Home security App using Camera

Want to know what is happening at your home after you left,if you have old phone lying around you can make it a home monitoring device.

Setting up a simple home security camera is a great way to keep tabs on your house while you’re away. A dedicated system is great, but in a pinch, you can use an old, spare smartphone that you have lying around.

You could, of course, buy an indoor security camera that’s ready to set up and actually made for such a purpose. Something like the Nest Cam is a good option, but $200 can be a little steep. Instead, if you upgrade to a new smartphone every year, it’s likely that you have an old, spare smartphone just collecting dust in a drawer somewhere. You can put it to good use by turning it into a home security camera.

This process relies on an app called Manything, which you install both on your old phone (the camera) and on your current phone (which allows you to view the camera). The app is available on iOS and Android, although the Android version is still in beta. Thankfully, it’s rather complete for being just a beta, and it should work just fine on most Android devices. Try it out first to ensure the camera functionality works on your device.

Manything is free to use for 1 camera and no cloud recording. But Manything also has paid tiers that you might be interested in. When you first sign up, you’ll get a free month of Manything’s best plan, but after that, you can either use their free plan or go with a cheaper paid plan. Here’s what Manything offers:

The $2.99/month plan isn’t a bad way to go. It provides one camera and stores your recordings for up to two days, which is plenty of time for you to view and save them.

Once you download and install the app on your spare smartphone, tap on “Register” at the bottom to get started.

Enter in your email address and create a password to use with Manything. Tap on “Register” when done.

Next, tap on “Camera”.

You might get pop-ups of the app asking permission to access your phone’s camera and microphone. Tap “OK” on these.

After that, the camera interface will pop up. You can begin right away by pressing the red record button to begin monitoring your home. From here, you can prop up your smartphone against a ledge of some sort, or get a small tripod and phone holder. Something like the Joby GripTight Micro Stand would be perfect. You’ll also want to make sure that the phone is plugged into a power source so that its battery doesn’t die during the day.

With that set up, download and install the Manything app on your main smartphone. The app works cross-platform, meaning that you can have an Android device set up as a camera and an iPhone as the viewer, or vice versa. When you open the app, tap “Log in” at the bottom and enter in the email address and password you signed up with.

Tap on “Viewer”.

The spare smartphone that you set up should show up in the list.

Tapping on it will bring up the viewer where you’ll get a real-time view of what’s going on. You’ll also see a list of recordings below that if motion was detected. These recordings are uploaded to the cloud (a.k.a. Manything’s servers).

Tap on the gear icon in the top-right corner to view settings.

Most of the settings are self-explanatory, but there are some that deserve some explanation.

For instance, “Stills Mode” will have the camera take continuous pictures instead of recording video, which can help on bandwidth if your Wi-Fi isn’t up to snuff.

Under “Video Quality”, you can determine the quality of the video that gets streamed. If your Wi-Fi is kind of slow, it may be best to keep this on a low setting, but if you have a faster Wi-Fi connection, feel free to crank up the quality as you see fit.

Manything can stream and record over a cellular connection, but it’s generally a good idea to keep “Allow Cellular Data” disabled so you don’t bust through your monthly data allowance. However, you can still view the live stream and recordings from your viewer phone over a cellular connection

Lastly, tap on “Screen Dimmer” and make sure that “Bright On Movement” is disabled. This makes sure that the screen of the phone doing the recording and monitoring doesn’t come on when it detects motion. It’s not a huge deal, but it’s a quick way to save energy.

After you have the settings the way you want, you can sit back and wait for notifications to roll in whenever the camera detects motion. It will automatically begin recording when this happens (if you have a paid subscription) and save the recordings so that you can view them later.

C++ program to print a heart

Today I am going to demonstrate how to print a heart in c++ using predefined spacing methods.

So here is the program to print heart shape with happy friendship day message inside it. You can give this as a gift to your programmer friend. If you like it, don’t forget to share it!

OUTPUT

//Code in Dev C in Windows

#include "iostream"

#include "cmath"

using namespace std;

int main()

{

    double x, y, size=10;

    char ch=3;

    string message(” Happy Friendship Day “);

    int print_line = 4;

    if (message.length() % 2 != 0) message += ” “;

    for (x=0;x<size;x++)

    {

        for (y=0;y<=4*size;y++)

        {

            double dist1 = sqrt( pow(x-size,2) + pow(y-size,2) );

            double dist2 = sqrt( pow(x-size,2) + pow(y-3*size,2) );

            if (dist1 < size + 0.5 || dist2 < size + 0.5 ) {

                cout << ch;

            }

            else cout << ” “;

        }

        cout<<“n”;

    }

    for (x=1;x<2*size;x++)

    {

        for(y=0;y<x;y++) cout << ” “;

        for (y=0; y<4*size + 1 – 2*x; y++) { if (x >= print_line – 1 && x <= print_line + 1) {

                int idx = y – (4*size – 2*x – message.length()) / 2;

                if (idx < message.length() && idx >= 0) {

                    if (x == print_line) cout<<message[idx];

                    else cout << ” “;

                }

                else cout << ch;

            }

            else cout << ch;

        }

        cout<<endl;

    }

    return 0;

}

The default program prints the Message Happy Friendship day even though it is not today. 

well you can use it to impress your girl.

