Please note that the hackers are clever guys but it is possible to protect your
computer from them too.
When a hacker developed the special software he needs to install this software onto your
computer but this task is not easy!
Ways to install hacker's software:
1. CD, flashes, diskettes, DVD, and so on. Please be careful with them.
2. E-mails messages can contain the worms. Please do not run exe or other file from e-mail
software. First, save it and check out it by anti-virus software. Please note than picture
of music file can contain a worm.
Please note that e-mail software may contain the bugs allowing running any file without
your prompt. In this case you can try Fes Emailer. It has
no the tools to run an active content.
3. If you have on your PC installed a server (such as FTP), please be careful with it. If
you do not need the server, please stop it as this server may listen some port. In this
case a hacker can attack this port using the exploit and install his software on your PC.
To prevent it please regularly update your Internet software. The second way is to use a
firewall. But after you have installed a firewall, please try to scan your PC ports to
find open ones. Please find "online port scanner". But online scanners scan only
main ports. To scan all ports, you can install a port scanner onto your PC. Please note
that a PC has 65535 TCP ports and 65535 UDP ports. You may need to scan all these ports.
Please note that if you close all your ports, then any hacker cannot install his software
onto your PC using your PC ports. Please note also that a firewall allows for you to work
with all your ports, but a hacker cannot use your ports.
4. Please be careful with shared files and printers. This is very danger. Please do not
allow shared files or printers on your PC if you do not need them or use long passwords.
5. The hackers also can attack your PC when you visit their web sites. Please disable all
active content when you visit unknown web sites: JavaScript, java, activex. We think that
the safest browser is Mozilla Firefox. Additionally, you can install 'Noscript' add-in. This add-in allows blocking any active
content for untrusted sites. It also can disable iframe and frame tags. New attack is based on using xml pages. In this case, Noscript does not allow arbitrary code execution but it can't protect from browser crash if you not updated it. Also, the Noscript can't help if your trusted site was hacked.
But the hackers can attack your browser and it can begin to run any active content without
any prompt. So can try to use Fes Emailer. This program
downloaded the Internet page, physically removes any active content from it, and saves
this page to a file, run your default browser to open this file. This is very powerful
defense against any active content.
Please note that if you started to use this software, please do not enable active content
features of your web browser too. This is additional defense.
Also it is very important to encode your e-mails. Please note that the hackers can decode
the e-mails saved by many popular e-mail programs.
In this case you can use the Fes Emailer. It encodes all
e-mails with 2048-bit key. You can use many long keys. This is a good defense against
hackers.
Please note also that the hackers can decode your important files, such as MS Excel, MS
words and so on. In this situation you can encode your files with, for example, PGP
software. Additionally, this software can encode your output e-mails before sending. But
if you want only to encode your text files, then you can use a text editor of Fes Emailer. This editor allows encoding your text with
2048-bit key. This is good defense against hackers.
