NEW QUESTION # 252
A company's Web development team has become aware of a certain type of security vulnerability in their Web software. To mitigate the possibility of this vulnerability being exploited, the team wants to modify the software requirements to disallow users from entering HTML as input into their Web application.
What kind of Web application vulnerability likely exists in their software?

• A. Gross-site Request Forgery vulnerability
• B. Web site defacement vulnerability
• C. SQL injection vulnerability
• D. Cross-site scripting vulnerability

Answer: D

Explanation:
There is no single, standardized classification of cross-site scripting flaws, but most experts distinguish between at least two primary flavors of XSS flaws: non-persistent and persistent. In this issue, we consider the non-persistent cross-site scripting vulnerability.
The non-persistent (or reflected) cross-site scripting vulnerability is by far the most basic type of web vulnerability. These holes show up when the data provided by a web client, most commonly in HTTP query parameters (e.g. HTML form submission), is used immediately by server-side scripts to parse and display a page of results for and to that user, without properly sanitizing the content.
Because HTML documents have a flat, serial structure that mixes control statements, formatting, and the actual content, any non-validated user-supplied data included in the resulting page without proper HTML encoding, may lead to markup injection. A classic example of a potential vector is a site search engine: if one searches for a string, the search string will typically be redisplayed verbatim on the result page to indicate what was searched for. If this response does not properly escape or reject HTML control characters, a cross-site scripting flaw will ensue.

NEW QUESTION # 253
Which iOS jailbreaking technique patches the kernel during the device boot so that it becomes jailbroken after each successive reboot?

• A. Untethered jailbreaking
• B. Semi-tethered jailbreaking
• C. Semi-Untethered jailbreaking
• D. Tethered jailbreaking

Answer: A

Explanation:
An untethered jailbreak is one that allows a telephone to finish a boot cycle when being pwned with none interruption to jailbreak-oriented practicality.
Untethered jailbreaks area unit the foremost sought-after of all, however they're additionally the foremost difficult to attain due to the powerful exploits and organic process talent they need. associate unbound jailbreak is sent over a physical USB cable association to a laptop or directly on the device itself by approach of associate application-based exploit, like a web site in campaign.
Upon running associate unbound jailbreak, you'll be able to flip your pwned telephone off and on once more while not running the jailbreak tool once more. all of your jailbreak tweaks and apps would then continue in operation with none user intervention necessary.
It's been an extended time since IOS has gotten the unbound jailbreak treatment. the foremost recent example was the computer-based Pangu break, that supported most handsets that ran IOS nine.1. We've additionally witnessed associate unbound jailbreak within the kind of JailbreakMe, that allowed users to pwn their handsets directly from the mobile campaign applications programme while not a laptop.

NEW QUESTION # 256
An IT company has just implemented new security controls to their network and system setup. As a Certified Ethical Hacker, your responsibility is to assess the possible vulnerabilities in the new setup. You are given the information that the network and system are adequately patched with the latest updates, and all employees have gone through recent cybersecurity awareness training. Considering the potential vulnerability sources, what is the best initial approach to vulnerability assessment?

• A. Checking for hardware and software misconfigurations to identify any possible loopholes
• B. Conducting social engineering tests to check if employees can be tricked into revealing sensitive information
• C. Evaluating the network for inherent technology weaknesses prone to specific types of attacks
• D. Investigating if any ex-employees still have access to the company's system and data

