hahaha theoroleticaly yes someone can hack your computer by knowing your ip. but it would take an amazing amounts of skills to do that and someone who has that skill level wouldn't be playing minecraft and getting mad at people. But really it depends on your firewalls and such because it would as I said be insanely hard to hack a computer just by knowing the IP.

"put it in a hack machine"

That's the exact moment that you stop worrying and laugh.


Hacking with an IP with less than 10 open ports is very difficult, and most people don't find it worth the effort.

I agree. There is no way anybody (except Anonymus) could hack you. Just a big bluff.

10 ports? That number seems awfully arbitrary (and inflated), seeing as many webservers have far fewer ports than 10 open and can get hacked....

An IP and 1 port is all that's necessary to get hacked, given that one port is open for a server app that is exploitable and the person threatening to do so knows how to.

(and no, that person threatening the OP does not have this knowledge, so don't worry)

Yes, but how many average people are hacking websites?

(In that mindset, you can really apply that to anything. i.e. you will only die one way, so you can do anything else you want. but I digress..)
I merely say 10 as a line between what's more likely/less likely to be vulnerable to someone with not above average skills in exploiting.

I'm saying, while the possibility of some random person hosting minecraft being a target is exceedingly low, '10' is a line that is without any basis or merit. People call out hamachi all day as being hackable, that's one port open. Many enterprise webservers have 2 or 3 ports open; they are susceptible to hacking. I can hardly think of a server that would have TEN ports open at all unless they're trying to get hacked...how many public-facing services does one machine need?

webserver, vent, ssh, minecraft, ftp, rsync, mysql, dynmap...well, that's only 8.  No worries though, with under 10 ports open, the risk is negligible....not one of those ports on their own could ever be taken advantage of, most hackers wait till they have even more ports. Clearly what's more important than the port count is the competence of the admin, the security of the server software, and well, I'm sure other things factor into safety, like firewalls.

TLDR: if a minecraft exploit ever gets discovered, i guarantee they'll only need one port open to exploit it--a script kiddie can download and execute a file pretty easily.

If you want to reassure him, assure him that the software he is running has yet to be exploited, not 'you haven't enough servers open to be at risk yet!'

True, but there's also some standard ports (21, 80, 440, some windows/linux have something in 6600-6700 open). But ofc it's about the actual measures/precautions taken by who is behind it, as well as the service. In short, you have a completely valid point.

One could "hack" your machine and network by knowing your IP. This takes a lot of skill and know-how. Since "hack machines" don't exist, I doubt they know what they are talking about, or have the technical skill to pull off the hack. They told you this to scare you. I wouldn't worry about it.

Forget it. Yes you can be hacked with an open port and IP address, but no that guy cant hack you.

Take it from everyone on here, if someone says they are going to hack you/your server/anything else for that matter, chances are they have no clue what they are talking about and are just being general douches because they don't like what you are doing.

And "Hack Machine" is hilarious, i needed that laugh, thanks.

- Actual Hacking -

OK, if you are talking about actually getting your information, then no. No Minecraft player is going to hack you because you banned him. If they do, they could be put in jail.

- Possible Situation -

He could get a BotNet and DDOS you which is also illegal but rarely reported unless it is something major. The only thing that would do is take your Internet down for a few mins or so depending on how long he wants to attack.

Technically, Is it possible? Yes, it is.

Is somebody going to try and do it, and spend all the time and effort? Most likely Not.

If you think it is a big threat, just report it. And Honestly, A "Hack Machine" The guy probably is just wanting attention and trolling you. Simple as that.

Yes, you can get a hosting company.  I would recommend beastnode.

I would not recommend BeastNode UNLESS they have fixed their problems. They have been hacked before. I would make sure it is completely secure!

With modern botnets and other DDoS tools? He could hold you offline for days. Heck, depending on the scale of the attack and the age of your modem, a five-second DDoS could be enough to crash it, eliminating the need for a prolonged attack.

I was DDoS'd at home once in June. My modem instantly died, even reboots wouldn't fix it. I ended up having to replace it. Granted, I got hit with 400+Mbps of pure SYN (at least judging by the attacks on my dedi at the same time), but still...

A reasonably large attack could easily bring down your entire neighborhood's node (assuming you're on a service that uses nodes). I've seen some attacks that are large enough to knock out a small regional ISP's entire network.

Personally, with my experience in this particular area of networking... I'd suggest never running any type of public server from home.
i7-3770K @ 4.5GHz, Hyper 212 Evo, 16GB 1600MHz RAM, Z77X-UD5H, GTX 670 OC, 256GB 840 Pro, 2TB + 500GB HDDs, Fractal R4, HX750 (with bonus fan noise), Dell U2713HM.

I was not aware of that.
