Debugging Hacking Tools To Use In 2020

Understanding how to fix glaring coding problems makes you a better hacker because you’ll understand where the vulnerabilities are.

If you’re a coder or programmer of any description using any coding language or library then you’ll certainly be aware of the importance of bug testing and fixing.

Debugging tools are a must for anyone serious software developer, programmer and of course, nefarious hacker.

We’ve listed a bunch of debugging tools (that we hope) you will find useful in your perennial quest to seek bugs in software, code, and programs.

It’s also worth mentioning for those that are interested in bug bounty programs that ‘de-bugging tools’ are definitely very useful when it comes to finding vulnerabilities that might exist on platforms, networks or others.

GDB: The GNU Project Debugger

GDB, or, the GNU Project debugger, is a cybersecurity pentesting/ hacker tool that allows the user to audit and discover what is being executed within a web app or program.

GDB is especially helpful for developers or programmers that are keen to understand why their application or program is crashing or whether their code has any vulnerabilities. GDB is a free hacking tool released under the GNU General Public License and was modeled after DBX Debugger which works on all Operating Systems including all Unix-like systems and works for many programming languages that includes C, C++, Ada, Free Pascal, Fortan, Java and many more.

What are the Typical Uses for GDB?

GDB has four major uses; these are: Seeing what happens when you start your program, detailing anything that might be affecting its’ behavior. Seeing what happens when you stop your program at specified actions or times of action. Investigate and try and understand why your program has stopped working the way it is meant to and alter things in your program to allow the developer to experiment with correcting the effects of a bug.


IDA PRO

IDA is a multi-platform (including Linux) multi-processor disassembler and debugger that programmers and developers can use to debug their applications. The ‘IDA Disassembler and Debugger’ have become a popular tool when evaluating code that is not working the way that it should be. Furthermore, IDA Pro allows the user to analyze possible vulnerabilities. According to the developer, the ‘IDA Disassembler works as close as is possible to the original source code’ hence why it is popular for those seeking a good debugger tool.

Is IDA Pro Free?

The latest full version of this tool is commercial but you can download a less capable and earlier version (version 5.0) for free.

Does IDA Pro Work on all Operating Systems?

This tool works on Windows, Linux and Mac OS X operating systems.

What are the Typical Uses for IDA Pro?

Two of the key features of this tool are Multitarget Disassembler and Multitarget Debugger.

Multitarget Disassembler is a Disassembler module for a huge number of processors. It has full extendability and interactivity and closes as possible to high-level source code. While Multitargert Debugger is a debugger that adds dynamic analysis to the data gathered by the disassembler. It also offers complete features expected from a debugger.


Immunity Debugger

The Immunity CANVAS pentesting tool can be used to test how vulnerable your system really is. This hacking tool ships with purposely designed vulnerability exploitation modules. The modules that have been written to discover exploits. Immunity CANVAS provides a solution for any organization to have a concrete picture of their security profile.

WinDbg, like OllyDbg, is a multipurpose debugger for Microsoft Windows that is distributed by Microsoft. This hacker tool can be used to debug mode applications and drivers. The tool can also be used to find bugs within the operating system itself, i.e. within the kernel mode. WinDbg runs from a GUI application. Many users of this tool also tend to use the Visual Studio Debugger. WinDbg can be used for debugging kernel-mode memory dumps.

For those that don’t know, ‘kernel-mode memory dumps’ is the data that is accumulated from the ‘Blue Screen Of Death’. WinDbg can also be used for post-mortem debugging. WinDbg also has the ability to automatically load debugging symbol files (for example PDB files) from a server by matching various criteria (e.g., timestamp, CRC, single or even the multiprocessor version).

Is WinDbg Free?

All official versions are free.

Does WinDbg Work on all Operating Systems?

No, It only works on Windows operating systems.

What are the Typical Uses for WinDbg?

The primary purpose of this tool is to debug memory dumps after Windows operating system encounters a crash or what others call the “Blue Screen of Death”. This tool can also let you debug in Kernel mode.


