You are working as a Security Analyst in a company XYZ that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8.While monitoring the data, you find a high number of outbound connections. You see that IP's owned by XYZ (Internal) and private IP's are communicating to aSingle Public IP. Therefore, the Internal IP's are sending data to the Public IP.After further analysis, you find out that this Public IP is a blacklisted IP, and the internal communicating devices are compromised.What kind of attack does the above scenario depict?
Scenario:1. Victim opens the attacker's web site.2. Attacker sets up a web site which contains interesting and attractive content like 'Do you want to make $1000 in a day?'.3. Victim clicks to the interesting and attractive content URL.4. Attacker creates a transparent 'iframe' in front of the URL which the victim attempts to click, so the victim thinks that he/she clicks on the 'Do you want to make$1000 in a day?' URL but actually he/she clicks on the content or URL that exists in the transparent 'iframe' which is setup by the attacker.What is the name of the attack which is mentioned in the scenario?
A network administrator discovers several unknown files in the root directory of his Linux FTP server.

The ps command shows that the nc file is running as process, and the netstat command shows the nc process is listening on a network port.What kind of vulnerability must be present to make this remote attack possible?
