NEW QUESTION # 40
What is the main purpose of a "SQL injection" attack?
Answer: A
Explanation:
SQL Injection (SQLi) is one of the most prevalent and damaging information security threats targeting web applications. Its main purpose is to exploit a database by manipulating Structured Query Language (SQL) commands through user-supplied input. This occurs when an application fails to properly filter or "sanitize" data entered into forms, URL parameters, or cookies, allowing an attacker to "inject" their own SQL code into the query that the application sends to the back-end database.
When successful, a SQL injection attack can have catastrophic consequences for an organization's data integrity and confidentiality. An attacker can bypass authentication to log in as an administrator without a password, view sensitive user data, modify or delete database records, and in some cases, gain administrative control over the entire database server. A classic example is the ' OR 1=1 -- injection, which forces a query to return "true" regardless of the credentials provided, effectively opening the door to the system.
Managing the threat of SQLi is a top priority for web security. The most effective defense is the use of
"Parameterized Queries" (also known as prepared statements), which ensure that the database treats user input as data rather than executable code. Additionally, implementing "Input Validation" and the "Principle of Least Privilege" for database accounts helps mitigate the potential damage. From an ethical hacking standpoint, identifying SQLi vulnerabilities is a core component of vulnerability scanning and manual testing. Because databases often hold an organization's most valuable assets-including customer identities and financial records-protecting them from injection attacks is a non-negotiable aspect of modern information security management.
NEW QUESTION # 41
What is a backdoor in terms of computer security?
Answer: B
Explanation:
In computer security, a backdoor refers to ahidden method of accessing a system that bypasses normal authentication and security mechanisms, making option A the correct answer. Backdoors can be intentionally created by developers for maintenance purposes or maliciously installed by attackers after compromising a system.
From an ethical hacking perspective, backdoors are commonly discovered duringpost-exploitation activities.
Attackers use them to maintain persistent access, even if passwords are changed or vulnerabilities are patched.
Backdoors may take the form of hidden user accounts, modified services, malicious scripts, or hardcoded credentials.
Option B is incorrect because malware that spreads through instant messaging is typically classified as a worm or trojan, not specifically a backdoor. Option C is incorrect because a backdoor is not a legitimate or documented access point.
Understanding backdoors is essential for managing information security threats. Ethical hackers identify backdoors to demonstrate long-term risks and highlight weaknesses in system monitoring and access controls.
Defenders can mitigate backdoor threats by implementing integrity monitoring, endpoint detection and response (EDR), regular audits, and strict access management.
Backdoors pose significant risks because they undermine trust in system security. Identifying and removing them is critical for restoring system integrity and preventing repeated compromise.
NEW QUESTION # 42
What is active reconnaissance?
Answer: B
Explanation:
Active reconnaissance is a phase of ethical hacking in which information is gathered bydirectly interacting with the target system. This makes option C the correct answer. Unlike passive reconnaissance, active reconnaissance involves sending requests, probes, or packets to the target to elicit responses that reveal useful technical details.
Common active reconnaissance techniques includeport scanning,service enumeration,banner grabbing,DNS queries, andnetwork mapping. These methods help ethical hackers identify open ports, running services, operating systems, and potential vulnerabilities. Active reconnaissance is typically conducted after passive techniques have provided initial intelligence.
Option A is incorrect because recognizing a target without action does not describe reconnaissance behavior.
Option B is also incorrect because observing without interaction definespassive reconnaissance, not active reconnaissance.
From an ethical hacking perspective, active reconnaissance is more intrusive and therefore more likely to be detected by intrusion detection systems or firewalls. Because of this, it must always be performed withexplicit authorization. Despite the increased risk of detection, active reconnaissance provides far more accurate and actionable information, making it essential for effective penetration testing.
Understanding the distinction between active and passive reconnaissance helps security professionals choose the correct techniques based on scope, authorization, and risk tolerance. Properly managed, active reconnaissance enables organizations to identify weaknesses early and strengthen their defensive security posture.
NEW QUESTION # 43
Which command is used to update Kali Linux from the console?
Answer: B
Explanation:
Updating an operating system is a fundamental aspect of maintaininginformation security hygiene, especially in security-focused distributions such as Kali Linux. The correct command used to update the package list in Kali Linux from the console is sudo apt-get update, making option C the correct answer.
This command synchronizes the local package index with the repositories configured on the system. It does not install upgrades itself but retrieves the latest information about available software versions and security patches. Ethical hackers and security professionals rely on updated systems to ensure that tools function correctly and that known vulnerabilities are patched.
Option A is incorrect because it is not a valid Linux command. Option B is incorrect due to invalid characters and improper syntax. Proper command accuracy is critical in security environments, as incorrect commands can lead to system instability or incomplete updates.
From an ethical hacking standpoint, keeping Kali Linux updated ensures access to the latest penetration testing tools, vulnerability scanners, and security fixes. Many exploits target outdated software, so regular updates significantly reduce exposure to known threats.
Understanding system maintenance commands supports secure operations and reinforces best practices in defensive security and professional ethical hacking workflows.
NEW QUESTION # 44
What is a reverse shell?
Answer: A
Explanation:
A reverse shell is a technique used in ethical hacking and penetration testing where the target (victim) system initiates a connection back to the attacker's system, allowing the attacker to execute commands remotely. This makes option C the correct answer.
Unlike a bind shell, where the victim opens a listening port, a reverse shell is particularly effective in environments protected by firewalls or Network Address Translation (NAT). Since outbound connections are often allowed, the victim system connects outward to the attacker, bypassing many network restrictions.
Ethical hackers commonly use reverse shells during the exploitation and post-exploitation phases of penetration testing to maintain access to compromised systems.
Option A is incorrect because running a terminal as root does not define a reverse shell. Option B is incorrect because a reverse shell is not a standard command-line interface but rather a remote command execution channel.
From an ethical hacking perspective, reverse shells help demonstrate the real-world impact of vulnerabilities such as command injection, remote code execution, or misconfigured services. Once established, a reverse shell may allow privilege escalation, lateral movement, or data exfiltration-highlighting serious security risks.
Understanding reverse shells is essential for both attackers and defenders. Defenders can mitigate reverse shell attacks by implementing strict egress filtering, intrusion detection systems, endpoint protection, and proper system hardening. Ethical testing of reverse shells enables organizations to identify weaknesses and improve overall security posture.
