While examining a log report you find out that an intrusion has been attempted by a machine
whose IP address is displayed as 3405906949. It looks to you like a decimal number. You
perform a ping 3405906949. Which of the following IP addresses will respond to the ping and
hence will likely be responsible for the the intrusion ?
A. 192.34.5.9
B. 10.0.3.4
C. 203.2.4.5
D. 199.23.43.4

>>ada cara nk tukar IP address 3405906949 kpd 203.2.4.5...menarik gak r...

John is the network administrator of XSECURITY systems. His network was
recently compromised. He analyzes the logfiles to investigate the attack.
Take a look at the following Linux logfile snippet. The hacker compromised and
"owned" a Linux machine. What is the hacker trying to accomplish here?

[root@apollo /]# rm rootkit.c
[root@apollo /]# [root@apollo /]# ps -aux | grep inetd ; ps -aux | grep portmap ;
rm/sbin/portmap ; rm /tmp/h ; rm /usr/sbin/rpc.portmap ; rm -rf .bash* ; rm -
rf/root/.bash_history ; rm - rf /usr/sbin/namedps -aux | grep inetd ; ps -aux | grep
portmap ; rm /sbin/por359 ? 00:00:00 inetd 359 ? 00:00:00 inetd
rm: cannot remove `/tmp/h': No such file or directory
rm: cannot remove `/usr/sbin/rpc.portmap': No such file or directory
[root@apollo /]# ps -aux | grep portmap
[root@apollo /]# [root@apollo /]# ps -aux | grep inetd ; ps -aux | grep portmap ; rm
/sbin/portmap ;
rm /tmp/h ; rm /usr/sbin/rpc.portmap ; rm -rf .bash* ; rm -rf /root/.bash_history ;

Travis works primarily from home as a medical transcriptions.
He just bought a brand new Dual Core Pentium Computer with over 3 GB of RAM.
He uses voice recognition software is processor intensive, which is why he bought
the new computer. Travis frequently has to get on the Internet to do research on
what he is working on. After about two months of working on his new computer, he
notices that it is not running nearly as fast as it used to.
Travis uses antivirus software, anti-spyware software and always keeps the
computer up-to-date with Microsoft patches.
After another month of working on the computer, Travis computer is even more
noticeable slow. Every once in awhile, Travis also notices a window or two pop-up
on his screen, but they quickly disappear. He has seen these windows show up, even
when he has not been on the Internet. Travis is really worried about his computer
because he spent a lot of money on it and he depends on it to work. Travis scans his
through Windows Explorer and check out the file system, folder by folder to see if
there is anything he can find. He spends over four hours pouring over the files and
folders and can't find anything but before he gives up, he notices that his computer
only has about 10 GB of free space available. Since has drive is a 200 GB hard drive,
Travis thinks this is very odd.
Travis downloads Space Monger and adds up the sizes for all the folders and files on
his computer. According to his calculations, he should have around 150 GB of free
space. What is mostly likely the cause of Travi's problems?

A. Travis's Computer is infected with stealth kernel level rootkit
B. Travi's Computer is infected with Stealth Torjan Virus
C. Travis's Computer is infected with Self-Replication Worm that fills the hard disk
space
D. Logic Bomb's triggered at random times creating hidden data consuming junk files

>>ni soalan yg paling menarik perhatian aku...ni penerangan bg jwpn dia :-

Explanation: A rootkit can take full control of a system. A rootkit's only purpose is
to hide files, network connections, memory addresses, or registry entries from other
programs used by system administrators to detect intended or unintended special
privilege accesses to the computer resources