Answer: A

Explanation:
A vulnerability assessment is a systematic review of security weaknesses in an information system. It evaluates if the system is susceptible to any known vulnerabilities, assigns severity levels to those vulnerabilities, and recommends remediation or mitigation, if and whenever needed1. A vulnerability assessment can be performed using various tools and techniques, depending on the scope and objectives of the assessment.
Considering the potential vulnerability sources, the best initial approach to vulnerability assessment is to check for hardware and software misconfigurations to identify any possible loopholes. Hardware and software misconfigurations are common sources of vulnerabilities that can expose the system to unauthorized access, data breaches, or service disruptions. Hardware and software misconfigurations can include:
* Insecure default settings, such as weak passwords, open ports, unnecessary services, or verbose error messages.
* Improper access control policies, such as granting excessive privileges, allowing anonymous access, or failing to revoke access for terminated users.
* Lack of encryption or authentication mechanisms, such as using plain text protocols, storing sensitive data in clear text, or transmitting data without verifying the identity of the sender or receiver.
* Outdated or incompatible software versions, such as using unsupported or deprecated software, failing to apply security patches, or having software conflicts or dependencies.
Checking for hardware and software misconfigurations can help identify any possible loopholes that could be exploited by attackers to compromise the system or the data. Checking for hardware and software misconfigurations can be done using various tools, such as:
* Configuration management tools, such as Ansible, Puppet, or Chef, that can automate the deployment and maintenance of consistent and secure configurations across the system.
* Configuration auditing tools, such as Nipper, Lynis, or OpenSCAP, that can scan the system for deviations from the desired or expected configurations and report any issues or vulnerabilities.
* Configuration testing tools, such as Inspec, Serverspec, or Testinfra, that can verify the system's compliance with the specified configuration rules and standards.
Therefore, checking for hardware and software misconfigurations is the best initial approach to vulnerability assessment, as it can help identify and eliminate any possible loopholes that could pose a security risk to the system or the data.

NEW QUESTION # 257
User A is writing a sensitive email message to user B outside the local network. User A has chosen to use PKI to secure his message and ensure only user B can read the sensitive email. At what layer of the OSI layer does the encryption and decryption of the message take place?

• A. Application
• B. Presentation
• C. Session
• D. Transport

Answer: B

Explanation:
https://en.wikipedia.org/wiki/Presentation_layer
In the seven-layer OSI model of computer networking, the presentation layer is layer 6 and serves as the data translator for the network. It is sometimes called the syntax layer. The presentation layer is responsible for the formatting and delivery of information to the application layer for further processing or display.
Encryption is typically done at this level too, although it can be done on the application, session, transport, or network layers, each having its own advantages and disadvantages. Decryption is also handled at the presentation layer. For example, when logging on to bank account sites the presentation layer will decrypt the data as it is received.

NEW QUESTION # 260
Attacker Lauren has gained the credentials of an organization's internal server system, and she was often logging in during irregular times to monitor the network activities. The organization was skeptical about the login times and appointed security professional Robert to determine the issue. Robert analyzed the compromised device to find incident details such as the type of attack, its severity, target, impact, method of propagation, and vulnerabilities exploited. What is the incident handling and response (IH&R) phase, in which Robert has determined these issues?

• A. Preparation
• B. Incident recording and assignment
• C. Eradication
• D. Incident triage

Answer: D

Explanation:
Triage is that the initial post-detection incident response method any responder can execute to open an event or false positive. Structuring an efficient and correct triage method can reduce analyst fatigue, reduce time to reply to and right incidents, and ensure that solely valid alerts are promoted to "investigation or incident" status.
Every part of the triage method should be performed with urgency, as each second counts once in the inside of a crisis. However, triage responders face the intense challenge of filtering an unwieldy input supply into a condensed trickle of events. Here are some suggestions for expediting analysis before knowledge is validated:
Organization: reduce redundant analysis by developing a workflow that may assign tasks to responders. Avoid sharing an email box or email alias between multiple responders. Instead use a workflow tool, like those in security orchestration, automation, and response (SOAR) solutions, to assign tasks. Implement a method to re-assign or reject tasks that are out of scope for triage.
Correlation: Use a tool like a security info and even management (SIEM) to mix similar events. Link potentially connected events into one useful event.
Data Enrichment: automate common queries your responders perform daily, like reverse DNS lookups, threat intelligence lookups, and IP/domain mapping. Add this knowledge to the event record or make it simply accessible.
Moving full speed ahead is that the thanks to get through the initial sorting method however a a lot of detailed, measured approach is necessary throughout event verification. Presenting a robust case to be accurately evaluated by your security operations center (SOC) or cyber incident response team (CIRT) analysts is key. Here are many tips for the verification:
Adjacent Data: Check the data adjacent to the event. for example, if an end has a virus signature hit, look to visualize if there's proof the virus is running before career for more response metrics.
Intelligence Review: understand the context around the intelligence. simply because an ip address was flagged as a part of a botnet last week doesn't mean it still is an element of a botnet today.
Initial Priority: Align with operational incident priorities and classify incidents appropriately. ensure the right level of effort is applied to every incident.
Cross Analysis: look for and analyze potentially shared keys, like science addresses or domain names, across multiple knowledge sources for higher knowledge acurity.

