Information Gathering Tools: Attackers use information gathering tools such as Shodan and Censys to gather basic information about the target device and network.

Anyone can send an encrypted message to Bob but only Bob can read it. Using PKI, when Alice wishes to send an encrypted message to Bob, she looks up Bob's public key in a directory, uses it to encrypt the message, and sends it off. Bob then uses his private key to decrypt the message and read it. No one listening in can decrypt the message. Thus, although many people may know the public key of Bob and use it to verify Bob's signatures, they cannot discover Bob's private key and use it to forge digital signatures. This is referred to as the principle of: Irreversibility Non-repudiation Symmetry Asymmetry

John's company is facing a DDoS attack. While analyzing the attack, John has learned that the attack is originating from the entire globe, and filtering the traffic at the Internet Service Provider's (ISP) level is an impossible task to do. After a while, John has observed that his personal computer at home was also compromised similar to that of the company's computers. He observed that his computer is sending large amounts of UDP data directed toward his company's public IPs. John takes his personal computer to work and starts a forensic investigation. Two hours later, he earns crucial information: the infected computer is connecting to the C&C server, and unfortunately, the communication between C&C and the infected computer is encrypted. Therefore, John intentionally lets the infection spread to another machine in his company's secure network, where he can observe and record all the traffic between the Bot software and the Botnet. After thorough analysis he discovered an interesting thing that the initial process of infection downloaded the malware from an FTP server which consists of username and password in cleartext format. John connects to the FTP Server and finds the Botnet software including the C&C on it, with username and password for C&C in configuration file. What can John do with this information?

During the penetration testing in company "Credit Cards Rus Ltd." Marin was using sslstrip tool in order to sniff HTTP traffic. Unfortunately, no data was received. Marin double checked the setup, tested the setup between his virtual machines, and was successful in intercepting the traffic here, but when he tried to do it against other machines on the same network, nothing happened. Marin was puzzled with that and he did not understand why that was happening. Help Marin and explain why he was unsuccessful with intercepting the traffic with sslstrip? Sslstrip can show the data only if the initial request to the server is sent as HTTP. Marin cannot use sslstrip on the real network—it works only between virtual machines Marin was using the wrong tool. To decrypt the https traffic, he should have used httpsdecrypt instead Sslstrip can show only GET requests—in this case, all the client/server communication was using POST requests

Sslstrip can show the data only if the initial request to the server is sent as HTTP.

During the penetration testing in company "Credit Cards Rus Ltd." Marin was using the sslstrip tool in order to sniff HTTPS traffic. Knowing that HTTPS traffic is encrypted and cannot be sniffed normally, explain the reason why it is possible to see the traffic in cleartext. Sslstrip tool is exploiting user behavior and if a user does not type https:// in front of the link, and the website has redirection from HTTP to HTTPS, it will intercept HTTP 302 redirection and send the user exactly what the user asked for, i.e. HTTPsite Sslstrip tool is exploiting an older or in HTTPS protocol, allowing it to gracefully decrypt http traffic by intercepting HTTP 403 denied messages and sending user HTTP 200 OK messages Sslstrip tool is exploiting certificate signing and it is sending its own certificate instead of the original one, allowing for the traffic to be easily decrypted Sslstrip tool is exploiting network bug, which allows it to decrypt HTTPS protocols (TLS and SSL) by sending gratuitous ARP packets to all the nodes on the network

Which protocol and port number might be needed to send log messages to a log analysis tool that resides behind a firewall? UDP 123 UDP 541 UDP 514 UDP 415

UDP 514

While performing a UDP scan of a subnet, you receive an ICMP reply of Code 3/Type 3 for all the pings you have sent out. What is the most likely cause of this? The host does not respond to ICMP packets. UDP port is closed. UDP port is open The firewall is dropping the packets.

UDP port is closed.

UDP port scanners use the UDP protocol instead of the TCP. There is no three-way handshake for UDP scan. The UDP protocol can be more challenging to use than the TCP scanning because you can send a packet, but you cannot determine whether the host is alive, dead, or filtered. However, you can use one ICMP that checks for open or closed ports.

Susan works for "CustomData Intl." and she has to deploy a guest Wi-Fi. She did everything by the manual and deployed the guest Wi-Fi successfully. The deployed guest Wi-Fi is separated from the company network, it is protected with WPA2 and every user wants to use the Wi-Fi has to ask for a username and password. There is one problem though—after a few months she noticed that the users connecting to the guest Wi-Fi are being attacked with MitM attacks. She identified that the MitM attack was initiated with ARP spoofing. She found that someone is stealing users' web application credentials, including Windows system credentials in some cases. Unfortunately, internal users have also become prey to these attacks since they used guest Wi-Fi because it was more open than their internal network. So, only external guests are not being compromised. She wanted to mitigate this issue and the first step she took was to ban all internal users from guest using Wi-Fi network. What, according to you, is the easiest and probably the best way to prevent the ARP spoofing attacks on Wi-Fi networks? Use Client isolation WiFi feature Use IPsec on WiFi Use HTTPS all the time It's impossible to protect WiFi from ARP spoofing
