Friends among my various hacker spaces have shared links to a new tool called Updog created by Sc0tfree. A python3 implementation of an HTTP server that is intended to replace Python2’s SimpleHTTPServer module. I had to test it out myself and these are my opinions. In many hacker training courses, it is vital to be able to host your tools on a web server to download them onto target machines. One example would be to download a network scanning tool once you’ve gained a shell on the first machine of a target network.
