# easter egg
Description:
```
There's a flag hidden on this website, can you find it?

(No brute force required. The flag is not on any teams page, you don't need to check any page that starts with "https://fbctf.com/teams/")
```

After searching `fb{` on all pages, found nothing

But searching for `{` found something interesting on `careers` page:
```html

Facebook's Application Security team<span>{</span>is seeking a passionate hacker to help us secure over 2 billion users....
```
And searching for `}`:
```html

The Oculus Security Engineering team designs, builds, and supports the infrastructure and services<span>}</span>that allow Oculus to move fast,...
```
Also found `<span>f`, `<span>b` etc...

I wrote [quick python script](solve.py) to combine all characters together:
```python
import re
text = open("careers",'r').read()
text = re.findall('''<span>(.)</span>''',text)
print ''.join(text)
```

## Flag
> fb{we're_hiring}</span></span>
