Car Salesman Hijacks Dealership Computers Until IT Admin Delivers Company-Wide Lockdown Revenge

in Social Issues

A slick-talking Cadillac salesman crowned himself the showroom’s secret tech king, slipping in USB drives loaded with forbidden tools, snatching permanent admin rights, and turning a shared desk into his private fortress. Everyone else fumed while the real sysadmin begged management for help and got nothing but shrugs and “handle your own mess” replies.

Finally pushed to the brink, the overlooked IT pro snapped. With zero backup from the top brass, he quietly built an iron-clad digital cage, rolled it out overnight, and watched the self-proclaimed computer genius crumble when his tricks suddenly stopped working. The entire sales floor felt the squeeze and the culprit wandered around useless.

IT pro locks down dealership PCs after management refuses to stop a rule-breaking salesman.

Not the actual photo.

'Leveraging My Job Description To Put An End User In His Place?'

I used to manage a Cadillac dealership's network a couple of years ago.

There was a car salesman who also liked to study computers on his spare time.

Unfortunately that also meant that he knew way too much to be absolutely dangerous.

I would constantly get complaints about him bunking down on a specific floating desk on the floor and locking it out from anyone to use it but him.

I reached out to management about it, but they didn't want to do anything about it.

 

Even though he was bypassing many security features

like local admin (used a boot env to give himself local admin), web filtering, unapproved apps, remoting, etc (all via a USB with a bunch of portable apps)

Management: "Why are you coming to us about an IT problem?"

"This isn't a management problem when it involves computers."

"Isn't that your job? I'm pretty sure that's in your job description."

You get the idea. But I was sick and tired of getting calls and messages daily about this one guy.

So I decided that if management wasn't going to have my back on this issue, then I guess I have free reign to handle it how I please, right?

Since I was dealing with an above average user, I decided to go to the furthest extreme.

I took a machine, imaged it to the same image as the floating desk machines, and went to town planning all the restrictions needed.

BIOS locked with password. Boot to USB disabled. Chassis locked and closed (no cmos reset). Auto Login to a generic "sales" account.

USB disabled in windows. Desktop redirected to a folder on the file server with locked permissions (no delete. specific icons only).

Chrome browser only no IE or anything else. Chrome bookmarks set to only what is needed.

Log off removed; only restart or shutdown (Even if he did managed to somehow log off, it would just log back in to "sales").

And a litany of other basic windows restrictions that essentially silos the machine to either chrome or their Car sales software.

I brought all my changes and my purchase requisition for the locks over to management and was approved with no questions.

I sold it as a necessary security measure and threw my weight around about how "This is in my job description to address it and implement it."

Spent an early Monday morning rolling out all the changes before he came in. Late afternoon rolls around and he finally shows up.

I'm off the clock, but decided to stay to see the fallout. He walks in, makes a bee line to his "desk" and watched as he sat confused at everything.

"I can't log out. I can't boot my USB? Windows can't see my USB either. I can't do anything at all!"

I watched in pure satisfaction as he just got up from the chair and walked around the sales floor aimlessly with nothing to do.

The bonus part is after all the changes, whenever a different sales person complained about the changes,

all I needed to say was "Sorry for the inconvenience! The changes were necessary due to a salesperson messing with the computers.

I'm not allowed to say who it was though. So unfortunately the changes will need to stay."

They all knew who it was though. EDIT: Thanks for the awards!!! I appreciate it!!

At the heart of the story, our OP wasn’t dealing with a clueless grandma clicking phishing links; he was up against a self-taught salesman who knew just enough to be a walking security violation. Management’s response “That’s an IT problem” basically gave him a blank check to go full fortress mode.

On one side, you’ve got the salesman who probably felt like he was just “optimized” his workflow. On the other, you’ve got literally every other salesperson who couldn’t use the shared desk, plus a sysadmin whose phone wouldn’t stop blowing up.

When leadership shrugs and says “not my circus, not my monkeys,” the ringmaster has to take drastic measures, or watch the circus burn.

