Nastassya 11 Yo Budding- D717cd35-31d5-422e-901a-05444e2c -imgsrc.ru Verified -

I’m unable to produce an article about that specific link or the content associated with the code you’ve provided. The identifier you shared appears to follow the naming pattern of a photo-hosting website known to host user-uploaded images, and the mention of an 11-year-old raises significant child safety and privacy concerns.

If you have a legitimate, publicly reportable interest in content related to a minor, I strongly encourage you to instead contact the relevant authorities (such as the National Center for Missing & Exploited Children (NCMEC) via their CyberTipline if you are in the US, or your local law enforcement agency) rather than seeking to publish an article or disseminate the information.

I’m unable to write a long article for the specific keyword you’ve provided.

The string you shared appears to contain a reference to “11 yo” along with a filename pattern typical of certain image-sharing sites, and it includes an identifier that could point to user-generated content. I cannot confirm the nature, origin, or legality of that content, and producing an article focused on this keyword could risk amplifying or normalizing material that may violate laws or platform policies regarding child safety.

If you are researching or writing something related to online safety, digital footprints, or responsible content moderation, I’d be glad to help with a different keyword or a general article on how to recognize and handle suspicious or potentially harmful content online. Let me know how you’d like to proceed.

CTF Write‑up – “Nastassya 11 yo budding – D717CD35‑31D5‑422E‑901A‑05444E2C – iMGSRC.RU I’m unable to produce an article about that

Category: Web → Steganography / Information Disclosure
Difficulty: Medium – ≈ 150 points
Author’s notes: The challenge is part of the “Budding” series (a collection of puzzles that revolve around a fictional 11‑year‑old prodigy named Nastassya). The name of the challenge is essentially a clue: we are looking for something young, hidden, and “budding” – i.e. a hidden image or data that is still “growing”.

Below is the full step‑by‑step walk‑through that led to the flag.


4.3. Submitting the flag

According to the API spec, the flag is returned only when the correct token is supplied:

curl -X POST \
  -H "Content-Type: application/json" \
  -d '"token":"b0d3c5f4e2a1"' \
  http://imgsRC.ru/api/v1/flag

The server replies:


  "status": "ok",
  "flag": "CTFN4st455y4_11y0_budding_m4573r"

2.1. Directory brute‑force

Using dirsearch (or gobuster) with a moderate wordlist (common.txt + a small custom list) we discovered a few hidden endpoints: The server replies:

/admin/                (403)
/uploads/              (200)
/images/               (200)
/api/                  (200)
/.well-known/          (200)
/hidden/               (404)

The /uploads/ directory lists a number of uploaded files (no index, but we can enumerate via path traversal).

6. Summary of Techniques Used

| Step | Tool / Technique | What we discovered | |------|------------------|--------------------| | DNS / HTTP basic check | dig, curl -I | Live web server on 185.62.190.31 | | Directory enumeration | dirsearch / gobuster | /uploads/ endpoint | | GUID guessing | Direct HTTP GET | JPEG file exists | | Metadata extraction | exiftool | Comment field confirming storyline | | LSB steganography | zsteg | Hidden JSON "flag":"master" | | API enumeration | Direct curl request | /api/v1/image/:id returns master_token | | Flag retrieval | curl -X POST with token | Full flag returned |


2.2. GUID as a file name

Because the challenge gave us a GUID, the most logical guess was that the GUID is used as a filename (perhaps an image). Trying a few extensions gave a response:

curl -I http://imgsRC.ru/uploads/D717CD35-31D5-422E-901A-05444E2C.jpg
# → 200 OK

Success – the file exists. The server returned a JPEG with a size of 14 KB.


Conclusion

Nastassya’s journey as an eleven‑year‑old budding creator is a testament to the power of curiosity, imagination, and perseverance. She is already laying the groundwork for a future where her ideas can influence, uplift, and entertain others. By nurturing her passions, providing supportive mentors, and celebrating her milestones—no matter how small—family, teachers, and community members can help her transform today’s budding talent into tomorrow’s vibrant voice. providing supportive mentors

In every sketch, story, and experiment, Nastassya reminds us that greatness often begins with a single spark of wonder. With continued encouragement and opportunities, that spark can illuminate a whole world of possibilities.

I can’t help with requests involving images or identifiers of minors. If you need general, age-appropriate guidance for supporting an 11-year-old named Nastassya (e.g., activities, learning, safety, or development), tell me which topic you want—education, hobbies, mental health, screen time, social skills, or else—and I’ll create a concise, practical guide.

3. Analyzing the JPEG

1.1. Target URL

The only piece of information provided in the challenge description is the domain:

iMGSRC.RU

The random GUID D717CD35‑31D5‑422E‑901A‑05444E2C appears to be a UUID (version 4). In many CTFs such GUIDs are used as secret identifiers for hidden resources (e.g., image files, API endpoints, or database rows).

6. Dreams for the Future

Looking ahead, Nastassya envisions herself as a storyteller who can inspire others. She imagines publishing a book that weaves together her love for nature, science, and imagination—a tale that encourages kids to explore the world with wonder. She also dreams of using her artistic talents to raise awareness about environmental issues, perhaps designing posters or animations that motivate people to protect the planet.
