“Boolean based” we mean that it is based on Boolean values, that is, true or false / true and false. AND Time-based SQL Injection is an inferential SQL Injection technique that relies on sending an SQL query to the database which forces the database to wait for a specified amount of time (in seconds) before responding. The response time will indicate to the attacker whether the result of the query is TRUE or FALSE.

Boolean-based (content-based) Blind SQLi

Boolean-based SQL Injection is an inferential SQL Injection technique that relies on sending an SQL query to the database which forces the application to return a different result depending on whether the query returns a TRUE or FALSE result.

Depending on the result, the content within the HTTP response will change, or remain the same. This allows an attacker to infer if the payload used returned true or false, even though no data from the database is returned. This attack is typically slow (especially on large databases) since an attacker would need to enumerate a database, character by character.

Time-based Blind SQLi

Time-based SQL Injection is an inferential SQL Injection technique that relies on sending an SQL query to the database which forces the database to wait for a specified amount of time (in seconds) before responding. The response time will indicate to the attacker whether the result of the query is TRUE or FALSE.

Depending on the result, an HTTP response will be returned with a delay, or returned immediately. This allows an attacker to infer if the payload used returned true or false, even though no data from the database is returned. This attack is typically slow (especially on large databases) since an attacker would need to enumerate a database character by character.

Operational Technology and ICS environments often suffer from misconfigurations such as unchanged factory-default passwords. CEH identifies exploiting default credentials as a direct and effective method because ICS devices frequently lack strong authentication controls. Using these built-in credentials grants immediate unauthorized access to supervisory controls, enabling adversaries to manipulate configurations, disrupt processes, or escalate attacks across critical systems.

This scenario aligns with a Replay Attack against RF-based smart key systems, covered in CEH v13 IoT and OT Hacking. Attackers capture radio-frequency signals transmitted by key fobs and replay them to unlock vehicles.

CEH v13 emphasizes that detecting and preventing such attacks requires monitoring wireless RF signals for anomalies such as signal replay, interference, or jamming patterns. RF analysis helps confirm unauthorized signal capture and retransmission.

Firmware updates may mitigate future vulnerabilities, but confirmation requires RF monitoring. Physical surveillance and smartphone malware controls are unrelated to RF replay attacks. Therefore, option D is correct.

The Certified Ethical Hacker (CEH) Footprinting and Reconnaissance module defines Google Hacking, also known as Google Dorking, as the use of advanced search operators to uncover sensitive information unintentionally exposed on the public internet. This technique remains passive, making it ideal during early reconnaissance.

Google Hacking can reveal:

Exposed configuration files

Backup files (.bak, .old, .zip)

Error messages and stack traces

Source code fragments and scripting errors

These findings often indicate coding weaknesses or insecure configurations within a web application. CEH explicitly highlights Google Dorking as an effective way to identify web application weaknesses without scanning or exploiting the target directly.

Option C is correct because Google Hacking is commonly used to identify coding and configuration weaknesses exposed through indexed files.

Option A may be possible indirectly but is not the primary justification.

Option B is incorrect because Google does not index the Deep Web.

Option D involves internal network discovery, which Google Hacking cannot directly achieve.

CEH emphasizes Google Hacking as a powerful passive reconnaissance technique for discovering exposed vulnerabilities.
