Hi, I visted a guy's website and I made him really mad. He has my IP address, can he hack me with it? If so, if I change my ip address will that completly stop him 100% from being able to hacking me?

You are of course refering to public ip address assigned by your isp if it is static you can't unless isp has given several addresses to use. If dynamic which means it will change but is no garantee from hacking.

My advice ensure you have a good firewall running and good anti-virus and complimentary anti-malware that doesn't have real time protection to interfere with av, but you can run scans manually to catch things that may have been missed by av.

Consider using a sandbox.

Without more information about the site and what information he may have collected with your 'visit', I will say nothing is 100% with regards to the web. Follow the advice given by Darth sidious about a firewall, consider adding a router, be proactive and you should be ok. Practice safe surfing habits.

As Animal stated "I will say nothing is 100% with regards to the web". But, if all he has is your IP then adding a good hardware firewall and a software firewall on the PC should be good enough. IPs are very over rated in it helping a "hacker". Keep in mind to get inside of your PC, the hacker first has to go through your ISP which are probably running "anti-hacker" tools such as closing common hacker ports, and firewalls inside of their network. Although it could be bypassed, I doubt anyone except people just dedicated to hacking would have any idea.(Translated: The 12year olds from 4chan would probably not know how, or be able to hack it. Most of the people that could bypass it, would be ones with years in PC security.)

When it comes to someone "hacking" you, I'd be more worried about him having access to your email address you used to register, getting a keylogger on your PC to get credit card information, posting your password(s) on the internet, and so on..


---
EDIT: I just want to clarify something before people start posting their IPs: Your IP address should be treated as personal information, just because I say "most people wouldn't know how to hack it", doesn't mean someone out there can't use that, on top of other things such as malware to hack you easier.

I am pretty sure it is dynamic (but I am not totally sure).

My advice ensure you have a good firewall running and good anti-virus and complimentary anti-malware that doesn't have real time protection to interfere with av, but you can run scans manually to catch things that may have been missed by av.

Follow the advice given by Darth sidious about a firewall, consider adding a router, be proactive and you should be ok.

I want 100% asurenence, not 99.9%. Firewalls and AV programs can be hacked, I want 100% security.

Without more information about the site and what information he may have collected with your 'visit'

Hi Animal, what sort of information do you need?

Practice safe surfing habits.

Believe me, I have learned my lesson.

And how come if I change my IP address, I am not 100% safe? Please explain in detail, there is nothing on Google about it.

As I've already stated. Hackers rarely use your IP address to do anything to you. So by changing your IP you're not eliminating the possibility of his site infecting you with a keylogger or some other form of malware. Also, changing your IP is not as simple as just going "okay I want a new IP". Its 100% up to your provider. They may be limiting 1 IP to each MAC address, you may be assigned a static IP, they can be using a proxy server(so thousands of clients share the same IP), or dynamic IPs. You cannot get a guarantee IP change.

The best way to stay secure is to not go crazy and want a new IP or something similar every month, as that offers very little protection. Best way to stay protected is to get a good anti virus, anti-spyware, hardware firewall(such as router), and a good software firewall(install on your PC).

And its good practice to use different email accounts for things like joining websites and your banking information. Never use the same password for your bank, or private(important) email on any website, because not all websites encrypt the password. Even if the site owner does not use the information, in the event of the site being hacked there goes your email/paypal/credit card/whatever username and password. They could also get it and send spammy things to your friends emails, which in return would get them infected and the cycle would continue.

what sort of information do you need?

Although I can't speak for Animal, some of the basic information would be:
-What type of site is it?
-Did they ask you to install any special type of plugin?(ex: to view a special feed or something)
-Did you have to log-in to the site?
-Does the site set cookies, and what where your cookies settings for the browser?
-Did you use any security software, to make sure you weren't infected already? With something such as a keylogger, or hosts file hijacking?

I want 100% asurenence, not 99.9%. Firewalls and AV programs can be hacked, I want 100% security.

