Lawyers Hid a Secret Message to Brainwash the Court's Robot Judge, Got Fined for Their Trouble
Ourtake
Turns out the robot read the fine print, and the lawyers were the ones who got caught in white font.
What happened
A Brazilian labor court fined two law firms 10% of a R$842,000 claim after finding they hid a prompt-injection command in white-on-white text in a filing. The command was meant to make the court's Galileu AI review tool give a superficial response. The system flagged the text, issued an alert and blocked processing of the suspicious content.
