Your IP address may look like a long number row, but to a hacker, it can be an instrument of evil activity. While your exposure to an IP doesn't pose an immediate danger per se, it is thus important to understand what a hacker can do with it. Let's break down how cybercriminals can exploit an IP and how you can keep it safe.
Determining Your Broad Area of Location
The very first thing a hacker will easily know once he has obtained your IP address is your general area of location. He can find out your city or region using even simple online tools such as IP tracking websites. Of course, he won't pinpoint the street number but can already pinpoint your general area or location which may trigger other related hacking attempts such as phishing attacks. Hackers would use your address and ISP to dupe you through social engineering.
IP Spoofing: Identity Mimicry Online
The hacker can manipulate the IP addresses and make it seem like the actions they are performing are coming from your device. In this method, which is known as IP spoofing, hackers perpetrate various illegal activities while concealing identities. Many people employ IP spoofing in DDoS attacks whereby hackers inject tremendous amounts of traffic into a network to actually shut it down. Using your IP address during this attack may keep them undetected while they wreck the damage.
Selling Your IP Address
One seems minute, but hackers sell bundles of thousands of IP addresses in bulk across the dark web, and those addresses can be used in large-scale social engineering projects that lead to data theft. Used with other personal data, your IP address can be a wonderful commodity in some hacker's arsenal, allowing them to crack into almost any online account.
Scanning for Further Information
Using this method, and with the use of such tools as Nmap, hackers can not only obtain your IP but also uncover which OS your machine is running, applications that are installed, and open ports. If vulnerabilities exist in your system, they can launch specific attacks on those particular weaknesses, which will then allow them to get into your network, and even control your devices.
A DDoS attack
Although it is seldom that DDoS attacks any user, hackers can use your IP to attack you using DDoS, which will turn your device into a traffic flooder and take it offline. Such attacks are usually employed in larger organisations, although those engaging in activities such as online gaming and other competitive activities are also at risk. For instance, some players have used DDoS attacks to cut off their opponents' internet.
How to Hide Your IP Address
The likelihood that someone actually targeted you may be low, but this is equally as important to adhere to these safety precaution guidelines. With a virtual private network or a proxy server, your public IP address remains hidden, which makes it extremely hard for hackers to find and take advantage of it. It can also protect your devices by updating them as regularly as possible and using firewalls.
It is important to note that knowing an IP address doesn't give hackers total control over your system. However, it can be part of a scheme that encourages them to come closer to extracting more personal information or conducting attacks. However, usually there's little chance that someone would go out of his way to harm you using just your IP address; still, you can never be too safe. Securing the network and masking the IP simply reduces these risks from IP-based attacks.
Care needs to be taken, and preventative measures need to be in place so that nobody would use those malpractices against you.
