Contact for "Forensic Investigation Support"
CoWorker Inc. (Headquarters: Shinjuku-ku, Tokyo; Representative Director: Kazuki Yamasato; hereinafter "our company" or "CoWorker"), a company that develops and provides AI security solutions, has launched a "Forensic Investigation Support Service" for lawyers and corporate legal departments. This service supports PC and device investigations in situations where troubles with retired employees or internal misconduct by employees are suspected.
This service is characterized by its ability to conduct fraud investigations, which traditionally tend to be expensive and prolonged, more affordably and speedily. This is achieved by combining the forensic analysis platform (high-speed analysis of device logs) powered by our proprietary AI "Blue Agent" with reviews by security experts. It supports evidence preservation and fact-finding with a view to legal action, such as data exfiltration by retired employees, suspected theft of trade secrets, and device investigations related to embezzlement or other illicit acts.
Background of Development and Provision
Frequent incidents of information exfiltration and leakage, and the importance of initial response required of corporate legal affairs
In recent years, fraud risks surrounding companies have expanded beyond external cyberattacks to "internal origin" risks, such as information exfiltration by retired employees and internal misconduct by employees. According to the National Police Agency, the number of arrests in cases of trade secret infringement in Reiwa 7 (2025) was 38, an increase of 72.7% from the previous year, with many cases of trade secret information being taken upon job change or independence.
Furthermore, the annual report of the Personal Information Protection Commission shows that in Reiwa 6 (2024), 19,056 reports of personal data leakage and similar incidents were processed, highlighting the increasing importance of responding to information management incidents in companies and organizations. The IPA's "Top 10 Information Security Threats 2026 [Organizations]" also lists "information leakage due to internal misconduct" as the 7th threat, positioning the exfiltration of confidential information and illicit acts by insiders as a major management challenge that can lead to loss of social trust and economic damage.

For instance, in 2025, SoftBank announced the possibility of personal information leakage involving approximately 140,000 cases due to a subcontracting company. Also, at Recruit, a case where a former employee took internal documents out of the company just before retirement was made public. Such information exfiltration and inappropriate handling are real risks regardless of company size or industry.
On the other hand, device investigations and forensic investigations to confirm the presence of misconduct have traditionally faced a significant hurdle due to high costs, with some cases reaching several million yen per device. Consequently, even for incidents that warrant a PC investigation, it is not uncommon for sites to face challenges such as "too expensive to initiate" or "delayed initial response, missing the timing for evidence preservation."
To address this challenge, CoWorker has utilized its proprietary AI "Blue Agent" for its forensic analysis platform to streamline part of the investigation process, enabling support at a more accessible price range and shorter turnaround time than before. We provide a "realistic fraud investigation method" that can be promptly initiated when needed, in the context of corporate legal affairs, labor issues, and scandal responses handled by lawyers.