How to put text on the image using PHP

In this article I am going to demonstrate you how to put text on the image using php.

Easily create an image with text written on it using PHP imagettfbbox. This function requires both the GD library and the FreeType library.

Replace variables with your own, PHP script will take care of rest..

<?php

$image_width        =   500; //image width

$image_height       =   150; //image height

$font_color         =   array(0, 0, 0); //RGB color

$background_color   =   array(152, 183, 236); //RGB Color

$font_size          =   10; //size of font

$text_rotation      =   0; //text rotation value

$margin_left        =   10; //margin left

$margin_top         =   20; //margin top

$font               =   ‘verdana.ttf’; //font path

$string             =   “This is the string\nwritten on the image.”;

//create 300×300 pixel image

$new_image  = imagecreatetruecolor($image_width, $image_height);

$font_color             = imagecolorallocate($new_image, $font_color[0],$font_color[1],$font_color[2]);

$background_color       = imagecolorallocate($new_image, $background_color[0],$background_color[1],$background_color[2]);

// Set background color

imagefilledrectangle($new_image, 0, 0, ($image_width–1), ($image_height–1),$background_color);

$Text = imagettfbbox(0, 0, $font, $string);

imagettftext($new_image, $font_size, $text_rotation, $margin_left, $margin_top, $font_color, $font, $string);

//output image

header(‘Content-Type: image/jpeg’);

imagepng($new_image);

imagedestroy($new_image);

?>

First up we need to specify the dimensions of the image hence we declare them in the variables later we specify the RGB color and assign it to a variable now we get to the font size of the text to be displayed on the image and we also declare the size, margins ,font and Finally the message to be displayed

Now we create an image using the method in PHP and we set it with a background color Finally we redirect it with a header redirect.

The First Official Bitcoin Exchange Ever called Bitstamp

Bitcoins have been around for some time but are not widely accepted. Yesterday, one of the centers of European financial world, Luxembourg grants licence to Bitstamp  to operate through out the Europe. This makes Bitstamp operate widely as a public currency for the first time ever.

The  licence goes official from July 1st, 2016 and can be used in all the 27 European countries due to the Union’s inter-state agreements.

Bitstamp was founded by Nejc Kodric and Damian Merlak in August 2011 in Slovenia. They later moved their operations to the UK in April 2013. Since it’s  inception, the service has suffered many DDoS attacks and even a cyber-heist in the winter of 2015, when a phishing incident led to attackers stealing over 19,000 Bitcoin from users.

Despite the heavy attacks on them, the company recovered fast and in 2014, they requested an official permit from Luxembourg authorities, a center of the international financial world.  The company recovered and passed all security tests from Luxembourg’s CSSF and even an external financial audit from Ernst & Young, a reputable global company that provides advisory, assurance, tax, and corporate transaction services. The Luxembourg license Bitstamp has received today allows the company to legally trade Bitcoin in and to any of the fiat (de-facto) currencies in the EU’s 28 states. Until now, most Bitcoin exchanges have operated through intermediaries such as credit unions and banks.

Untill yesterday, we only have a Bitcoin-US Dollar exchange system. Along with today’s news, the company has also announced an immediate Bitcoin-Euro trading option.

So far, Bitcoin has raised over $10 million (€9 million) in investments. Based on its transactions volume, Bitstamp was considered the third-largest Bitcoin exchange. After today’s announcement, it an be easily said that Bitstamp will see a growth in popularity and numbers.

Forgot to tell you, while Bitcurrency was becoming official in Europe, usage of any such currency is still a big crime and leads to many years sentence to jail in Germany.

Top 10 vulnerabilities in 2015 are due to Flash

The annual report of software exploits of 2015 is out and it gives some shocking results. Usually attacks were more focused on Java security flaws but in the past year, exploit kit makers have switched from targeting Java security flaws to exclusively exploiting weaknesses in the Adobe’s Product, a recent report from the NTT group shows.

