A major Roblox hack has returned in a new form, causing innocent players to face bans as they enter and play games designed to trigger an exploit within the platform.

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

It looks like on the four year anniversary of the John Doe Roblox rumour, people are questioning if John Doe is real and if he'll be hacking your account on March 18.

“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.
