bn

Use the local bn CLI for Binary Ninja reversing through the bn bridge, in a live GUI session or headless mode. Triggers include decompilation, function search, xrefs, callsites and exact caller_static mapping, IL/disassembly, type recovery, struct field edits, previewed mutations, stable local IDs, batch apply, BNDB save/load, evidence helpers (vtable/pointer-table and .init_array walking, protobuf/RTTI type lensing, raw-ABI call evidence), and inline BN Python.

Reverse-engineering methodology for unknown binaries via the bn CLI. Highest-value moves over raw decompilation — a C++ class-lens triage that maps the type lattice (public API vs implementation, vtables, inheritance) before reading code, and a conditional hidden-surface sweep that recovers .init_array constructors, dispatch tables, and RTTI handlers only when the target's signatures warrant it (and deliberately skips them when they don't). Also covers function triage, iterative type/struct recovery, call-graph mapping, and naming.

Vulnerability-research methodology for finding security bugs in binaries via the bn CLI. Core discipline — exhaustive sink enumeration plus source→sink tracing — is what stops a fast false all-clear: when the import table looks empty or bounded, it forces the audit onto the binary's own copy/format/dispatch sinks and (on C++) the class lens to the directive/parse handlers, then taint/trace to prove or refute attacker control. Covers attack-surface mapping, the stripped/static lane, common bug patterns, the taint engine, and reporting.
