Chilean National Extradited to Utah to Face Charges in Large-Scale Credit Card Fraud Scheme
Salt Lake City, UT – A 24-year-old Chilean national has been extradited to the United States and arraigned in federal court in Utah, accused of trafficking in stolen credit card data on a massive scale. Alex Rodrigo Valenzuela Monje, also known online as “VAL4K,” appeared in court on February 26, 2026, following his transfer from Chile the previous day, marking a significant step in a complex, international cybercrime investigation. The case highlights the growing challenges law enforcement faces in combating online fraud originating from overseas and underscores the commitment of U.S. Authorities to pursue such crimes regardless of geographical boundaries.
Valenzuela Monje was initially indicted under seal by a federal grand jury in August 2023, but the path to his extradition was lengthy and involved multiple appeals to the Chilean Supreme Court. The United States formally submitted an extradition request to Chile, which was initially approved on April 22, 2025, according to the Department of Justice. The Justice Department confirmed that Valenzuela Monje was ultimately arrested on the U.S. Extradition request on January 14, 2026, and physically transferred to U.S. Custody on February 25, 2026.
Operating Illegal Online Card Shops Through Telegram
Court documents allege that Valenzuela Monje operated illegal online card shops through the messaging application Telegram from at least May 2021 through August 2023. These shops, known as MacacoCC Collective and Novato Carding, offered stolen payment card data covering virtually all U.S. Payment card brands. Investigators claim he trafficked stolen data for approximately 26,528 cards, including full account numbers, card types, cardholder names, CVV/CVC codes, and expiration dates. Darkweb Informer reported on the scale of the alleged operation, detailing the types of information sold through these channels.
The charges against Valenzuela Monje include trafficking in unauthorized access devices and unlawful transfer of means of identification, offenses that carry significant penalties under U.S. Federal law. Trafficking in unauthorized access devices, such as stolen credit card numbers, is governed by the Access Device Fraud Act, which aims to combat the growing problem of financial fraud facilitated by technology. The unlawful transfer of means of identification refers to the illegal possession and use of personal identifying information for fraudulent purposes.
A Collaborative International Investigation
The extradition and subsequent prosecution of Valenzuela Monje represent a successful collaboration between U.S. And Chilean law enforcement agencies. The investigation was led by the Federal Bureau of Investigation (FBI) in Salt Lake City, with support from Chilean authorities, other U.S. Federal agencies, and international law enforcement liaison offices. Robert Bohls, the Special Agent in Charge of the FBI in Salt Lake City, emphasized that the extradition sends “a clear message” that geographical distance will not shield criminals from facing justice. As reported by Darkweb Informer, this case demonstrates the FBI’s commitment to pursuing cybercriminals operating internationally.
Federal prosecutor Melissa Holyoak echoed this sentiment, stating that the case demonstrates the U.S.’s commitment to prosecuting cybercrimes, even when the perpetrators operate from abroad. This case is particularly noteworthy given the increasing prevalence of cybercrime originating from outside U.S. Borders, and the challenges associated with obtaining extradition and prosecuting offenders in foreign jurisdictions. The successful extradition of Valenzuela Monje sets a precedent for future international cooperation in combating cybercrime.
The Rise of Carding on Telegram
The use of Telegram as a platform for illicit activities, including the sale of stolen credit card data, has been on the rise in recent years. Telegram’s end-to-end encryption and large user base make it an attractive platform for criminals seeking to operate with anonymity. The MacacoCC Collective and Novato Carding channels allegedly run by Valenzuela Monje are just two examples of the numerous illicit marketplaces operating on the platform. Law enforcement agencies worldwide are increasingly focusing on monitoring and disrupting these channels to combat the spread of stolen financial data.
The proliferation of carding channels on Telegram highlights the need for increased cybersecurity awareness among consumers and businesses. Individuals should regularly monitor their credit card statements for unauthorized transactions and take steps to protect their personal information online. Businesses should implement robust security measures to prevent data breaches and protect customer financial information. The FBI offers resources and guidance on protecting against online fraud on its website.
Next Steps in the Legal Process
Valenzuela Monje’s next court appearance is scheduled for May 4, 2026, in Salt Lake City. He has already entered a not-guilty plea to the charges against him. The prosecution will likely present evidence gathered during the investigation, including data recovered from Telegram channels and financial records tracing the flow of funds. The defense will likely challenge the evidence and argue that Valenzuela Monje was not involved in the alleged criminal activity.
The outcome of the case could have significant implications for the prosecution of cybercrime involving international actors. A conviction could send a strong deterrent message to other cybercriminals operating from abroad, while an acquittal could embolden them. The case is being closely watched by law enforcement agencies and cybersecurity experts around the world.
According to booking records from Salt Lake County, Utah, Valenzuela Monje is 24 years old, male, and identifies as White. He is 5’05” tall and weighs 138 pounds, with black hair and brown eyes. He was booked on February 26, 2026, on charges related to federal detainers under an interstate agreement. These details were confirmed by Recently Booked, a public record website.
This case serves as a stark reminder of the evolving landscape of cybercrime and the importance of international cooperation in combating it. As cybercriminals grow more sophisticated and operate across borders, law enforcement agencies must adapt and work together to protect consumers and businesses from financial fraud. The prosecution of Alex Rodrigo Valenzuela Monje represents a significant step in this ongoing effort.
The next court appearance on May 4, 2026, will be a crucial moment in this case. We will continue to follow the proceedings and provide updates as they become available. Share your thoughts on this case and the broader issue of cybercrime in the comments below.
