Btlejack is a tool used for attacking Bluetooth Low Energy (BLE) connections, including sniffing, jamming, and hijacking.
* The -f option specifies the access address of the BLE connection.
* The -j option is used to hijack an active BLE connection.
Therefore, the correct syntax to hijack a BLE connection is:
btlejack -f [access_address] -j
This matches Option A: btlejack -f 0x129f3244 -j
Incorrect Options:
* B. -c any is used for sniffing any advertising packet but not for hijacking.
* C. -d specifies device paths; -s starts a scan but does not hijack.
* D. This is likely a malformed or unrelated command in the context of hijacking.

In active session hijacking, after identifying a valid session, the attacker must desynchronize the legitimate communication between the client and the server. To do this, Bob should:
* Knock one of the parties offline (typically the client).
* Then spoof the session by injecting crafted packets using the guessed sequence number.
From CEH v13 Courseware:
* Module 11: Session Hijacking
CEH v13 Study Guide states:
"After identifying a session and predicting its sequence number, the attacker forces the original user offline, allowing them to assume control over the connection using spoofed packets." Incorrect Options:
* A: Taking over the session is the ultimate goal, but the necessary step before that is disconnecting the original participant.
* B: Sequence prediction is already done.
* C: Sequence number has already been guessed.

Types of Password Attacks - Active Online Attacks: Internal Monologue Attack Attackers perform an internal monologue(##) attack using SSPI (Security Support Provider Interface) from a user-mode application, where a local procedure call to the NTLM authentication package is invoked to calculate the NetNTLM response in the context of the logged-on user.Attacker disables the security controls of NetNTLMv1, extracts all the non- network logon tokens from all the active processes to masquerade as legitimate users. (P.594/578)

Brute-force attack when an attacker uses a set of predefined values to attack a target and analyze the response until he succeeds. Success depends on the set of predefined values. It will take more time if it is larger, but there is a better probability of success. In a traditional brute-force attack, the passcode or password is incrementally increased by one letter/number each time until the right passcode/password is found.
