Note

your website issues might stem from your isp wanting you to just be a consumer. i think most routers are set up to automatically reject incoming connections that aren't replies to outgoing ones. adding dynamic ip to the mix means you have to guess the website's ip and the port the router is mapping the host to simultaneously with the host sending something out. and then the router blocks you anyways because the return addresses don't match. i hate it because it means i can't make distributed hosted multiplayer games without a central routing server (which totally defeats the purpose of "distributed").

i have already ran a server on my network before, it was able to do any protocol i needed (ssh, http, ftp ...) and i am still forwarding port 80, it simply isn't available to any other computer on the network and so im guessing that its an issue where it isn't able to form a connection

also virgin media doesn't do that stuff as far as i know it only blocks a few ports, also mDNS seems to work on my network (i have connected to *.local servers i have ran before)

iptables: Understanding the Core Concepts Overview of iptables: Iptables stands as a cornerstone tool for controlling firewalls on Linux systems. Operating directly with the Linux kernel for packet filtering, iptables provides a versatile but verbose interface.

Organizational Structure: The organizational structure of iptables involves tables, chains, rules, and targets. Three primary tables — filter, nat, and mangle — categorize rules. The filter table manages incoming and outgoing packets, nat facilitates Network Address Translation (NAT), and mangle is employed for advanced packet alteration.

Default Policies and Rule Creation: By default, iptables adds rules to the filter table, with default policies for INPUT, OUTPUT, and FORWARD chains set to ACCEPT. Security best practices recommend setting at least FORWARD and INPUT policies to DROP. Loopback interface access is usually allowed, and established or related connections are accepted.

Example Rules for Common Protocols: Allowing HTTP and HTTPS traffic: sudo iptables -A INPUT -p tcp — dport 80 -j ACCEPT sudo iptables -A INPUT -p tcp — dport 443 -j ACCEPT Allowing SSH traffic for remote access: sudo iptables -A INPUT -p tcp — dport 22 -j ACCEPT Common iptables Options: Iptables provides various options for rule management, including -A or –append, -I or –insert, -D or –delete, -P or –policy, -j or –jump, -s or –source, -d or –destination, -p or –protocol, -i or –in-interface, -o or –out-interface, –sport or –source-port, –dport or –destination-port, and -m or –match.

Advanced Features in iptables: Iptables offers advanced features such as NAT, interface bonding, TCP multipath, and more, making it a versatile tool for complex network configurations.

nftables: The Next Generation Firewall Overview of nftables: Nftables emerges as a user-friendly alternative to iptables, offering a more logical and streamlined structure. While positioned as a replacement for iptables, both tools coexist in modern systems.

Organizational Structure in nftables: Nftables adopts a logical structure comprising tables, chains, rules, and verdicts. It simplifies rule organization with various table types, including ip, arp, ip6, bridge, inet, and netdev.

Setting Default Policies and Example Rules: sudo nft add rule ip filter input drop sudo nft add rule ip filter forward drop sudo nft add rule ip filter input iifname “lo” accept sudo nft add rule ip filter input ct state established,related accept sudo nft add rule ip filter input tcp dport {80, 443} accept sudo nft add rule ip filter input tcp dport 22 accept Common nftables Options: Nftables options include add, insert, delete, chain, ip saddr, ip daddr, ip protocol, iifname, oifname, tcp sport, tcp dport, and ct state.

nftables vs iptables: While nftables provides a more streamlined approach, both tools coexist, allowing users to choose based on preferences and familiarity.

ufw: Simplifying Firewall Management Overview of ufw: Uncomplicated Firewall (ufw) serves as a frontend for iptables, offering a simplified interface for managing firewall configurations. It is designed to be user-friendly and automatically sets up iptables rules based on specified configurations.Ufw not only simplifies iptables but also integrates well with applications and services. Its simplicity makes it an ideal choice for those who want a quick setup without delving into intricate firewall configurations. Moreover, ufw supports application profiles, allowing users to define rules specific to applications.

Enabling ufw and Example Rules: sudo ufw enable sudo ufw allow 80/tcp sudo ufw allow 443/tcp sudo ufw allow 80,443/tcp Checking ufw Status: sudo ufw status firewalld: Dynamic Firewall Configuration Overview of firewalld: Firewalld streamlines dynamic firewall configuration, featuring zones to declare trust levels in interfaces and networks. It comes pre-installed in distributions like Red Hat Enterprise Linux, Fedora, CentOS, and can be installed on others.Firewalld excels in dynamic environments where network configurations change frequently. Its zone-based approach allows administrators to define different trust levels for various network interfaces.

