The online currency used by Microsoft's Xbox360 console is MS Point. Recently, someone found a loophole - just by changing the numerical value in the URL, you could obtain an MS Point redemption code. The forum where this loophole was posted even became temporarily inaccessible due to excessive traffic!
However, as a major international corporation, Microsoft naturally immediately blocked the loophole. But this loophole has already cost Microsoft 1.2 million USD.
Even elementary school students know that stealing from others is wrong, but Microsoft also needs to take some responsibility. Hopefully, they will learn from this incident.
