Binary Control-Flow Trimming
Masoud Ghaffarinia, Kevin W. Hamlen · 2019
A new method of automatically reducing the attack surfaces of binary software is introduced, affording code consumers the power to remove features that are unwanted or unused in a particular deployment context. The approach targets stripped binary native code with no source-derived metadata or symbols, can remove semantic features irrespective of whether they were intended and/or known to code developers, and anticipates consumers who can demonstrate desired features (e.g., via unit testing), but who may not know the existence of specific unwanted features, and who lack any formal specifications of the code's semantics.
