language translation extension might reveal itself to everyone, and an adblocker extension might not choose to reveal itself to anyone.
- lxgr - 20540 sekunder sedanAll I'm seeing is that Chrome apparently is failing to properly sandbox websites against extension fingerprinting.
Sure, this can be solved at the legal layer, but in this case, there seems to be a much simpler and more effective technical solution, so why not pursue that instead?
- OhMeadhbh - 19795 sekunder sedanFwiw... I now run personal and professional browser profiles from two different jails / cgroups. It's a pain in the arse to set up, and I have to verify my config still works after every update, but I get a good feeling knowing my personal chocolate is not mixing in with my professional peanut butter.
I set up the cgroups hack so I could route traffic from a dev profile into a VPS vpn, and may not be that useful for everyone.
But I think this is a reminder that you may want to have at least two profiles: one public and the other private. Do you really want Microsoft to know you installed the "Otaku Neko StarBlazers Tru-Fen Extendomatic" package to change every picture of a current political figure to an image from the cast of Space Battleship Yamato?
- arafeq - 25192 sekunder sedanthe part about scanning for 509 job search extensions is especially nasty. imagine getting flagged to your employer because linkedin detected you had a job board extension installed.
- stevenicr - 2458 sekunder sedanthis morn while trying to decipher why computer was at 98% memory and 65% cpu
one of the culprits is https://li.protechts.net taking 2GB ram and 8% cpu.
DDG searches say this is something for linkedin. - I had two tabs for linkedin open but left behind as I opened other tabs to research.
So I had not reopened these tabs in over 9 hours and they are still just humming along sucking down almost 10% of cpu and a couple gigs of ram for what?
This is firefox with ublock origin - quick searches saw malwarebytes browser guard considered it (protechts.net) malware for a bit and then took it off the list of things it blocked / warned about.
Not sure this is related to the scan mentioned, but it may be related to the overall concerns about data and unknown usage of resources.
I'm considering blocking this at the dns hosts level at this point.

> Microsoft has 33,000 employees and a $15 billion legal budget
Microsoft has more than 220k employees (it's hard to follow with all the layoffs), and the G&A in which bankrolls legal expenses (but not only - it also contains basically every employee who's not engineering or sales) was only 7B in 2025 - so legal budget is much lower than that.

I ask because it seems like every job I apply to asks for a linkedin profile, and I've heard floating around that if it's not filled in enough most employers assume you're a bot. Heck, one of the forms from the "who's hiring" thread yesterday straight up said if you have < 100 connections they'd throw out your application. So, in order to get my foot in the door, I need to hand over vast and intricate data about my personal life to a third party?
- nticompass - 23793 sekunder sedan> Every time you open LinkedIn in a Chrome[actually Chromium]-based browser
There's a reason I continue to use Firefox (with uBlock Origin) and will never switch.
Also, when I got laid off from a previous job, I made a LinkedIn profile to help find a new job. Once I found a new job, I haven't logged into LinkedIn since - that was almost 2 years ago.

- stevetron - 17025 sekunder sedanI'm certain that if LinkedIn were confronted, that they could produce a response that says they are covered by the TOS you had to agree to in order to use the site. I don't have time to spend scanning legalease. Or make use of LinkedIn. If my system is being scanned, they'll see that I'm using a legitimate licensed copy of Windows 7 on a MODERN computer.

- elwebmaster - 15304 sekunder sedanLinkedIn also violates SPAM regulations on a regular basis. Despite of me having disabled all emails from this service I consistently receive promotional emails. LinkedIn defines a new "type of promotional email" for which it assumes it has implicit consent to send unsolicited emails and proceeds to do so. It then has a fake compliance apparatus by allowing the victim to once again "unsubscribe" from the newly created email subscription which they never consented to on the first place. I really hope there is a class action and these scumbags get fined.

No it isn't. Performing fingerprinting on user's devices, to ultimately profit of financially or worse is misleading. Especially doing this while knowing the user isn't aware what this really means and just deciding it for them.
The headline is just an exaggerated way of saying what is really happening.

Could LinkedIn get something from me there? Potentially, but they're also not really following me around the web. I think given this I'll go install a 3rd browser for linkedin only, or maybe finally just delete my account. It never got me a job and it's a cesspool.

- Imustaskforhelp - 244 sekunder sedanLinkedIn is definitely one of the most by far worse companies I have had to ever interact with.
Literally 2 days ago, I submitted a post: LinkedIn "final decision", restricting my account and making me feel unheard[0] explaining all of some of the worst customer support I have seen
I wish to give a TLDR, but essentially Linkedin will simply reject your account or give you immense headache if your id's aren't being detected by persona (persona is a really shady-company in it of itself with really not the best security practices) I actually lost count of how many times their customer support just responded with a bland message and just didn't even read my message
This is why, being frustrated out of all of this, I actually sent a linkedin customer support message that I don't feel heard, I want to be heard by human, so if you are a human especially when they were asking ME to go to a public notary to sign an affadavite to get a 1 day old restricted Linkedin account (oh btw, its also illegal for a minor to sign an public notary in my country the way they mentioned and I mentioned it about as many times as I could and that I am willing to share my ID like Aadhaar to them but they genuinely don't hear your messages)
Honestly, my experience just says that there is no human customer support in Linkedin, its really a customer support nightmare worse than even some of the telecom horror stories. Perhaps I should contact browsergate.eu if my incident within my country can also be a case of legality or not, essentially I was cooperating with them to give any document that I can reasonably provide but linkedin forms and everything redirect to 404 as well.You can read my experience in depths but my experience really shows me as to Linkedin customer support being so unhelpful that you question how a company can be so bad. I wish for more ethical alternatives to Linkedin and its nightmare to appear within this space.
(I also had a minor idea of asking Linkedin support to see if they read my messages and literally as I told them that I feel unheard, I would like it if they can make me feel heard and that they are reading my messages so If they are actually reading my message, then respond to me with value of 351/13 and I asked the person who joined Linkedin as to why they joined Linkedin, essentially just one line would suffice to know if I am talking to human or not, they did not respond to any of this and essentially, as far as I can tell, pasted another pre-generated response not hearing me)

- chromacity - 19781 sekunder sedanThe real story is what's going on behind the scenes. The charges are relatively flimsy (for the reason I mentioned in my other comment). But here's the cool thing: the site is basically taken from Microsoft's playbook. For years, they pretty transparently bankrolled shadowy, single-issue "grassroots advocacy" groups that went after their competitors under flimsy pretenses. These organizations attacked others but somehow never had an opinion about stuff like Windows Copilot.
This feels very similar, except now it's taking a swing at Microsoft. It's apparently paid for by some mysterious "trade association and advocacy group for commercial LinkedIn users" that runs out of a private PO box in a small German town - uh huh. I'm not going to feel bad for Microsoft, but I would love to read some investigative reporting down the line.