According to the security firm, all of the top 10 vulnerabilities targeted by exploit kits during 2015 were Flash flaws. According to historical records kept by the NTT Group, 2015 was the first year when exploit kits used more Flash flaws compared to Java, which almost disappeared from exploit kits altogether. This change in trends comes after Java was 2012, 2013, and 2014’s most targeted technology via exploit kit vulnerabilities.

Besides this Adobe product, in 2015, the second and third most targeted technologies were Internet Explorer and Microsoft Windows.

The main reason behind this trend is because of the massive security updates Java received in 2014 which made exploitation much difficult. Hackers turned their focus on Flash, which saw four zero-days in 2015 only from the Hacking Team data breach alone.

A similar report released by Symantec two weeks ago also confirms this trend. Symantec says that Flash vulnerabilities accounted for 17 percent of all zero-days in 2015, with four of the top five most used zero-days in 2015 belonging to Flash.

With so much material to work with and with Java’s extremely hard-to-bypass security features and dwindling market share, it is to no surprise that Flash usage in exploit kits has grown so much. The security upgrades that contributed to Java’s downfall from exploit kit arsenals are the click-to-play feature and Oracle’s decision to block unsigned applets by default.

In order, the top 10 Flash vulnerabilities used in exploit kits last year are as follows: CVE-2015-0311, CVE-2015-5119, CVE-2015-5122, CVE-2015-0359, CVE-2015-0313, CVE-2015-2419, CVE-2015-3090, CVE-2015-3113, CVE-2015-0336, CVE-2015-7645, and CVE-2015-3105.

How to make a Walking Robot at home

Robots are the building blocks of Modern Technology. Either in Industries or Firm all are controlled by Bots. So why don,t we make at home 

Watch us making a bot at home :

USING KALI LINUX HIDING SECRET MESSAGES IN IMAGES

Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos, meaning ‘covered, concealed, or protected’, and graphein, meaning ‘writing’. The first recorded use of the term was in 1499 by Johannes Trithemius in Steganographia, a treatise on cryptography and steganography which was disguised as a book about magic (Wikipedia). 

The general concept is hiding messages that overtly appear to be (or be part of) something innocuous such as images, articles, shopping lists, or a cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography lack a shared secret key and are forms of security through obscurity, whereas key-dependent steganographic schemes adhere to Kerckhoffs’s principle. For more information about this please seehttps://en.wikipedia.org/wiki/Kerckhoffs%27s_principle. 

The advantage of steganography over cryptography is that the secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages, no matter how unbreakable, arouse interest and may be incriminating in countries where encryption is illegal or encryption keys are required to be accessible 

Thus cryptography is the practice of protecting the contents of a message, whereas steganography is concerned with concealing the fact that a secret message is located within the message content. 

Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding within the transported medium, such as a document file, an image file, a program, or a protocol. Media files are ideal for steganographic transmission because of the potentially large size, which makes detection difficult. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet. This is a technique that is so subtle it would be almost impossible to notice unless looking directly for this adjustment. 

Part II: Steganography in Action Using Kali Linux 

NOTE: steghide only works with AU, BMP, JPEG, or WAV files. If you want to use a different file format, you will need to use a different tool. 

To hide your secret messages inside images, you will need to download some tools. A popular tool I like to use is Steghide which you can install on Kali Linux. 

Here are the steps to using the tool: 

Step 1: Installing Steghide 

You will need to install a tool that lets you hide messages. You only have to install the tool one time and it is not provided as an included module with Kali Linux. 

apt-get install steghide M11 

Step 2: Create a text file with your hidden message 

After you get comfortable with Steghide you can use more advanced command line features, but for now let’s simply create a text file with our hidden message. Feel free to use a text editor of your choice. I simply used vi to create a text file called my_secret.txt with the message, “My voice is my passport”.

My file is now saved along with the image file I am going to use.

Next we will use steghide to embed the hidden message into the graphic file. The graphic file I used was a simple drawing of my home lab network. As you can see it is an ordinary .jpg file. 

Step 3: Using Steghide to hide your message 

We will use a couple of basic options with Steghide:

1. embed –ef is option to embed the secret message txt 

2. -cf is image file we will use 

3. jpg is a pic file which obfuscates the message

You’ll see a line to input a password or passphrase within the terminal screen. Create one you can remember or do the unthinkable and write it down. We then successfully embed the message into our image, thus hiding secret the message. You can also compare the original file to the stenographic file, which is now considerably larger than the original. The hash values of the modified file and the original file are now different as well:

Step 4: Reading the embedded secret message 

Okay, now that we know how to hide a message, how do we read the message from the image file? We will use the extract –sf command: 

steghide extract –sf attack_lab.jpeg

Increase Your WiFi Speeds With These Simple Tweaks

Almost everyone have internet access these days and internet over WiFi is the most commonly used process. But what if your WiFi connectivity is not good ?. Here is how you can increase your WiFi speeds by some of these simple tweaks hope you like them 

Make sure that your router is in the right place 

If you have some dead zones in your house, your router may be in the wrong spot. The perfect place for a Wi-Fi router is in the center of your room at least a few feet above the ground. No matter what, do not hide it in the closet as it weakens the signal. 