Opening Ports with firewalld: sudo firewall-cmd — add-port=80/tcp — permanent sudo firewall-cmd — add-port=443/tcp — permanent sudo firewall-cmd — add-port=80/tcp — add-port=443/tcp — permanent sudo firewall-cmd — reload sudo firewall-cmd — list-ports Conclusion: Linux firewalls, comprising iptables vs ufw, nftables and firewalld, offer robust defense mechanisms for network security. While iptables and nftables cater to experienced users, ufw and firewalld provide simplified interfaces for ease of use. The choice of tools depends on user expertise and specific requirements, ensuring a secure and well-managed network environment.

VPN server port requirements

When setting up a Virtual Private Network (VPN), understanding the server port requirements is crucial for ensuring smooth and secure connectivity. Ports act as communication endpoints for networked devices, and configuring them correctly is essential for the VPN to function optimally.

Typically, VPN protocols utilize specific ports for different types of traffic. For instance, the widely used OpenVPN protocol commonly employs port 1194 for UDP traffic and port 443 for TCP traffic. UDP (User Datagram Protocol) is preferred for its speed and efficiency in transmitting data, while TCP (Transmission Control Protocol) is favored for its reliability, especially in situations where network congestion or packet loss is a concern.

Additionally, other VPN protocols like L2TP/IPsec and IKEv2/IPsec rely on different port configurations. L2TP/IPsec typically uses UDP port 500 for the initial key exchange and UDP ports 4500 and 1701 for the actual data transmission. IKEv2/IPsec, on the other hand, commonly operates over UDP port 500 and uses UDP port 4500 for NAT traversal.

It's worth noting that some networks may have restrictions or firewalls in place that block certain ports. In such cases, it may be necessary to configure the VPN to use alternative ports that are allowed by the network infrastructure.

Furthermore, for enhanced security, VPN servers often support port forwarding, allowing traffic to be directed through specific ports to specific destinations within the network. This feature enables users to access services on their private network securely from remote locations.

In conclusion, understanding VPN server port requirements is essential for ensuring compatibility, security, and optimal performance. By configuring the appropriate ports and protocols, users can establish reliable and secure connections to their VPN servers, enabling seamless access to resources from anywhere in the world.

Shell

Manpage

Most of Unix systems are managed by using Shell. Just as you need to know a minimum number of words to have a discussion in a language, you need to know a minimum number of commands to be able to easily interact with a system. Unix systems all have, sometimes with slight differences, the same set of commands. While it is not too hard to remember commands, it might be hard to remember all of their options and how exactly to use them. The solution to this is the man command. Let’s go through a part of the ssh one, as there are few elements to know to be able to read a man page:

NAME ssh — OpenSSH SSH client (remote login program) SYNOPSIS ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11] [-i identity_file] [-L [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-Q cipher | cipher-auth | mac | kex | key] [-R [bind_address:]port:host:hostport] [-S ctl_path] [-W host:port] [-w local_tun[:remote_tun]] [user@]hostname [command] DESCRIPTION ssh (SSH client) is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP ports can also be forwarded over the secure channel.

Some tips:

The NAME will summarize what the command is doing. As it is usually super short, you might want to look at DESCRIPTION (bellow) if ever it does not gives clear enough information

The SYNOPSIS will help you to understand the structure of the command:

A shell command usually have this format: command options parameters

Options inside [] are optional

The string without [] are mandatory

ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-D [bind_address:]port]

ssh is mandatory

-1246AaCfgKkMNnqsTtVvXxYy is optional

-D [bind_address:]port is optional (with bind_address: being itself optional within -D [bind_address:]port

Commands

Here is the (non-exhaustive) list of commands & concepts you should master to be verbose with Unix systems:

awk # pattern scanning and processing language basename # strip directory and suffix from filenames bg # resumes suspended jobs without bringing them to the foreground cat # print files cd # change the shell working directory. chmod # change file mode chown # change file owner and group crontab # maintain crontab files curl # transfer a URL cut # remove sections from each line of files date # display or set date and time dig # DNS lookup utility df # report file system disk space usage diff # compare files line by line du # estimate file space usage echo # display a line of text find # search for files in a directory hierarchy fg # resumes suspended jobs and bring them to the foreground grep # print lines matching a pattern kill # send a signal to a process less # read file with pagination ln # create links ls # list directory contents lsb_release # print distribution-specific information lsof # list open files mkdir # create mv # move files nc # arbitrary TCP and UDP connections and listens netstat # print network connections, routing tables, interface statistics... nice # execute a utility with an altered scheduling priority nproc # print the number of processing units available passwd # change user password pgrep # look up processes based on name and other attributes pkill # send signal to processes based on name and other attributes printenv # print all or part of environment pwd # print name of current/working directory top # display Linux processes tr # translate or delete characters ps # report a snapshot of the current processes rm # remove files or directories rmdir # remove directories rsync # remote file copy scp # secure copy (remote file copy program) sed # stream editor for filtering and transforming text sleep # suspend execution for an interval of time sort # sort lines of text file ssh # OpenSSH SSH client (remote login program) ssh-keygen # SSH key generation, management and conversion su # substitute user identity sudo # execute a command as another user tail # output the last part of files tar # manipulate archives files tr # translate or delete characters uname # Print operating system name uniq # report or omit repeated lines uptime # show how long system has been running w # Show who is logged on and what they are doing whereis # locate the binary, source, and manual page files for a command which # locate a command wc # print newline, word, and byte counts for each file xargs # build and execute command lines from standard input | # redirect standard output to another command > # redirect standard output < # redirect standard input & # send process to background

