Understand this story
A Brazilian labor court found that two lawyers deliberately hid prompt injection instructions in a complaint and fined two law firms 10% of the amount in dispute, approximately US$16,000. The case originated from a labor lawsuit at the 3rd Labor Court of Parauapebas in Pará State. When the judge used Galileu, a generative AI tool promoted by the National Council of Justice, to review the complaint, hidden text in white font on a white background was identified, whose content required the AI to respond superficially and not question the document. The court imposed the penalty based on the duties of good faith and non-obstruction of justice under Articles 5 and 77 of the Brazilian Civil Procedure Code. After identifying the content, Galileu issued an alert and automatically blocked processing of the suspicious content.
