For any red teamer, SSH bastions (hosts that can control access between environments) can be difficult to compromise due to the use of multi-factor authentication (MFA) technologies. In a typical scenario, you may end up on a user’s host that has access to the bastion thanks to phishing or exploiting a vulnerability with the compromised user’s permissions. Learn more about SSH multiplexing and its role in bypassing authentication on SSH bastion hosts:

Wondering how to speed up a debugger? Here are some tips to consider while building one for Python:
In my previous article, I explained how to make Python modular by using functions, creating modules, or both. Functions are invaluable to avoid repeating code you intend to use several times, and modules ensure that you can use your code across different projects. But there's another component to modularity: the class.
If you're using Python for any amount of development, you have probably issued a command in a terminal, even if only to launch a Python script or install a Python module with pip.
Nowadays, Wi-Fi is a “need” for almost everyone. Whether you are visiting a mall or dining in a restaurant, waiting at the airport or spending time at the library, you can easily access the internet through public Wi-Fi networks from any location free of cost.

Python is one of the most popular programming languages in use today—and for good reasons: it's open source, it has a wide range of uses (such as web programming, business applications, games, scientific programming, and much more), and it has a vibrant and dedicated community supporting it. This community is the reason we have such a large, diverse range of software packages available in the Python Package Index (PyPI) to extend and improve Python and solve the inevitable glitches that crop up.
People tend to play fast and loose with security terminology. However, it's important to get your malware classifications straight because knowing how various types of malware spread is vital to containing and removing them.

While companies are quick to integrate new technologies to stay ahead of their competitors, every new technology also comes with risks. Malware, phishing and other cyberattacks are an all-too-common occurrence — especially following the implementation of newer technologies.
I've always been interested in web development and software architecture because I like to see the broader picture of a working system. Whether you are building a mobile app or a web application, it has to be connected to the internet to exchange data among different modules, which means you need a web service.
