Tokyo FM Broadcasting Hit by Alleged Cyberattack, 3 Million Records Potentially Exposed Tokyo FM Broadcasting Co., one of Japan’s leading radio stations, is at the center of a suspected cybersecurity breach after a threat actor using the alias “victim” claimed to have infiltrated its systems on January 1, 2026. The attack occurred during the New Year holiday, a period when many organizations operate with reduced staffing. The hackers assert they exfiltrated over 3 million records, including sensitive personal and technical data. Among the compromised information are full names, birthdates, email addresses, IP addresses, user agents (device/browser details), internal login IDs, and employment-related data. A screenshot shared by the threat actor on X (formerly Twitter) under the handle H4ckmanac appears to support the claim, though cybersecurity experts are still verifying the authenticity of the stolen data. Tokyo FM has not yet confirmed the breach, and the incident remains under investigation. If verified, the exposure of such a large volume of personal and operational data could pose significant risks, including potential phishing attacks, credential misuse, and further exploitation of internal systems. The situation is ongoing.
