I know I'm late to the party and this is probably the stupidest question in the world but one never knows unless one asks, yeah? How did he/she know the binaries were packed with upx?

There's various analysis tools that can identify common packers, and I think you can at least guess UPX by looking at the file contents and seeing the string "UPX" a few times, which it uses as markers for something.
