gtfocli search -f myBinaryList.txt

Search for windows binaries

Search for binary Winget.exe:

gtfocli search Winget --os windows

gtfocli search Winget -o yaml --os windows

Search using dockerized solution

Examples:

Search for binary Winget and print output in yaml format:

docker run -i cmdtoolsowner/gtfocli search Winget -o yaml --os windows

Search for binary tar and print output in json format:

echo 'tar' | docker run -i cmdtoolsowner/gtfocli search -o json

Search for binaries located into file mounted as volume in the container:

cat myBinaryList.txt
/bin/bash
/bin/sh
tar
arp
/bin/tail

docker run -i -v $(pwd):/tmp cmdtoolsowner/gtfocli search -f /tmp/myBinaryList.txt

CTF

An example of common use case for gtfocli is together with find:

find / -type f \( -perm 04000 -o -perm -u=s \) -exec gtfocli search {} \; 2>/dev/null

or

find / -type f \( -perm 04000 -o -perm -u=s \) 2>/dev/null | gtfocli search
