Static Parsing Steganography

Static Parsing Steganography (SPS) • The sender and the receiver agree on a cover image. • The protocol does not modify the cover image. • Rather determines the bits of the secret message that match the ones in the cover image and stores their different locations (i.e. in the cover image) in a vector. • Then it is sent to the recipient Fig.6. Key Based Steganography F. Static Parsing The static parsing method generally consists of two steps [i] Embedding the secret message and cover file and converting it into bits.

  2. Static Parsing Steganography (SPS) is based on parsing the image instead of modifying it. Divide-and-conquer strategy is the fundamental of SPS that finds the longest common substring from the message and image files. The process is repeated until all of the message bits matched to bits of the image

Our main goal in this paper is to give new insights and directions on how to improve existing methods of hiding secret messages, possibly by combining steganography and cryptography.

These modifications are generally imperceptible to humans, but are machine detectable public static int [] encode (String str) takes in a String and will return an int [] where each element is a single bit in the ASCII encoding of the String. Each character in str will encode into 7 bits, so the output array should be 7 times larger than str.length (). For example, encode (C) should output the array [ 1, 0, 0, 0, 0, 1, 1 Static Parsing Steganography Hikmat Farhat, Khalil Challita, Joseph Zalaket.

Steganography simply works this way: Start with a secret message using a previously agreed upon algorithm insert the secret message into a cover object creating the stego object. Then the stego object is sent to the to the receiver. The receiver accepts the stego object. The receiver extracts the hidden message using the agreed upon algorithm This is done by concealing the secret image within the lowest bits of the apparent image. Example of a cat hidden within a tree. I split it into 2 programs to make commandline args parsing easier, Crypt and Decrypt.

Lots of times functions inside a file are declared as static. Why??? What it does is restrict visibility of the function to the translation unit in which it's declared. Functions are implicitly declared as extern by default, which means they're visible across translation units. You can compile the following, but it won't link /* file1.

One common way to do steganography: Think about a 1024 x 768, 24-bit color (i.e. 8 bits of red, 8 bits of yellow, 8 bits of blue) image. Now, the least-significant bit of the colors in the image doesn't matter much. Therefore, one can hide three bits of information in each pixel

Parsing as Abstract Interpretation of Grammar Semantics; The primary application of abstract interpretation is to static program analysis undrstood as a static approximation of the dynmic properties of programs, as formalized by a collecting semantics. Steganography and abstract interpretation suspicious. Moreover, by using custom steganography algorithms on the images, detecting encoded malicious payloads with static detection is virtually impossible. We have already seen Remcos variants that used steganography to unpack code [5], but so far, the images have been embedded in the deployed executable file, not downloaded from Imgur

The latest instance of Cardinal RAT employs obfuscation in the form of steganography; the initial sample is compiled with .NET and contains an embedded bitmap (BMP) file. Upon execution, the malware will read this file, parse out pixel data from the image, and decrypt the result C.

The term for identifying a file embedded in another file and extracting it is file carving. One of the best tools for this task is the firmware analysis tool binwalk Introduction. In the last article, Steganography VI, only void methods could be used, so the length of the hidden message was very restricted. This article enhances the application: All methods with a return type of void, bool, int32 or string can be used. A key file defines how the message is hidden. The difference between void and non- void.
