Speedrunners are vulnerability researchers, they just don't know it yet
Discussion
Video game speedrunners who discover glitches and exploit game mechanics are unknowingly practicing skills similar to cybersecurity vulnerability researchers. Their expertise in reverse engineering games, analyzing code, and finding exploits could translate well into professional cybersecurity careers.
Speedrunning vs vulnerability research
Key difference is speedrunning being more collaborative/open vs legal constraints in vuln research. Most speedrunners replicate known exploits rather than discover new ones. Bug bounty space is competitive due to money.
Documentation and history
Speedrunning community struggles with poor documentation practices, using Discord/Google Docs without proper versioning. Historical knowledge gets lost, as shown by rediscovery of old tricks like "Devil's Spell".
Game versions and bugs
Speedrunners often use specific old game versions to exploit known bugs. Different regional releases or console versions may have unique glitches. Players discover hundreds of bugs that casual players never encounter.
