Macnica Launches ANTERAS DarkWeb Amid Rising Ransomware Cases in Japan

On September 8, 2026, Macnica launched the ANTERAS DarkWeb service to identify leaked information linked to known and unidentified external assets. This initiative comes as Japan reports 1,021 ransomware cases over the past five years, highlighting the growing threat of credential misuse. The service integrates with Macnica's ANTERAS ASM platform, focusing on preventing ransomware attacks by analyzing leaked data from public-facing assets. The service aims to assist companies in prioritizing responses based on the type and cause of leaks. Notably, over 40% of intrusion routes involved devices that had received security patches, indicating attackers are exploiting legitimate credentials. The service is designed to help organizations manage risks associated with leaked information, particularly from overseas branches and group companies. Macnica emphasizes the importance of addressing the misuse of leaked credentials to mitigate ransomware threats.

Key Points: • Macnica launched ANTERAS DarkWeb to combat rising ransomware incidents in Japan. • The service targets both known and unidentified assets to prevent credential misuse. • Over 40% of ransomware attack entry points involved patched devices, highlighting a critical security gap.
