Download some Ubiquiti firmware

wget https://dl.ubnt.com/firmwares/XC-fw/v8.7.11/WA.v8.7.11.46972.220614.0420.bin

Run binwalk with the -e option to extract the binary file

binwalk -e ./WA.v8.7.11.46972.220614.0420.bin

Binwalk should create a _WA.v8.7.11.46972.220614.0420.bin.extracted directory which we should be able to browse. The main “filesystem” is under squashfs-root.

# ls ./_WA.v8.7.11.46972.220614.0420.bin.extracted/squashfs-root
bin dev etc init lib mnt proc run sbin sys tmp usr var
