NO.249 Samuel, a professional hacker, monitored and Intercepted already established traffic between Bob and a host machine to predict Bob’s ISN. Using this ISN, Samuel sent spoofed packets with Bob’s IP address to the host machine. The host machine responded with <| packet having an Incremented ISN. Consequently. Bob’s connection got hung, and Samuel was able to communicate with the host machine on behalf of Bob. What is the type of attack performed by Samuel in the above scenario?

NO.253 jane invites her friends Alice and John over for a LAN party. Alice and John access Jane’s wireless network without a password. However. Jane has a long, complex password on her router. What attack has likely occurred?

NO.254 Clark, a professional hacker, was hired by an organization to gather sensitive information about its competitors surreptitiously. Clark gathers the server IP address of the target organization using Whois footprinting. Further, he entered the server IP address as an input to an online tool to retrieve information such as the network range of the target organization and to identify the network topology and operating system used in the network.
What is the online tool employed by Clark in the above scenario?

NO.255 Richard, an attacker, aimed to hack IoT devices connected to a target network. In this process, Richard recorded the frequency required to share information between connected devices. After obtaining the frequency, he captured the original data when commands were initiated by the connected devices. Once the original data were collected, he used free tools such as URH to segregate the command sequence.
Subsequently, he started injecting the segregated command sequence on the same frequency into the IoT network, which repeats the captured signals of the devices.
What is the type of attack performed by Richard in the above scenario?

NO.259 Ethical hacker Jane Smith is attempting to perform an SQL injection attack. She wants to test the response time of a true or false response and wants to use a second command to determine whether the database will return true or false results for user IDs.
Which two SQL injection types would give her the results she is looking for?

NO.260 Susan, a software developer, wants her web API to update other applications with the latest information. For this purpose, she uses a user-defined HTTP tailback or push APIs that are raised based on trigger events: when invoked, this feature supplies data to other applications so that users can instantly receive real-time Information.
Which of the following techniques is employed by Susan?

NO.261 Bob, an attacker, has managed to access a target loT device. He employed an online tool to gather information related to the model of the loT device and the certifications granted to it. Which of the following tools did Bob employ to gather the above Information?

NO.262 Thomas, a cloud security professional, is performing security assessment on cloud services to identify any loopholes. He detects a vulnerability in a bare-metal cloud server that can enable hackers to implant malicious backdoors in its firmware. He also identified that an installed backdoor can persist even if the server is reallocated to new clients or businesses that use it as an laaS.
What is the type of cloud attack that can be performed by exploiting the vulnerability discussed in the above scenario?

NO.263 Bob, your senior colleague, has sent you a mail regarding a deal with one of the clients. You are requested to accept the offer and you oblige. After 2 days. Bob denies that he had ever sent a mail. What do you want to “”know”” to prove yourself that it was Bob who had send a mail?

NO.264 Attacker Simon targeted the communication network of an organization and disabled the security controls of NetNTLMvl by modifying the values of LMCompatibilityLevel, NTLMMinClientSec, and RestrictSendingNTLMTraffic. He then extracted all the non-network logon tokens from all the active processes to masquerade as a legitimate user to launch further attacks. What is the type of attack performed by Simon?
