How To: Abuse Vulnerable Sudo Versions to Get Root

Anyone who has used Linux long enough is familiar with sudo. Short for superuser do (or substitute user do, depending on who you ask), it allows users to run commands as either root or another user on the system. From a hacker's point of view, sudo is often all that stands between them and root access. We'll be exploring an older vulnerability in sudo that allows a user to run commands as root.

How To: Get Root Filesystem Access via Samba Symlink Traversal

Samba can be configured to allow any user with write access the ability to create a link to the root filesystem. Once an attacker has this level of access, it's only a matter of time before the system gets owned. Although this configuration isn't that common in the wild, it does happen, and Metasploit has a module to easily exploit this security flaw.

How To: Perform Directory Traversal & Extract Sensitive Information

With all the web applications out on the internet today, and especially the ones built and configured by novices, it's easy to find vulnerabilities. Some are more perilous than others, but the consequences of even the slightest breach can be tremendous in the hands of a skilled hacker. Directory traversal is a relatively simple attack but can be used to expose sensitive information on a server.

How To: Find Missing Apps on Your iPhone

Unlike on Android, you can't easily hide your iPhone apps. Sure, you can nestle them away in folders labeled "junk," but they're supposed to be omni-present somewhere on your home screen. That is, until one day they're just ... gone. The fact that some of your apps disappeared only makes it more frustrating because there's no logical reason why they should have, right?

How To: Upload a Shell to a Web Server and Get Root (RFI): Part 2

If you remember last time, we successfully uploaded picture with a small hidden PHP command executer embedded in it onto a server. Now, our goal is to take this a step further and get an interactive shell. To do this, we need to upload another file that either binds a port for us, or connects back. For this tutorial, we will use a Python reverse Meterpreter shell.

How To: Root Your LG G3 (Any Carrier Variant)

The world of root is upon us, folks. While the LG G3 has be available for purchase for a couple of months now, rooting had been a shaky subject. International and T-Mobile variants enjoyed root from day one, while various security patches left the AT&T and Verizon Wireless variants as a mixed bag, and Sprint completely out in the cold.

How To: There's an Easy Way to Stop Random Popup Ads on Android

"Why do I keep getting popups on my phone when I'm not even doing anything?" I see this question asked all the time. The answer? You have a shady app on your phone and it started showing full screen ads. But people either don't know this (so they don't know they just need to find and uninstall the problematic app), or if they do know it's a bad app, they don't know which app is causing it.

News: Apple's iOS 12.4.1 for iPhone Fixes Jailbreak Vulnerability, 12.4.2 Patches Other Security Issue

While all eyes might be on the next beta release for iOS 13, Apple is still pumping out updates for iOS 12. The company released iOS 12.4.1, the first update since iOS 12.4, on Aug. 26. The latest update includes a patch for the jailbreak vulnerability recently discovered in 12.4. One month later, on Sept. 26, iOS 12.4.2 came out for older iPhone models.

How To: Lock Magisk Superuser Requests with Your Fingerprint

It's been proven that hackers can manipulate your screen with fake taps through specific exploits, so they can potentially hit the "Grant" button when you get a superuser request. This is the last thing you'd want to happen since the malicious app from that point forward has full system privileges. Luckily, using a fingerprint to lock your superuser requests can prevent this.

How To: The Best Way to Record Calls on Your OnePlus 3 or 3T

The beta firmware for OnePlus devices lets you record calls from the stock Oxygen OS dialer, but this feature is never included in official updates. This is likely due to legal issues with recording calls in some jurisdictions, but thankfully, there's a way to get this feature without having to run beta software.

How to Meterpreter: Obtaining User Credentials with PowerShell

In this article I will show you how to obtain victim's credentials without cracking any hashes. There are a couple of ways to perform this task (for example dumping the SAM file and cracking the NTLM hashes), but here I will explain how to do it using PowerShell and a bit of social engineering. We are going to create a fake login popup.

How To: Add a Password, Pattern, or PIN Lock to Any App on Your HTC One or Other Android Device

Keeping prying eyes off your device isn't always the easiest thing to do, especially once you lend somebody your phone to make a call. Seems that whenever someone is scrolling through your pictures or checking out your new phone, they always end up somewhere you don't want them be. You could always hover over their shoulder to make sure they're not getting into your texts or photos, but that isn't always possible.
