Description:
\r\n\r\nTryHackMe made familiarizing with Nessus nice and easy with this free room with 5 tasks.
\r\n\r\nMy impression is that the room authors’ sentences are clear and explanations are easy to follow, you won’t get much trouble with this room unless you don’t allocate enough of system resources to install Nessus. Yes, you have to install Nessus on your own machine and use OpenVPN configuration file provided with your THM account, not AttackBox nor subcription will help you with that.
\r\n\r\nSo, the installation will take some time… You will probably want to move on something else in the meantime or sleep on it.
\r\n\r\nRead the instructions provided in the room, i will post here only tasks that need answers, screenshots that lead to answers and spoilers. These are tasks 3-5.
\r\n\r\nNot to ruin the party for interested, answers are hidden, so if interested, click on the question below and the answer will reveal itself. Let’s go!\r\n\r\n
TASK 3: Navigation and Scans
\r\n\r\nWhat is the name of the button which is used to launch a scan?
New Scan\r\nWhat side menu option allows us to create custom templates?
\r\nPolicies\r\nWhat menu allows us to change plugin properties such as hiding them or changing their severity?
\r\nPlugin Rules\r\nIn the ‘Scan Templates’ section after clicking on ‘New Scan’, what scan allows us to see simply what hosts are alive?
\r\nHost Discovery\r\nOne of the most useful scan types, which is considered to be ‘suitable for any host’?
\r\nBasic Network Scan\r\nWhat scan allows you to ‘Authenticate to hosts and enumerate missing updates’?
\r\nCredentialed Patch Audit\r\n\r\nWhat scan is specifically used for scanning Web Applications?
\r\nWeb Application Tests\r\nTask 4: Scanning!
\r\n\r\n\r\nCreate a new ‘Basic Network Scan’ targeting the deployed VM. What option can we set under ‘BASIC’ (on the left) to set a time for this scan to run? This can be very useful when network congestion is an issue.
\r\nSchedule\r\n\r\nUnder ‘DISCOVERY’ (on the left) set the ‘Scan Type’ to cover ports 1-65535. What is this type called?
\r\nPort scan (all ports)\r\n\r\nWhat ‘Scan Type’ can we change to under ‘ADVANCED’ for lower bandwidth connection?
\r\nScan low bandwidth links\r\n\r\nAfter the scan completes, which ‘Vulnerability’ in the ‘Port scanners’ family can we view the details of to see the open ports on this host?
\r\nNessus SYN scanner\r\n\r\nWhat Apache HTTP Server Version is reported by Nessus?
\r\n2.4.99\r\nTask 5: Scanning a Web Application!
\r\n\r\n\r\nWhat is the plugin id of the plugin that determines the HTTP server type and version?
\r\n10107\r\n\r\nWhat authentication page is discovered by the scanner that transmits credentials in cleartext?
\r\nlogin.php\r\n\r\nWhat is the file extension of the config backup?
\r\n.bak\r\n\r\nWhich directory contains example documents? (This will be in a php directory)
