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 letter 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 enables using a specially crafted packet sent to the hardware address of the access point.
B. It is still possible for a hacker to connect to the network after sniffing the SSID from a successful wireless association.
C. Disabling SSID broadcast prevents 802.11 beacons from being transmitted from the access point,
resulting in a valid setup leveraging “security through obscurity”.
D. Since the SSID is required in order to connect, the 32-character string is sufficient to prevent brute-force attacks.

In cryptanalysis and computer security, 'pass the hash' is a hacking technique that allows an attacker to authenticate to a remote server/service by using the underlying NTLM and/or LanMan hash of a user's password, instead of requiring the associated plaintext password as is normally the case. Metasploit Framework has a module for the technique; psexec. The psexec module is often used by penetration testers to obtain access to a given system that you already know the credentials for. It was written by sysinternals and has been integrated within the framework. Often as
penetration testers, successfully gain access to a system through some exploit, use meterpreter to grab the passwords or other methods like fgdump,pwdump, or cachedump and then utilize rainbow tables to crack
those hash values.

Which of the following is true hash type and sort order that is used in the psexec module’s ‘smbpass’

A. NTLM:LM
B. LM:NT
C. LM:NTLM
D. NT:LM