This may seem a bit rude of out of place, but the net is not even "99.9% secure". Only way to be over 90% secure is "Don't use the internet". To be 99.9% secure, you'd have to go with Linux, and never use an internet connection. Don't use CDs, or flash drives from anyone. Computers aren't 100% secure. Changing your IP does not even make you 10% more secure. Best way to stay secure is to keep a good anti malware programs, good firewalls, and don't go on sites you don't trust.

Hi, thanks for the reply. Let me explain my situation a bit more. The last time I visted the site was in June. And I have 2 computers hooked up to a wireless router. I have reformated and reinstalled Windows 7 on computer #1 (the one that visted the site) twice.

So please explain to me why I would not be 100% safe if I unpluged both computers and reinstalled Windows 7, flashed the BIOS, and reset the Modem and Wireless router, then got a new IP address, why wouldn't I be 100% safe? And I no longer use the email address I used to join the site.

Although I can't speak for Animal, some of the basic information would be:
-What type of site is it?
-Did they ask you to install any special type of plugin?(ex: to view a special feed or something)

-Did you use any security software, to make sure you weren't infected already? With something such as a keylogger, or hosts file hijacking?

1)Wiki
2)No
3)Yes, I was an admin
4)Yes, I got cookies, but I wiped them 2 formats ago
5)I used avast when I used the site

The owner of the site is a total nut, belive me. I became an admin before he showed his true colors. He brags about how he has been arested for threating to murder people, and me. Believe me, this guy is insane. And when I left the site, I blessed him out. There were only 2 other users (who of course also left).

There is no such thing as 100% garantee there will always be an error factor and the crackers finding new ways of circumventing security hardware and software and security professionals closing the loopholes.

You answered the questions I would have asked and I can't make any other recommendations that haven't already been made. I would merely be parroting the excellent information already given.

I can only reiterate that with regards to the web, 100% security doesn't exist. Silver bullets against malware or attacks do not exist and if someone tells you they do, come back here and we can sell you a slightly used bridge in excellent condition, cheap. :thumbsup:

I can't state enough that 100% security and safety while using the Internet does not exist. Reputable sites like Time, various Fortune 500 companies who pay millions of dollars to be 'secure' get hacked. So to think that your less than 1 million dollar, if paid for, security set up can keep you 100% safe is nothing but a dream. I don't know any other way to make that point and help you understand what you hope for is unattainable as long as you visit the web. Like any large city anywhere in the world, bad and unsavory people lurk. All you can do is protect yourself the best way known, or lock yourself in a fortress and never venture out.

The Internet is so big, so powerful and pointless that for some people it is a complete substitute for life.

Hi, but can you please explain why I won't have 100% security from him, if I do what I said I was going to do? Isn't that equal with moving to another house in another country with a new computer? I never shared my real name, only my age and what state I live in. So there is no way for him to stalk me in real life from the info I provided.

As everyone here keeps trying to stress to you; THE INTERNET IS NOT 100% SAFE. It doesn't matter how much security software you use, or if you only go to sites such as Google. You can be hacked or infected from doing nothing more then being on the internet. You don't have to go to illegal sites, porn sites, etc. to be infected or hacked. Just simply having an infected PC on your network could corrupt your router's DNS/IP settings(although unlikely, but still possible), and by doing that every time a different PC requests a new IP/DNS information, they would get the "hacked"(for lack of a better word) information, and then get infected themselves. Viruses can also spread between computers, without "infecting" the router.

Its way too many things to list that could still be used to "hack" you. If you where using programs like Windows Live Messenger, or AIM, a good enough hacker could probably turn that against you. If the guy knows some of the other sites you visit and is a real "hacker" out to get you, he could hack those sites then get your new email/IP/password/etc. Once again, its no way to be 100% safe.

1)Wiki
2)No
3)Yes, I was an admin
4)Yes, I got cookies, but I wiped them 2 formats ago
5)I used avast when I used the site

1) Good. That lowers the risk of an infection. If it was a illegal site or a video site it would've raised the chance of you getting infected or your information "hacked".
2) Another good sign. If you didn't install anything from the site - then thats good.
3) Did you use the same password on the site for the email you registered on the site with? Do you know what type of "Wiki" software they where running?
4) Okay.
5) Atleast you had protection. I'd recommend scanning both PCs with Malwarebytes just to make sure, you're clean. Also post a ipconfig /all in your next reply and I'll look over your IP/DNS settings to make sure they're legit.