Popular Debugging FAQ

What Does “Debugging” Mean?

Debugging is the process that software programmers will execute to be able to detect and remove existing and potential errors (which are referred to as ‘bugs’) in software code. They do this to prevent unexpected crashes and future problems. The main reason why we perform debugging checks is to prevent the incorrect operation of a software or system and exercising this operation will find and resolve bugs or defects.

What Are Instruction-set Simulators?

A debugger is a computer tool (which can also be used by hackers to test and debug software. Debuggers may use instruction-set simulators as opposed to running a program directly on the processor to achieve a higher level of control over its operational execution.

Why Is Debugging Called That Way?

Credit for the terms “bug” and “debugging” are widely attributed to Admiral Grace Hopper in the mid-1940s. Whilst was working on a Mark II computer at Harvard University, her associates found that a moth has lodged itself in a relay and had short-circuited the system. Commenting on this she wrote in her diary: “First actual case of bug being found” and the term “debugging” came into existence.

How Important Is It To Debug?

Debugging is a vital step in being able to test and find errors or “bugs” in a program or application so that the problem (or “bugs”) can be fixed thereby making the program function in the way it was desired.

Typically this is done pre-commercial launch.

What Is Meant By Post Mortem Debugging?

The “Post Mortem Debugging Process” is a process in which, with the use of several tools (many listed in this resource) you’d examine a memory dump when an issue occurs and later analyze it offline. The intention being of discovering errors within the code and logs.

What Is The Debugging Process?

The software engineer would typically examine process ID’s and execute a bunch of commands through logic. Debugging tools then read and write on the targets’ virtual memory, and try to “fuzz it” by for example adjusting its register values through APIs provided by the OS.

Why Bother Debugging?

Debugging is the routine process of locating and removing computer program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications.

What Is USB Debugging And Is It Safe?

USB Debugging allows an Android device to communicate in tandem with another computer running the Android SDK to use advanced operations such as bug-fixing. It’s a useful mobile tool.

Is It Possible To Turn Off “USB Debugging”?

You can turn off USB debugging on your Android by going to Settings, Developer Options, and then turn off USB debugging. After you turn off USB debugging you may want to reboot your mobile or Android device.

Encryption Tools & Software

Encryption Communication Tools To Use In 2020

Once upon a time, there was the Caesar Cipher.

And, even before then, there were encryption v.0.0.0.1 which was to shave the hair off a slave, write the ‘encrypted’ message, let the hair grow back and then the slave (messenger) would physically go and report to the recipient of the message.

Before the Diffie-Helman key exchange security agencies (GCHQ, NSA and 5 Eyes) were able, for the most part, to read secret messages. Codes could be broken prior to Diffie-Hellman and later RSA (Rivest, Adelman, and Shamir) pioneering work.

Before we go on any further, with respect to the history of encryption we should offer a brief mention to the genius that was James Ellis who is credited for being the real first person to create the two-key encryption method but who has largely been forgotten about.

Without digressing further, what we’ve done on this resource is to list a bunch of encryption tools and links to encryption software that we hope you will find useful.

Recommended Encryption Tools

In summary, Tor is essentially a network of virtual tunnels that allows users to communicate privately online.

Remember when using Tor that the exit nodes of Tor are sometimes run by malicious parties that can sniff your traffic so evade authenticating using an insecure network protocol.

Is Tor Free?

Yes, Tor is free.

How does Tor Work?

Tor makes the user anonymous because it relays data from one node to another. “Tor” is an abbreviation for “The Onion Router” (hence the logo) so imagine that multiple nodes are like the layers of an onion that are bounced around the world.

Does Tor Work on all Operating Systems?

Tor natively works on Linux, MAC OS X, and Microsoft Windows.

What are the Typical Uses for Tor?

End-users use Tor to keep websites (and in most uses, the authorities) from tracking their search queries, browsing history and messaging. One of Tor’s most popular uses is to hide the real IP address (location) of the user. Here are two excellent uses of Tor: firstly, rape and abuse victims can use private and secure chat rooms and web forums, and secondly, journalists can communicate more safely with one another.


