🦑Secure your linux first Network Filtering-Use netfilter-iptables to configure a firewall for Linux Part 1 full
netfilter / iptables is Integrated IP packet filtering system for the latest 2.4.x version of the Linux kernel(old and stable version)

> If the Linux system is connected to the Internet or a LAN, a server, or a proxy server that connects to the LAN and the Internet, the system facilitates better control of IP packet filtering and firewall configuration on the Linux system

> undercode will introduce the netfilter / iptables system, how it works, its advantages, installation and configuration, and how to use it to configure a firewall on a Linux system to filter IP packets.
twitter.com/UndercOdeTC

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Among Linux packet filtering solutions such as ipfwadm and ipchains, the netfilter / iptables IP packet filtering system is the latest solution and the first solution integrated into the Linux kernel.

2) Netfilter / iptables system for Linux system
administrators, network administrators, and home users who want to configure a firewall based on their specific needs, save money on firewall solutions, and have full control over IP packet filtering Very ideal.

3) Understand firewall configuration and packet filtering
For Linux systems connected to the network, a firewall is an essential defense mechanism. It only allows legitimate network traffic to enter and leave the system, and prohibits any other network traffic.

4) To determine whether network traffic is legitimate, the firewall relies on a set of rules it contains that are predefined by the network or system administrator. These rules tell the firewall whether certain traffic is legitimate and what to do with network traffic from a source, a destination, or a protocol type. The term "configure firewall" means adding, modifying, and removing these rules. I will discuss these rules in detail later in undercode grps

5) Network traffic consists of IP packets (or packets for short) —small pieces of data that are transmitted in a stream from the source system to the destination system. These packets have headers, which are data bits that accompany each packet and contain information about the source, destination, and protocol type of the packet.

6) The firewall checks these headers against a set of rules to determine which packets to accept and which packets to reject. We call this process packet filtering.

🦑Why configure your own firewall on kernel linux ?
instagram.com/UndercOdeTestingCompany

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) For various reasons and reasons, you need to configure your firewall based on your specific needs. Perhaps the most important reason is security.

2) Administrators may want their firewall to be able to prevent unauthorized sources from accessing their Linux systems, such as through Telnet. They may also want to restrict network traffic to and from their systems so that only traffic from trusted sources can enter their systems, and only authorized traffic can go out. Home users may configure the firewall to a lower security level by allowing all outbound packets to pass through.

3) Another reason behind this is that bandwidth can be saved by blocking excess traffic from sources like advertising sites.

4) Thus, the firewall configuration can be customized to meet any specific needs and any security level needs. This is where the netfilter / iptables system comes in.

🦑 How does the netfilter / iptables system work?

1) netfilter / iptables IP packet filtering system is a powerful tool for adding, editing, and removing rules. These rules are rules that the firewall follows and composes when making packet filtering decisions.

2) These rules are stored in dedicated packet filtering tables, which are integrated in the Linux kernel. In the packet filtering table, rules are grouped into what we call a chain. I will discuss these rules in detail and how to build them and group them in chains.

3) Although the netfilter / iptables IP packet filtering system is called a single entity, it actually consists of two components, netfilter and iptables.

4) The netfilter component, also called kernelspace, is part of the kernel and consists of some packet filtering tables. These tables contain the set of rules that the kernel uses to control packet filtering processing.

5) The iptables component is a tool, also known as userspace, that makes it easy to insert, modify, and remove rules from packet filtering tables. Unless you are using Red Hat Linux 7.1 or later, you need to download the tool from netfilter.org and install it.

6) By using user space, you can build your own custom rules that are stored in a packet filter table in kernel space. These rules have destinations that tell the kernel what to do with packets that come from some source, go to some destination, or have certain protocol types. If a packet matches the rule, the destination ACCEPT is used to allow the packet to pass. You can also use target DROP or REJECT to block and kill packets. There are many other goals for other operations that can be performed on packets.

🦑 How firewall rules acts ?
pinterest.com/UndercOdeOfficial

1) Rules can be grouped in chains based on the type of packets processed by the rules.

2) Rules for processing inbound packets are added to the INPUT chain. Rules for processing outbound packets are added to the OUTPUT chain. Rules for processing packets being forwarded are added to the FORWARD chain.

3) These three chains are the default main chains built into the basic packet filtering table. In addition, there are many other types of chains available, such as PREROUTING and POTROUTING, as well as providing user-defined chains. Each chain can have a policy that defines a "default destination", that is, the default action to be performed, which is performed when a packet does not match any rule in the chain.

