How To: Find Vulnerable Webcams Across the Globe Using Shodan

Search engines index websites on the web so you can find them more efficiently, and the same is true for internet-connected devices. Shodan indexes devices like webcams, printers, and even industrial controls into one easy-to-search database, giving hackers access to vulnerable devices online across the globe. And you can search its database via its website or command-line library.

How To: Hijack Chromecasts with CATT to Display Images, Messages, Videos, Sites & More

Giving up your Wi-Fi password can be giving up more control than you think. Because of the way Chromecast and other IoT devices communicate, anyone on the same Wi-Fi network as your device can often make it do whatever they want. With a script called "Cast All the Things," we can hijack a Chromecast to play nearly any kind of media with a single command in terminal.

News: Samsung Galaxy S10 Review, 3 Months Later: All the Little Things to Know

The Galaxy S10 has finally been revealed to the masses, and it certainly doesn't disappoint. As the flagship to herald the tenth anniversary of the venerable Galaxy S line, the S10 has kept popular and familiar design elements like the immersive Infinity Display while employing new features like more advanced cameras to set a new standard for other OEMs to follow.

How To: Use Ettercap to Intercept Passwords with ARP Spoofing

ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP-spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.

Hacking macOS: How to Steal Signal Conversations from a MacBook with a USB Rubber Ducky

Developed by Open Whisper Systems, Signal is a free, open-source encrypted communications app for both mobile and desktop devices that allows users to make voice calls, send instant messages, and even make video calls securely. However, a vulnerability was recently discovered for the desktop version that can be turned into a USB Rubber Ducky payload to steal signal messages with a single click.

How To: Hack SAML Single Sign-on with Burp Suite

Single sign-on (SSO) lets users login across different sites without having to manage multiple accounts. I'm sure most of us appreciate the convenience of seeing "Sign in with …" buttons that let us login with a single username. Hackers, however, see a possible avenue for exploitation, and you'll soon learn how an attacker can exploit a SAML vulnerability to assume another user's identity.

Venmo 101: The Fees, Limits & Fine Print You Need to Know About

Thanks to its intuitive interface that makes sending and receiving money a breeze, Venmo has become the go-to app for millions in the US. In fact, you've probably heard the term "Venmo you" being tossed around between friends. But before you take the plunge and sign up, it's always a good idea to read the fine print and know what you're getting into. Money is involved, after all.

How To: Gain Complete Control of Any Android Phone with the AhMyth RAT

There are more than 2 billion Android devices active each month, any of which can be hacked with the use of a remote administration tool, more commonly known as a RAT. AhMyth, one of these powerful tools, can help outsiders monitor a device's location, see SMS messages, take camera snapshots, and even record with the microphone without the user knowing.

How To: Exploit DDE in Microsoft Office & Defend Against DDE-Based Attacks

In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.

How To: Detect Bluetooth Low Energy Devices in Realtime with Blue Hydra

Bluetooth Low Energy (BLE) is the de facto wireless protocol choice by many wearables developers, and much of the emerging internet of things (IoT) market. Thanks to it's near ubiquity in modern smartphones, tablets, and computers, BLE represents a large and frequently insecure attack surface. This surface can now be mapped with the use of Blue Hydra.

Hack Like a Pro: Digital Forensics for the Aspiring Hacker, Part 7 (Windows Sysinternals)

Welcome back, my aspiring hackers! In many of my earlier tutorials, I mentioned the complementary nature of hacking and forensics. Both disciplines, hacking and forensics, benefit from a knowledge of the other. In many cases, both disciplines will use the same tool. In this tutorial, we will use another tool that can be used in either discipline—Sysinternals—a suite of tools developed by Mark Russinovich.

How To: Understanding Signature Schemes: How Data Sources Are Authenticated, Secured, & Spoofed

One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...

How To: Block Apps from Accessing Your iPhone's Camera to Prevent Privacy Invasions

The camera system on the iPhone has never been better. Apple's iPhone 11, 11 Pro, and 11 Pro Max sport some of the best shooters on the market. But no level of quality makes up for the fact that shady apps can access your cameras for nefarious reasons. You can take control of the situation, however, and block any app you want from using your rear and front-facing cameras.

How To: Prevent Others from Sharing Your Telegram Account Link When Forwarding Your Messages

Forwarding messages is a helpful Telegram feature that makes it easy to share funny and entertaining content with other contacts. However, for the privacy-centric, forwarding poses an issue, as messages of yours that are delivered elsewhere carry a tag back to your account. Luckily, you can make your messages anonymous, so anyone receiving messages of yours that are forwarded won't be able to see you originally sent the message.

How To: Temporarily Disable Your Instagram Account When You Need to Take an #InstaBreak

When you don't want certain friends viewing your account or just need to take a break from social media, Instagram lets you do so. While you can completely delete your Instagram account, then start over when you're ready again, it makes much more sense to just disable your account temporarily. Doing so will hide your profile, photos, comments, and likes from everyone, including your friends.
