If you buy an Android phone from any of the big US carriers, it will come with several extra apps in addition to any apps the manufacturer preinstalled. It's all in the name of profit, of course. Some of these apps are from companies that paid the carriers to distribute their ...more

There are three tiers to Android customization: things you can do by default, things you can do with ADB, and things you can do with root. While root is still pretty tricky to get, ADB mods just got a lot easier. Back in Android 9, Google added a feature that allowed you to w ...more

The price of hacking Wi-Fi has fallen dramatically, and low-cost microcontrollers are increasingly being turned into cheap yet powerful hacking tools. One of the most popular is the ESP8266, an Arduino-programmable chip on which the Wi-Fi Deauther project is based. On this ine ...more

Have you ever used an open wifi, which after you connect displays a website to enter your credentials to get internet? That website is called captive portal and widely used in airports, hotels, universities etc. Have you ever wondered what would happen if someone would set up ...more

With an ordinary birthday card, we can introduce a physical device which contains malicious files into someone's home and deceive them into inserting the device into a computer. In my last series, we used a Post-it note to trick a neighbor into visiting a website that we cont ...more

Most users don't realize how much valuable data is in their network traffic. With a few simple tools, an attacker can quickly pick out cookies, passwords, and DNS queries from a macOS device as it covertly streams the victim's network traffic to the attacker's system. Here, we ...more

The misconception that macOS is more secure than the Windows operating system is far from the truth. With just one small command, a hacker can completely take over a MacBook and control it remotely. The sheer volume of Windows computers currently in operation around the world ...more

Apple's Gatekeeper security software for macOS (Mac OS X) is vulnerable to remote attacks up to version 10.14.5. An attacker that's anywhere in the world can exploit MacBooks and other Mac computers by sharing a single ZIP file. The vulnerability was discovered by Filippo Cav ...more

Now that we have our payload hosted on our VPS, as well as Metasploit installed, we can begin developing the webpage which will trick our "John Smith" target into opening our malicious file. Once he has, we can take over his computer. This part is more involved, but the first ...more

Open-source data scraping is an essential reconnaissance tool for government agencies and hackers alike, with big data turning our digital fingerprints into giant neon signs. The problem is no longer whether the right data exists, it's filtering it down to the exact answer you ...more

Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing u ...more

In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encrypti ...more
