Kali Linux is probably the most well-known hacking distribution among penetration testers. However, there are alternative distros which offer versatility and advanced package management systems that are absolutely worth considering.
Web applications are becoming more and more popular, replacing traditional desktop programs at an accelerated rate. With all these new apps out on the web comes various security implications associated with being connected to the internet where anyone can poke and prod at them. One of the simplest, yet the most prevalent types of security flaws found in modern web apps are SQL injections.
Step 1: What Exploit Development Is and Why Should I Be Interested on About This Topic
Did you know Kali 1.0.8? You probably did, and you probably know about the EFI boot option that has been added.
A man-in-the-middle attack, or MitM attack, is when a hacker gets on a network and forces all nearby devices to connect to their machine directly. This lets them spy on traffic and even modify certain things. Bettercap is one tool that can be used for these types of MitM attacks, but Xerosploit can automate high-level functions that would normally take more configuration work in Bettercap.
Microsoft's built-in antimalware solution does its best to prevent common attacks. Unfortunately for Windows 10 users, evading detection requires almost no effort at all. An attacker armed with this knowledge will easily bypass security software using any number of tools.
Python is commonly touted as one of the best programming languages for beginners to learn, and its straightforward syntax and functionality makes that hard to argue with. But a lot of tutorials still use Python 2, which is outdated now. Python 3 introduces many new features, and it's important to be aware of them going forward, as well as the key differences between Python 3 and its predecessor.
You've protected your Ubuntu system from physical attacks, annoyed network hackers, and sandboxed potentially malicious applications. Great! Now, the next logical steps to locking down your OS include thoroughly auditing Ubuntu for weak points, using antivirus software that respects your privacy, and monitoring system logs like a boss.
A PirateBox creates a network that allows users to communicate wirelessly, connecting smartphones and laptops even when surrounding infrastructure has been disabled on purpose or destroyed in a disaster. Using a Raspberry Pi, we will make a wireless offline server that hosts files and a chat room as an educational database, a discreet local chat room, or a dead-drop file server.
Besside-ng is the hidden gem of the Aircrack-ng suite of Wi-Fi hacking tools. When run with a wireless network adapter capable of packet injection, Besside-ng can harvest WPA handshakes from any network with an active user — and crack WEP passwords outright. Unlike many tools, it requires no special dependencies and can be run via SSH, making it easy to deploy remotely.
Once you've installed Ubuntu with security in mind and reduced the possibility of network attacks on your system, you can start thinking about security on an application level. If a malicious file is opened on your system, will an attacker be able to access every file on the computer? The chances are much slimmer if you put the proper defenses in place.
VNC is a great protocol that you can use on Windows and Linux machines to remotely control computers. This is useful if you need to control your computer when away from home, help your grandma check her email, or help a client with a disk cleanup. VNC is secure in the sense that it requires authentication in order to make the connection, but after that, the data is sent over the internet unencrypted. This means that an attacker could sniff your traffic and snoop everything that's going on. Th...
SSH is what is referred to as the Secure SHell protocol. SSH allows you to do a plethora of great things over a network, all while being heavily encrypted. You can make a remote accessible shell on your home computer that gives you access to all your files at home, and you can even tunnel all of your traffic to keep you anonymous and protected on public Wi-Fi. It has many great uses and is a must have tool for your arsenal. It was designed to replace the insecure Telnet protocol, which sends ...
Formerly ipchains, iptables is a script-based firewall that's included with both Mac and Linux operating systems. In my opinion, it's the best firewall in existence. The only downfall is that it's complicated for some people to use due to its script-based nature. But this should be disregarded, as firewalls are nearly the entire security of your computer.
Paying for web hosting isn't ideal in most situations. If you have your own website, hosting it yourself is very acceptable and easy to do, assuming your internet bandwidth permits. Most people want to run a personal site, nothing crazy, so hosting from home on low-bandwidth internet is actually a better solution in most cases.
Sharing a laptop's wireless Internet connection with other computers connected to its Ethernet port is a great skill to know. It can be good for a number of reasons; Your computer may not have proper hardware to have a standard setup, or you may have an awkward network topology where sharing your wireless Internet via Ethernet would just be a better option.
Haven't you ever wanted to live in a futuristic home? I think that homes are headed towards an era where they will be controlled by our computers and smartphones. No longer will you have to find your keys to unlock your door, or wait until you get home to monitor your security, because X10 is here.
SSL stands for Secure Socket Layer. It's an encryption standard used on most sites' login pages to avoid their users' passwords being packet sniffed in simple plain-text format. This keeps the users safe by having all of that traffic encrypted over an "https" connection. So, whenever you see "https://" in front of the URL in your browser, you know you're safe... or are you?
Remember that scene in The Matrix when Trinity uses a realistic Nmap port scan, followed by an actual SSH exploit (long since patched) to break into a power company? Well, believe it or not, but that scene is not far fetched at all. If you want to exploit vulnerabilities and root boxes, you'll need to learn how to perform the necessary reconnaissance first. In fact, you will spend far more time researching your target then you will exploiting it. In this article, I am going to show you the fi...
