7/5 ニコ動 流出は0.8Tで半分のみ。第二弾流出の可能性
公表された流出被害総量は 1.6TB だが、7/5現在流出が確認されてるデータ量は半分の0.8Tに過ぎないことが判明しました。第二弾があると思われます。
段階的なデータ公開か？
過去のKillNetの行動から見ると、彼らは段階的なデータ公開や、公開したデータを政治的・戦略的な目的で利用することが多いです。彼らは、DDoS攻撃、データ漏洩、情報操作キャンペーンを通じて、インフラストラクチャ、政府のウェブサイト、民間企業を標的にしてきました (Wikipedia) (SOCRadar® Cyber Intelligence Inc.) (Cyberint)。
7/5現在、第二弾のデータ流出に関する具体的な情報はありませんが、KillNetのTelegramなどのコミュニケーションチャネルでの発表を監視することが重要です (InfoSec News) (N2K CyberWire)。彼らは過去に、初回の公開による成功や反応に基づいて、さらなる攻撃や追加のデータ流出を計画する傾向があります。
KillNet, a pro-Russian hacktivist group, has been actively involved in cyberattacks and data leaks targeting organizations and countries that support Ukraine. Recently, they leaked 0.8TB of data from Dwango, which is reportedly half of the total 1.6TB they possess. This partial release suggests the possibility of a second wave of leaks, potentially as leverage for further negotiations or demands.
KillNet has a history of staggered data releases and using leaked data for political and strategic purposes. They have previously targeted critical infrastructure, government websites, and private companies, often with follow-up attacks or additional data dumps to maximize impact and pressure on the victims. Their tactics usually involve DDoS attacks, data leaks, and misinformation campaigns (Wikipedia) (SOCRadar® Cyber Intelligence Inc.) (Cyberint).
Given their past behavior, it is likely that KillNet could use the remaining data as a bargaining chip or to maintain public attention and pressure. They might demand a ransom, make political statements, or coordinate further attacks based on the initial release's success and the reactions it generates.
For the most current situation, there is no concrete information indicating specific plans for the second leak at this moment, but monitoring KillNet’s announcements on platforms like Telegram and other communication channels will be crucial for updates (InfoSec News) (N2K CyberWire).
