186. The network in ABC company is using the network address with mask In the network the servers are in the addresses, and
An attacker is trying to find those servers but he cannot see them in his scanning. The command he is using is:
Why he cannot see the servers?
He needs to add the command “”ip address”” just before the IP address
He is scanning from to because of the mask /28 and the servers are not in that range
The network must be down and the nmap command and IP address are ok
He needs to change the address to with the same mask

C. Netcat will listen for a connection from on port 1234 and output anything received to port 2222.
D. Netcat will listen on port 2222 and then output anything received to local interface

197. The company ABC recently contract a new accountant. The accountant will be working with the financial statements. Those financial statements need to be approved by the CFO and then they will be sent to the accountant but the CFO is worried because he wants to be sure that the information sent to the accountant was not modified once he approved it. What of the following options can be useful to ensure the integrity of the data?
The CFO can use a hash algorithm in the document once he approved the financial statements
The document can be sent to the accountant using an exclusive USB for that document
The financial statements can be sent twice, one by email and the other delivered in USB and the accountant can compare both to be sure is the same document
The CFO can use an excel file with a password

198. Which of the following is a hashing algorithm?

D. ROT13

199. LM hash is a compromised password hashing function. Which of the following parameters describe LM Hash:?

A. I
B. I, II, and III
D. I and II

200. What statement is true regarding LM hashes?
A. LM hashes consist in 48 hexadecimal characters.
B. LM hashes are based on AES128 cryptographic standard.
C. Uppercase characters in the password are converted to lowercase.
D. LM hashes are not generated when the password length exceeds 15 characters.

201. 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 this 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 using in the psexec module’s smbpass’?
