Potential Security Concern in Dave & Buster’s “Find the Flag” Reno Event

Recently, I came across an issue concerning the ongoing “Find the Flag” promotion at Dave & Buster’s in Reno, which may have inadvertently compromised the fairness of the game.

For those unfamiliar, the event involves uncovering digital flags based on clues provided through their website. It appears that, during participation, some users noticed a vulnerability that allows for early access to future clues. Written in a way that suggests predictability, the URLs for these clues follow a consistent, date-based structure, and the associated files are hosted publicly without sufficient restrictions.

Using basic web development tools, anyone with minimal technical knowledge could:

• Open the developer console while on the official clue webpage,
• Inspect the source code or media files,
• Alter the date parameters in the URL (for example, changing clue-2025-07-16.jpg to clue-2025-07-17.jpg),
• Instantly reveal upcoming clues ahead of their scheduled release.

This loophole likely explains how certain participants were able to find multiple flags within minutes of their release, raising concerns about the integrity of the game. Conversely, finding a flag through legitimate means required careful problem-solving and genuine effort.

In response, I’ve reported this observation directly to Dave & Buster’s Guest Relations team, including technical details and screenshots. I’m choosing to refrain from publicly identifying individuals or making accusations, as I believe the company should be given the opportunity to address and resolve the issue appropriately.

This situation raises important questions about the security measures in place for promotional events like “Find the Flag.” Transparency and robust protection are essential to ensure fair competition and preserve the fun for all participants.

Stay tuned for updates, and always approach online challenges with awareness of potential vulnerabilities.
