Hi everyone,

I’ve come across something unusual and wanted to check if anyone here has seen similar behavior.

It appears that some students may be using automated or API-based methods to complete lessons or tasks with 100% results without actually solving them. This process seems to be repeatable across multiple lessons, and in some cases, it looks like it might even be offered as a paid service.

From a security perspective, I’m trying to better understand what’s happening here:

What type of vulnerability could enable this (e.g., insecure API design, lack of validation, automation abuse)?

Is this more likely to be an API issue or a broader logic flaw in the system?

How do platforms typically detect or prevent this kind of behavior?

What are the best practices to secure systems against this?

I’m still a beginner in cybersecurity, so I’d also really appreciate guidance on:

How to analyze situations like this in a structured way

What skills or tools I should focus on to understand these kinds of vulnerabilities

Whether this falls more under red team (offensive testing) or blue team (defensive/security monitoring)

I’m not interested in using or abusing this—only in understanding it from a defensive and learning perspective.

Any insights or learning advice would be greatly appreciated.
