How Hackers Use Your IP Address to Hack … – Business Insider
Your IP (Internet Protocol) address is your unique ID on the internet. It’s synonymous with your home address. Anyone in the world can contact your computer through its
IP address, and send a retrieve information with it.
I’m sure at one time or another you’ve heard that hackers can hack your computer via your IP address. This is one of the reasons proxies and anonymity services exist, to protect people from learning your IP address. So how are hackers using just an address to get into your computer and make your life hell? Open ports. Your computer runs services like media sharing on what are called ports. A port is just an opening that a service uses as a communications endpoint. There are 65, 535 total allocated ports in TCP/UDP. To exploit a service on a port, a hacker would banner grab for the software and version to scour sites like Packet Storm for exploits to run against the ‘s Null Byte is going to demonstrate a simple “port scan” on local computer using Nmap, and teach how a hacker would exploit these services, as well as how to guard ourselves against it. This will be done under Linux, but Nmap is available for all platforms. If you can’t figure out how to install it in Windows with the GUI installer (yeah, right), follow along using 1 Download & Install NmapBold words are commands that must be entered in a terminal emulator.
First, we must download Nmap, which is going to be our tool that we use for port scanning and information gathering: wget, extract the archive: tar -zxvf
Change to the newly made directory: cd This is the standard installation procedure:. /configure
make && sudo make installNmap should now be installed! Step 2 Scan for a TargetLet’s scan a local computer. I’m going to use a website as an example, rather than a local computer. This is because my firewall is absolutely crazy, and filters out scans. Don’t scan a remote computer with the intentions of doing bad deeds. This is for educational purposes by mapping out your local network:
sudo nmap -sP 192. 168. 1. 0/24That should return a list of hosts that are up for a port scan! Step 3 Scan Your Individual TargetOut of the returned list of targets, pick one that you would like to scan for services. Let’s do a full scan of all the TCP/UDP ports: sudo nmap -p 1-65535 -T4 -A -v
You should get something that looks like the following image:As you can see, this target has MANY open ports. SSH piques my interest, so let’s move on to banner grabbing to learn the software version or our choice of 4 Banner GrabbingFor this, you can use the regular ol’ telnet client. Telnet comes with Windows and most Linux distros: telnet
From this, I would learn which software version the service is running, then see if I can find a way to exploit Can I Protect Myself? Luck for all of you lovely people, I recently made a tutorial on iptables, which will filter out unwanted connections. Also, disable any unnecessary programs that connect to the internet (remote administration, media sharing, etc). Windows users, install Comodo firewall, it’s incredible and uses a simple point and click installation, and will filter ports for you. It has great default settings and it is by powtac

Can hackers exploit your IP address? – BullGuard
An IP address is like a real-world address. It identifies a PC, a laptop, smartphone, or any other device on a network. If you want to download a movie, check out a web page, or do something else on the internet the request is sent out from your computer. This is received via a server which needs to know your IP address so the content can be delivered to you.
Knowing someone else’s IP is legitimate and essential for data routing around the Internet. Your computer already knows which IP addresses data is coming from but it doesn’t show it to you. And in most cases you can’t be harmed by someone knowing your IP address.
That said if it ends up in the wrong hands your PC can be scanned and your computer probed for vulnerabilities enabling someone to gain access to your data. At the same time unsecured smart devices such as alarm systems and baby monitors can be remotely hacked via the IP address.
For most hackers however it’s easier to gain access to a computer via malware rather than attacking an IP address.
That said:
An IP address can enable hackers to potentially block you from reaching a certain website, or post content like messages or comments. You may also be blocked or banned from playing online games on gaming devices and this actually happens frequently among gamers.
Hackers can also use a combination of your IP address and details from other sources to put together data about your identity.
Hackers may also perform a Distributed Denial of Service (DDoS) attack, flooding your network with data via the IP address and overloading the network to stop normal traffic from getting through. That said this is unlikely to happen given that DDoS attacks typically target large organisations.
However, in terms of privacy the Internet is wide open and for those with even rudimentary knowledge an IP address can be used as starting point to gather so much information on an individual it can be frightening. In reality you never really know whether someone is probing your IP address to gather information or not.
We’re not suggesting that you are being monitored, not at all, but by hiding your IP address from the outside world you are not only protecting yourself but shutting a door on snoopers and reclaiming your privacy.
VPN hides your IP address
BullGuard VPN (virtual private network) is designed to help you reclaim your privacy. It hides your IP address by allowing you to connect to the Internet from another location other than yours.
When using a VPN if anybody tries to identify your IP address they can only see the IP address of the server from which you are connecting to the Internet which could be in another country, your own country or on the other side of the world.
Alongside reclaiming your privacy BullGuard VPN also has other benefits:
It encrypts your data and creates a tunnel between your device and the online services you are accessing. This makes it indispensable when using a public W-Fi network which are notoriously insecure.
Ensures hackers can’t access your data and keeps you safe from man-in-the-middle attacks in which a hackers positions between your device and the server your data is going to in order to snoop on or steal data.
Provides the flexibility to safely and securely access the Internet and online services from home, work or abroad.
Doesn’t log what you’re doing online, or keep records of the websites you visit, ensuring you have complete online privacy and security.
