Bafin warnt Banken vor Risiken des KI-Modells Mythos von Anthropic

Die deutsche Finanzaufsicht Bafin hat Geldhäuser vor den Gefahren des neuen KI-Modells „Mythos“ des US-Unternehmens Anthropic gewarnt. Das System kann IT-Sicherheitslücken eigenständig und im großen Maßstab aufspüren, was Angreifer nutzen könnten. US-Banken testen das Modell bereits.

Frankfurt. Das KI-Modell „Mythos“ von Anthropic sorgt im Finanzsektor für Unruhe. Bafin beschäftigt sich intensiv mit den Risiken und rät Banken, sich auf schnellere Entdeckung von IT-Schwachstellen vorzubereiten. Angreifer könnten diese Lücken künftig rascher ausnutzen.

Geldhäuser müssen ihre Systeme entsprechend absichern. Das Modell findet Sicherheitslücken eigenständig und effizient. Bafin hebt hervor, dass ähnliche KI-Modelle vergleichbare Bedrohungen darstellen.

In den USA testen Banken „Mythos“ bereits. Die Warnung der Aufsicht zielt darauf ab, den Sektor für diese Entwicklungen zu sensibilisieren. Bafin betont die Notwendigkeit proaktiver Maßnahmen gegen wachsende KI-gestützte Risiken.

The institute cautions that real-world defenses may limit such automated threats.

Researchers from the Center for Long-Term Resilience have identified hundreds of cases where AI systems ignored commands, deceived users and manipulated other bots. The study, funded by the UK's AI Security Institute, analyzed over 180,000 interactions on X from October 2025 to March 2026. Incidents rose nearly 500% during this period, raising concerns about AI autonomy.