SSH Penetration Testing: A Comprehensive Guide

Welcome to our comprehensive guide on SSH Penetration Testing. In this blog post, we will delve into the technical aspects of SSH Pentesting, providing you with valuable insights and strategies to ensure the security of your systems. Let's get started with this in-depth exploration of SSH Penetration Testing. Welcome, today I am writing about SSH Penetration Testing fundamentals describing port 22 vulnerabilities. SSH security is one of the topics we all need to understand, remote access services can be an entry point for malicious actors when configured improperly. SSH IntroductionManaging SSH Service SSH Interesting Files SSH Authentication Types SSH Hacking Tools 1. SSH EnumerationSSH Banner Grabber SSH Servers List Detect SSH Authentication Type Detect remote users 2. SSH ExploitationBruteforce SSH Service Crack SSH Private Keys Default Credentials SSH Bad Keys SSH Exploits SSH and ShellShock Openssh 8.2 p1 exploit 3. SSH Post Exploitation - Pentest SSHSSH Persistence SSH Lateral Movement Search SSH Key files Search SSH Key files inside file content SSH Hijacking F.A.QWhat is SSH Penetration Testing? What are the standard SSH Penetration Testing techniques? What is the purpose of SSH Penetration Testing? Can SSH Penetration Testing be performed without permission? What should be done after SSH Penetration Testing? How do I test my SSH connection? Is SSH port vulnerable? What is the vulnerability of port 22? SSH Introduction Understanding how SSH works is out of scope, Here I assume you are already familiar with the service and how can be configured on a Linux host. Some things to remember, SSH works on port 22 by default and uses a client-server architecture, which is used to access remote hosts securely. SSH Penetration Testing Fundamentals SSH can implement different types of authentication each one of them has its security vulnerabilities, keep that in mind! One of the most used methods to authenticate is using RSA Keys using the PKI infrastructure. Another great feature is the possibility to create encrypted tunnels between machines or implement port forwarding on local or remote services, or as a pentester, we can use it to pivot inside the network under the radar since SSH is a well-known tool by sysadmins. Managing SSH Service Verify SSH Server Status systemctl status ssh Start SSH Service systemctl start ssh Stop SSH Service systemctl stop stop Restart SSH Service systemctl restart stop Define SSH server to start on boot systemctl enable ssh SSH Interesting Files When performing SSH penetration testing, several interesting files may contain sensitive information and can be targeted by an attacker. Client Config SSH client configuration file can be used to automate configurations or jump between machines, take some time and check the file: vi /etc/ssh/ssh_config Server Config This file contains the configuration settings for the SSH daemon, which can be targeted for configuration-based attacks. vi /etc/ssh/sshd_config Recommendation: Active tunnel settings and agent relay, help you with lateral movement. Authorized Keys This file contains the public keys that are authorized to access a user's account, which can be targeted by an attacker to gain unauthorized access. vi /etc/ssh/authorized_keys Known Hosts cat /home/rfs/.ssh/known_hosts RSA Keys Default folder containing cd ~/.ssh cd /home/rfs/.ssh SSH Authentication Types Authentication TypeDescriptionPassword AuthenticationUsers enter a password to authenticate. This is the most common method but may pose security risks if weak passwords are used.Public Key AuthenticationUses a pair of cryptographic keys, a public key, and a private key. The public key is stored on the server, and the private key is kept securely on the client. Offers strong security and is less susceptible to brute-force attacks.Keyboard-Interactive AuthenticationAllows for a more interactive authentication process, including methods like challenge-response. Often used for multi-factor authentication (MFA) where users need to respond to dynamic challenges.Host-Based AuthenticationAuthenticates based on the host system rather than individual users. It relies on the client system's host key and the server's configuration. This method is less secure and not widely recommended.Certificate-Based AuthenticationInvolves using two or more authentication methods, such as a combination of passwords, biometric data, or a security token. Provides an extra layer of security to ensure the authenticity of the user.Multi-Factor Authentication (MFA)Involves using two or more authentication methods, such as a combination of password, biometric data, or a security token. Provides an extra layer of security to ensure the authenticity of the user.SSH Authentication Types Ok, let's talk about how to pentest SSH, As you know it all starts with enumeration we can use some tools