Nefarious game makers appear to be leveraging a chat-based Roblox exploit that results in automatic account bans for unsuspecting users.

Roblox ultimately discovered that someone had hacked a single server of the game, allowing them to circumvent the rules and upload code that clearly violated the company's rules.

“We thought our new 'Hack-A-Cat' game was a unique opportunity to inspire interest in cybersecurity for a younger audience using Roblox,” said Stu Sjouwerman, CEO of KnowBe4.
