Claude Code Security and Magecart: Getting the Threat Model Right

When a Magecart payload hides inside the EXIF data of a dynamically loaded third-party favicon, no repository scanner will catch it – because the malicious code never actually touches your repo. As teams adopt Claude Code Security for static analysis, this is the exact technical boundary where AI code scanning stops and client-side runtime execution begins. A detailed analysis of where Claude

IPv4 Mapped IPv6 Addresses, (Tue, Mar 17th)

Yesterday, in my diary about the scans for "/proxy/" URLs, I noted how attackers are using IPv4-mapped IPv6 addresses to possibly obfuscate their attack. These addresses are defined in RFC 4038. These addresses are one of the many transition mechanisms used to retain some backward compatibility as IPv6 is deployed. Many modern applications use IPv6-only networking code. IPv4-mapped IPv6 addresses can be used to represent IPv4 addresses in these cases. IPv4-mapped IPv6 addresses are not used on the network, but instead, translated to IPv4 before a packet is sent.