NEW QUESTION # 261
John, a professional hacker, performs a network attack on a renowned organization and gains unauthorized access to the target network. He remains in the network without being detected for a long time and obtains sensitive information without sabotaging the organization. Which of the following attack techniques is used by John?

• A. Advanced persistent theft
• B. Spear-phishing sites
• C. insider threat
• D. threat Diversion theft

Answer: A

Explanation:
An advanced persistent threat (APT) may be a broad term wont to describe AN attack campaign within which an intruder, or team of intruders, establishes a bootleg, long presence on a network so as to mine sensitive knowledge.
The targets of those assaults, that square measure terribly fastidiously chosen and researched, usually embrace massive enterprises or governmental networks. the implications of such intrusions square measure huge, and include:
* Intellectual property thieving (e.g., trade secrets or patents)
* Compromised sensitive info (e.g., worker and user personal data)
* The sabotaging of essential structure infrastructures (e.g., information deletion)
* Total website takeovers
Executing an APT assault needs additional resources than a regular internet application attack. The perpetrators square measure typically groups of intimate cybercriminals having substantial resource. Some APT attacks square measure government-funded and used as cyber warfare weapons.
APT attacks dissent from ancient internet application threats, in that:
* They're considerably additional advanced.
* They're not hit and run attacks-once a network is infiltrated, the culprit remains so as to realize the maximum amount info as potential.
* They're manually dead (not automated) against a selected mark and indiscriminately launched against an outsized pool of targets.
* They typically aim to infiltrate a complete network, as opposition one specific half.
More common attacks, like remote file inclusion (RFI), SQL injection and cross-site scripting (XSS), square measure oftentimes employed by perpetrators to ascertain a footing in a very targeted network. Next, Trojans and backdoor shells square measure typically wont to expand that foothold and make a persistent presence inside the targeted perimeter.

NEW QUESTION # 262
When configuring wireless on his home router, Javik disables SSID broadcast. He leaves authentication "open" but sets the SSID to a 32-character string of random letters and numbers.
What is an accurate assessment of this scenario from a security perspective?

• A. Javik's router is still vulnerable to wireless hacking attempts because the SSID broadcast setting can be enabled using a specially crafted packet sent to the hardware address of the access point.
• B. Disabling SSID broadcast prevents 802.11 beacons from being transmitted from the access point, resulting in a valid setup leveraging "security through obscurity".
• C. It is still possible for a hacker to connect to the network after sniffing the SSID from a successful wireless association.
• D. Since the SSID is required in order to connect, the 32-character string is sufficient to prevent brute-force attacks.

NEW QUESTION # 263
Johnson, an attacker, performed online research for the contact details of reputed cybersecurity firms. He found the contact number of sibertech.org and dialed the number, claiming himself to represent a technical support team from a vendor. He warned that a specific server is about to be compromised and requested sibertech.org to follow the provided instructions. Consequently, he prompted the victim to execute unusual commands and install malicious files, which were then used to collect and pass critical Information to Johnson's machine. What is the social engineering technique Steve employed in the above scenario?

