"A Tool for parsing PCAP and capturing network traffic."

Radamsa is the great open source command-line fuzzer for all purposes created by Aki Helin. Aki describes Radamsa like this:

Radamsa is a test case generator for robustness testing, a.k.a. a fuzzer. It is typically used to test how well a program can withstand malformed and potentially malicious inputs. It works by reading sample files of valid data and generating interestringly different outputs from them. The main selling points of radamsa are that it has already found a slew of bugs in programs that actually matter, it is easily scriptable and, easy to get up and running.

Radamsa was originally created in the OUSPG research group.

Get help

Get command line help of the tool this way, using the cincan tool:

cincan run cincan/radamsa --help

or using docker directly

docker run --rm cincan/radamsa --help

Fuzzing a file

Read file 'hello.txt' and produce 10 fuzzed versions of it into directory fuzzed/, with the help of cincan tool:

cincan run --mkdir "fuzzed" cincan/radamsa -n 10 -o "fuzzed/%n" hello.txt

Radamsa argument -n 10 requests 10 fuzzed files. Cincan tool argument --mkdir fuzzed creates the result directory and avoids uploading possible existing fuzzed files into the container.

Alternatively you can use the docker run command and mounting directories to container (you must create directory fuzzed beforehand):

docker run --rm -v $(pwd):/files cincan/radamsa -n 10 -o "/files/fuzzed/%n" /files/hello.txt
