Code Review Challenges
Developers review real vulnerable code, identify the security flaw, and select the correct fix from multiple options. A two-phase flow that builds both detection and remediation skills.
Two phases. One challenge.
Find the vulnerable block
Developer is shown a real-world code snippet with one or more vulnerable lines. They click the block they believe contains the security flaw. No multiple choice — they have to read the code and reason about what's wrong.
- ✓ Production-realistic code patterns
- ✓ Click-to-select on the actual code line
- ✓ Multiple attempts allowed
Choose the correct fix
Once the vulnerable block is identified, the developer picks the right fix from a set of plausible alternatives. Distractor options include common-but-wrong fixes — the kind that pass code review and still leave the bug in production.
- ✓ Multiple-choice fix selection
- ✓ Plausible-wrong distractors
- ✓ Explanation revealed after answer
A challenge, mid-flow.
Tuned for learning, not gatekeeping.
Hints without penalty
Developers can request a hint at any point. Hints don't reduce the final score — the goal is comprehension, not punishment.
Attempt-based scoring
Score is calculated from the number of attempts taken in each phase. Fewer attempts = higher score. First-try success on both phases earns the maximum.
Explanation after every answer
Once the fix is selected — right or wrong — the platform shows why each option is safe or unsafe. Distractors aren't just labelled wrong; the failure mode is explained.
Reading vulnerable code is the actual job.
Most developer security training asks engineers to watch a video about SQL injection and answer a multiple-choice quiz. Code Review Challenges flip that: they put the developer in front of code first, and force the same kind of reasoning a code review demands. Detection and fix are scored separately because in real reviews, knowing something is wrong and knowing how to fix it are two different skills — and engineers can be strong at one without the other.
