Question # 90

A particular database threat utilizes a SQL injection technique to penetrate a target system. How would an attacker use this technique to compromise a database?

An attacker gains control of system to flood the target system with requests, preventing legitimate users from gaining access

An attacker utilizes an incorrect configuration that leads to access with higher-than-expected privilege of the database

Question # 93

Bill has successfully executed a buffer overflow against a Windows IIS web server. He has been able to spawn an interactive shell and plans to deface the main web page. He first attempts to use the "echo" command to simply overwrite index.html and remains unsuccessful. He then attempts to delete the page and achieves no progress. Finally, he tries to overwrite it with another page in which also he remains unsuccessful. What is the probable cause of Bill's problem?

You cannot use a buffer overflow to deface a web page

There is a problem with the shell and he needs to run the attack again

Question # 94

What are the main drawbacks for anti-virus software?

AV software is difficult to keep up to the current revisions.

AV software can detect viruses but can take no action.

AV software is signature driven so new exploits are not detected.

Itâ€™s relatively easy for an attacker to change the anatomy of an attack to bypass AV systems

AV software isnâ€™t available on all major operating systems platforms.

AV software is very machine (hardware) dependent.

Question # 95

Joe the Hacker breaks into XYZâ€™s Linux system and plants a wiretap program in order to sniff passwords and user accounts off the wire. The wiretap program is embedded as a Trojan horse in one of the network utilities. Joe is worried that network administrator might detect the wiretap program by querying the interfaces to see if they are running in promiscuous mode.

What can Joe do to hide the wiretap program from being detected by ifconfig command?

Block output to the console whenever the user runs ifconfig command by running screen capture utiliyu

Run the wiretap program in stealth mode from being detected by the ifconfig command.

Replace original ifconfig utility with the rootkit version of ifconfig hiding Promiscuous information being displayed on the console.

Henry is executing commands or viewing data outside the intended target path

Henry is using a denial of service attack which is a valid threat used by an attacker

Henry is taking advantage of an incorrect configuration that leads to access with higher-than-expected privilege

Henry uses poorly designed input validation routines to create or alter commands to gain access to unintended data or execute commands
