In plain words
Think of a VPN like a special kind of door that helps keep your internet connection private and safe. But if someone finds a weakness in that door, they can get in and take sensitive information. That is what happened here.
What's broken
The specific bug is not detailed in the source, but it is a vulnerability¹ in a VPN product that was exploited by hackers to steal personal information of roughly 240,000 people. An attacker could use this to get access to private data.
How it actually works
Here's how it actually works: hackers found a weakness in the VPN product, which is like finding a key² to a locked door. Once they had the key, they could get in and take the information they wanted. The VPN is supposed to protect the connection, but the vulnerability allowed them to bypass that protection.
Proof of concept
It is not clear from the source if there is a public proof-of-concept³, but the fact that 240,000 people were affected shows that the flaw is real and was used by hackers. A proof-of-concept would demonstrate that the vulnerability is not just theoretical, but actually exploitable.
Is it real
The breach has happened and 240,000 people were affected, which means it is real and the vulnerability was actively exploited. There is no information on limiting factors, but the fact that it happened shows the importance of fixing such vulnerabilities.
What to do
To fix this kind of issue, the company would need to update or patch⁴ the VPN product to close the vulnerability. Users might also need to change their passwords or take other security measures to protect themselves.
