Does using an SSH .rsa key instead of a password make it harder or easier? If you gained like a meterpreter shell into one computer, couldn't you theoretically just find the .rsa SSH credentials?
@@uniquechannelnames Attacking a remote system with passwords can be done by anyone anywhere. To hack a system protected with key based security, you must actually find the private key which is something that even the secured machine will not possess. This means the attacker must first successfully hack the admin’s machine to get the key. This is also why you should protect your private keys with a supplemental security layer. A keychain, password manager, or even simple password can make this impractical for all but the most dedicated hackers.
Not planning on hacking any SSH, just looking to see what Im up against as a server operator. Don't know why though. I already use public keys with password and root auth disabled, custom port, and fail2ban.
Thank you for this tutorial. After setting the user file and pass file and attempting to run the command. It brought an error message and I realized I didn't have the user.txt and password.txt files. Please how can I create those files?
Could you do a video on discovering what file types a server allows? I have done boxes where for example php might not have been allowed but php5 was allowed. So would be useful to have a strategy of checking such things (other than trying multiple versions I guess)
ss-gopy your public key to server and login xD oh wait you need password..but what if... you cant brute force if server would my design you get blocked after couple password try LOL and shh has open port...
Nobody should be using SSH1 nowdays, so not sure how useful it will be trying to hack into SSH systems using v1 when practically nobody is (should be) using it.
Great, so how do we defend against this aside from using a stronger [*nix account] password? Is there a way to time-throttle login attempts? The *MaxAuthTries* and ** settings are barely a minor speedbump for a script and *LoginGraceTime* setting won't help at all (it's essentially useless ¬_¬). A quick search seems to indicate that you'll have to use iptables to set up a time limit. Why isn't there a built-in option in sshd? 😕
To defend against this, as Kody said, you can use an obscure username (disable root/admin ssh logins), use a different port and use a strong password or - even better - use a private key. You can also set fire wall rules that either limit how many login attempts are allowed per minute or deny access to the source IP after a certain number of failed attempts within a time period. On my box, I only allow ssh access for a named user using a private key and that's successfully defended me for years. Recently I added a firewall rule (3 lines actually) to boot people after 4 failed attempts within a minute 'cause my logs were filling up with failed login attempts.
Commercially: Certificate based auth, but that requires you to set up a PKI infrastructure which is a bit beyond the personal use so... Personally: switch to Public Key auth, disable root login, use ip tables to limit connections, install and configure 2fa (Google authenticator is free). You can still brute force public keys (if you have a collection of them - say HDMoore's collection of Debian weak prng generated keys) using something like crowbar but it's not likely that your key generated by a modern operating system is going to be in that collection. Password auth itself needs to die in a fire.
@@lmaoroflcopter agreed but without Google if you change phone or worst lose it, your screwed. Lost access to several places for a few days. Cloud based authentication is the way to go imo
@@christopherirving7685 that's why you back up your backup codes to something that isn't your phone, and Google Auth, is just an open source implementation of TOTP.

Any decent SSH install has: 1) Disabled root login, 2) Disabled password login in favor of public key, 3) A method of stopping the 'attack'; usually by blocking the IP for at least 24 hours or something.
@Losko That's where we disagree: Step #4 doesn't CONSIDERABLY reduce the "impact surface". It MARGINALLY, if at all, reduces the "impact surface". With tools like nmap you can scan all ports in a matter of seconds and if your system is connected to the public internet then tools like Shodan make it so easy even kids can find your "hidden" SSH service. (See security.stackexchange.com/a/189738/3992 )
any half decent hacker will just use a botnet to bruteforce the credentials so banning IP does nothing really. Especially when someone has hundreds of thousands of telnet devices on their net.
@@Sythorize Ofcourse it does, it limits the number of attempts to X for each and every IP. Yes, your banned IP list will grow big, but it's still better than keep allowing each IP to try again and again and again.
Tried to ssh the router, but it says port 22 refused .. Tried telnet aswell but port 23 refused .. What can i do about this ?? Connect bot is not working ..
cat /var/log/auth.log | grep Failed | wc -l if the number is more than 2 digits, you should probably pay attention. Change ssh port to at least 4 digits and turn off root user login

I think that as long as you have the IP of the target. You have their IP, you scan for open port 22 and just brute force it. Give me your IP and I will try if it works lol
Null byte help me. I m learnin from live kali linux on laptop. When i try hacking wifi my wifi will be disconnected. My linux not scan wifi. If i click restart button it will be fine. I dont know what would i do. If wifi working but not scaning any targets. Help me. I am from Uzbekistan. I don't know English very well. Sorry if have any mistake in my letter.
Network services are disabled by default in Kali. To enable them, try "sudo systemctl network.service start". It is disabled by default as a computer looking for a wifi is exposed, so it gives out its location. Also you may need a wifi dongle if your laptop does not support it. Hope this helps. (P.S. Don't do anything *illegal or criminal,* and if you are scanning ports, use proxychains to hide your ip and prevent dns leaks.)
The actual aircrack-ng FAQ suggests the following - please keep in mind that the model suggested by the comment above might crash your kernel! • Alfa AWUS036ACH (a/b/g/n/ac) is the best performing card, but the driver can be unstable enough to crash your kernel. • Alfa AWUS036ACM (a/b/g/n/ac) is the highest performing of the STABLE devices, but it requires kernel 4.19.5 or higher, and the driver doesn't work on the Raspberry Pi 3 yet; it works on the Raspberry Pi 4.
It shouldn't. iptables should kick in and make the attacking computer think that the server is now offline and wont respond to pings. But I could be wrong. I run fail2ban on all my servers though! Currently at 37678 Blocked IP addresses :D
@@misfitsman805 hectic! Would be cool to build a dmz in front and drop a honeypot in there. See what these bots/peeps are up to.

exploiting IS NOT bruteforcing YOU ARE CONFUSING beginners, it's impossible to bruteforce a good set password
Another easy way to protect against this, besides using public keys, is to block IPs after a set number of failed ssh logins in your firewall config.
