steganography apps for mobile devices( which are freeee..)

Secrets can be embedded within photo and audio files by replacing the least essential code with bits of the hidden data. Developers have come up with a wealth of applications that can do this work from mobile devices and many of them are free..

Concealment: From Lakeside Llama this iOS app lets you take a picture and hide a secret message inside of the image (up to three hidden images). These images can then be stored in the in-app photo library, the device  photo library, iMessage (iOS 5) or be emailed directly to whomever one is sending the message to, the company says.


Hide It In: Hide It In is an app that hides an image taken with your iPhone camera into another seemingly innocuous image from your photo library that can be sent by email. Select the cover image and take a picture with your phone.  Developed by Jorge Blasco, Hide It In features among other things, AES encryption to ensure that even if the presence of a secret message is suspected, only password holders will be able to recover the hidden image .

Acoustic Picture Transmitter: According to developer Dominik Siebold, this app lets you transmit and receive images acoustically. To do this each column of the selected message gets transformed by a Fast Fourier Transform and outputted through iPhones speaker. On the receiving iOS-device the received audio is visualized by a spectrogram and the incoming images become visible. You can use this app for example to transmit images very easily over a phone or to put images in every kind of audio recording.

How to know whether your LinkedIn password is hacked

So here’s how to check if your LinkedIn password was among the hacked accounts that are already being used to generate phishing attacks. Go to

Enter your password, and the website will tell you whether or not your password is now out in the wild. The obvious question: is it safe to give LastPass your password?

Here’s what the company says about their tool:

"Only the hash of your password will be sent to’s servers, not your actual password. This hash will not be stored or logged at all. Please view source the page if you’re technically inclined."

One caveat: because the search will look through all the passwords in the file, if you have a very common word or password, it will come up as compromised. For example, here’s what LastPass shows when the all-too-common password “password” is entered:

This does not mean your account is compromised, necessarily. It does mean your password is too common and should be changed. Ultimately, of course, we should all be smarter about passwords and use a tool like LastPass or 1Password to make sure we have complex and unique passwords for every single service and site we use.

LinkedIn breached: 6.5 million passwords compromised

Attention LinkedIn users, your privacy has been breached. Millions of internet users can now see your password posted online. We request you not to be under false pretenses that you are safe from this epidemic. LinkedIn has already confirmed this news and has stated that passwords that are reset will now be stored in a salted format, which technically means that passwords are in an encrypted format AND adjoined with a random bunch of characters to make the password-cracking process a pain-in-the-neck for the hacker.

According to Imperva:

The passwords weren't properly protected.  The hashes, in geek speak, were unsalted sha1 hashes.  Not salting is a bad practice that we detailed in last month’s report on the Military singles breach.   Salting, in layman’s terms, complicates the process of a hacker cracking a password.  Not only do you encrypt the password, but append it with a random string of characters so even if those passwords are revealed, they look like gobbledygook.

LinkedIn was probably breached but the password database doesn’t indicate this specifically.  Many of the passwords contained a high volume of the word, or a variation of the word, “linkedin”.  This indicates that the pool of passwords comes from LinkedIn, though the hacker hasn’t specifically made such a connection.  The password set shows:

  • 13 passwords contained “linkedin”
  • 509 passwords contained “linked”
  • 1134 passwords contained “link”

Imperva suggest that the list of the security breach could be much larger than the already whooping number of 6.5 million. They have provided two reasons for their theory:

1. The list doesn't have any easy passwords such as 123456 (which is the most used password in the history of passwords) included.

2. All passwords are listed only once, leaving us to a guessing game wondering how many times was a certain password used.

After this massacre, SophosLabs geniuses did a little research of their own, testing which passwords were commonly used among the 6.5 million users and should never be used by anyone. Their study suggested that only 2 passwords of the 6.5 million passwords were unique and not used by anyone else. "mypc123" and "ihavenopass" are the lucky winners of the day. Unfortunately, these, too, were cracked and exploited.