Stunnel

This tool is designed to work as an SSL encryption wrapper between remote servers and remote clients. Stunnel can benefit from FIPS 140-2 validation of OpenSSL FIPS Object Modules.

FAQ

Is It Safe And Legal To Volunteer As A Tor Exit Node?

Legal? Basically yes (in the United States) but a good idea? Definitely not.

Your ISP will be able to read all your exit traffic and my gosh, there will likely be a lot of nefarious and sinister stuff that you will be (could be) liable for.

How Safe Is It To Use Tor?

The answer is, basically, yes – it is safe.

However, there are certain measures that you need to take, for example, it is highly recommended that you don’t use Javascript and always make sure that you are using the correct Tor software.

The most notable episode in which Cybersecurity Professionals considered Tor “might” be unsafe is when Gizmodo reported in December 2014 that a group of hackers had been able to get acquire enough Tor Relays to decloak the actual users within the Tor network (through the relays they “controlled”). Whilst that might have been the case the hackers did not have control of enough relays which were subsequently scrambled to have caused any real damage.

An example of someone being caught using Tor is Eldo Kim.

Is It Possible To Encrypt SMS, Text Messages?

Yes, you will need to open your device and install the Secret Message app. You then need to enter a secret key into the “Secret Key Box” at the top of the android app’s screen. To use you then simply type the message you want to encrypt into the Message box, hit “Encrypt” and tap “Send via SMS” to send the encrypted message to the receiver.

Is It Possible To Encrypt Gmail In 2020?

Right-click anywhere in the email body and select the “Encrypt Communication” option. Enter the desired password with which to encrypt your Gmail and click “OK.” Open the message in the recipient’s inbox. Right-click anywhere in the email body and select “Decrypt Communication.”

Is Google Drive Completely Encrypted?

The Google Drive that works on the Google Cloud and as such it can loosely be considered as being secure. However, Google Drive’s server-side encryption is not as tough as other platforms out there so if you feel that you have highly sensitive data then we’d perhaps suggest another solution.

Is It Possible To Recover Encrypted Data?

It depends. Almost impossible to answer just like that!

How Is Data Encrypted?

Data encryption converts data into another form, or code so that only users with access to a secret key (formally called a decryption key) or password can read it. There are 2 types of data. First is Encrypted data which is commonly referred to as ciphertext. Second, the unencrypted data is known as plaintext.

How Do I Encrypt A Computer?

There are a lot of ways to do that. The easiest way is to use an operating system called Linux. There is plenty of Distro’s that ship with the ability to secure and encrypt the hard drive when the system is first initialized and installed. My favorite for this is POP_OS.

How Secure Is Encrypted Email?

I can be very secure. If the processes have been configured accurately then encrypted email is protected. Authentication is also included in Email Encryption. Most emails from the sender are sent using plaintext and are transmitted in the clear (i.e. not encrypted) form. Emails that are sent using a Gmail or Outlook are encrypted by default.

Is It Possible To Forward Email That’s Been Encrypted?

Typically the answer is said to be “no”.

It varies on the email client and your setup. Often times forwarding a ciphertext email will mean that the recipient will not be able to read the email unless they have their own key.

How Do I Open Encrypted Gmail?

Yes probably. Simply open the encrypted Gmail email, get the body of the email and copy it to your clipboard, use the secret key that the sender shared with you and past the string. Tap the “Decrypt” button and you’ll be able to read the contents.

Can I Encrypt My Emails Using Gmail?

Yes, you can encrypt your emails using Gmail but it does come with certain limits. To make your emails more secure you would need to add an additional layer of client-side encryption, via third-party chrome extensions and add-ons.

The default Gmail encryption client does protect your emails as much as it can, and indeed Google’s servers encrypt emails both when they’re stored (data at rest) and when they’re being sent (data in motion). If you are seeking an even more secure email encryption solution we’d recommend Protonmail.

Is Gmail “Confidential Mode” 100% Encrypted?

