IP spoofing is when a hacker changes an original IP address for the purpose of hiding the true source IP address. It can be used to attack:
- Individual users
It’s a type of cyber-attack used by hackers to access computers. Once they have gained entry, the attacker can access stored sensitive data and utilise the computer system for malicious use, such as incorporating it into a botnet for Distributed Denial of Service (DDoS) attacks.
How to Detect IP Spoofing?
IP spoofing is detected by analysing the packet headers of data packets to look for discrepancies. The IP address can be validated by its MAC (Media Access Control) address, or through a security system such as Cisco’s IOS NetFlow, which assigns an ID and timestamp to each computer that logs onto the network.
Is IP Spoofing Illegal?
IP spoofing is illegal in many countries. A variety of government agencies, including the FBI and NSA, monitor traffic as a means to identify potential threats against computer systems. This includes any forged packets or other efforts to disguise IP addresses.
Some forms of IP spoofing are legal; for example it may be used by network administrators when troubleshooting an issue on their own machine without logging onto that system remotely. However, this is not generally recommended practice because it could potentially expose sensitive data if hackers were somehow able to access your internal networks from within your organisation’s firewall/router equipment (e.g. through vulnerabilities).
How Can Hackers Benefit From IP Spoofing?
Hackers use random spoofed source IP addresses in order to conceal their own identity and make the attack harder to block. It then looks like it is originating from many sources. they use spoofed IPs to build enormous botnets and run DDoS attacks.
These hackers can spoof a trusted IP and get into your computer network. Once they are in the network they can freely delve into what’s inside.
They can access sensitive data and use your computer network for malicious purposes.
