🔰 HACKER FUNDAMENTALS
A Tale of Two Standards 🔰

OSI, TCP and What's Going on Here?

A good way to understand what a protocol is, would be to view it like a language. If people were network interfaces and all spoke their own language, there would be no way for them to properly communicate. A protocol works the same way, by agreeing to use certain methods or standards, many groups can build and create things that can all communicate with each other. So when you see TCP/IP protocol, think of it like a collection of rules computers must all follow to allow the millions and millions of networked machines called the Internet to function.
OSI was never meant to be just a model. Back in the 1970s, it was a competing protocol against TCP/IP and was actually a better protocol in design. The main reason it didn't take hold was that its addresses were hexadecimal and very complex. In fact, it was thought back then, that it had too many available addresses. Being based in hex, it allowed far more than the current protocol standard of IPv4. I should point out that the next version of IP, version 6, uses hex addresses which allow many more available ranges then IPv4. Go figure.
Examples of addresses include:

Hexadecimal - 12:34:56:78:9A:BC

IPv4 (current standard) - 74.125.225.98

IPv6 (new format) - fe80::223:4eff:fec0:5b48


A Tale of Two Models

OSI is still used today to describe network communication and for standards to unite, while the TCP model is used to show relation between the various protocols it contains. Below is a diagram of how the two map out to each other.

✳️ Hack phone on the Emergency ✳️

Lockscreen hack exposes Android smartphones to full control by hackers.

A critical bug allows hackers to gain access to Android smartphones/tablets.

This Android smartphone hack affects all devices running versions of Android 5.x which means that a millions of Android smartphones in circulation worldwide are susceptible.

The process of attack :-

🔶 1 🔶 From the locked screen, open the EMERGENCY CALL window.

🔶 2 🔶 Type a few characters, e.g. 10 asterisks. Double-tap the characters to highlight them and tap the copy button.

Then tap once in the field and tap paste, doubling the characters in the field.

Repeat this process of highlight all, copy, and paste until the field is so long that double-tapping no longer highlights the field.

This usually occurs after 11 or so repetitions.

🔶 3 🔶 Go back to the lockscreen, then swipe left to open the camera.

Swipe to pull the notification drawer down from the top of the screen, then tap the Settings (gear) icon in the top right.

This will cause a password prompt to appear.

🔶 4 🔶 Long-tap in the password field and paste the characters into it.

Continue to long-tap the cursor and paste the characters as many times as possible, until you notice the UI crash and the soft-buttons at the bottom of the screen disappear, expanding the camera to fullscreen.

Getting the paste button can be finicky as the string grows. As a tip, always make sure the cursor is at the very end of the string (you can double-tap to highlight all then tap towards the end to quickly move the cursor there) and long-tap as close to the center of the cursor as possible.

It may take longer than usual for the paste button to appear as you long-tap.

🔶 5 🔶 Wait for the camera app to crash and expose the home screen.

The duration and result of this step can vary significantly but the camera should eventually crash and expose sensitive functionality.

You should notice the camera lagging as it attempts to focus on new objects.

Taking pictures via the hardware keys may speed up the process, though it is not strictly necessary.

If the screen turns off due to inactivity, simply turn it back on and continue waiting.

In some cases the camera app will crash directly to the full home screen as seen below, whereas other times it may crash to a partially rendered home screen as seen in this
alternate.

🔶6🔶 Navigate to the Settings application by any means possible, e.g. by tapping the app drawer button in the bottom center and finding it in the app list.

At this point it is possible to enable USB debugging normally (About phone > tap Build number 7 times, back, Developer options > USB debugging) and access the device via the adb tool to issue arbitrary commands or access the files on the device with the full permissions of the device owner.
