TF2 Fake Lag in Pubs?

[lewdicrous]

Recently, I was playing on a Degroot Keep server and I came across a spy with over 60 pts. He was a good 2 Meters ahead of me when I saw his arm go down and somehow kill me. I investigated a little more and realized his ping was around 900 and he was teleporting around a lot. One of the players suspected he was using a lag script or interp abuse. Can someone explain this?

lag compensation is partly client-sided, and sadly that part is the one that decideds whats a hit.

its been a week since the post. Iv'e already seen 3 other lag spies with 800 ping, getting topscorer by a mile.

Edit: 4 spies

It's probably cl_interp 5

spy hitreg is ♥♥♥♥♥♥ because it's lag compensated instant hitscan that uses player view angles to determine backstabs
by being laggy as ♥♥♥♥ and not having fast-updating enemy player positions, you can move behind the 90 degree view point before your client gets the info that they've moved/turned, and your stab will register because the server allows generous amounts of lagcomp rewind to determine hits
same principle that trickstabs work on only made more extreme, all you need to know is to turn the direction you just came from since that's where they'll be looking

valve is being really slow to patch the interp abuse and likely won't ever rework backstab mechanics that break when latency gets involved
they could try limiting max lagcomp time to like 150ms or something on casual, idunno

its a hack. 800+ ping, cl_interp 5 and autostab all at once

it's not a hack, it's a console command.

First off, don't necro.
Second off, it's not even a hack.
Third off, he just said it's a console command. He knows more than you.

nice necro

[lebron's veiny ahhh D]

usually as for now, this is a cheat called backtracking, you could research more on how it works but it works as described, stabbing away from miles, the high ping is just an excuse to blame his stabs

It’s possible was the Larp hack because what it does it teleport the person using the hack closer to someone and getting the kill but it’s easy to spot because every time they teleport they lag but so far looks like it only scout and spy cheaters that use it still kick them if you see those guys.
Here’s a video of Maxbox of his spot the hacker series recently that he got sended from someone finding someone using the hack:
