Proof of Concept Exploit
Noun · Security & Infosec
Definitions
A demonstration exploit built to show that a vulnerability can be triggered or weaponized, often without being fully polished for stealth or large-scale use. Proof-of-concept exploits help defenders validate severity, but once public they can also accelerate opportunistic attacks.
In plain English: A demonstration exploit that proves a vulnerability can really be used.
Example: "The vendor advisory became urgent after a proof of concept exploit appeared online and multiple copycat scanners started hitting exposed systems."