4) For A linux :

Once the rules are established and the chain is in place, the real packet filtering can begin. Kernel space takes over from user space. When a packet reaches the firewall, the kernel first checks the header information of the packet, especially the destination of the packet. We call this process routing.

5)If the packet originates from the outside world and goes to the system, and the firewall is open, the kernel passes it to the INPUT chain of the kernel-space packet filtering table. If the packet originates from another source within the system or on the internal network to which the system is connected, and this packet is destined for another external system, the packet is passed to the OUTPUT chain. Similarly, packets originating from and destined for an external system are passed to the FORWARD chain.

🦑In Linux Firewalls - create your own part 2 Packet filtering process:
T.me/UndercOdeTesting

🦑LETS START:

> Before Installation Before starting to install the iptables userspace tool, you need to make some modifications to the system. First, you need to use the make config command to configure kernel options. During configuration, they must be turned on by setting the CONFIG_NETFILTER and CONFIG_IP_NF_IPTABLES options to Y, as this is required to make netfilter / iptables work. Here are other options you might want to turn on:

1) CONFIG_PACKET: This option is useful if you want applications and programs to use certain network devices directly.
CONFIG_IP_NF_MATCH_STATE: This option is very important and useful if you want to configure a stateful firewall. This type of firewall remembers previous decisions about packet filtering and makes new decisions based on them. I will discuss this further in the advantages section of the netfilter / iptables system.

2) CONFIG_IP_NF_FILTER: This option provides a basic packet filtering framework. If this option is turned on, a basic filter table (with built-in INPUT, FORWARD, and OUTPUT chains) is added to kernel space.
CONFIG_IP_NF_TARGET_REJECT: This option allows you to specify that ICMP error messages should be sent in response to inbound packets that have been dropped by DROP, rather than simply killing them.
Now you are ready to install this userspace tool.

🦑 Install the userspace tools :
> After downloading the source code for the iptables userspace tools (it's similar to iptables-1.2.6a.tar.bz2), you can begin the installation. You need to log in as root to perform the installation. Listing 1 shows an example that indicates the commands required to install the tool, their necessary order, and their descriptions.

1) Listing 1. Example of userspace tool installation
First, unpack the tool package into a directory:

# bzip2 -d iptables-1.2.6a.tar.bz2
# tar -xvf iptables-1.2.6a.tar

2) This will unpack the tool source into a directory named iptables-1.2.6a.
Now change to the iptables-1.2.6a directory:

# cd iptables-1.2.6a

3) The INSTALL file in this directory contains a lot of useful information
on compiling and installing this tool.

4) Now compile the userspace tool using the following command:

# make KERNEL_DIR = / usr / src / linux /

5) Here the KERNEL_DIR = / usr / src / linux / specifies the path to the kernel's
directory. If the directory of kernel happens to be different on some
systems, the appropriate directory path should be substituted for
/ usr / src / linux.

6) Now install the source binaries using the following command:

# make install KERNEL_DIR = / usr / src / linux /

> Now the installation is complete.

🦑For apps developpers > How to strengthen Android apk to prevent cracking (prevent reverse compilation) ? by Undercode :
T.me/UnderCodeTesting

🦑LETS START:


> Now the main tool is to contact the SDK. In order to prevent game packages from being cracked and compiled, and to discover encrypted strings, let me share the following points:
There are four main ways to implement anti-cracking technology:

1) ProGuard technology

2) Signature ratio For technology

3) NDK .so dynamic library technology

4) Dynamic loading technology

5) Third-party platform encryption and detection of vulnerabilities

🦑 How to decompile and encrypt the apk package in Android Security so knowledge points by undercode

1) The first one: Code obfuscation technology (ProGuard) This technology is mainly used to obfuscate the code and reduce the readability of the code after reverse compiling. However, this technology cannot prevent the packing technology from packing (adding codes such as fees, advertisements and viruses) And, as long as a careful person, the code can still be analyzed in reverse, so the technology does not solve the problem of cracking, but only increases the difficulty of cracking.

2) Second: Signature comparison technology This technology mainly prevents the packing technology from packing, but the risk of reverse analysis of the code still exists. And this technology cannot solve the problem of being packed at all. If the cracker commented out the signature comparison code and compiled it back, the technology would be cracked.

3) The third: NDK .so dynamic library technology. This technology implements all important core code in C files, and uses NDK technology to compile the core code into a .so dynamic library, which is then called by JNI. Although this technology can protect the core code, the risk of being packed still exists.

4) The fourth type: dynamic loading technology, which is a relatively mature technology in Java, but this technology in Android has not been fully utilized by everyone.