Reverse shells are useful for issuing commands to a remote client when the client is behind something such as a NAT. You might say, "But can't a normal shell or simple SSH tunnel do the same thing?". No, it can't. All over the internet I see a lot of confusion regarding the difference between a normal shell and a reverse shell. Let's clear this up before we get started.
Leaving your wireless router at its default settings is a bad idea. The sad thing is, most people still do it. Once they've penetrated your network, hackers will change your router settings so they'll have an easy way back in. This allows them to change your network into a shell or proxy so they can forward their traffic anonymously through you when committing other dirty deeds.
Only so much data can be passed through the network and to your computer's networking interfaces. This is limited by the amount of bandwidth you have. The more bandwidth you have, the faster your network connections will be. Not only this, but your transfers will be more parallel and distributed so that all of your speed isn't taken up by one transfer. When all of your bandwidth is sapped and unable to be used, this is called a denial of service, or a DOS.
Your IP (Internet Protocol) address is your unique ID on the internet. It's synonymous with your home address. Anyone in the world can contact your computer through its IP address, and send a retrieve information with it.
When your computer first connects to a nework, it sends out a request on the network to lease an IP from the router. The router then leases your computer an unused IP address, which is used as a unique routing address for sending traffic that is meant for you, to you. As everything tends to, this method has its flaws.
File Transfer Protocol, or FTP, is a network protocol made for transferring files in a client and host fashion over a Transmission Control Protocol (TCP) network, such as the internet. FTP is integrated into most browsers, and you have probably used it before. It is a common way to host files and transfer them easily. To access an FTP, a login is required, unless the server is configured to use anonymous logins (like the Arch Linux mirrors).
SSH is amazing, and we praise its existence on Null Byte for many reasons. Notably, it allows us to reroute our traffic through encrypted ports on our local host to be sent to its destination when on the go. You can even control your home computers remotely over a secure and encrypted connection. This is handy for a multitude of reasons.
TCP/IP Client / Server Application Hello! Today's blog post will be about coding a very rudimentary Client and Server application duo, which will communicate by using TCP Sockets.
In my Wireshark article, we talked a little bit about packet sniffing, but we focused more on the underlying protocols and models. Now, I'd like to dive right back into Wireshark and start stealing packets.
Encryped traffic and tunneling is a must when away from home to keep you and your information safe. SSH tunnels can be slow, and are heavily encrypted. VPNs are an all port solution, and proxies are just not what we need in most cases. Then, there is Tor.
Hello, fellow Null Byters. Today, with mixed feelings, I want to let you know that this is my last official post as the admin of Null Byte. I've come to the decision that I need to spend more time focusing on my studies. Over the past 5 months, I have enjoyed building this community and teaching people unorthodox methods of doing things, creating things, and hacking them. But I'm also excited to be delving deeper into the studies that brought me here in the first place.
In this article, I'll show you how to send SMS messages with Python. You'll need Python 2.7 or later, urllib and urllib2. The code basically uses an online text messaging service to "POST" html data, as if a person was entering the data themselves. The uses for something like this are unlimited. For example, I modified the basic code so I would receive a text message letting me know every time someone rang my doorbell. The program could interface with Arduino through a serial port, and send d...
Here's something fun for the Null Byte community to do—a coding competition! This week, I wanted to get everyone involved by offering you all a nice library of possible program types to choose from and try to code. At the end of this competition, all of the submitted programs will be reviewed by the community and myself. The coder that receives the most votes will be dubbed THE BEST.
After a long time I succeed to reconnect to victim's system without a touch(the victim did not click the app again)
When i went to class today, a good friend asked me a question. He wanted to know what the best hacking software was to basically do everything. What i told him was this: Well there isn't an "Ultimate" tool boot there are a number of tools which deserve a "Medal." So what i'm trying to say here... What are some of the best hacking tools available right now? For starters i created a list with some of the tools.
so in part 2 we will discuss more, liek, How to use this on windows???! And how to use the glibc function!!! Also we will discuss some other techniquez!
Google is great. They provide us with tons of free services and open source APIs that we can code fun tools for, one of which I don't think gets enough credit: Google Voice.
In the first part of this series, we learned about darknets, as well as how they came about. But these patches of forgotten Internet are not the oasis of free information you might think. Despite being hidden—or just harder to come across—these networks are no more safe then anywhere else on the 'clear' Internet. The nature of networking and routing means your location is always known in server logs. It only takes one phone call to your ISP with your IP address to obtain both your physical ad...
When it comes to webcams these days, most people are using their laptops over desktops. The cameras are centered, integrated, and require no configuring. They're a cinch and usually have great resolution. So, then what do we do with all of those old wired desktop webcams that we've accrued over the years? Even if you still use an external USB one, chances are you're not using it daily, so why not come up with a better use for it?
