Josh has finished scanning a network and has discovered multiple vulnerable services. He knows that several of these usually have protections against external sources but are frequently susceptible to internal users. He decides to draft an email, spoof the sender as the internal IT team, and attach a malicious file disguised as a financial spreadsheet. Before Josh sends the email, he decides to investigate other methods of getting the file onto the system. For this particular attempt, what was the last stage of the cyber kill chain that Josh performed? Weaponization Exploitation Reconnaissance Delivery

Geena, a cloud architect, uses a master component in the Kubernetes cluster architecture that scans newly generated pods and allocates a node to them. This component can also assign nodes based on factors such as the overall resource requirement, data locality, software/hardware/policy restrictions, and internal workload interventions. Which of the following master components is explained in the above scenario? Kube-scheduler Kube-controller-manager Etcd cluster Kube-apiserver

Kube-scheduler

Ricardo has discovered the username for an application in his target's environment. As he has a limited amount of time, he decides to attempt to use a list of common passwords he found on the Internet. He compiles them into a list and then feeds that list as an argument into his password-cracking application. What type of attack is Ricardo performing?

Bob wants to ensure that Alice can check whether his message has been tampered with. He creates a checksum of the message and encrypts it using asymmetric cryptography. What key does Bob use to encrypt the checksum for accomplishing this goal? His own public key His own private key Alice’s private key Alice’s public key

Alice’s public key

Dayn, an attacker, wanted to detect if any honeypots are installed in a target network. For this purpose, he used a time-based TCP fingerprinting method to validate the response to a normal computer and the response of a honeypot to a manual SYN request.Which of the following techniques is employed by Dayn to detect honeypots? Detecting the presence of Honeyd honeypots Detecting the presence of Sebek-based honeypots Detecting the presence of Snort_inline honeypots Detecting honeypots running on VMware

Detecting the presence of Honeyd honeypots

A group of hackers were roaming around a bank office building in a city, driving a luxury car. They were using hacking tools on their laptop with the intention to find a free- access wireless network. What is this hacking process known as? Spectrum analysis Wardriving GPS mapping Wireless sniffing

Henry is a penetration tester who works for XYZ organization. While performing enumeration on a client organization, he queries the DNS server for a specific cached DNS record. Further, by using this cached record, he determines the sites recently visited by the organization’s user. What is the enumeration technique used by Henry on the organization? DNS zone walking DNS cache snooping DNS cache poisoning DNSSEC zone walking

DNS cache snooping

Miley, a professional hacker, decided to attack a target organization’s network. To perform the attack, she used a tool to send fake ARP messages over the target network to link her MAC address with the target system’s IP address. By performing this, Miley received messages directed to the victim’s MAC address and further used the tool to intercept, steal, modify, and block sensitive communication to the target system. What is the tool employed by Miley to perform the above attack? Wireshark BetterCAP DerpNSpoof Gobbler

BetterCAP

Gregory, a professional penetration tester working at Sys Security Ltd., is tasked with performing a security test of web applications used in the company. For this purpose, Gregory uses a tool to test for any security loopholes by hijacking a session between a client and server. This tool has a feature of intercepting proxy that can be used to inspect and modify the traffic between the browser and target application. This tool can also perform customized attacks and can be used to test the randomness of session tokens. Which of the following tools is used by Gregory in the above scenario? Burp Suite Nmap CxSAST Wireshark