5) Fifth type: use of third-party platforms

🦑 The fourth method is mainly explained. This technology can effectively prevent problems such as reverse analysis, being cracked, and being packed. The dynamic loading technology is divided into the following steps:

a) Jar package that compiles the core code into a dex file

b) Encrypting the jar package
Decrypt with NDK at the main entrance of the program
Then use ClassLoader to dynamically load the jar package
Use reflection technology to set ClassLoader as the system's ClassLoader.

🦑 The main advantages are:

1) The core code is in the encrypted jar, so the cracker cannot extract the class file. If the encryption key is obtained by the cracker, it will be another level of security.

2) This technology can also effectively prevent the shelling technology. The code is dynamically loaded. The cracker's shell program cannot be added to the encrypted jar package. The cracker injected the shell program entry in time.

3) The shell program is not in the ClassLoader jar package. Therefore, it cannot be executed unless the cracker replaces the ClassLoader jar package and turns off the NDK decryption code. However, this installation on the phone is no longer our application, and the user must uninstall it.

4) Therefore, when compared, the fourth dynamic loading technology is the safest, but the efficiency is not strictly tested. After a rough experiment, the efficiency has not been significantly reduced.

If there is only one computer, it will be miserable. Install two operating systems. , Restart, switch operating system.

🦑LETS START:

> Here is a software that can solve this problem. The same source code under Windows is
compiled and debugged with VC and gcc at the same time. It is cygwin. I use vc6.0, gcc2.95.2.

1) Install cygwin
First install cygwin. Cygwin is a cygnus.com product. Download it from its website and
install it directly on the Internet. Do n’t forget to select the gcc option during installation.

2) Code directory
My code directory is ZCore. The following are subdirectories. There are two subdirectories in the subdirectory Build:
VC and gcc hold the VC project files and gcc Makefile respectively; the subdirectory Src is the code directory; the
subdirectory Doc In the code is the Readme and other instructions (not used to Chinese comments in English code), the code
To be compiled into a static library. Needless to say the VC compilation environment, let's see how to set up a gcc compilation environment.
Makefile has to be written by myself, there is no Makefile auxiliary tool in my cygwin. Run cygwin.

3) Mapping the directory
We first mount the win32 directory into the posix directory, and run mount to view the original
mounted path. The path of my ZCore is: d: studyzcore, I want to map into / zcore, the
command is: "mount d: / study / zcore / zcore". There is a warning, but no problem. Now
using mount to view, there is one more. This information is stored in the registry
[HKEY_CURRENT_USERSoftwareCygnus SolutionsCygwinmounts v2 / zcore]
If you want to uninstall, use the command "umount / zcore".

4) gcc compile
with "cd / zcore / build / gcc" into the compilation directory, make it.

In this way, you can use VC to compile with gcc when debugging code, and it will be easier to migrate to other environments in the future.

🦑 HOW TO LOAD IFRAMES IN YOUR MODULES ?


> If you have used one or more modules you must have seen the iframes used for realtime result display. In this tutorial I'm going to show you how to insert them into your module and how they function.

> We need and a bit of php code in order to get started and a screen file that spits out the content.

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) The start of your index.php file in your module should look like this:

<?php
if(!defined('IN_SCRIPT')){
exit;
}
// iframe that shows attack
$_CONTEXT['screen'] = array();
$_CONTEXT['screen']['src'] = $_PATHS['module_default_root_http']."/screen.php";
$_CONTEXT['screen']['w'] = 800;
$_CONTEXT['screen']['h'] = 200;
$_CONTEXT['screen']['name'] = "screen";
?>

2) You can however place the context variable anywhere in your code as long as you put it before your html form.

> In case you don't understand what the context variable is about, here's some explanation:

a) src: source of the iframe

b)w: width of the iframe

c)h: height of the iframe

e) name: name of the iframe

🦑 The start of the module with all code would look like this:

<?php
if(!defined('IN_SCRIPT')){
exit;
}
// iframe that shows attack
$_CONTEXT['screen'] = array();
$_CONTEXT['screen']['src'] = $_PATHS['module_default_root_http']."/screen.php";
$_CONTEXT['screen']['w'] = 800;
$_CONTEXT['screen']['h'] = 200;
$_CONTEXT['screen']['name'] = "screen";
$sCode = (isset($sCode) ? $sCode : "");
$sCode .= " <div class=\"moddesc\"><img src=\"./".$_CONTEXT['module_current']."/".$_CONTEXT['module_current'].".png\" width=\"90\" align=\"left\" /><h2>".$_CONTEXT['modules'][$_CONTEXT['module_current']]['name']."</h2>".$_CONTEXT['modules'][$_CONTEXT['module_current']]['description']."</div>\n";
$sCode .= "<form method=\"post\" action=\"".$_CONTEXT['screen']['src']."\" target=\"".$_CONTEXT['screen']['name']."\">\n";
?>

> You can copy the code above for any module you want to create that requires usage of iframes.

