インシデント 929: AIを活用したロシアの継続的な偽情報キャンペーン「ドッペルゲンガー」、「ストーム1516」、「マトリョーシカ」がドイツ連邦選挙を妨害したと報道

概要:

2025年2月23日のドイツ連邦議会選挙を前に、ロシアの「ドッペルゲンガー」、「ストーム1516」、「マトリョーシカ（オーバーロード作戦）」とされる偽情報キャンペーンが、AI生成のディープフェイク動画やフェイクニュースサイトを利用して、ドイツの政治家や著名人に関する虚偽の主張を拡散していると報じられています。AIボットがソーシャルメディア上でこれらのコンテンツを拡散しているとのことです。研究者らは、このキャンペーンはドイツの民主主義プロセスへの信頼を損なうことを目的としていたと示唆しています。ドイツ国内情報機関（BfV）は、その規模は前例のないものだと述べています。

Editor Notes: As with most disinformation campaigns, this incident presents certain editorial challenges. Here is a reconstruction of the reported timeline of events pertaining to this incident: (1) On November 12, 2024, Germany announced a snap federal election following the collapse of Chancellor Olaf Scholz’s coalition government. (2) On November 21, 2024, John Mark Dougan, a former U.S. sheriff’s deputy who received asylum in Russia, is reported to have begun registering dozens of fake German news websites to spread disinformation. (See Incident 701 for more information on him.) (3) By February 2025, the number of these fake news sites had reportedly grown to 102, some masquerading as national news outlets, others as local media. (4) Earlier, in January 2025, Elon Musk interviewed Alice Weidel, co-leader of Alternative for Germany (AfD), for 75 minutes on X, which reportedly further amplified AfD’s reach. (5) Also that month, deepfake videos reportedly connected to this campaign began appearing online, including a purportedly manipulated video of Natalie Finch, a British mental health nurse, whose promotional video for the University of Bradford was altered to falsely discuss Germany’s Christian Democratic Union (CDU). (6) On January 30, 2025, a fake news site is alleged to have uploaded a deepfake video falsely claiming that Vice Chancellor Robert Habeck conspired with Ukraine to steal 50 paintings from a Berlin art gallery. (7) Around the same time, another deepfake video is reported to have falsely implicated Friedrich Merz, the leader of the CDU and a front-runner for chancellor, as a "person of interest" in a 20-year-old murder case. (8) Throughout January 2025, bot networks allegedly linked to Russian disinformation groups amplified false claims on X, Telegram, Facebook, and Bluesky, with reports suggesting that they largely were supporting the AfD and targeting mainstream political figures. (9) By early February 2025, Russian-linked bot networks had reportedly driven 2.5 million views to disinformation content on X, tripling engagement levels. (10) On February 13, 2025, the Institute for Strategic Dialogue released a report detailing the extent of Russian disinformation and AI-driven election interference in Germany.

Depending on which investigation one reads, Doppelgänger and Matryoshka may receive more or less emphasis. For example, while The New York Times mentions Doppelgänger and not Matryoshka, the ISD mentions Matryoshka and not Doppelgänger. Please also refer to Incidents 909, 931, 1060, and 1061 when studying this incident. While Incident 931 has not been explicitly attributed to Operation Overload (also known as Matryoshka or Storm-1679), its thematic content and manipulation tactics appear adjacent. (No direct forensic or institutional linkage has been established as of this writing.)
