Phishing attacks use 'spoofed' e-mails and fraudulent websites
designed to Fool recipients into divulging personal financial data
such as credit card numbers, account usernames and passwords,
social security numbers, etc.
By hijacking the trusted brands of well-known banks, online
retailers and credit card companies, phishers are able to convince
up to 5% of recipients to respond to them.
People bid on objects. When it becomes apparent they were out bid
they are approached via email to purchase the object that they bid
on but cheaper than it was auctioned off for. They make arrangements
to pay for the object they give up their credit card numbers and other
personal information. The people pay for the objects, but they never
receive them. The communications appears to have the Ebay logo and
formats normally seen on the Ebay site.

(Distributed Denial of Service Attack DDOS)
A "denial-of-service" attack is characterized by an explicit attempt
by attackers to prevent legitimate users of a service from using
that service. Examples include attempts to "flood" a network,
thereby preventing legitimate network traffic attempts to disrupt
connections between two machines, thereby preventing
access to a service attempts to prevent a particular individual
from accessing a service attempts to disrupt service to a specific
system or person
Denial-of-service (DOS) or Distributed Denial-of-service attacks
(DDOS) can essentially disable your computer or your network.
Depending on the nature of your enterprise, this can effectively
disable your organization.
Some denial-of-service attacks can be executed with limited
resources against a large, sophisticated site. This type of attack
is sometimes called an "asymmetric attack." For example, an
attacker with an old PC and a slow modem may be able to
disable much faster and more sophisticated machines or
Bots – Zombie PC’s
Trojans –DDOS- Smurf attack
This is a DDOS Attack tool, used by a attacker to send
a specified number of data packets to a victim.
A hacker can control both of these attacks remotely.
Virus – Code Red
Exploited MS OS’s used mathematic algorithm to generate IP addresses to attack. NOTE: First variant of Code Red’s Algorithm code was flawed and only specific IP address ranges were exploited. Once the author found out the algorithm was flawed, he/she corrected the code and the code traversed the world in a matter of hours.
What is war driving ?
Imagine a car equipped with nothing more than a laptop
computer, a portable GPS receiver, and a wireless network card
slowly strolls through your neighborhood !
The computer is looking for what is called an SSID.
An SSID is your wireless network name and it is
being constantly transmitted by your access point
letting computers know of its presence.
Transmitting SSID’s will improve network access
times, but be aware of the trade off !
WI-FI programs can track several access points
at the same time and are able to:
·Identify the SSID (if being broadcast)
·Monitor the signal strength
·Check to see if the network is encrypted.
·Obtain the IP address
·Obtain the MAC address
·The war-driver will generally configure his or her
software to log any strong unencrypted signals
even using a GPS receiver to record and log the
coordinates of the strong signal.
Specific types / wireless hardware vendors are assigned
specific MAC address ranges. Wireless scanning software
can identify the MAC and thus a experienced war-drive can
then associate the MAC with a specific hardware device.
The next thing they will do is to try to exploit the access
point using known hardware and software exploits.
Given enough time, using Brut Force attacks, a hacker may be able to access your wireless network.
Correct Configurations setups
are a must or you ‘will’ loose
your identity !
