Secure Code Review

A pentest sees the paths you stumble into; a code review sees them all. This is the offensive code-review methodology — stop reading top-to-bottom and start hunting sources to sinks. Map the inputs, grep the dangerous functions, trace tainted data, and read for the access-control checks that are not there. With per-language dangerous-function lists, real Semgrep and CodeQL commands, how every vuln class looks in source, and a copy-paste review checklist.
