If you find yourself with a roommate hogging limited data bandwidth with video games or discover a neighbor has invited themselves into your Wi-Fi network, you can easily take back control of your internet access. Evil Limiter does this by letting you control the bit rate of any device on the same network as you, allowing you to slow or even stop data transfer speeds for them completely.
Most companies have services like employee login portals, internal-only subdomains, and test servers they would prefer to keep private. Red teams and white hat hackers can find these obscure and often vulnerable services using a tool designed to help protect users from fraudulent certificates.
Wi-Fi devices are continually emitting "probe frames," calling out for nearby Wi-Fi networks to connect to. Beyond being a privacy risk, probe frames can also be used to track or take over the data connection of nearby devices. We'll explain how to see nearby devices emitting probe frames using Probequest and what can be done with this information.
It's possible to stream a MacBook's entire computer screen without using Apple's Screen Sharing application and without opening any ports on the target device. A hacker with low user privileges on the backdoored Mac may be able to view a victim's every move in real time no matter where they are.

Ransomware is software that encrypts a victim's entire hard drive, blocking access to their files unless they pay a ransom to the attacker to get the decryption key. In this tutorial, you'll learn how easy it is to use the USB Rubber Ducky, which is disguised as an ordinary flash drive, to deploy ransomware on a victim's computer within seconds. With an attack that only takes a moment, you'll need to know how to defend yourself.
Cross-compilation allows you to develop for one platform (like Kali) and compile to run on a different platform (such as Windows). For developers, it means that they can work on their platform of choice and compile their code for their target platform. For hackers, it means we can compile exploit code for Windows from Kali.
Sharing your Wi-Fi password is like giving an unlimited pass to snoop around your network, allowing direct access even to LAN-connected devices like printers, routers, and security cameras. Most networks allow users to scan and attempt to log in to these connected devices. And if you haven't changed the default password on these devices, an attacker can simply try plugging them in.
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.

As our cells age, they eventually mature and die. As they die, they alert nearby cells to grow and multiply to replace them. Using a special imaging process that combines video and microscopy, scientists have observed the cellular communication between dying and neighboring cells for the first time, and think they may be able to use their new-found information against cancer cells, whose damaged genomes let them escape the normal dying process.
While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Raspberry Pi without using a screen or any other input.
Super Mario Run was released for iOS on December 15, 2016. Even though it debuted as a "free" app, almost all of the playable content was hidden behind a ridiculous $10 unlocking package. Despite coming with such a hefty price tag and receiving a two-star rating on the day of its release for iOS, Android users are still very much interested in giving this game a whirl.

The fact that it can and will be used against you in a court of law is just one reason to protect your phone, because even if you make sure to stay above the fray, identity theft and bank fraud are still very real threats.
Welcome back, my tenderfoot hackers! One key area on the minds of all hackers is how to evade security devices such as an intrusion detection system (IDS) or antivirus (AV) software. This is not an issue if you create your own zero-day exploit, or capture someone else's zero-day. However, if you are using someone else's exploit or payload, such as one from Metasploit or Exploit-DB, the security devices are likely to detect it and spoil all your fun.
Welcome back, my fledgling hackers! Over the years, we have examined multiple ways to own, exploit, or compromise a system. On the other hand, we have not spent a lot of time on denial-of-service (DoS) attacks.

Welcome back, my novice hackers! As we saw in my first tutorial on Facebook hacking, it is not a simple task. However, with the right skills and tools, as well as persistence and ingenuity, nothing is beyond our capabilities.
Welcome back, my tenderfoot hackers! Hacker newbies have an inordinate fixation on password cracking. They believe that cracking the password is the only way to gain access to the target account and its privileges. If what we really want is access to a system or other resources, sometimes we can get it without a password. Good examples of this are replay attacks and MitM attacks. Neither requires us to have passwords to have access to the user's resources.