Find an ideal Wi-Fi channel 

Choosing the right Wi-Fi channel will help you to reduce interference and improve the signal. The most frequently used channels that do not overlap with each other are 1, 6, and 11. If you are a Mac user, you have a special option called integrated Wireless Diagnostics feature that recommend the best channel depending on the connected router. 

To access it: 

1. Press the Option key. 

2. In the upper-right corner of the window, click the Wi-Fi icon. 

3. In the dropdown menu, find “Open Wireless Diagnostics”, and then select Utilities.

4. On the Wi-Fi Scan tab, click Scan Now to view the Wi-Fi channels that you should be using. 

Change your Wi-Fi channel 

You will need to login to your router as admin with the appropriate password, and then change the channel settings. The location depends on the type of router that you have. If a channel is already fixed, move five channels away, that is, if it is on channel 1, move to 6 or 11. You will then have to specify that fixed channel on all connecting devices. 

Switch to 5GHz band 

Usually routers have two frequency band settings: 2.4GHz (for long-range signal) and 5GHz (for short-range signal). If you pick the 5GHz band, it will reduce the number of people with unauthorized access. In this way you will prevent wide broadcasting. 

Reboot your router 

As in case with other electronics, when a router is on for a while, it will tend to stop performing at its best. Rebooting your router can fix Internet connection problems and improve slow moving connections. 

Comment below if I missed any points.

Any Android Phone Encryption Technique

Google introduced full-device encryption back in Android Gingerbread (2.3.x), but it has undergone some dramatic changes since then. On some higher-end handsets running Lollipop (5.x) and higher, it’s enabled out-of-the-box, while on some older or lower-end devices, you have to turn it on yourself.

Why to Encrypt a phone:

Encryption stores your phone’s data in an unreadable, seemingly scrambled form. (To actually perform the low-level encryption functions, Android uses dm-crypt, which is the standard disk encryption system in the Linux kernel. It’s the same technology used by a variety of Linux distributions.) When you enter your PIN, password, or pattern on the lock screen, your phone decrypts the data, making it understandable. If someone doesn’t know the encryption PIN or password, they can’t access your data. (On Android 5.1 and above, encryption doesn’t require a PIN or password, but it’s highly recommended since not having one would reduce the effectiveness of the encryption.)

Start by heading into the Settings menu and tapping on “Security,” again keeping in mind that the wording may be slightly different. If your device is already encrypted, it will show up here. Some devices will also allow SD card contents to be encrypted, but by default Android just encrypts on-board storage. If the device isn’t encrypted, you can start the process by tapping the “Encrypt phone” option.

he next screen will present a warning to let you know what to expect once the process is finished, most of which we’ve already talked about in this article. If you’re ready to proceed, hit the “Encrypt phone” button.

The phone will then reboot and start the encryption process. A progress bar and estimated time till completion will show up, which should at least provide an idea of how long you’ll be without your beloved handset. Just wait, it’ll all be okay soon. You can do this. You’re strong. Once it’s finished, the phone will reboot and you’re back in business. If you set up a lock screen password, PIN, or pattern, you’ll have to put it in now so the device will finish the boot process. If you haven’t set up a PIN or password, now is a good time to do so. Head into your device’s Settings > Security menu. From there, select the “Screen Lock” option (keep in mind that the wording may be slightly different for non-stock Android handsets, like Samsung Galaxy devices).

Choose Pattern, PIN, or Password to set your security.

You’ll be asked if you want to require the PIN, password, or pattern at startup. This is up to you, but we recommend choosing yes, since this increases the security of your device.

Note that even with a fingerprint reader, you can’t use a fingerprint to unlock a device on first boot—you’ll have to put in the password, PIN, or pattern. After the device has been decrypted with the correct security unlocking method, the fingerprint reader can be used to unlock the screen moving forward. From now on, your device will be encrypted, but if you ever want to disable it, you can do so by performing a factory reset. If you have a newer device that has encryption enabled out of the box, there’s no way to remove said encryption—not even with a factory reset.

Havij, an SQL Injection Interface

Havij SQL injection Tool 

1. There is a free version HERE, but your probably want to look around and see if you can get your hands on the full-version. 

