rm: remove write-protected weird file

We have an account that was compromised and can not remove a couple empty files that were left there.


This is ls:

?--------- 256 root disk 0 Dec 31 1969 blankpage.php

This is stat:

File: `blankpage.php'
Size: 0 Blocks: 550 IO Block: 4096 Unknown
Device: 303h/771d Inode: 2241481 Links: 256
Access: (0000/?---------) Uid: ( 0/ root) Gid: ( 6/ disk)
Access: 1969-12-31 19:00:00.000000000 -0500
Modify: 1969-12-31 19:00:00.000000000 -0500
Change: 1969-12-31 19:00:00.000000000 -0500

attempt at rm
rm blankpage.php
rm: remove write-protected weird file `blankpage.php'? y
rm: cannot remove `blankpage.php': Operation not permitted

chattr has no effect on file (setting -i) etc.
chmod, chown, chgrp not permitted

Any Ideas?
