### Challenge Description

> I'm not sure where I lost my car, but I believe I’ll remember if I can see the original photo again. Can you find it? I only have this photoshopped and cropped version, but I’m confident it contains enough information for an OSINT expert. To prove your success, submit a flag with the Build Number from the EXIF data in the format: `1753c{Build Number}`.

***

### Provided Image

### Step 1: Checking Metadata

I used `exiftool` to examine the metadata of the provided image:

```bash
exiftool dude-where-is-my_car.jpg
```

**Output (trimmed):**

```
...
File Name                       : dude-where-is-my_car.jpg
File Size                       : 1828 kB
Image Size                      : 2132x2040
MIME Type                       : image/jpeg
...
```

Unfortunately, **no useful EXIF data** (like GPS or device info) was found.

***

### Step 2: Reverse Image Search

I uploaded the image to **Google Image Search**.

After skimming through the results, **nothing matched exactly**. So, I analyzed the image further myself.

***

### Step 3: Analyzing Visual Clues

While inspecting the image, I spotted a **URL on the license plate**:

<figure><img src="/files/k0pLpfFCCJYT0nQQBL4g" alt="" width="375"><figcaption></figcaption></figure>

```
www.lieberzupiper.de
```

Visiting the URL directly didn’t work (domain is offline), so I searched for `lieberzupiper de` on Google.

<figure><img src="/files/fLl4LU0Ii5AoTQiKdWvX" alt=""><figcaption></figcaption></figure>

Bingo! I found a listing on:

```
https://tablica-rejestracyjna.pl/WWY?p=373
```

Unfortunately, it didn’t have the full original image either.

***

### Step 4: Exploring the Site

I clicked on **"Więcej komentarzy »"**, which led to:

```
https://tablica-rejestracyjna.pl/komentarze/WWY
```

There, I browsed through the pages manually until **I found the original image on page 3**.

Downloaded it and prepared to analyze its metadata.

***

### Step 5: Extracting the Flag

Ran `exiftool` on the downloaded original image:

```bash
exiftool original-car-photo.jpg
```

**This time I got the jackpot:**

```
...
Build Number                    : S2RUBS32.51-15-3-19
...
```

***

### Step 6: Submitting the Flag

I submitted the flag using the required format:

```
1753c{S2RUBS32.51-15-3-19}
```

**Correct!**

### Final Flag

```
1753c{S2RUBS32.51-15-3-19}
```