All Gmail communication is end-to-end encrypted and zero-access encrypted. “Zero Access” means that not even the admin can read the emails. Gmail has a bunch of add-ons and extra features like for example the ability to set expiring dates on emails, which are destroyed after a period of time chosen by the sender. The decision, of course, is yours as to whether you 100% trust and believe Google’s Privacy Policies.

Is Gmail Encryption Always On?

Previously, Gmail began as optional. Now, it is always on. Not only are Gmail messages encrypted between recipients they are also encrypted as they travel around Google’s global data centers.

Are Mobile Apps Safe To Send Encrypted Messages On?

The answer is that it depends. We actually have a resource on that here.

What Is Onion Routing?

“Onion Routing” made most famous by Tor, is a process best described as being opposite to “peer-to-peer”. If you jump on PirateBay, BitTorrent or any of those other old-school peer-to-peer (bit-torrent) sites then you’re IP is exposed to everyone within the share. “Onion Routing” technology uses a series of intermediary nodes that in transit encrypt the data as it travels through the network.

The exit node also decrypts your traffic and the route that it took.

Die to this anonymizing process you, as a user, are “anonymous” owing to the fact that your data has been transmitted through “onion layers” that hide your true and real IP address.

Firewall Software & Tools

Content Written By Henry Dalziel, 2020

Firewall Tools You Can Use

This is the most skinny of all resources I have on this site, but the two tools I have listed I believe will be still best suited for 2020, although admittedly I haven’t used them in a few years now.

Firewalls as a technical term, when applied to Cybersecurity, is possibly one of the greatest ever ‘marketing coups’ with regards to its’ perception. The term ‘Firewall’ conjures up an instant image of protection and security but alas nothing could be further from the truth.

Firewalls are only as good as the human being behind it. The IT Team (perhaps ‘Security Team’) that manages the Firewall(s) will need to set-up rules for ingress and egress traffic as well as ensuring that the ruleset is all configuring correctly.

The patching of Firewalls is also of vital importance so just simply stating that you “have a Firewall so I’m ok!” is a misnomer.

In this resource, we list a bunch of Firewall solutions that we’d recommend. There are many (read: hundreds) of different Firewall solutions, vendors and strategies so tread carefully with this list.

The pricing of Firewalls and indeed all affiliated software connected therein (such as SOC Software) for example varies tremendously from it being Open Source to it being extremely expensive.

OpenBSD PF
Netfilter

OpenBSD PF

Packet Filter is this hacking tool’s method for filtering TCP/ IP traffic and running Network Address Translation. PF is also capable of normalizing and conditioning TCP/IP traffic.

This tool also provides bandwidth control and packet prioritization. Packet Filtering has been a part of the “GENERIC OpenBSD kernel” since OpenBSD 3.0. Previous kernel versions of OpenBSD shipped with a different firewall/ NAT that is no longer supported.

Is OpenBSD PF Free?

Yes, this product is absolutely free.

Does OpenBSD PF Work on all Operating Systems?

Just like Netfilter, OpenBSD only works for Linux operating systems.

What are the Typical Uses for OpenBSD PF?

A lot of users love OpenBSD due to the fact that it handles networks address translation, gives you a bandwidth control, packet prioritization and can normalize TCP/IP traffic. Users of this tool will have access to features such as passive OS detection.


Netfilter

Netfilter is a classic Firewall hacking tool used by many within the cybersecurity industry. The tool (framework) essentially filters packets inside Linux 2.4.x and later kernels.

Netfilter is a series of hooks inside the Linux kernel that allows kernel modules to perform callback functions within the network stack. A registered callback function is then called back for every packet that traverses the respective hook within the network stack. iptables is a generic table structure for the definition of rulesets.

Each rule within an IP table consists of a number of classifiers (iptables matches) and one connected action (iptables target). netfilter, ip_tables, connection tracking (ip_conntrack, nf_conntrack) and the NAT subsystem together build the major parts of the framework.

Is Netfilter Free?

Yes!

Does Netfilter Work on all Operating Systems?

