The Qilin ransomware operation sustained a leak-site surge in second half of 2025, publishing more than 40 victim listings per month and keeping pressure on victims. It used a double-extortion model, encrypting data and threatening to leak stolen information to coerce payment.

The pace and breadth of postings indicate a mature ransomware operation with continuing global reach.
