Welcome back, my novice hackers! In a recent tutorial, I showed how the SNMP protocol can be a gold mine of information for reconnaissance on a potential target. If you haven't already, I strongly suggest that you read it before progressing here, as little of this will make m ...more

It's time. You've experimented with apps from the Play Store, you've switched your lock screen, and maybe you've taken different launchers out for a spin. If, throughout your tinkering, you've found yourself chanting, "More. More. Give me more!" then now is the time. It's time ...more

Take a minute and think about how many times a day you press the home key on your iPhone . . . a lot, right? It is quite literally the most important button on your device. If the home key stops working, you won't be able to multitask or back out of apps to go to your home scr ...more

There's no shortage of reasons to love the One, yet a feature curiously omitted from the device, much to the chagrin of power users, is a multitasking button. Most Android devices, in addition to 'home' and 'back' keys, have a 'multitasking' key which opens a task switcher an ...more

One of the lesser known features brought along by the roll-out of Android 4.4 KitKat is the ability to screen record from within the device. This features isn't overtly obvious, nor is its implementation the most streamlined, but if you were ever looking for a way to capture v ...more

I have literally played Madden, watched YouTube videos, and listened to music on my phone all at the same time. Some would call this pathetic, but I call it talent. Life is way too short, so I need to get the most out of it when I can. Thank goodness for multitasking, which sh ...more

The launch of Android 4.4 KitKat alongside the Nexus 5 was met with much fanfare from Android enthusiasts. Unfortunately, if you don't have a Nexus device or are still awaiting the 4.4 update, you may feel a bit left behind. If you have a carrier version of the HTC One, 2013' ...more

Let's get one thing straight: CyanogenMod is one hell of a ROM. They've got a great community, a great product, and getting it on your HTC One couldn't be easier with their CyanogenMod installer, which does all the hard rooting and bootloader unlocking for you. If at all you ...more

Welcome back, my budding hackers! One of the keys to becoming a professional and successful hacker is to think creatively. There is always a way to get into any network or system, if you think creatively. In previous tutorials, I have demonstrated ways to crack passwords on b ...more

The Nexus 5 is the current Google flagship packed with the latest and greatest of all things Android, but what if you never made the leap from your Nexus 4 smartphone? Though the N4 is a year old, it's no slouch, and it's still a Nexus. It was among one of the first devices t ...more

Overall, I love the Nexus 7 tablet, but one thing that I truly dislike about it is having to press the Power/Lock key to lock my screen. To begin with, it's on the right side of the device, and I'm accustomed to it being on the top on other devices, like my phone. Secondly, i ...more

Do you have an Alfa AWUS036NH Wi-Fi adapter that claims it can go to 2000 mWs, or some card that can supposedly transmit power over 1000 mW? If so, you may have run into problems setting your card's TXPOWER higher than 30 dBm, which is about 1000 mW. Well, I will show you how ...more

While the new Android 4.4 KitKat is only available on one device at the moment (damn you Nexus 5), it doesn't mean that we can't enjoy some of the features it has to offer on our non-KitKat devices right now. We can already get the KitKat launcher and Google Now on our Samsun ...more

Welcome back, my neophyte hackers! There are innumerable ways to hack a system. We must not overlook any of the possibilities if we want to "own" the system. As systems become more and more secure, we need to be vigilant in our search for weaknesses. In this hack, we'll look ...more

You probably already know what you want to do when you grab your phone. More than likely, you're either going to make a call, send a text, or open an app. So why can't you just do that right from your Samsung Galaxy S3's lock screen? Instead of entering in your passcode or pa ...more
