As we've seen with other tools and utilities, administrators typically use certain things to do their job more efficiently, and those things are often abused by attackers for exploitation. After all, hacking is just the process of getting a computer to do things in unexpected ways. Today, we will be covering various methods to perform banner grabbing to learn more about the target system.
Privilege escalation is the technique used to exploit certain flaws to obtain elevated permissions relative to the current user. There are a vast number of methods out there to go from user to root on Linux, and keeping track of them all can be difficult. This is where automation comes into play, and a privilege escalation script called Linux Smart Enumeration is one to take advantage of.
The art of fuzzing is a vital skill for any penetration tester or hacker to possess. The faster you fuzz, and the more efficiently you are at doing it, the closer you come to achieving your goal, whether that means finding a valid bug or discovering an initial attack vector. A tool called ffuf comes in handy to help speed things along and fuzz for parameters, directors, and more.
Everybody knows not to store sensitive information in unencrypted files, right? PDFs and ZIP files can often contain a treasure trove of information, such as network diagrams, IP addresses, and login credentials. Sometimes, even certain files that are encrypted aren't safe from attackers. That's where Zydra comes in — a tool for cracking RAR files, ZIP files, PDF files, and Linux shadow files.
Network enumeration is one of the essential phases of an attack, but it can take a lot of time and effort depending on the size. We've all been spoiled by Nmap and similar tools, and while there is a learning curve involved, they are extremely useful. But there's also GoScan, a tool that builds upon Nmap, offering an automated way to enumerate networks and services quickly.
The internet has undoubtedly changed the way we work and communicate. With technological advances, more and more people can collaborate on the web from anywhere in the world. But this remote-friendly environment inherently brings security risks, and hackers are always finding ways to exploit systems for other uses.
Hackers often find fascinating files in the most ordinary of places, one of those being FTP servers. Sometimes, luck will prevail, and anonymous logins will be enabled, meaning anyone can just log in. But more often than not, a valid username and password will be required. But there are several methods to brute-force FTP credentials and gain server access.
SSH is one of the most common protocols in use in modern IT infrastructures, and because of this, it can be a valuable attack vector for hackers. One of the most reliable ways to gain SSH access to servers is by brute-forcing credentials. There are a few methods of performing an SSH brute-force attack that will ultimately lead to the discovery of valid login credentials.
