For anyone who skims, not reads, this particular exploit is four years old.
I’ve never worked with anti-virus definitions, but I assume blocking out the entirety of Metasploit would be as simple as finding the common markers left in it’s generated payloads and make sure you computer scans opened files in real time Incase the infected program is encrypted (which it most likely is).
The craziest part about reading that guide was the comment section. One of them actually asked, “can you please tell how to write the path and filename”
Also, there were a group of people on there asking about a specific error they got when trying to compile the file, one that was as simple as forgetting to set the target file’s name.
What kind of jackasses are these people? Do they seriously have this little of computer savvy, but think they can write viruses? It’s idiots like that that can almost guarantee that anti-virus/malware developers get these kinds of programs in their definitions PDQ.
It wouldn’t surprise me if the entire program itself, Metasploit, was just one massive virus designed to attract amateurs who think they can do anything by reading a single guide.
