QUESTION: 26

An attacker finds a web page for a target organization that supplies contact information for the company. Using available details to make the message seem authentic, the attacker drafts e-mail to an employee on the contact page that appears to come from an individual who might reasonably request confidential information, such as a network administrator. The email asks the employee to log into a bogus page that requests the employee's user name and password or click on a link that will download spyware or other malicious programming. Google's Gmail was hacked using this technique and attackers stole source code and sensitive data from Google servers. This is highly sophisticated attack using zero-day exploit vectors, social engineering and malware websites that focused on targeted individuals working for the company.
What is this deadly attack called?

Spear phishing attack
Trojan server attack
Javelin attack
Social networking attack

QUESTION: 28

How does traceroute map the route a packet travels from point A to point B?

Uses a TCP timestamp packet that will elicit a time exceeded in transit message
Manipulates the value of the time to live (TTL) within packet to elicit a time exceeded in transit message
Uses a protocol that will be rejected by gateways on its way to the destination
Manipulates the flags within packets to force gateways into generating error messages

Answer(s): B

Explanation:

Traceroute works by increasing the "time-to-live" value of each successive batch of packets sent. The first three packets have a time-to-live (TTL) value of one (implying that they make a single hop). The next three packets have a TTL value of 2, and so on.
When a packet passes through a host, normally the host decrements the TTL value by one, and forwards the packet to the next host.
When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded (type 11) packet to the sender. The traceroute utility uses these returning packets to produce a list of hosts that the packets have traversed en route to the destination.
