Help needed for identifying the hash type

[andiaa734]

first of all, the starting $6 and the rest seems more to look like a typical mode 1800 -> sha512crypt $6$, SHA512 (Unix) taken from a linux shadow file (but malformed)

example entry from a typical shadow file without any data

Code:

nobody:*:18375:0:99999:7:::

as you can see the  99999:7::: part is quite obvious

so in my opinion this is something taken from a shadow file and has nothing to to with DES as DES has to be of length 13

You are right. it is taken from a shadow file. After unsahdow it looks like this:
root:$6CJlS7VEVeK2:0:0:root:/:/bin/sh

But it doesn't makes it easier. I start to believe that the shadow file was somehow modified.
