Are You Aware of Authentication Credentials Leaked on the Dark Web? Webinar for CISOs and IT Security Leaders

How to Check Your Employees' Password Leakage Status and Ensure Safety We are offering, exclusively to seminar participants, a free service to check the number of leaked passwords associated with your organization. Using your company email domain as a keyword, we will search for any publicly exposed or leaked authentication information on the dark web. The investigation is conducted entirely on external, highly confidential internet spaces such as the dark web, with no access to your internal corporate network. We only assess external exposure status.

Regulatory Requests from the Financial Services Agency and the Bank of Japan Regarding Frontier AI The risk of authentication data breaches is becoming increasingly severe due to advancements in AI. In April 2026, Anthropic Corporation announced its frontier AI model 'Mythos,' capable of autonomously and rapidly identifying vulnerabilities and generating attack code—sending shockwaves globally. In response, in May 2026, the Financial Services Agency (FSA), jointly with the Bank of Japan, issued a request titled 'Short-Term Measures for Financial Institutions in Light of Threats Posed by Frontier AI.' Given that advanced general-purpose AI (frontier AI) can accelerate vulnerability discovery and attack code generation—drastically shortening the window between discovery and exploitation—the request urges financial institutions to strengthen asset management, vulnerability management, patching, monitoring, and resilience under direct executive oversight, aiming for implementation within approximately one month. The Japanese Bankers Association has also issued reference guidelines on cybersecurity management frameworks to its members based on this request.

The structural challenges highlighted by this directive are not limited to financial institutions but are common across all industries. As attack speeds increase, already leaked authentication credentials become a 'shortcut' for attackers—eliminating the need to exploit vulnerabilities—and serve as a common starting point for breaches. Annual audits or post-incident responses alone cannot keep pace with these changes. It is now more critical than ever to proactively visualize your organization’s exposure and leakage status from the attacker’s perspective and take preemptive action.

No Internal Anomalies—But Your Company’s Data Might Be Circulating on the Dark Web Many companies invest in securing internal networks and endpoints but fail to continuously monitor company-related information circulating on the dark web.

For example: - Former employees’ or third-party vendors’ account credentials may be misused for unauthorized logins - Customer data or confidential documents may be leaked, leading to secondary damages and reputational harm - Your company’s name may be discussed in hacker forums, marking it as a target for attacks

Such risks may be progressing unnoticed.

Moreover, since dark web information changes daily, even if you’ve conducted a one-time investigation in the past, continuous monitoring remains essential. It’s crucial to periodically reassess: 'Are we truly protected?', 'When was the last check?', and 'Did we stop after a single investigation?'

Additionally, even if you detect leaked information, failing to prioritize and properly communicate findings to relevant departments and executives often prevents timely action.

Visualizing Dark Web Risks with QUAXAR—Backed by Track Record in Interpol and Government Agencies This seminar redefines ransomware defense—not as post-incident response, but as proactive action initiated by detecting leaked and circulating information on the dark web.

Specifically, we will explain how to detect leaked accounts, confidential data, and mentions of your organization in attacker communities; how to prioritize these findings; and how to effectively communicate them to relevant departments and executives.

We will also introduce QUAXAR (Quasar), a solution with proven success in international and government agencies including Interpol, demonstrating how to continuously monitor dark web risks and practical strategies for engaging departments and leadership in proactive response.

For interested companies, we offer a complimentary post-seminar follow-up service to check the number of password leaks associated with your employees’ accounts. Use this to understand your current exposure and inform future security planning.

Who Should Attend - Those concerned about whether company information has leaked onto the dark web - Those enhancing ransomware defenses but uncertain if internal protection alone is sufficient - Those seeking to understand risks from leaked accounts or third-party vendors - Those aiming to present dark web risks to executives in a structured, actionable format - CISOs, CSIRT members, IT system departments, and security planning teams
