Qilin takes responsibility for major Argentinian football club hack

Club Atltico River Plate, which is the largest professional football and sports club in Argentina, had its systems and data claimed to be compromised by the Qilin ransomware operation, Cybernews reports.

Qilin only provided an Onion share link redirecting to thousands of files between 2021 and 2025, most of which are in PDF, Excel, Word, image, email, and compressed archive formats. Analysis of the exposed CARP index revealed invoices, purchase requests, budgets, credit notes, contracts, technical specifications, photographic records, and architectural plans. CARP has yet to acknowledge the breach.

Such a development comes as Russia-linked Qilin was noted by Cybernews' RansomLooker tool as the most prolific ransomware gang, laying claim to 627 intrusions this year, with the Church of Scientology, International Game Technology, Cornerstone Staffing Solutions, and Spark Power being its most recent victims. Most Qilin attacks have been aimed at the U.S., followed by France, Canada, South Korea, and Spain, according to data from Comparitec.
