Federal Police Investigation Reveals Fraud in CNU Involving Family Gang, Sale of Answer Keys and Values Exceeding R$ 400 Thousand per Position in Federal Public Competitions
A Federal Police operation revealed a scheme of fraud in CNU (Unified National Contest) that involved the sale of answer keys and the participation of a gang with family ties. The most recent case exposed a woman who allegedly paid R$ 400 thousand to secure a position as a tax auditor, one of the most coveted roles in the competition.
According to investigations, the candidate worked as a prison officer in São Paulo, and the amount was raised by her own family, who even sold personal assets to make the payment. The scheme, identified from identical evidence among candidates, indicates an organized structure of corruption and leak of confidential information within a contest that had been presented by the federal government as the “Enem of competitions.”
Fraud Scheme in CNU and Gang Activity
Investigations show that the gang responsible for the fraud in CNU was led by a former police officer, the candidate’s uncle.

The group, already known to authorities, had a history of crimes that included previous frauds, corruption, and even homicide.
The PF is investigating how the individuals obtained early access to the official answer keys, which were allegedly distributed to clients for high payments.
According to the inquiry, the criminals provided the exam content in advance to candidates who paid amounts ranging from R$ 300 thousand to R$ 500 thousand, depending on the desired position.
The evidence shows that at least ten identical answer keys were identified in exams administered in the city of Patos, Pernambuco, which made the pattern of answers statistically impossible to occur by coincidence.
Operating Method: Answer Keys, Professors, and Scheme “Clients”
The group’s operation followed a sophisticated logic.
The criminals employed “specialist teachers” contracted to quickly solve the questions from the illegally obtained exams.
Afterward, the answer keys were passed on to a limited number of candidates.
In specific cases, gang members posed as candidates to fill in the answer keys in exam rooms.
This model had been observed in other public competition frauds and required an efficient structure of communication and logistics to escape oversight.
The CNU, due to its national reach, ended up becoming a high-value target for this type of organized crime.
The Candidate’s Profile and Unusual Details of the Investigation
The woman caught by the PF aimed to secure a position as a labor tax auditor, a role with an initial salary of R$ 22 thousand per month.
According to investigations, after obtaining the fraudulent answer key, she enrolled in a training course in Brasília, where she began exchanging messages with her own father — also a public servant — to negotiate anabolics.
The case drew attention due to the mix of unusual elements: the candidate had not even read the full notice and was shocked to discover new steps in the process.
To prevent her from being eliminated, the gang even provided a 600-page study guide to assist her in the training exams.
Intercepted messages by the PF show a careless behavior and excessive confidence in the protection offered by the criminal group.
Context of CNU and Institutional Impact of the Fraud
Created by the federal government to centralize federal public competitions, the CNU was announced as a policy for modernization and efficiency in accessing public service.
The idea was to allow candidates to compete for various careers in different agencies in a single process.
However, the fraud case discovered by the Federal Police undermines the credibility of the unified model.
The investigation is still ongoing, but involved authorities acknowledge that the episode could compromise public trust in the system, especially after the large national mobilization for conducting tests in multiple cities.
Recurring Frauds and the Risk of New Manipulations
Although the current investigation refers to the first phase of CNU 2024, there are fears that other criminal groups may have attempted to replicate the same method in new editions.
The PF keeps part of the information confidential to avoid jeopardizing ongoing operations but has already confirmed the involvement of civil police officers and public servants in supporting the scheme.
Investigators emphasize that the complexity of the fraud will require security changes in upcoming tests, including stricter control of access to materials and electronic monitoring of examination boards.
If there is not a prompt response, the CNU may face the same historical challenge as other national contests: public discredit and mass litigation over the results.
