Upcoming Free Workshop on Microsoft Vulnerabilities

On June 13, 2026, ISFNet's specialists will participate in a free seminar organized by Heatwave Co. at their practical security school, SecuJuku. The seminar, titled "Learn About the Latest Vulnerabilities!! MS Monthly Vulnerability Study Session," aims to equip infrastructure engineers and security personnel with crucial knowledge essential to combat increasingly sophisticated cyber threats.

As cyberattacks become more advanced year by year, building knowledge in IT infrastructure security is vital. This session will feature ISFNet experts explaining how to accurately identify vulnerabilities that are truly important in the field.

Workshop Agenda (Tentative)

1. Updates after last month's vulnerability disclosures: After the patch release, updates related to last month's vulnerabilities will be explained.
2. Overview of vulnerabilities: The number of vulnerabilities for which security patches have been offered will be outlined along with details about any zero-day vulnerabilities.
3. Exploited vulnerabilities: Discussion on zero-day vulnerabilities that have been confirmed as exploited at the time of security patch release.
4. Publicly disclosed vulnerabilities without known exploitation: Vulnerabilities publicly detailed but not yet exploited will be explained.
5. Other critical vulnerabilities: An overview of vulnerabilities graded as "Critical" by Microsoft, along with those requiring attention that may not be categorized as such.
6. Other precautions: Known issues related to applying the security patch will be explained at the time of the patch's release.

Note: All details, including schedule and content, are subject to change.

Speaker's Comment: "By attending this session, you can become an expert in Microsoft's handling of vulnerabilities! Only vulnerabilities listed as 'Urgent' by Microsoft do not require immediate attention; it’s critical to consider factors like PoC presence and CVSS vector values to assess vulnerabilities needing your organization's response."

Previous Session Recap

The last seminar held on May 16, 2026, was attended by a total of 99 participants, comprising 15 in-person and 84 online attendees, receiving overwhelmingly positive feedback. The opportunity for direct questioning with the presenters enhanced the value of in-person participation, which we highly encourage.
