IP Spoofing: How to Protect Your IP from Spoofing

When you are online, your IP address remains a significant detail of your online identity. It can also be revealed or stolen through vulnerabilities in the Internet Protocol (IP). In such a case, your private information can be stolen as well. Moreover, your traffic can be fully intercepted. It means the hackers will be able to steal your sensitive information. Even the worst situation can occur. Hackers can use your online identity information to commit various cybercrimes. This particular IP stealing attack is called IP spoofing. You need to learn more about IP spoofing to be able to protect yourself. It is better to prevent your IP stealing than to deal with the unpleasant consequences.

IP Spoofing Definition – How to Protect Yourself

The best way to protect yourself from cyberattacks is to be prepared. You need to learn first what IP spoofing is. IP spoofing is a situation when hackers change the IP address of a data package to a fake one, launching an IP spoofing attack. They choose to make a fake address appear like a valid one. Hackers can use another strategy as well. They can simply mask the receiver’s IP address in its place. What makes the hackers’ actions with IP address faking possible on the Internet?

Mechanism of Data Transfer Through TCP/IP Protocols

When you send or receive information online, your traffic is always divided into small IP packets of data. Every particular packet is sent separately. Once reaching their destination, all the packets are gathered by the receiver’s device or in some cases, by websites’ servers. Every sent packet of information has a peculiar IP header with the exact IP address of the source and the receiver. TCP/IP protocols transfer the packets in normal circumstances.

Still, such protocols have weak points. There is a three-way TCP handshake you should pay attention to when sending or receiving information. In short, the three-step transferring includes the following directions:

• First, a SYN message is sent to the receiver by the source. This assures the synchronization of sequence numbers between two parties.
• Next, the receiver sends an ACK message – it is a confirmation of receiving the SYN message.
• Finally, the SYN-ACK message is sent by the source to the receiver, and a secure connection is confirmed.

How IP Spoofing Operates – IP Header Details

IP spoofing is an illegal attack. The hackers intercept the TCP handshake before the final step before the source sends the SYN-ACK message. They sent a fake confirmation with their devices’ MAC address and a changed source address. In the end, the receiver is sure of getting data from a legitimate source. They do not understand that the data is sent not from an original sender. Even being exposed to the cyber-attack, they do not see any signs of dealing with the fake spoofed IP address.

Types of IP Spoofing Attacks

IP spoofing attacks can be categorized into several types, each with its own unique characteristics and goals. Understanding these types can help you better protect your systems and networks from potential threats. Here are some of the most common types of IP spoofing attacks:

• Denial of Service (DoS) Attacks: In a DoS attack, the attacker overwhelms a target system with a massive amount of traffic from spoofed IP addresses. This flood of traffic makes it difficult for the system to distinguish between legitimate and malicious requests, often leading to system crashes or severe slowdowns.
• Distributed Denial of Service (DDoS) Attacks: Similar to DoS attacks, DDoS attacks involve multiple compromised devices working together to launch a coordinated attack on a target system. The use of multiple devices makes it even more challenging to defend against, as the traffic appears to come from numerous sources.
• Man-in-the-Middle (MitM) Attacks: In MitM attacks, the attacker intercepts and alters communications between two parties by spoofing the IP address of one of the parties. This allows the attacker to eavesdrop on the communication, steal sensitive information, or inject malicious data.
• IP Spoofing for Unauthorized Access: Attackers use spoofed IP addresses to gain unauthorized access to systems or networks by impersonating a trusted host. This type of attack can lead to data breaches, unauthorized data manipulation, and other malicious activities.

Key Dangers of IP Spoofing Attacks

Hackers can cause lots of problems when they create bogus IP addresses. The destination IP address is crucial for routing packets over the Internet, and its manipulation can lead to severe security breaches. They know numerous ways to use spoofing for quite malicious purposes. It is easy for them to attack individuals, applications, or servers. The following are the top malicious uses of IP spoofing by hackers.