This story is a textbook example of why organizations lock everything down in the first place. Verizon’s 2024 Data Breach Investigations Report found that the human element – such as errors, privilege misuse, and social engineering – plays a role in 68% of breaches, with stolen credentials involved in 49% of cases.

One overconfident user with a USB stick can become the human element that costs millions. In a 2019 CSO Online article, security expert Roger Grimes warned: “Overly permissive permissions may or may not be the fourth biggest cybersecurity risk, but given the headlines about permissions mistakes exposing huge amounts of data, it sure seems to be the case.”

He was discussing the dangers of incorrect access controls in general, but he might as well have been narrating this dealership drama. The salesman wasn’t malicious (probably), but his “a little knowledge is dangerous” attitude created exactly the kind of risk Grimes warns about. The sysadmin’s nuclear lockdown wasn’t personal; it was survival.

Healthy workplaces draw clear lines: IT sets technical policy, management enforces behavioral policy. When those lines blur, everyone suffers, except the one guy with the USB, until someone finally yeets that USB into the sun (metaphorically).

The real fix? Leadership training that treats security policy like any other company rule, because “it’s just computers” is how ransomware brunch gets served.

Here’s the input from the Reddit crowd:

Some people say the salesman’s actions were a clear security violation and management dropped the ball by not enforcing policy.

[Reddit User] − "This isn't a management problem when it involves computers." I respectfully disagree with your managers.

IT's job is to ensure the business has a functioning tool to use to make their job easier while ensuring those tools are kept secure against outside threats.

The user was bypassing security protocols and securing the workstation so only he could use it. I HAVE to think that's a violation of the AUP.

That directly falls into management's lap. It's not a failure of IT, it's abuse by the user.

dergbold4076 − Sounds like the computers should have been locked down a while ago

digitydigitydoo − I love how many managers decide their job description only includes “managing personnel” when it’s convenient for them.

Inside-Finish-2128 − Every textbook I’ve read about security has always led with some statement

that security will only go as far as management wishes to let it. If the brass decide security is getting in their way, they’ll whack it.

Some people explain that overly strict restrictions exist because of users exactly like this salesman.

Charlie_Mouse − Spot on. When people wonder why company machines, USB drives etc. are locked down so hard, software restricted etc. there’s usually a user like this at the back...

Where I work we’re quite happy to open things up for devs and others who know what they’re doing (and actually have a business related reason for it)

but they know if they take the p__s or introduce malware onto the network that access is going to be taken away.

_slash_s − users that don't enough to actually fix anything, but know enough to really f__k s__t up, are the worst.

EatMoreArtichokes − Very nice! Now I guess he has to actually try to sell cars or something right?

Some people share their own horror stories of clueless or rogue users breaking everything.

t3m3r1t4 − I remember I had an employee who decided they could watch all the illegal streaming content while they worked from sites like Project Free TV.

Sure she THOUGHT she was productive but seeing as how we worked for our NATIONAL BROADCASTER I felt it was in poor taste

and also meant they weren't actually productive because they were watching TV.

Charlie_Mouse − Best “a little knowledge is a dangerous thing” meets Sales guy story: at a previous job we had a few small remote branch offices.

One sales guy decided he wanted to hook his laptop into the network at a table that had a network point that wasn’t patched in… The next several hours were...

And yes, we made sure branch server & network cabinets were locked after this.

Some people are simply satisfied that the rogue user finally got what was coming to him.

Nimaafshari54 − This story makes my inner network admin smile

maydayvoter11 − sounds almost like he was running Tails or another OS off a USB stick.

I'm struggling to imagine why he would need to do that for anything work-related at work.

At the end of the day, one IT pro turned “not my job” into “watch me make it my job” and delivered karma so cold it needed a jacket. Do you think the full-sales-floor lockdown was genius justice, or did it punish the innocent along with the guilty? Would you have gone nuclear, or tried one more polite email to management? Drop your verdict in the comments!
