In a high-profile case that has captured global attention, a Chilean national has been extradited to the United States for allegedly operating a major credit card data trafficking scheme. Alex Rodrigo Valenzuela Monje, who goes by the moniker “VAL4K,” was brought from Chile to the U.S. on February 25, 2026. He has been formally charged in federal court in Salt Lake City with serious offenses related to the sale of compromised credit card information and the illegal transfer of identification information aimed at facilitating criminal activities.
The Scope of the Trafficking Operation
Charges against Valenzuela Monje allege that he ran an illicit online shop where he sold unauthorized access devices, commonly referred to in cybercrime as “dumps.” This operation reportedly occurred between May 2021 and August 2023, primarily using Telegram as the platform for transactions.
Telegram Channels and Stolen Data Figures
Documentation from investigators reveals that Valenzuela Monje was the operator behind Telegram channels named MacacoCC Collective and Novato Carding. These channels were discovered to be distributing sensitive payment card details linked to thousands of U.S. consumers. The indictment specifies that the operation trafficked data related to approximately 26,528 cards from just one credit card brand alone.
The information sold by Valenzuela Monje included sensitive elements such as card numbers, cardholder names, expiration dates, and CVV codes. Such details can facilitate fraudulent transactions and identity theft, increasing the risk for consumers.
Encryption and Evasion in Cybercrime
The choice to operate via Telegram underscores an emerging trend in carding cybercrime, where individuals use encrypted messaging platforms to avoid detection. This operational model is becoming increasingly common within dark web ecosystems, allowing cybercriminals to connect with a global client base without needing conventional website infrastructure.
Extradition Process and International Cooperation
The extradition of Valenzuela Monje was initiated following a sealed indictment issued by a federal grand jury in 2023. The U.S. government’s formal extradition request was approved by the Chilean Supreme Court in April 2025. After several legal appeals, he was apprehended in January 2026 and subsequently transferred to American authorities.
Collaborative Efforts in Law Enforcement
The investigation was spearheaded by the Federal Bureau of Investigation (FBI), with significant contributions from international partners. This case exemplifies how nations are increasingly working together to combat international cybercrime. U.S. Attorney Melissa Holyoak emphasized the collaborative spirit of law enforcement, stating, “Individuals may believe they can hide behind foreign borders, but the United States is committed to investigating and prosecuting these cybercrimes targeting Americans.”
FBI Special Agent in Charge Robert Bohls also commented on the broader implications of this extradition, noting that geography should not shield cybercriminals from accountability. “Those who exploit technology to victimize American companies and citizens will be identified, located, and brought to justice,” he affirmed.
The Bigger Picture of Cybercrime
This stolen credit card data trafficking case highlights an alarming reality within the landscape of cybersecurity—digital financial crime has become a global issue. The proliferation of messaging apps, the use of cryptocurrency for payments, and the availability of automated data distribution tools have made it easier for cybercriminals to operate across borders.
While actions taken by law enforcement, like the extradition of Valenzuela Monje, represent progress, the ongoing existence of carding marketplaces suggests that strict enforcement might not be sufficient on its own. Financial institutions, technology platforms, and consumers need to collaborate in strengthening fraud detection and identity verification measures to counteract the persistent value of stolen data.
Next Steps in the Legal Proceedings
As of now, Valenzuela Monje has pleaded not guilty to the charges. The case is set to advance through the U.S. judicial system. Continuous investigations into this matter emphasize that stolen credit card data trafficking remains a flourishing and serious form of cybercrime in today’s digital economy.
