CAFA: A Checksum-Aware Fuzzing Assistant Tool for Coverage Improvement

Algorithm 1

Identifying checksum points using the CRC32-S strategy.

Input: a well-formed sample (w)

and a malformed sample (m)

Output: CP (checksum points)

(1) , ,

(2) Run the well-formed sample (w) for taint analysis

(3)

(4) Run the malformed sample (m) for taint analysis
