A "look-up," a term used to describe search engines that allow the retrieval of stolen data during cyberattacks, has been recently shut down. The Paris prosecutor's office announced on Friday, October 9, 2026, that three 17-year-old teenagers have been arrested. They will be tried in early 2027. The operation, known as LookUp, was a digital tool that allowed users to search for and access data that had been stolen in cyberattacks. This kind of platform is often used by hackers to share and trade sensitive information, such as personal details, login credentials, and financial records. The shutdown of LookUp marks a significant step in the fight against cybercrime, particularly in France, where such activities have been on the rise in recent years. Authorities said that the three teenagers, who are all from the same area of Paris, were responsible for creating and maintaining the platform. They allegedly used LookUp to access and distribute data stolen from various sources, including businesses, government agencies, and individuals. The arrest was the result of an investigation that began after a major data breach affected thousands of users across Europe. The case has drawn attention from cybersecurity experts and law enforcement agencies, who are increasingly focusing on the role of young people in cybercrime. While the teenagers are now facing legal consequences, the incident highlights the growing challenge of combating digital threats in an increasingly connected world.