Firewall and IP Authorization Bypassing

Hackers often come up with IP address spoofing to bypass certain security measures. They often try to bypass firewalls that contain their original address in the blacklist. It means, even if the attacker’s real address is blocked, with spoofed fake IP addresses, they gain access to needed servers and applications. They also reach numerous servers that allow only “reliable” IP addresses. Experienced hackers can use a spoofed IP to get into your computer. Once they access your computer, they can do what they like. Thus, your entire information and identifications can be compromised. This is the reason why companies should forget about relying on IP authorization. They should use more advanced methods of authentication.

Denial of Service (DDoS) Attacks

During the Denial of Service (DoS)/Distributed Denial of Service (DDoS), the attacked website or server faces a crushing amount of fake requests. Inspecting both source and destination IP addresses is crucial in identifying and blocking potentially harmful traffic during such attacks. As a result, the website or server is brought down. Often, the infected devices sent this huge suspicious amount of fake requests. Mostly, botnet worms infect the mentioned devices. Hackers can send out millions of fake requests to the server and spoofs the IP address once the servers send responses to the victim’s device. Thus, practically anyone can get your IP address which can lead to bad consequences.

Man-in-the-middle (MITM)

These are quite popular attacks. Especially when users deal with the public or other unsecured Wi-Fi connections, the hackers can intercept your communications and gain access to your sensitive private information. The hacker’s device can be set between the server and the victim’s device, using a spoof IP address to intercept communications. Thus, the information you share when on an unsecured Wi-Fi connection is never safe. Even if some of your private data is intercepted, hackers can try to break into your accounts. In such a case, VPN can be the best solution. The VeePN is a special protection tool that allows preventing hackers’ attacks when on unsecured Wi-Fi.

Detecting Spoofed IP Addresses

Detecting spoofed IP addresses can be challenging, but several techniques can help identify and prevent IP spoofing attacks. Here are some effective methods:

• Packet Filtering: This technique involves examining incoming packets and filtering out those that appear to be coming from spoofed IP addresses. By analyzing the packet headers and comparing them to known legitimate IP addresses, you can identify and block suspicious traffic.
• Ingress Filtering: Ingress filtering involves filtering incoming packets at the network perimeter to prevent spoofed packets from entering the network. This method helps ensure that only legitimate traffic reaches your internal network.
• Egress Filtering: Egress filtering focuses on filtering outgoing packets to prevent spoofed packets from leaving the network. This technique helps protect other networks from potential spoofing attacks originating from your network.
• IP Address Verification: Verifying the IP address of incoming packets can help ensure that they are legitimate. This can be done by cross-referencing the source IP address with a list of known trusted IP addresses or by using more advanced verification methods.

Essential Tools for IP Spoofing Detection

Several tools can help detect and prevent IP spoofing attacks. Here are some of the most effective ones:

• Firewalls: Firewalls can be configured to filter out incoming packets that appear to be coming from spoofed IP addresses. By setting up rules and policies, firewalls can block suspicious traffic and protect your network from potential attacks.
• Intrusion Detection Systems (IDS): IDS systems monitor network traffic for signs of potential IP spoofing attacks. They can detect unusual patterns and alert administrators to take action, helping to prevent attacks before they cause significant damage.
• IP Address Tracking Software: This software tracks and monitors IP addresses to detect and prevent IP spoofing attacks. By keeping an eye on IP address activity, you can identify suspicious behavior and take steps to mitigate potential threats.
• Network Monitoring Tools: These tools monitor network traffic in real-time, allowing you to detect potential IP spoofing attacks as they happen. By analyzing traffic patterns and identifying anomalies, network monitoring tools can help you respond quickly to potential threats.

IP Spoofing – Legal Matters and Prevention

IP spoofing is not illegal when you are not aimed at using a fake IP address for malicious purposes, such as an IP spoofing attack. In fact, you can change your IP address once using VPN. It is completely legal. Often, websites create fake users to reform certain online tests. Still, IP spoofing is completely illegal when someone fakes his identity and tries to proceed with cybercrimes.

To prevent yourself from IP spoofing negative consequences, you should check the following methods of protection:

• Constantly monitor networks for unusual activity;
• Use advanced authentication and verification methods;
• Check your firewall and place the sensitive assets behind it;