• A. Diversion theft
• B. Quid pro quo
• C. Elicitation
• D. Phishing

Answer: B

Explanation:
https://www.eccouncil.org/what-is-social-engineering/
This Social Engineering scam involves an exchange of information that can benefit both the victim and the trickster. Scammers would make the prey believe that a fair exchange will be present between both sides, but in reality, only the fraudster stands to benefit, leaving the victim hanging on to nothing. An example of a Quid Pro Quo is a scammer pretending to be an IT support technician. The con artist asks for the login credentials of the company's computer saying that the company is going to receive technical support in return. Once the victim has provided the credentials, the scammer now has control over the company's computer and may possibly load malware or steal personal information that can be a motive to commit identity theft.
"A quid pro quo attack (aka something for something" attack) is a variant of baiting. Instead of baiting a target with the promise of a good, a quid pro quo attack promises a service or a benefit based on the execution of a specific action."

NEW QUESTION # 265
Which Metasploit Framework tool can help penetration tester for evading Anti-virus Systems?

• A. msfcli
• B. msfd
• C. msfpayload
• D. msfencode

Answer: D

Explanation:
https://www.offensive-security.com/metasploit-unleashed/msfencode/
One of the best ways to avoid being stopped by antivirus software is to encode our payload with msfencode. Msfencode is a useful tool that alters the code in an executable so that it looks different to antivirus software but will still run the same way. Much as the binary attachment in email is encoded in Base64, msfencode encodes the original executable in a new binary. Then, when the executable is run, msfencode decodes the original code into memory and exe-cutes it.
Incorrect answers:
msfpayload
https://www.offensive-security.com/metasploit-unleashed/msfpayload/
MSFpayload is a command line instance of Metasploit that is used to generate and output all of the various types of shellcode that are available in Metasploit. The most common use of this tool is for the generation of shellcode for an exploit that is not currently in the Metasploit Framework or for testing different types of shellcode and options before finalizing an Exploit Module.
msfcli
https://www.offensive-security.com/metasploit-unleashed/msfcli/
The msfcli provides a powerful command line interface to the framework. This allows you to easily add Metasploit exploits into any scripts you may create.

NEW QUESTION # 268
In the process of footprinting a target website, an ethical hacker utilized various tools to gather critical information. The hacker encountered a target site where standard web spiders were ineffective due to a specific file in its root directory. However, they managed to uncover all the files and web pages on the target site, monitoring the resulting incoming and outgoing traffic while browsing the website manually. What technique did the hacker likely employ to achieve this?

• A. Using Photon to retrieve archived URLs of the target website from archive.org
• B. Using the Netcraft tool to gather website information
• C. Examining HTML source code and cookies
• D. User-directed spidering with tools like Burp Suite and WebScarab

Answer: D

Explanation:
User-directed spidering is a technique that allows the hacker to manually browse the target website and use a proxy or spider tool to capture and analyze the traffic. This way, the hacker can discover hidden or dynamic content that standard web spiders may miss due to a specific file in the root directory, such as robots.txt, that instructs them not to crawl certain pages or directories. User-directed spidering can also help the hacker to bypass authentication or authorization mechanisms, as well as identify vulnerabilities or sensitive information in the target website. User-directed spidering can be performed with tools like Burp Suite and WebScarab, which are web application security testing tools that can intercept, modify, and replay HTTP requests and responses, as well as perform various attacks and scans on the target website.
The other options are not likely to achieve the same results as user-directed spidering. Using Photon to retrieve archived URLs of the target website from archive.org may provide some historical information about the website, but it may not reflect the current state or content of the website. Using the Netcraft tool to gather website information may provide some general information about the website, such as its IP address, domain name, server software, or hosting provider, but it may not reveal the specific files or web pages on the website.
Examining HTML source code and cookies may provide some clues about the website's structure, functionality, or user preferences, but it may not expose the hidden or dynamic content that user-directed spidering can discover. References:

NEW QUESTION # 270
An attacker redirects the victim to malicious websites by sending them a malicious link by email. The link appears authentic but redirects the victim to a malicious web page, which allows the attacker to steal the victim's data. What type of attack is this?

