When standard protections such as HTTPS, HTTP-only flags, and session regeneration are properly implemented, CEH teaches that predictable session identifiers become one of the few remaining avenues for session hijacking. Session token prediction involves analyzing entropy, randomness, or generation patterns within session IDs to mathematically infer future or valid tokens. If the application uses weak randomization algorithms, insufficient entropy sources, or predictable sequences, attackers may generate a valid session ID without direct interception. Techniques such as MitM interception or CSRF manipulation do not bypass strong transport-layer protections and cookie restrictions. Session fixation fails because the application regenerates the session ID upon login, invalidating pre-set identifiers. Therefore, the advanced and CEH-aligned method to hijack a protected session is predicting session IDs through side-channel or pattern analysis.

The hacker could have used the technique of manipulating white spaces in SQL queries to bypass signature detection. This technique involves inserting, removing, or replacing white spaces in SQL queries with other characters or symbols that are either ignored or interpreted as white spaces by the SQL engine, but not by the signature-based IDS. This way, the hacker can alter the appearance of the query and evade the pattern matching of the IDS, while preserving the functionality and logic of the query. For example, the hacker could replace the space character with a tab character, a newline character, a comment symbol, or a URL-encoded value, such as %2012.

The other options are not correct for the following reasons:

A. Utilizing the char encoding function to convert hexadecimal and decimal values into characters that pass-through SQL engine parsing: This option is not feasible because the char encoding function is not supported by all SQL engines, and it may not be able to convert all hexadecimal and decimal values into valid characters. Moreover, the char encoding function may not be able to bypass the signature detection of the IDS, as it may still match the keywords or syntax of the SQL query3.

B. Using the URL encoding method to replace characters with their ASCII codes in hexadecimal form: This option is not effective because the URL encoding method is not applicable to SQL queries, as it is designed for encoding special characters in URLs. The URL encoding method may not be able to replace all characters with their ASCII codes, and it may not be able to preserve the functionality and logic of the SQL query. Furthermore, the URL encoding method may not be able to evade the signature detection of the IDS, as it may still match the keywords or syntax of the SQL query4.

C. Implementing sophisticated matches such as “OR ‘john’ = john" in place of classical matches like “OR 1-1”: This option is not advanced because it is a common and basic SQL injection technique that does not involve any evasion or obfuscation. This technique involves injecting a logical expression that is always true, such as “OR ‘john’ = john” or “OR 1-1”, to bypass the authentication or authorization checks of the SQL query. However, this technique may not be able to bypass the signature detection of the IDS, as it may easily match the keywords or syntax of the SQL query.

CEH v13 teaches that NetBIOS enumeration is a key technique for gathering information in Windows environments without raising alarms. Ports 137 and 139 indicate that NetBIOS Name Service (NBNS) and SMB services are active. The tool nbtstat -A <IP> retrieves valuable information including computer names, logged-in users, domain/workgroup membership, and system roles—all passively and without authentication. CEH emphasizes that querying NetBIOS is often overlooked by defenders and generates minimal noise, making it ideal for stealth enumeration. LDAP enumeration (Option A) requires directory access and tends to trigger logs. Psloggedon and pspasswd (Options B and D) involve active interaction and authentication attempts, which are far more detectable. nbtstat is the CEH-recommended tool for initial reconnaissance on Windows networks using NetBIOS and SMB, especially when quiet enumeration is required.
