KIS MailMo Webinar Introduces Lower-Cost Email Training and Suspicious Email Management as AI Makes Targeted and CEO Fraud Emails More Sophisticated

In recent years, emails related to targeted attacks and business email compromise, commonly known as CEO fraud, have increased, and the resulting damage has expanded. In the Information-technology Promotion Agency’s “Top 10 Information Security Threats 2025 [Organizations],” targeted attacks aimed at confidential information ranked fourth, while business email compromise ranked ninth. Cyberattacks that begin with email have become a major issue for business continuity. With the spread of generative AI, emails written in unnatural Japanese are becoming less common, making it possible for anyone to create messages that look more authentic. Requests impersonating real business partners or executives, payment instructions disguised as routine business communications, and instructions to take out information are all becoming harder to detect. Many companies conduct targeted email training every year in response to this situation. However, preparation, delivery, aggregation, reporting, and other tasks place a heavy operational burden on IT departments and tend to increase costs. As a result, training itself can become the goal and lose practical effectiveness. Companies also face challenges in tracking and managing responses when employees report suspicious emails. Many companies and organizations use employee email training as a countermeasure against targeted attack emails. While effective for raising awareness and improving employees’ ability to identify suspicious emails, it creates significant cost and operational burdens for the people in charge. Pre-training preparation, post-training checks, exclusion settings based on the email environment, scenario creation for increasingly sophisticated attacks, and aggregation of delivery and click data all require substantial effort. In addition, some services do not allow flexible customization by target group or make it difficult to confirm training results. Advanced training and increased delivery volumes can also generate additional costs. These barriers in cost, workload, and customization are major factors preventing continuous email training. This seminar introduces KIS MailMo, a targeted attack email training service, as a way to reduce costs, ease the burden on training administrators, and improve employees’ security awareness. KIS MailMo was adopted by 150 companies in the three months from January to March 2026, and by a cumulative total of 750 companies since its release in October 2022. It offers more than 300 editable training scenarios and enables continuous attack email training aligned with the latest attack techniques. A new feature also strengthens suspicious email reporting and management, helping organizations receive employee reports, track response status, and streamline operational workflows. The presentation will include demonstrations of the training operation flow enabled by KIS MailMo and its suspicious email reporting and management functions. The seminar is intended for companies and organizations that want to lower email training costs, reduce operational workload for training administrators, or improve suspicious email response handling.