• A. Vlishing
• B. Spoofing
• C. DDoS
• D. Phishing

Answer: D

Explanation:
https://en.wikipedia.org/wiki/Phishing
Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. It occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message. The recipient is then tricked into clicking a malicious link, which can lead to the installation of malware, the freezing of the system as part of a ransomware attack, or the revealing of sensitive information.
An attack can have devastating results. For individuals, this includes unauthorized purchases, the stealing of funds, or identify theft.
Moreover, phishing is often used to gain a foothold in corporate or governmental networks as a part of a larger attack, such as an advanced persistent threat (APT) event. In this latter scenario, employees are compromised in order to bypass security perimeters, distribute malware inside a closed environment, or gain privileged access to secured data.
An organization succumbing to such an attack typically sustains severe financial losses in addition to declining market share, reputation, and consumer trust. Depending on the scope, a phishing attempt might escalate into a security incident from which a business will have a difficult time recovering.

NEW QUESTION # 271
John, a professional hacker, decided to use DNS to perform data exfiltration on a target network, in this process, he embedded malicious data into the DNS protocol packets that even DNSSEC cannot detect. Using this technique. John successfully injected malware to bypass a firewall and maintained communication with the victim machine and C&C server. What is the technique employed by John to bypass the firewall?

• A. DNS tunneling method
• B. DNSSEC zone walking
• C. DNS cache snooping
• D. DNS enumeration

Answer: A

Explanation:
DNS tunneling may be a method wont to send data over the DNS protocol, a protocol which has never been intended for data transfer. due to that, people tend to overlook it and it's become a well-liked but effective tool in many attacks. Most popular use case for DNS tunneling is obtaining free internet through bypassing captive portals at airports, hotels, or if you are feeling patient the not-so-cheap on the wing Wi-Fi. On those shared internet hotspots HTTP traffic is blocked until a username/password is provided, however DNS traffic is usually still allowed within the background: we will encode our HTTP traffic over DNS and voila, we've internet access. This sounds fun but reality is, browsing anything on DNS tunneling is slow. Like, back to 1998 slow. Another more dangerous use of DNS tunneling would be bypassing network security devices (Firewalls, DLP appliances...) to line up an immediate and unmonitored communications channel on an organisation's network. Possibilities here are endless: Data exfiltration, fixing another penetration testing tool... you name it. To make it even more worrying, there's an outsized amount of easy to use DNS tunneling tools out there. There's even a minimum of one VPN over DNS protocol provider (warning: the planning of the web site is hideous, making me doubt on the legitimacy of it). As a pentester all this is often great, as a network admin not such a lot .
How does it work:
For those that ignoramus about DNS protocol but still made it here, i feel you deserve a really brief explanation on what DNS does: DNS is sort of a phonebook for the web , it translates URLs (human-friendly language, the person's name), into an IP address (machine-friendly language, the phone number). That helps us remember many websites, same as we will remember many people's names. For those that know what DNS is i might suggest looking here for a fast refresh on DNS protocol, but briefly what you would like to understand is: * A Record: Maps a website name to an IP address. example.com ? 12.34.52.67 * NS Record (a.k.a. Nameserver record): Maps a website name to an inventory of DNS servers, just in case our website is hosted in multiple servers. example.com ? server1.example.com, server2.example.com Who is involved in DNS tunneling? * Client. Will launch DNS requests with data in them to a website . * One Domain that we will configure. So DNS servers will redirect its requests to an outlined server of our own. * Server. this is often the defined nameserver which can ultimately receive the DNS requests. The 6 Steps in DNS tunneling (simplified): 1. The client encodes data during a DNS request. The way it does this is often by prepending a bit of knowledge within the domain of the request. for instance : mypieceofdata.server1.example.com 2. The DNS request goes bent a DNS server. 3. The DNS server finds out the A register of your domain with the IP address of your server. 4. The request for mypieceofdata.server1.example.com is forwarded to the server. 5. The server processes regardless of the mypieceofdata was alleged to do. Let's assume it had been an HTTP request. 6. The server replies back over DNS and woop woop, we've got signal.
Bypassing Firewalls through the DNS Tunneling Method DNS operates using UDP, and it has a 255-byte limit on outbound queries. Moreover, it allows only alphanumeric characters and hyphens. Such small size constraints on external queries allow DNS to be used as an ideal choice to perform data exfiltration by various malicious entities. Since corrupt or malicious data can be secretly embedded into the DNS protocol packets, even DNSSEC cannot detect the abnormality in DNS tunneling. It is effectively used by malware to bypass the firewall to maintain communication between the victim machine and the C&C server. Tools such as NSTX (https://sourceforge.net), Heyoka (http://heyoka.sourceforge.netuse), and Iodine (https://code.kryo.se) use this technique of tunneling traffic across DNS port 53.

