Quandary is a static taint analyzer that identifies a variety of unsafe
|
|
information flows. It has a small list of built-in
|
|
[sources](https://github.com/facebook/infer/blob/master/infer/src/quandary/JavaTrace.ml#L36)
|
|
and
|
|
[sinks](https://github.com/facebook/infer/blob/master/infer/src/quandary/JavaTrace.ml#L178),
|
|
and you can define custom sources and sinks in your `.inferconfig` file (see
|
|
example
|
|
[here](https://github.com/facebook/infer/blob/master/infer/tests/codetoanalyze/java/quandary/.inferconfig)).
