TWU Local 100: Qilin Ransomware Targets TWU Local 100

Qilin Ransomware Group Targets TWU Local 100 in Latest Cyberattack

On February 23, 2026, the ransomware group Qilin claimed responsibility for a cyberattack against TWU Local 100 (twulocal100.org), a prominent U.S.-based membership organization. The threat actors issued a warning that sensitive data obtained during the breach would be leaked unless their demands were met within a specified timeframe.

Qilin, known for its aggressive extortion tactics, has increasingly targeted organizations across sectors, leveraging stolen credentials and vulnerabilities to gain access. The group’s statement underscores the growing risk of data exposure in ransomware incidents, where attackers not only encrypt systems but also exfiltrate information to pressure victims into compliance.

The attack highlights the persistent threat posed by ransomware groups to critical infrastructure and membership-based entities. Details on the extent of the breach, the nature of the compromised data, and TWU Local 100’s response remain undisclosed. Further developments may clarify the impact on the organization and its members.
