threat of targeted attacks continues to intensify, having been listed in the \"10 Major Security Threats 2025\" for the 10th consecutive year, which underscores the need for ongoing vigilance. The Behavior Observable System (BOS) dataset, one of the datasets provided by the anti-Malware and anti-cyberattacks engineering WorkShop (MWS) for cyberattack countermeasures, has specialized in the dynamic observation of malware attached to targeted attack emails; however, its updates had been suspended since 2019. In line with the MWS's objective to establish standard datasets for research, this study aims to create and provide the BOS2 dataset as a successor to the original BOS dataset for observing cyberattack behaviors dynamically. In this paper, we address the challenge of reduced visibility in attack activities due to malware's use of encrypted communications, an issue identified during the trial of the 2024 BOS2 dataset. To overcome this, we constructed a novel observation environment equipped with decryption capabilities. Furthermore, we report on the 2025 BOS2 dataset, which is constructed based on the observation cases obtained using this new environment.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-03-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2026-CSEC-112"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"created":"2026-03-05T05:48:13.126375+00:00","updated":"2026-03-05T05:48:18.140277+00:00"}
