Which attack uses the users Web browser settings to impersonate the user?
There are many types of security threats that attackers can use to exploit insecure applications. Threat actors can run some of these attacks using automated software, while others require a more active role from attackers. In this tutorial, we will explain the basic idea behind a man-in-the-middle (MITM) attack, providing examples and mitigation techniques. Show
What Is a Man-in-the-Middle Attack?A man-in-the-middle attack is a type of eavesdropping attack, where attackers interrupt an existing conversation or data transfer. After inserting themselves in the "middle" of the transfer, the attackers pretend to be both legitimate participants. This enables an attacker to intercept information and data from either party while also sending malicious links or other information to both legitimate participants in a way that might not be detected until it is too late. You can think of this type of attack as similar to the game of telephone where one person's words are carried along from participant to participant until it has changed by the time it reaches the final person. In a man-in-the-middle attack, the middle participant manipulates the conversation unknown to either of the two legitimate participants, acting to retrieve confidential information and otherwise cause damage. Common abbreviations for a man-in-the-middle attack including MITM, MitM, MiM, and MIM. Key Concepts of a Man-in-the-Middle AttackMan-in-the-middle attacks:

State of Software Security v12Read the ReportExamples of MITM AttacksAlthough the central concept of intercepting an ongoing transfer remains the same, there are several different ways attackers can implement a man-in-the-middle attack. Scenario 1: Intercepting Data
In this scenario, an attacker intercepts a data transfer between a client and server. By tricking the client into believing it is still communicating with the server and the server into believing it is still receiving information from the client, the attacker is able to intercept data from both as well as inject their own false information into any future transfers. Scenario 2: Gaining Access to Funds
In this scenario, the attacker intercepts a conversation, passing along parts of the discussion to both legitimate participants. Real-World MITM AttacksIn 2011, Dutch registrar site DigiNotar was breached, which enabled a threat actor to gain access to 500 certificates for websites like Google, Skype, and others. Access to these certificates allowed the attacker to pose as legitimate websites in a MITM attack, stealing users' data after tricking them into entering passwords on malicious mirror sites. DigiNotar ultimately filed for bankruptcy as a result of the breach. In 2017, credit score company Equifax removed its apps from Google and Apple after a breach resulted in the leak of personal data. A researcher found that the app did not consistently use HTTPS, allowing attackers to intercept data as users accessed their accounts. Interactions Susceptible to MITM AttacksAny improperly secured interaction between two parties, whether it's a data transfer between a client and server or a communication between two individuals over an internet messaging system, can be targeted by man-in-the-middle attacks. Logins and authentication at financial sites, connections that should be secured by public or private keys, and any other situation where an ongoing transaction could grant an attacker access to confidential information are all susceptible.

What is the difference between a DoS and a DDoS attack?A denial-of-service (DoS) attack overloads a server with traffic, thereby shutting it down. A distributed denial-of-service (DDoS) attack is a DoS attack in which numerous computers or machines flood a targeted resource.
Which attack intercepts communications between a Web browser?A man-in-the-middle (MiTM) attack is a type of cyber attack in which the attacker secretly intercepts and relays messages between two parties who believe they are communicating directly with each other. The attack is a type of eavesdropping in which the attacker intercepts and then controls the entire conversation.
Which of the following attacks intercepts communication between a Web browser and the machine that hosts it?Basically, Web Injects is an Man-in-the-Browser (MitB) attack in which malware intercepts communication on the channel between a browser and a web server. The malware manipulates the communication channel to and from the browser—most commonly on the response.
What is the difference between a DDoS attack and a DoS attack quizlet?The term denial of service (DoS) is a generic term that includes many types of attacks. In a DoS attack, a single attacker directs an attack at a single target, sending packets directly to the target. In a distributed DoS attack (DDoS), multiple PCs attack a victim simultaneously.