2. A SQL vulnerable test site (we recommend something like DVWA).

3. A very important thing you will need: your mind.

Checking for SQL vulnerability 

Now to check is this site vulnerable to a verbose SQL injection, a hacker will simply add ‘ (apostrophe) after the site url like this: 

http://site.com/products.php?id=2′ 

and the hacker will get this error on the site 

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘\” at line 1.

It means that site is vulnerable to SQL injection.

Exploiting the vulnerable site 

1. Open Havij and paste site url in target field and hit enter. 

2. Now wait for Havij to get all the databases of the website. 

3. Now the hacker clicks on available database of site and click on Get Tables. 

Here, they select 535480_toyonorte for this site like in this image:

1. By clicking Get Tables Havij will look after the tables available in the database. 

2. Now after the scanning Havij will get all tables, now the main work will start , they must check if there table available with a name that has something to do with admin, users and something similar. Here, we have a table called usuario in this website. It is selected and then click on Get Columns.

1. Now after clicking Get Columns havij will get all the columns available in users table. 

2. In this case, the hacker found different columns like id, login, pass and many more. 

3. Now select the columns and click on Get Data like in pic given below.

Now havij will look after the data available in columns login and password i.e admin username and password like i getusername –> adminpassword–> 21232f297a57a5a743894a0e4a801fc3 (in encrypted form)Such as in the image below:

1. Now after they have found the username and password there is a problem. The password is encrypted in md5 language , so the hacker must crack it . 

2. To crack encrypted password the hacker copies the password click on MD5 tab in havij and paste the encrypted password in MD5 hash field and hit start. Now havij will try to crack the password.

1. Now they get the Password cracked for admin. 

2. The hacker will check for admin panel where they will login with username and password. 

3. To find admin panel click Find Admin tab in Havij and click start. 

Now havij will check the admin panel of website. In this case, they found http://site.com.co/admin/ as admin panel and open it in a web browser. They login with username and password and now they have control of the website

Java code for Screenshot

There might be a situation where you guys want to take screen shots programmatically. So I am sharing a program that help you to take screen capture of your screen and save it in PNG (Portable network graphic) picture format. 

The below program uses Java.awt.Robot class to capture the screen pixels and uses Imageio to save it as PNG image format. Just copy and paste the program in Notepad, save it and run the program to take screen shot.

import java.awt.Rectangle;

import java.awt.Robot;

import java.awt.Toolkit;

import java.awt.image.BufferedImage;

import java.io.*;

import javax.imageio.*;

class Snap

{

 public static void main(String args[]) throws Exception

 {

  Robot awt_robot = new Robot();

BufferedImage Entire_Screen = awt_robot.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));

  ImageIO.write(Entire_Screen, "PNG", new File("Entire_Screen.png"));

 }

}

Note: The Screen shot image will be stored at the location where your program is stored.

Download Entire Website using foca

FOCA is an excellent website reconnaissance tool with lots of interesting features and capabilities. Remember, before attacking any website or domain, it is critical to gather as much information as possible. From this information, you can determine the attack that is most likely to work against that site or network.

Step 1: Downlaod FOCA for Windows 

 Step 2: Choose Where You Save Results 

When you install FOCA, you will greeted with a screen like that below. The first task we need to do is to start a new project and then tell FOCA where we want to save our results.

I created a new directory at c:\foca and will save all my results there. Of course, you can save your results wherever is convenient for you, or use the default temp directory.

                                                           Step 3: Create a Project

In this tutorial, I will be starting with a project named after the information security training company, SANS, which is located at sans.org, and I will be saving my results to c:\foca.

Step 4: Getting the Metadata 

Once I create my project, I can go to the object explorer to the far left and select Metadata. This enables us to pull the metadata from the files on the website that contain metadata. Files such as .pdf, .doc, .xls, etc. all contain metadata that could be useful in your hack of your target. 

When you select metadata, you will pull up a screen like that below. In our case here, we will be searching sans.org for .doc files, so the syntax to be placed in the search window is: 

site:sans.org filetype:doc 

This will search the entire sans.org website, looking for .doc files. When I hit the Search button next to the window, it will begin to search and find all the .doc files at sans.org.

Of course, if you were searching for .pdf files or other filetypes, you would put in that filetype. You can also search for multiple filetypes by listing them after filetype, such as: site:

sans.org filetype:pdf,doc,xls

Step 5: Download the Files 

Once FOCA is done retrieving a list of all the .doc files, we can then right-click on any file and download the file to our hard drive, download all the files, or analyze the metadata. I chose to download all the .doc files I found at sans.org.
