In pre-COVID-19 days, IT handling that kind of request would have required it to come in face-to-face. But since everyone's working from home, that's intractable.
The failure point here is that IT should have confirmed via an independent secondary channel the identity of the requester, but it appears they either got lazy or their protocols assumed Slack could not be compromised in this way so the request was already authentic.
In pre covid times it wasn't uncommon for people in my office (which didn't have a dedicated onsite IT person) to ping IT on slack for the person sitting next to them to ask for a PW reset.
Face to face doesn't solve anything. If there's a 2000 person company and you can get into the building, chances are you could walk up to the IT desk and say "hey my name is John Doe I'm an engineer here and I locked myself out of X, can I get a reset?" And you'd be given it without any verification
And in all but the smallest companies I've worked for, you needed a card swipe at the door (or an escort) to pass from public to internal areas.
This is just really, really basic physical security stuff.

And once you're past the barrier of those internal areas, you're unlikely to be questioned in all but the most strictly controlled places.
I did it accidentally once at a big hedge fund sort of company. I thought I was being escorted by my friend’s friend. But it was actually just some one familiar with them/their names not fully understanding what I was saying letting me thru the ~3? Times a badge scan was required. I wasn’t paying attention. Only when my friend got scared he would get in trouble did I realize what had happened.
Plus that's still vulnerable to googling photos of the employee you're impersonating and photoshopping a piece of paper with the date.
Most employees have a photo badge, so they could scan that and look up your records in the HR database. If you've lost your badge, they could ask your name and look that up in the HR database, which hopefully has a photo on file.
It’s not foolproof, but it’s incredibly difficult to prevent tailgating because people don’t want to start an incident by incorrectly challenging a coworker. I’ve heard of it somehow happening even with card turnstiles, double door scans and required photo confirm by lobby security.