---
Bottom line: You can do many things to improve PC security, but any computer connected to the internet is at risk of being infected and the user having their security hacked. You seem to have done many things correctly to try and make sure your PC is secure, which is a good thing. Keep doing that, take weekly(or daily if you have enough free time) scans of your computers, check your router settings randomly, and change your passwords frequently. Always make the passwords different from each other, it's better to use letters, numbers, and symbols(ex: AFT23$#$ffdg@9) vs a simple word or numbers. I believe the standard "secure" password length is currently 12-16 characters. But once again, after you do all of this: it only makes you more secure. It does not make you 100% secure.

Changing your IP address really does nothing. Chances are its in the same range as the other(ex: 1.1.1.1 changed to 1.1.1.8), and anyone decent in "hacking" could turn that against you, by simply hacking other sites you visit then getting that new IP. (note: I'm talking about worst case here, chances are the guy will give up long before he hacks a site to get your information....)

Hi, but can you please explain why I won't have 100% security from him, if I do what I said I was going to do? Isn't that equal with moving to another house in another country with a new computer? I never shared my real name, only my age and what state I live in. So there is no way for him to stalk me in real life from the info I provided.

Lets look at it this way. Since you compared it to "moving to another house", i'll use the same example.

Lets take your IP address is your address, you move changing your IP address. However, are you willing to give up the same routines? Sites you go to, sites you post on, your style of email addresses, passwords, etc.

Even if you move to the middle of the desert, hire armed security to patrol your house, and have no real "address" someone could still "get in". Imagine the armed security being virus protection and the person getting in being a hacker.

This is a crappy example, I know. But it should make the original point pretty clear: It's no way to be 100% secure, all you can do is do your best and hope that you don't get infected or hacked. After doing what you've said, I think you're ok, but no one is going to tell you thats its a magic solution to be 100% secure on the internet - or any solution to be 100% secure(except maybe the marketing team for an anti virus company....).

Hi NpaMA, you see I am not worried about other viruses, and being hacked by other unrelated people. I want 100% security from this nut. You see I never used my real info besides my age and what state I live in. I commonly use diffrent online ID's, and I abandoned the one I used to register on that site in June. And even if he did hack my abandoned email account he would only find info about other sites that I have abandoned. Once again the only real info he would find would be my age and state.

So let's say he hacked every account I made with that ID, he would only find my old IP address, my age and state. What could he do with that? My guess is nothing.

Oh, and I am also using a new email address.

Changing your IP address really does nothing. Chances are its in the same range as the other(ex: 1.1.1.1 changed to 1.1.1.8), and anyone decent in "hacking" could turn that against you, by simply hacking other sites you visit then getting that new IP. (note: I'm talking about worst case here, chances are the guy will give up long before he hacks a site to get your information....)

But I guess he could simply hack every computer on that range until he finds me. So how do I get a complety new IP address? By changing my ISP?

By getting your IP, he may be able to even get it down to the city. But other then that, I don't see anything else he could do. If you're not interested in preventing FUTURE attacks from others, and just from this one guy then you should be "generally safe" from him hacking you. Once again, nothing on the internet is 100% secure.

The idea of "hacking" PCs, is over rated and misunderstood...alot. A person does not take an IP address then open up a program to gain instant access to the computer. Its many things that have to be bypassed, and pretty much all hacks to a COMPUTER(not a server that can process scripts such as PHP), are done by the user first installing something on their machine, which then contacts the hacker's computer/server and allows the connection.

All computers on the same network(read: router) share the same internet IP.

Well, I know it is possible becuase I found on a google a tutorial a 13 year old made, that shows you how to hack someone with just an IP.

All computers on the same network(read: router) share the same internet IP.

Yes, I know. I don't want a new internal IP address, I want a new external address.

One other thing, if I do get in a new IP address, and I wipe my computers and abandon the ID I used to register on the site, how can he hack me, I just don't see how.

I feel 99.9% confident enough to say: It's fake. Most youtube videos about how to hack something are fake.
