## **Kutoa Data kutoka kwa Faili**
|
|
|
|
### **Binwalk**
|
|
|
|
Zana ya kutafuta faili za binary kwa ajili ya faili na data zilizofichwa ndani. Inapatikana kupitia `apt` na chanzo chake kinapatikana kwenye [GitHub](https://github.com/ReFirmLabs/binwalk).
|
|
```bash
|
|
binwalk file # Displays the embedded data
|
|
binwalk -e file # Extracts the data
|
|
binwalk --dd ".*" file # Extracts all data
|
|
```
|
|
### **Foremost**
|
|
|
|
Inarejesha faili kulingana na vichwa na miguu yao, muhimu kwa picha za png. Imewekwa kupitia `apt` na chanzo chake kiko kwenye [GitHub](https://github.com/korczis/foremost).
|
|
```bash
|
|
foremost -i file # Extracts data
|
|
```
|
|
### **Exiftool**
|
|
|
|
Inasaidia kuona metadata ya faili, inapatikana [hapa](https://www.sno.phy.queensu.ca/\~phil/exiftool/).
|
|
```bash
|
|
exiftool file # Shows the metadata
|
|
```
|
|
### **Exiv2**
|
|
|
|
Kama exiftool, kwa ajili ya kuangalia metadata. Inaweza kusakinishwa kupitia `apt`, chanzo kwenye [GitHub](https://github.com/Exiv2/exiv2), na ina [tovuti rasmi](http://www.exiv2.org/).
|
|
```bash
|
|
exiv2 file # Shows the metadata
|
|
```
|
|
### **File**
|
|
|
|
Tambua aina ya faili unayoshughulika nayo.
|
|
|
|
### **Strings**
|
|
|
|
Hutoa maandiko yanayosomika kutoka kwa faili, kwa kutumia mipangilio mbalimbali ya uandishi ili kuchuja matokeo.
|
|
```bash
|
|
strings -n 6 file # Extracts strings with a minimum length of 6
|
|
strings -n 6 file | head -n 20 # First 20 strings
|
|
strings -n 6 file | tail -n 20 # Last 20 strings
|
|
strings -e s -n 6 file # 7bit strings
|
|
strings -e S -n 6 file # 8bit strings
|
|
strings -e l -n 6 file # 16bit strings (little-endian)
|
|
strings -e b -n 6 file # 16bit strings (big-endian)
|
|
strings -e L -n 6 file # 32bit strings (little-endian)
|
|
strings -e B -n 6 file # 32bit strings (big-endian)
|
|
```
|
|
### **Comparison (cmp)**
|
|
|
|
Inatumika kulinganisha faili iliyobadilishwa na toleo lake la asili lililopatikana mtandaoni.
|
|
```bash
|
|
cmp original.jpg stego.jpg -b -l
|
|
```
|
|
## **Kutoa Takwimu Zilizofichwa Katika Maandishi**
|
|
|
|
### **Takwimu Zilizofichwa Katika Nafasi**
|
|
|
|
Makarakteri yasiyoonekana katika nafasi zinazonekana kuwa tupu yanaweza kuficha taarifa. Ili kutoa data hii, tembelea [https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder](https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder).
|
|
|
|
## **Kutoa Takwimu Kutoka kwa Picha**
|
|
|
|
### **Kutambua Maelezo ya Picha kwa GraphicMagick**
|
|
|
|
[GraphicMagick](https://imagemagick.org/script/download.php) inatumika kubaini aina za faili za picha na kutambua uwezekano wa uharibifu. Teua amri iliyo hapa chini ili kukagua picha:
|
|
```bash
|
|
./magick identify -verbose stego.jpg
|
|
```
|
|
Ili kujaribu kurekebisha picha iliyo haribika, kuongeza maoni ya metadata kunaweza kusaidia:
|
|
```bash
|
|
./magick mogrify -set comment 'Extraneous bytes removed' stego.jpg
|
|
```
|
|
### **Steghide kwa Kuficha Data**
|
|
|
|
Steghide inarahisisha kuficha data ndani ya `JPEG, BMP, WAV, na AU` faili, inayoweza kuingiza na kutoa data iliyosimbwa. Usanidi ni rahisi kutumia `apt`, na [kanuni ya chanzo inapatikana kwenye GitHub](https://github.com/StefanoDeVuono/steghide).
|
|
|
|
**Amri:**
|
|
|
|
* `steghide info file` inaonyesha kama faili ina data iliyofichwa.
|
|
* `steghide extract -sf file [--passphrase password]` inatoa data iliyofichwa, nenosiri ni hiari.
|
|
|
|
Kwa utoaji wa mtandaoni, tembelea [tovuti hii](https://futureboy.us/stegano/decinput.html).
|
|
|
|
**Shambulio la Bruteforce na Stegcracker:**
|
|
|
|
* Ili kujaribu kuvunja nenosiri kwenye Steghide, tumia [stegcracker](https://github.com/Paradoxis/StegCracker.git) kama ifuatavyo:
|
|
```bash
|
|
stegcracker <file> [<wordlist>]
|
|
```
|
|
### **zsteg kwa Faili za PNG na BMP**
|
|
|
|
zsteg inajikita katika kugundua data iliyofichwa katika faili za PNG na BMP. Usanidi unafanywa kupitia `gem install zsteg`, ikiwa na [chanzo chake kwenye GitHub](https://github.com/zed-0xff/zsteg).
|
|
|
|
**Amri:**
|
|
|
|
* `zsteg -a file` inatumia mbinu zote za kugundua kwenye faili.
|
|
* `zsteg -E file` inaelezea payload kwa ajili ya uchimbaji wa data.
