The process through which an illegitimate website pretends to be a specific legitimate website is known as Spoofing. Spoofing:Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server. Spoofing can be used to gain access to a targets personal information, spread malware through infected links or attachments, bypass network access controls, or redistribute traffic to conduct a denial-of-service attack. Spoofing is often the way a bad actor gains access in order to execute a larger cyber attack such as an advanced persistent threat or a man-in-the-middle attack. 1. Sniffing:Sniffing is the process of monitoring and capturing all data packets that are passing through a computer network using packet sniffers. Packet Sniffers are used by network administrators to keep track of data traffic passing through their network. These are called network protocol analyzers. In the same way, malicious attackers employ the use of these packet sniffing tools to capture data packets in a network. 2. Back DoorsIn the world of cybersecurity, a backdoor refers to any method by which authorized and unauthorized users are able to get around normal security measures and gain high-level user access (aka root access) on a computer system, network, or software application. Once they're in, cybercriminals can use a backdoor to steal personal and financial data, install additional malware, and hijack devices. 3. War Dialing:War dialing refers to the use of various kinds of technology to automatically dial many phone numbers, usually in order to find weak spots in an IT security architecture. Hackers often use war dialing software, sometimes called "war dialers" or "demon dialers," to look for unprotected modems.
