Hackers Exploit Ollama Model Uploads to Leak Server Data
Cybersecurity researchers have uncovered a severe, unpatched vulnerability in Ollama, a popular open-source platform used for running large language models locally. Tracked as CVE-2026-5757, this critical flaw exists in Ollama’s model quantization engine. If exploited, it allows an unauthenticated attacker to steal sensitive server data by simply uploading a maliciously crafted AI model file. How…

Warum Unternehmen jetzt ein ganzheitliches Exposure Management brauchen Der Allgefahrenansatz der NIS2
Mit der Verabschiedung des NIS2-Umsetzungsgesetzes durch den Bundestag stärkt der Gesetzgeber nicht nur die Resilienz kritischer Sektoren, sondern verankert gleichzeitig den sogenannten Allgefahrenansatz fest im deutschen IT-Sicherheitsrecht. Dieser Ansatz macht unmissverständlich klar: Cybersicherheit darf sich nicht länger auf die Behebung einzelner technischer Schwachstellen beschränken sie muss alle Risiken entlang der Geschäftsprozesse berücksichtigen.
