{% endhint %} ## **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 [] ``` ### **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 ``` ### **Zana Zingine za Uchambuzi wa Picha** Kwa uchunguzi zaidi, fikiria kutembelea: * [Magic Eye Solver](http://magiceye.ecksdee.co.uk/) * [Image Error Level Analysis](https://29a.ch/sandbox/2012/imageerrorlevelanalysis/) * [Outguess](https://github.com/resurrecting-open-source-projects/outguess) * [OpenStego](https://www.openstego.com/) * [DIIT](https://diit.sourceforge.net/) ## **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. ## **Marejeleo** * [**https://0xrick.github.io/lists/stego/**](https://0xrick.github.io/lists/stego/) * [**https://github.com/DominicBreuker/stego-toolkit**](https://github.com/DominicBreuker/stego-toolkit) {% hint style="success" %} Jifunze & fanya mazoezi ya AWS Hacking:[**HackTricks Training AWS Red Team Expert (ARTE)**](https://training.hacktricks.xyz/courses/arte)\ Jifunze & fanya mazoezi ya GCP Hacking: [**HackTricks Training GCP Red Team Expert (GRTE)**](https://training.hacktricks.xyz/courses/grte)
