Hey there! Im working on an online gaming security and something that really concerns me is how to prevent fraud or any harm to my gains, anyone nows how do users could exploit the application in order to withdraw more than they should, bypass limits or something alike?. How will a black hat try and steal money from the app???
First thing, check all your bonuses for math. Most casinos get hit by bonus hunters before anything else. If your bonus mechanics have even a small edge for the player, they will find it and abuse it at scale.
Second, sometimes players show up and start winning suspiciously often on specific games, usually slots. You need to log every bet and every action on your platform so you can actually analyze what happened. Also set up session recording so you can watch what the player was doing. Pay extra attention to new game studios, that's where you'll often find vulnerabilities where rtp can be manipulated.
If you're running an affiliate program, expect fraud traffic. You need to collect everything on players, fingerprints, wallet addresses used for deposits, device data, all of it. That's how you catch fraud rings.
For the site itself, set up a waf, that covers a good chunk of attacks. Cloudflare for ddos protection. Basic stuff but a lot of operators skip it.
And one thing to always keep in mind: any system can be broken. Your job isn't to make it impossible, it's to make the attack expensive enough that it's not worth it.
