It's an executable packed with UPX. Run: `upx -d journey`
You get an executable. It asks for a password. The password is the string that, when run against 0x328f3b67d25391, [Gronsfeld deciphers](http://rumkin.com/tools/cipher/gronsfeld.php) to "theresanotherstep"
```python#!/usr/bin/env python
target = 'theresanotherstep'x = 0x328F3B67D25391
pwd = ''for char in target:    y = x % 10    x //= 10    z = chr(ord(char) + y)    pwd += z
print('flag{%s}' % pwd)```