NEW QUESTION # 272
You are a cybersecurity specialist at CloudTech Inc., a company providing cloud-based services. You are managing a project for a client who wants to migrate their sensitive data to a public cloud service. To comply with regulatory requirements, the client insists on maintaining full control over the encryption keys even when the data is at rest on the cloud. Which of the following practices should you implement to meet this requirement?

• A. Use the cloud service provider's default encryption and key management services.
• B. Rely on Secure Sockets Layer (SSL) encryption for data at rest.
• C. Use the cloud service provider's encryption services but store keys on-premises.
• D. Encrypt data client-side before uploading to the cloud and retain control of the encryption keys.

Answer: D

Explanation:
The best practice to meet the client's requirement is to encrypt data client-side before uploading to the cloud and retain control of the encryption keys. This practice is also known as client-side encryption or end-to-end encryption, and it involves encrypting the data on the client's device using a software or hardware tool that generates and manages the encryption keys. The encrypted data is then uploaded to the cloud service, where it remains encrypted at rest. The encryption keys are never shared with the cloud service provider or any third party, and they are only used by the client to decrypt the data when needed. This way, the client can maintain full control over the encryption keys and the security of the data, even when the data is stored on a public cloud service12.
The other options are not as optimal as option D for the following reasons:
* A. Use the cloud service provider's encryption services but store keys on-premises: This option is not feasible because it contradicts the client's requirement of maintaining full control over the encryption keys. Using the cloud service provider's encryption services means that the client has to rely on the
* cloud service provider to generate and manage the encryption keys, even if the keys are stored on-premises. The cloud service provider may have access to the keys or the ability to decrypt the data, which may compromise the security and privacy of the data. Moreover, storing the keys on-premises may introduce additional challenges, such as key distribution, synchronization, backup, and recovery3.
* B. Use the cloud service provider's default encryption and key management services: This option is not desirable because it violates the client's requirement of maintaining full control over the encryption keys. Using the cloud service provider's default encryption and key management services means that the client has to trust the cloud service provider to encrypt and decrypt the data on the server-side, using the cloud service provider's own encryption keys and mechanisms. The cloud service provider may have access to the keys or the ability to decrypt the data, which may compromise the security and privacy of the data. Furthermore, the cloud service provider's default encryption and key management services may not meet the regulatory requirements or the security standards of the client4.
* C. Rely on Secure Sockets Layer (SSL) encryption for data at rest: This option is not sufficient because SSL encryption is not designed for data at rest, but for data in transit. SSL encryption is a protocol that encrypts the data as it travels over the internet between the client and the server, using certificates and keys that are exchanged and verified by both parties. SSL encryption can protect the data from being intercepted or modified by unauthorized parties, but it does not protect the data from being accessed or decrypted by the cloud service provider or any third party who has access to the server. Moreover, SSL encryption does not provide the client with any control over the encryption keys or the security of the data.
