What type of attack involves the hacker modifying the source IP address of the packet?
What are cyber attacks and how do you defend against them?The May 2009 ISO/IEC 27000 publication described an attack on an information or computer network as an “attempt to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of anything that has value to the organization.” ⁽¹⁾ Show
The concept of a cyber attack or a computer network attack is rooted in this description. Techopedia describes a cyber attack as a “deliberate exploitation of computer systems, technology-dependent enterprises and networks.” Techopedia continues, stating that cyber attacks use “malicious code to alter computer code, logic or data, resulting in disruptive consequences that can compromise data and lead to cybercrimes, such as information and identity theft.” ⁽²⁾ It’s not just computer networks and computer information systems that are being attacked. Cyber attacks are also infamous for attacking computer infrastructure and peoples’ personal computers. In addition to cybercrime, cyber attacks can also be associated with cyberwarfare or cyberterrorism, particularly in instances when the attackers are state actors, groups or affiliated organizations. For example, in 2014 a group hacked Sony Pictures and stole troves of data, including many Sony Pictures employees’ personal information, executive salary information, copies of unreleased films, and more. The group, which is suspected to be North Korean or affiliated with North Korea, used a Shamoon wiper malware to obliterate Sony Pictures’ computer infrastructure. What are the most common types of cyber attacks?According to long-time Netwrix blogger Jeff Melnick, the ten most common types of cyber attack consist of the following examples:
For Hypertext Transfer Protocol (HTTP) transactions, where there often is a TCP connection with a client and a server, the attacker takes advantage of any weakness in the network communication protocol. By forking the TCP connection into two connections, the attacker creates one connection between the attacker and the victim, and a second connection between the attacker and the server. By using the process known as Address Resolution Protocol (ARP) spoofing, the attacker masquerades as a proxy reading and gets the victim to direct traffic through the attacker as opposed to through the normal router.
Techopedia expands on this explanation, describing a replay attack as one where an attacker detects a data transmission, then fraudulently delays or repeats it, before retransmitting it. To further expand on this explanation, replay attacks target the security protocol with data transmission replays from a different sender into the targeted receiving system.

What type of attack involves the attacker modifying the source IP address of the packet?In an IP spoofing attack, an attacker will send IP packets from a spoofed IP address to hide their true identity. Attackers most often use IP address spoofing attacks in DoS attacks that overwhelm their target with network traffic.
What type of attack involves the attacker modifying the source IP address of the packet quizlet?Header manipulation attacks modify the data contained in Internet protocol (IP) packets. Specifically, they modify information in packet headers to bypass network security controls or probe for information about a network.
Which of the following attacks involves modifying the IP packet header and source address to make it look like they are coming from a trusted source?In IP spoofing, a hacker uses tools to modify the source address in the packet header to make the receiving computer system think the packet is from a trusted source, such as another computer on a legitimate network, and accept it.
What kind of attack is an example of IP spoofing quizlet?IP Address spoofing - process of creating IP packets with forged source IP address to impersonate legitimate system. This kind of spoofing is often used in DoS attacks (Smurf Attack). What is ARP Spoofing?