to do all the work for us or we can do it manually. Some questions to ask before starting to enumerate - Is there any SSH server running? - On what Port? - What version is running? - Any Exploit to that version? - What authentication type is used? Passwords / RSA Keys - It is blocking brute force? After we have all the answers we can start thinking about what to do, If don't have any information about users or passwords/keys yet is better to search for an exploit, unfortunately, SSH exploits are rare, Search my website if there are any exploits. Damn it, we are stuck :/ It's time to go enumerate other services and try to find something that can be used like usernames or RSA Keys, remember Keys usually have the username at the bottom. Assuming we found one or more usernames we can try to brute force the service using a good wordlist or if we were lucky and have found an RSA Key with a username, We Are In! Haha is not so easy, but OK, we are learning... SSH Hacking Tools Tool NameDescriptionUsageHydraPassword cracking tool for various protocols, including SSHBrute-force attacks on SSH passwordsNmapNetwork scanning tool that can identify open SSH portsUsed for reconnaissance on target systemsMetasploitFramework with various modules, including those for SSH exploitationExploiting vulnerabilities in SSH servicesJohn the RipperPassword cracking tool for various password hashesUsed to crack SSH password hashesWiresharkNetwork protocol analyzerCaptures and analyzes SSH trafficSSHDumpSniffing tool for capturing SSH trafficMonitors and captures SSH packetsSSH Hacking tools 1. SSH Enumeration During the enumeration process, cybersecurity professionals seek to gather details such as active SSH hosts, supported algorithms, version information, and user accounts. This information becomes instrumental in performing a thorough security analysis, enabling practitioners to identify potential weaknesses and implement necessary measures to fortify the SSH implementation against unauthorized access and exploitation. After we scan a network and identify port 22 open on a remote host we need to identify what SSH service is running and what version, we can use Nmap. nmap -sV -p22 192.168.1.96 SSH Banner Grabber Banner grabbing is an easy technique to do but can help us a lot, we can verify what service version is running on the remote server and try to find a CVE related to it. Banner grabbing can be useful for several reasons, including: - Identifying the version and type of SSH server: This information can be used to determine if the SSH server is vulnerable to known exploits or if there are any known security issues with the version of the software being used. - Checking for compliance with organizational security policies: Administrators may want to ensure that all SSH servers in their organization are configured to display a standard banner message that includes specific information. - Verifying the authenticity of an SSH server: Banner messages can be used to verify that the SSH server being accessed is the intended one, rather than a fake or rogue server. Several tools can be used for SSH banner grabbing, such as Nmap, Netcat, and SSH-Banner. These tools connect to an SSH server and retrieve the banner message. The retrieved banner can then be analyzed to determine the information that is being displayed. nc 192.168.1.96 22 If we try to connect using the verbose parameter we can check all the information necessary to authenticate on the remote server. ssh -v 192.168.1.96 SSH Servers List SSH ServerDescriptionURLOpenSSHOpen-source SSH server widely used in Unix-like operating systemsOpenSSHDropbearLightweight and efficient SSH server primarily designed for embedded systemsDropbearBitvise SSH ServerSSH server for Windows with additional features like remote administrationBitviseTectia SSH ServerCommercial SSH server solution by SSH Communications SecurityTectiaProFTPD with mod_sftpFTP server with SFTP support using mod_sftpProFTPDSSH Servers List Detect SSH Authentication Type To detect the SSH authentication type being used to access a system, you can examine the system logs. The authentication type will be logged when a user authenticates to the system via SSH. Here's how you can check the SSH authentication type on a Linux system: - Open the system log file at /var/log/auth.log using your preferred text editor. - Search for the line that contains the user login information you want to check. - Look for the "Accepted" keyword in the line, which indicates that the authentication was successful. ssh -v 192.168.1.96 SSH authentication types Detect remote users msfconsole msf> use auxiliary/scanner/ssh/ssh_enumusers 2. SSH Exploitation At this point, we only know what service is running on port 22 and what version it has (OpenSSH_4.7p1 Debian-8ubuntu1), assuming we have found the username msfadmin we will try to brute-force his password using hydra.
