Users have started to come across more and more malicious links, which bring a different kind of destruction to your computer after clicking. In this case, users need to know what this malware looks like, its links, and other things that can harm them. In this article, we will familiarize ourselves with sniffing and spoofing, find their difference, consider the protection measures from this and disassemble and type.
What is Sniffing?
Sniffing is a way to monitor the data packet and records through the network. System or network administrators fix problems with sniffers for monitoring. However, sniffing is convenient for hackers in its way. With sniffing, they intercept sensitive data packets, including account information or passwords. Cybercriminals install sniffers in the system like software.
Types of Sniffing Attacks
To fight the attack, we need to understand what it is, where it came from, how it is, and how we warm ourselves against it. So below, we’ll look at some types of sniffing to make it clear what it is and what it looks like:
📌 Active Sniffing
If you know what a switch is, you will find it easier to understand this sniffing. Because active sniffing is sniffing in the switch, the switch’s job is to track MAC port addresses, ensuring data transfer to a specific destination. Interceptors actively inject traffic into the local network to intercept traffic between targets. There is more than one way to do this.
📌 Passive Sniffing
Passive sniffing is listening through the hub. Traffic is visible to all machines in the network segment through which it passes. All traffic runs on the network link layer. In this way, the hacker sends a network packet over the network network network and thus reaches the machine that is connected to this network packet.
Active sniffing with address resolution protocols infects the address memory tables of the switch’s content. Then, an intruder intercepts data from the switch to redirect legitimate traffic to another port. Other sniffing methods include spoofing, DNS, and DHCP.
What is Spoofing?
Spoofing is a type of cybercrime whose method is to impersonate another computer or network in the form of an ordinary user to convince the user of the reliability of the source of information. Hackers use this method as a variant of hacking an operating system to steal sensitive data, abuse a captured computer, launch attacks such as DDoS (Denial of Service), and others.
Different Types of Spoofing Attacks
There are different kinds of spoofing (GPS spoofing, website spoofing, IP spoofing, etc) each making their attacks in different directions. You may think you can only make attacks and hacks through a web browser or pop-up windows, but no. Below we will tell you about the most common types of spoofing:
- Caller ID Spoofing. Intruders use spoofing the caller ID so that they can not block the number. They take other people’s numbers; they use alien city codes to disguise themselves. They use voice protocol on the Internet. All this is to get important information from the recipient of this call after the recipient picks up the phone.
- Email Spoofing. Through this method, attackers attempt to steal your confidential data, harm your computer or put malicious software on it. These are disguised emails. The sender’s address bar may seem familiar to you; it is done to deceive you as if the letters were legal. Be careful. In this case, we will use alternative letters or numbers in the sender’s address bar.
- Website Spoofing. Intruders disguise a dangerous website as a legitimate website. They use similar colors and the shape of company logos to do this. The addresses of these sites are also fake, although they may be identical to legal ones. Of course, the primary purpose of this is to harm the user. When you visit such a site, it turns out to be malicious, endangering your computer and its data.
- DNS Server Spoofing. This method redirects traffic to a different IP address. In this case, it occurs at the DNS protocol level. DNS (Domain Name Server) spoofing or DNS cache poisoning is a type of cyberattack used by an attacker to direct the victim’s traffic to a malicious website (instead of a legitimate IP address).
- GPS Spoofing. It’s easy to fool GPS receivers; Fake signals resemble accurate signals. It is done to divert planes, ships, and other vehicles and redirects them to different addresses.
- ARP Spoofing. It is a method of manipulation to capture sessions and steal personal data. The ultimate goal is to access the data of this address’s owner. ARP (Address Resolution Protocol) spoofing is a type of cyberattack that relies on attackers sending malicious ARP packets to a default gateway over a local area network (LAN), using it to associate their own MAC address with an IP address. gateway devise.
- Man-in-the-Middle (MitM) attack. They are also known as the attack type «man in the middle» (MITM). In these attacks, the attacker intercepts communication between two users. Thus, the attacker can deceive the victim by revealing confidential information by «substitution» of the identity of the original sender, whom the recipient supposedly trusts.
- Text Message Spoofing. The method of sending a text message via the wrong phone number. These text messages send links through which the user can get malicious and phishing downloads. Protect yourself and your mobile phone data using security.
- Extension Spoofing. The attacker changes the file extension and masks malware under the test file. After running this text file on your device, the malware gets on your device.
Difference Between Sniffing and Spoofing
After all, let us consider the difference between sniffing and spoofing. Sniffing collects data packets, analyzes network traffic, and sends those packets to the targeted traffic. Spoofing is the theft of the user’s data. After that, it distributes malware, and phishing attacks make all sorts of data theft thanks to this data. Spoofing is when an attacker uses a foreign IP address and creates a TCP/IP. Sniffing, in turn, the attacker (the program) swindles between two packet transfer points and deceives the system by pretending to be one of those points, tracking and thus stealing the data sent between two points.
Protection Against Sniffing and Spoofing
Every day, cybercriminals develop more and more different malware for attacks. Below we will consider some of the most common items for protection:
- Provide packet filtering
- Authenticate systems and users
- Use software to detect spoofing
- Verify the authenticity of the sources
After everything you read, you probably now think about how to do any actions online.