|
|
|
|
### **StegoVeritas na Stegsolve**
|
|
|
|
**stegoVeritas** inakagua metadata, inafanya mabadiliko ya picha, na inatumia LSB brute forcing miongoni mwa vipengele vingine. Tumia `stegoveritas.py -h` kwa orodha kamili ya chaguzi na `stegoveritas.py stego.jpg` kutekeleza ukaguzi wote.
|
|
|
|
**Stegsolve** inatumia filters mbalimbali za rangi kufichua maandiko au ujumbe uliofichwa ndani ya picha. Inapatikana kwenye [GitHub](https://github.com/eugenekolo/sec-tools/tree/master/stego/stegsolve/stegsolve).
|
|
|
|
### **FFT kwa Ugunduzi wa Maudhui ya Fichwa**
|
|
|
|
Fast Fourier Transform (FFT) mbinu zinaweza kufichua maudhui yaliyofichwa katika picha. Rasilimali muhimu ni pamoja na:
|
|
|
|
* [EPFL Demo](http://bigwww.epfl.ch/demo/ip/demos/FFT/)
|
|
* [Ejectamenta](https://www.ejectamenta.com/Fourifier-fullscreen/)
|
|
* [FFTStegPic kwenye GitHub](https://github.com/0xcomposure/FFTStegPic)
|
|
|
|
### **Stegpy kwa Faili za Sauti na Picha**
|
|
|
|
Stegpy inaruhusu kuingiza taarifa katika faili za picha na sauti, ikisaidia fomati kama PNG, BMP, GIF, WebP, na WAV. Inapatikana kwenye [GitHub](https://github.com/dhsdshdhk/stegpy).
|
|
|
|
### **Pngcheck kwa Uchambuzi wa Faili za PNG**
|
|
|
|
Ili kuchambua faili za PNG au kuthibitisha uhalali wao, tumia:
|
|
```bash
|
|
apt-get install pngcheck
|
|
pngcheck stego.png
|
|
```
|
|

## **Kutoa Data kutoka kwa Sauti**
|
|
|
|
**Audio steganography** inatoa njia ya kipekee ya kuficha habari ndani ya faili za sauti. Zana tofauti hutumiwa kwa ajili ya kuingiza au kupata maudhui yaliyofichwa.
|
|
|
|
### **Steghide (JPEG, BMP, WAV, AU)**
|
|
|
|
Steghide ni zana yenye uwezo wa kuficha data katika faili za JPEG, BMP, WAV, na AU. Maelekezo ya kina yanapatikana katika [stego tricks documentation](stego-tricks.md#steghide).
|
|
|
|
### **Stegpy (PNG, BMP, GIF, WebP, WAV)**
|
|
|
|
Zana hii inafaa kwa aina mbalimbali za muundo ikiwa ni pamoja na PNG, BMP, GIF, WebP, na WAV. Kwa maelezo zaidi, rejelea [sehemu ya Stegpy](stego-tricks.md#stegpy-png-bmp-gif-webp-wav).
|
|
|
|
### **ffmpeg**
|
|
|
|
ffmpeg ni muhimu kwa kutathmini uadilifu wa faili za sauti, ikionyesha maelezo ya kina na kubaini tofauti zozote.
|
|
```bash
|
|
ffmpeg -v info -i stego.mp3 -f null -
|
|
```
|
|
### **WavSteg (WAV)**
|
|
|
|
WavSteg inajulikana kwa kuficha na kutoa data ndani ya faili za WAV kwa kutumia mkakati wa bit isiyo na umuhimu. Inapatikana kwenye [GitHub](https://github.com/ragibson/Steganography#WavSteg). Amri zinajumuisha:
|
|
```bash
|
|
python3 WavSteg.py -r -b 1 -s soundfile -o outputfile
|
|
|
|
python3 WavSteg.py -r -b 2 -s soundfile -o outputfile
|
|
```
|
|
### **Deepsound**
|
|
|
|
Deepsound inaruhusu usimbaji na kugundua habari ndani ya faili za sauti kwa kutumia AES-256. Inaweza kupakuliwa kutoka [ukurasa rasmi](http://jpinsoft.net/deepsound/download.aspx).
|
|
|
|
### **Sonic Visualizer**
|
|
|
|
Kifaa kisicho na thamani kwa ukaguzi wa kuona na wa uchambuzi wa faili za sauti, Sonic Visualizer inaweza kufichua vipengele vilivyofichwa ambavyo haviwezi kugundulika kwa njia nyingine. Tembelea [tovuti rasmi](https://www.sonicvisualiser.org/) kwa maelezo zaidi.
|
|
|
|
### **DTMF Tones - Dial Tones**
|
|
|
|
Kugundua sauti za DTMF katika faili za sauti kunaweza kufanywa kupitia zana za mtandaoni kama [hiki kifaa cha kugundua DTMF](https://unframework.github.io/dtmf-detect/) na [DialABC](http://dialabc.com/sound/detect/index.html).
|
|
|
|
## **Other Techniques**
|
|
|
|
### **Binary Length SQRT - QR Code**
|
|
|
|
Data za binary ambazo zina mraba kuwa nambari kamili zinaweza kuwakilisha QR code. Tumia kipande hiki kuangalia:
|
|
```python
|
|
import math
|
|
math.sqrt(2500) #50
|
|
```
|
|
Kwa kubadilisha binary kuwa picha, angalia [dcode](https://www.dcode.fr/binary-image). Kusoma QR codes, tumia [hiki kisoma barcode mtandaoni](https://online-barcode-reader.inliteresearch.com/).
|
|
|
|
### **Tafsiri ya Braille**
|
|
|
|
Kwa kutafsiri Braille, [Branah Braille Translator](https://www.branah.com/braille-translator) ni rasilimali bora.