It’s only for Linux operating systems.

What are the Typical Uses for Netfilter?

Netfilter allows the user to filter packets, network addresses along with ports, translations (within the NA[P]T protocols) and another packet auditing.


FAQ

What Are The 3 Main Types Of Firewall?

The three basic types of firewalls that help companies to protect their data & devices and keep destructive elements out of their networks are Packet Filtering, Stateful Inspecting, and Proxy Server Firewalls.

What Is A Network Firewall?

A firewall is a system that serves as prevention against unauthorized access to or from a private network. A firewall can be executed either hardware or software form or a combination of both. It avoids and blocks unauthorized internet users from accessing private networks connected to the internet, especially intranets.

Why Are Firewalls Called “Firewalls?”

A firewall is basically referred to as a wall intended to confine a fire or potential fire within a building. Later uses refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment.

What Is Meant By Proxy Firewall?

A proxy firewall is a network security system that secures a network resources by filtering messages at the application layer. It is also called as an application firewall or gateway firewall.

What Is Meant By A Layer 3 Firewall?

Typically, firewalls are used to secure internal/private LAN from the Internet. It works at layer 3 and 4 of the OSI model. Layer 3 is the Network Layer where IP works and Layer 4 is the Transport Layer, where TCP and UDP function

How Does A Firewall Work?

Hardware firewalls work by examining the data that is found in the Internet and checking whether that information is safe. Simple firewalls, known as packet filters, examine the data itself for information such as its location and its source.

What Is A Hybrid Firewall?

Hybrid Firewall effectively protects your servers and workstations from malicious probes and unauthorized access. Packet Filtering Firewall. Blocks or allows packets through the network depending on the source/destination IP, protocols and ports.

How Do You Define A Firewall Attack?

A firewall can defeat an attack if it discards all the packets that arrive at the incoming side of the firewall; as long as the source IP is equal to one of the internal IPs. Source Routing Attacks are different since the attacker specifies the route to be taken by the packet with a hope to fool the firewall.

Can You Consider A Firewall As A Device?

A firewall can be classified either as hardware or software. A hardware firewall is a unit that is linked between the network and the device for connecting to the Internet. A software firewall is a program that is installed on the computer with the presence of the Internet connection.

How Much Is It Cost To Install A Firewall?

Host-based firewalls usually cost around $100 or less. Enterprise firewalls can cost over $25,000. The most popular medium-range business firewalls cost from $1500 to around $5000; so, in other words, yes – the price totally varies.

Does Mcafee Function As A Firewall?

McAfee firewall creates a wall between your computer and the internet. Further, the McAfee firewall provides complete inbound and outbound firewall protection. It trusts known good programs and helps block spyware, trojans, and key loggers

Digital Forensic Tools & Software

Digital Forensic Hacking Tools For Use In 2020

Cybercrime keeps growing. My research shows that Pre-COVID, i.e. BCV, (Before Corona Virus) the estimates were that Cybercrime will cost as much as $6 trillion annually by 2021. However, owing to the “desperation” many unemployed now feel, this figure might be a lot higher.

Digital Cybersecurity Forensics is a booming niche that will likely remain so for a long time.

Digital Forensics is a massive subject and requires meticulous planning and execution for it to be deemed successful. When we say ‘successful’ we refer to there being a guilty conviction for am incriminating cybercrime that took place.

Typically InfoSec Digital Forensics is dictated by the “Chain Of Custody” principle and vital to that process is the procuring and storing of evidence which is achieved by some of the tools that we’ve gone ahead and listed below.

Within all the different IT security careers we’d say that Digital Forensics ought to be one of the fastest-growing sectors within Cybersecurity. The sheer escalating level and variations of hacks all require investigation, analysis, and legal processes to secure convictions.

Maltego

Very possibly one of the best-known forensics and social engineering hacking tools on the market. It’s a very popular tool amongst those that are familiar with it.

Maltego is developed by Paterva and is a tool used for open-source forensics and intelligence. Its focus is to provide a library of transforms for the discovery of data from different open sources and visualize that data into a graph format which is suitable for data mining and link analysis.

