Useful Information for Security

Each day for us can be a good day for those, who are waiting to damage you some how. We have update our
knowledge regarding our activities in NET like they do. Times ago their version was that "they want to attack big
companies and show to others that they are able to do it. May be still there are some of those people that doing
not harmful attack only for their satisfaction. But to day's situation in NET shows us that those which are MAL....
are more and more any second. We have to learn how to keep clean our NET. We want to work and do many
good things that NET gives us the possibilities to do it. But with those around we are always under attacks. These
are some simple definition from those people that they know the problems better than I do. I just wanted to share
them with you, may be helps.

"The success of recent attacks illustrates that the standard approach of deploying
antivirus software to each computer in your organization may not be sufficient.
Recent outbreaks have spread with alarming speed, faster than the software
industry’s ability to detect, identify, and deliver antivirus tools that are capable of
protecting against attack. The techniques demonstrated by the latest forms of
malware have also become substantially more advanced, enabling the most recent
outbreaks to evade detection and propagate. These techniques include:
● Social engineering. Many attacks attempt to appear as if they originated from a
system administrator or official service, increasing the likelihood that end users
will execute them and infect their systems.
● Backdoor creation. The majority of recent outbreaks have attempted to open
some form of unauthorized access to already infected systems, enabling a hacker
to repeatedly access the systems. This repeated access is used to infect systems
with new malware, using them as “zombies” in coordinated denial of service
attacks, or to run any code a hacker may wish to run.
● E-mail address theft. E-mail addresses harvested from infected systems are used
by malware programs to forward themselves to other victims and malware authors
also may collect them. Malware authors can then use the addresses to send new
malware variants, barter them with other malware authors for tools or virus source
code, or sell them to others interested in using them to produce spam mail.
● Embedded e-mail engines. E-mail is the primary means for malware propagation.
Many forms of malware now embed an e-mail engine to enable the malicious
code to propagate much more quickly and with less likelihood of creating
unusual activity that can be easily detected. Illicit mass-mailers now exploit
backdoors in infected systems to capitalize on these opportunities to use such email
engines. As a result, it is believed the majority of spam produced last year
was sent via such infected systems.
● Exploiting product vulnerabilities. Malware is capitalizing more frequently on
product vulnerabilities to propagate, which enables the malicious code to spread
much faster."
