Wenn KI den Angriff erfindet Browser-native Ransomware
Keine App. Kein Exploit. Keine technischen Kenntnisse erforderlich schon ein einziger Klick zur Erteilung einer Browserberechtigung könnte Jahre an Handyfotos, Ausweisdaten und Wiederherstellungscodes gefährden. Die Sicherheitsforscher von Check Point Research haben ein von Deepseek generiertes Malware-Sample aufgedeckt. Dabei hat ein KI-Modell eigenständig ein theoretisches Browser-Risiko mit einer funktionierenden Ransomware-Technik verknüpft. Diese wird vollständig im […]…

Phantom Squatting Uses AI-Hallucinated Domains for Phishing and Malware
Large language models keep inventing web addresses that do not exist. Attackers have started buying those made-up domains before anyone else can, then hosting phishing pages on them to catch traffic that AI tools point their way.Palo Alto Networks’ Unit 42 calls the trick phantom squatting, and its new research shows it is already happening…

Attackers Register AI-Hallucinated Domains to Deliver Phishing Kits and Malware
An emergent supply-chain attack vector they term >>phantom squatting,<< in which large language models (LLMs) routinely hallucinate plausible but nonexistent domains for legitimate brands and adversaries then preemptively register those domains to host phishing kits, malware, and other malicious infrastructure. By systematically probing two distinct LLM families across temperature settings, Unit 42 generated a 2.1…