Maltego allows building custom entities, allowing it to produce any type of information in addition to the types of basic entity which are part of the tool. The primary focus of this tool is to analyze real-world relationships between people, websites, groups, internet infrastructure, networks, domains and affiliations with social media services such as Facebook and Twitter.

This hacking tool has two types of reconnaissance options, personal and infrastructural. Personal reconnaissance includes personal information such as phone numbers, email addresses, mutual friends, social networking profiles, etc. while Infrastructural reconnaissance deals with the domains, covering DNS information such as mail exchangers, name servers, DNS to IP mapping and zone transfer tables.

Maltego sends clients’ information in the XML format over a secure HTTPS connection by using seed servers. Once the information is processed at the server-side, the results are brought back to the Maltego client. Getting all publicly available data using manual techniques and search engines is time-consuming but with Maltego, it automates the data gathering process to a great extent, thus saving a lot of time for the user/attacker.

Is Maltego Free?

Maltego CE and Casefile are free to download wherein Maltego XL and Maltego Classic are paid tools. Maltego XL is the premiere edition of this tool. Features and capabilities of Maltego Classic are included here but this is the enhanced version that can work on large graphs. This will also allow you to map out a clear threat picture of the entire network making it easy in identifying abnormalities or weak points.

Maltego Classic, on the other hand, is the professional version of Maltego that gives extended compatibilities and functionalities with the community version of the tool. This can also be used in a commercial environment in which free versions cannot. This paid tool can create far larger graphs compared to the community version since this has no limitation on the entities that can be returned from a single transform. You can also export the results from a range of different formats.

Does Maltego Work on all Operating Systems?

Maltego currently works on Windows, Linux and Mac operating systems.

Packet Sniffers & Crafting Tools

Content Written By Henry Dalziel, 2020

Here Are Some Of The Best Packet Sniffing Tools For 2020

Yes indeed, the brunt of many a joke. The first time I spoke about Packet Sniffing to my business partner he thought I was being a pervert…

No, alas, packet sniffing is all about being able to detect and in many cases manipulate the packets that are flowing in and out of a network.

The tools and software that we are listing on this page we hope will be of use to you in your quest to improve your Cybersecurity skills!

The tools that we list here vary with usage but what we’ve done is tried to list as many genuinely useful packer sniffer tools that we have used in the past.

It’s all about the packets stupid!

The HTTP protocol and heck, the entire Internet, is dependent and committed to using the TCP/ IP and UDP protocols (as well as a bunch of other variations).

Anyone reading this page should be aware of the importance of understanding how protocols work if you are to try to break the flow or attempt to ‘corrupt’ the transmission of ‘packets’.

To those that are completely unfamiliar with packet behavior then we strongly suggest that you learn about it.

Being able to spoof and ‘trick’ packets is a major weakness in network security and if you can master how to use the tools that we’ve listed below then you are in a great spot.

We’ve tried to list the ‘best packet crafting tools’ that we can find (and have used) but like most things, in IT the landscape is constantly evolving.

Wireshark

Wireshark is an absolute classic and probably the best-known network analyzer and password cracking tool. Of course, the password must be sent via an encrypted format for Wireshark.

This tool is a network packet analyzer and this kind of tool will try to capture network packets used for analysis, network troubleshooting, education, software, and communications protocol development and display the packet data obtained as detailed as possible.

Formerly named Ethereal, it was renamed to Wireshark in May of 2006 due to trademark issues. Wireshark is a cross-platform that now uses the Qt widget in current releases to implement its user interface. If you know tcpdump, Wireshark is very similar to it but has a graphical front-end and some integrated filtering and sorting options.

Wireshark supports promiscuous mode that lets the user put network interface controllers into that mode, for them to see all traffic visible on that interface, not only the traffic directed to one of the interface’s configured addresses and broadcast/multicast traffic. But, when in promiscuous mode capturing with a packet analyzer on a port on a network switch, not all traffic through the switch is sent to the port where the capture is made, so capturing in this mode is not necessarily enough to see all network traffic.

Various network taps such as Port Mirroring extend capture to any point on the network. Simple passive taps are greatly resistant to tampering. Wireshark 1.4 and later on GNU/Linux, BSD, and OS X, with libpcap 1.0.0 or later can also put wireless network interface controllers into monitor mode.

When a remote computer machine captures packets and transmits the captured packets to a machine running Wireshark using the protocol used by OmniPeek or the TZSP protocol, those packets are dissected by Wireshark, so it can analyze packets captured on a remote machine at the time that they are captured.

In Wireshark, there are color codes and the users see packets highlighted in black, blue and green. It helps users in identifying the types of traffic at one glance. Black color determines TCP packets with problems. Blue colors are the DNS traffic while Green is the TCP traffic.

Is Wireshark Free?

Wireshark is an open-source and free packet analyzer. You can go to its website (https://www.wireshark.org/download.htmlZ) and download the installer that is compatible with your system.

Does Wireshark Work on all Operating Systems?

FAQ

How Do I Use A Packet Sniffing Tool?

A packet sniffer, also referred to as a packet, protocol or network analyzer — is typically a piece of hardware or software used to detect and monitor network traffic. Sniffer tools work by examining streams of data packets that flow within the veins of a network, i.e. between computers on a network as well as between networked computers. This typically exists within an Intranet environment.

What Is The Definition Of Packet Sniffing?

When we refer to “packet sniffing” what we mean is the ability in using “packet sniffing tools” to capture packets of data that are moving through a computer network. The software tools that do this task are referred to as “packet sniffers”.

How Do I Execute A Packet Sniffing Tool?

In packet-switched networks, the data is sent and received by being broken into several individual packets. These individual packets are reassembled after all the data packets reach their final destination. When a packet sniffer is installed in the network, the sniffing tool will be able to intercept the network traffic and captures the raw data packets. A good example of a sniffing tool that can do this is Wireshark.

Is Packet Sniffing Authorized By Law?

You’re absolutely allowed to monitor your computers and network but you cannot install packet-sniffing tools and software a network without explicit permission for obvious reasons. Doing so would, without doubt, label your actions as a rogue operator and “hacker”.

Can I Block Packet Sniffing Through VPN?

An effective method of being able to protect data from packet sniffing tools is to (encrypt) or “tunnel” your connectivity through a virtual private network, or a VPN. A VPN encrypts the traffic being sent between your computer and the destination. A packet sniffing tool would still see the data but it would be seen as ciphertext. i.e. encrypted.

What OIS Layer Does Packet Sniffing Work On?

Packet sniffing tools work at the data link layer of the OSI model, i.e. where MAC addresses work; which is “Layer 2”. IP addresses and packets are layer 3, whilst MAC addresses are Layer 2. Your installation of Wireshark would, therefore, be at Layer 2 (for example should you decide to use that specific packet sniffing tool).

Is Wireshark “The Best” Software For Packet Sniffing?

Wireshark is by far the most popular (free) open-source packet analyzer. The tool is used for network troubleshooting, data analysis, packet analyzing software and communications protocol development. The folks behind this popular tool also deploy a bunch of useful certifications.

How Do Packet Sniffing Tools Work?

Packet sniffing tools works by intercepting and logging HTTP/HTTPS traffic that passes over a digital network or part of a network. These tools essentially act as a MITM (Man In The Middle) piece of software. Typically these tools can be tweaked to your specifications.

How Should We Define “Packet Capture?”

Packet Capture is a networking term for being able to intercept data packet information that is in transit. Once a data packet is captured in real-time, it is stored for a period of time so that it can be further analyzed, and then an action can be taken.

How Would You Define Packet Modification?

Packet Editing or Packet Modification is the art (and science of course!) of being able to modify data packets that are either in transit or initiated in transit There are a bunch of tools that can be used for data modification (‘packet crafting’) such as Scapy, Netdude, and Ostinato all of which allow the “hacker” or Security Professional to modify packets.
