ChatGPhish: The Page Is the Payload

, , , ,

Researchers discovered a new phishing and tracking attack called ChatGPhish that exploits ChatGPT's page summarization feature by injecting malicious Markdown links and images into web pages. When users summarize such pages in ChatGPT, the assistant renders active clickable links, spoofed alerts, and QR codes within its trusted interface, enabling phishing, cross-origin data leakage, and off-device attacks without traditional browser protections. This expands the attack surface from email to everyday browsing, highlighting risks in AI-generated outputs that automatically render untrusted external content inside trusted AI interfaces.

Abusing .arpa: The TLD That Isn’t Supposed to Host Anything

, ,

Threat actors are exploiting the .arpa top-level domain (TLD), typically not meant for hosting content, to conduct phishing attacks. By using IPv6 tunnels, they create malicious domains that bypass security controls. These phishing campaigns employ tricks like embedding hyperlinks in images, leading victims to malicious sites through a series of redirects. The attack involves manipulating DNS record management to host phishing content, taking advantage of the .arpa domain’s trusted nature. This novel exploitation complicates detection since these domains appear legitimate and are often unblocked by security policies.
