![]() In LOCAL mode, they can only communicate with EXAs in the same host - and very importantly, only with other EXAs that are also in LOCAL mode. You can swap them to LOCAL mode using the MODE command, or at the start by clicking the toggle on the M register. That means they can receive and send messages over M from any friendly EXA in any host. ![]() I've talked about communication modes but I've not needed them so far so I'll explain it again:ĮXAs, by default, start in GLOBAL communication mode. This is faster and also saves a couple cycles for a larger dictionary. Instead, invest in a proper password manager.Īnyway, silentsnack came up with a further improvement.ĬOPY M F32 and as noted XA and XB need to start in local communication mode, which dunno if you've covered that yet.Yeah, so the idea is the same, but the file (which took time to write) has been replaced by an EXA which sends the dictionary over the M register. ![]() If it gets leaked in one place, hackers will first try that same password for all your other accounts. That's why you should never use dictionary words as passwords (use random characters instead), and you should never reuse passwords across sites. Sounds much less like bullshit if I phrase it this way, wouldn't you say? So this solution makes for a good real life lesson: hacking into an account is much easier if the hacker has foreknowledge about likely passwords. Thinking about it, what silentsnack actually did was change a brute force attack into a partial dictionary attack. If none of those 20 passwords are correct, it brute forces the range that wasn't tested yet, but that's now much smaller. This means you never have to brute force all the way into the 950s, and it also means you can skip the first 200 or so passwords because we already know which passwords in that range are used. Looking at them, I think they're the 17 lowest passcodes and the three highest from the test set. So, XA starts with writing a whole bunch of values into a file (in the home host so that file won't get in the way later), then sends REPLs to test each value in the file. COPY M F48 - bullshitting our way to crazy statistics Hahaha, this code is quite the sight.