🦑Create Your First HackSuite Tutorial by UnderCode :
T.me/UndeCodeTesting

1) In this small tutorial we are going to create a new app for the hacksuite. We're not going to do anything fancy here, we will make a simple app to get familiar how to write compatible scripts for the suite.

2) We are going to create a tool that allows you to get the profile page of a facebook image name..
See this example :

🦑The bold part is the profile id we want, there's a 1001 ways to isolate it but I'll do it the lazy way:

<?php
$sInput = "http://sphotos-a.ak.fbcdn.net/hphotos-ak-prn1/396991_258579564204685_1706121139_n.jpg";
$aInput = @explode("_",$sInput);
if(false==($iInput = @count($aInput))){
die("Invalid facebook image");
}
if(!isset($aInput[$iInput-1]) || $aInput[$iInput-1]!="n.jpg" || !is_numeric($aInput[$iInput-3])){
die("Invalid facebook image, wrong structure");
}
echo"http://www.facebook.com/profile.php?id=".$aInput[$iInput-3];
?>

🦑 This will produce the facebook profile url of where the image originally comes from.

> Of course this is not very useful unless the user can input any url through a form:

<?php
if(!isset($_POST['submit'])){
echo"<form method=\"post\">";
echo"<input type=\"text\" name=\"sUrl\"> <input type=\"submit\" name=\"submit\">";
echo"</form>";
}
else{
$aInput = @explode("_",$_POST['sUrl']);
if(false==($iInput = @count($aInput))){
die("Invalid facebook image");
}
if(!isset($aInput[$iInput-1]) || $aInput[$iInput-1]!="n.jpg" || !is_numeric($aInput[$iInput-3])){
die("Invalid facebook image, wrong structure");
}
echo"http://www.facebook.com/profile.php?id=".$aInput[$iInput-3];
}
?>

🦑 To get started with creating your application click on development and then create new app:

1) name of app: give the app unique names like 'AppName', you can't use

2) names that have this pattern (thc_xx)

3) location: relative location from the hacksuite root folder, eg

4) MyAppFolder/Start, you can't use locations that have this pattern (thc_xx)

5) version: typically applications in the hacksuite start at 0.0.1, you can however use any version

6) When you submit the form, a new form will appear

7) Replace the line echo world with the code above(of course without the php open and close tag), submit the form and you created your first - not so fancy - hacksuite application. You would still need to put some styling and other html but this is just a POC.

🦑How Identify System Fingerprint Information undercode tutorial
pinterest.com/UnderCodeOfficial

🦑LETS START:

1) Use the -O option of the Nmap command to enable the operating system testing function. The execution command is as follows:

> root@kali:~# nmap -O 192.168.41.136

2) Starting Nmap 6.40 ( http://nmap.org )
Nmap scan report for www.example site... (192.168.xx.xxx)
Host is up (0.00045s latency).
Not shown: 996 closed ports
PORT STATE SERVICE
22/tcp open ssh
53/tcp open domain
80/tcp open http
111/tcp open rpcbind

> MAC Address: 00:0C:29:31:02:17 (VMware) //MAC地址
Device type: general purpose
Running: Linux 2.6.X|3.X
OS CPE: cpe:/o:linux:linux_kernel:2.6 cpe:/o:linux:linux_kernel:3

OS details: Linux..version xx
Network Distance: 1 hop

2) OS detection performed. Please report any incorrect results at http://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 2.18 seconds

3) The output information shows the fingerprint information of the host 192.168.xx.xxx, including the port opened by the target host, the MAC address, the operating system type, and the kernel version.

🦑 Fingerprint recognition tool p0f :

> p0f is a 100% passive fingerprint recognition tool. The tool analyzes the data packets sent by the target host to identify the operating system on the host, even if a good-performance firewall is installed on the system. The main identifying information of p0f is as follows:

> Operating system type;
port;

1) Whether it is running behind a firewall;

2) Whether to run in NAT mode;

3) Whether to run in load balancing mode;

4) Remote system has been started;

5) DSL and ISP information for remote systems.

6) Use p0f to analyze a file captured by Wireshark. The execution command is as follows:
