MAJINAHANASHI
We entered. We looked around. We took what was there.
This is the report.
--------------------------------------------------------------------------
WHAT WE DID
Files were encrypted where they sat. A unique key per
file, wrapped under an offline key that leaves with us
when this is over. Backups and shadow copies were
removed because they get in the way.
No files were deleted. No data was corrupted. Every
byte can be recovered.
--------------------------------------------------------------------------
WHAT WE TOOK
A copy of your internal data was extracted during the
process. This is not a threat - it is a statement of
fact. We have it. You do not.
If an agreement is reached, all copies are destroyed
and you receive written confirmation. If no agreement
is reached, the data finds new owners.

Send 2 files. We decrypt them. This is not a
negotiation tactic - it is verification that we
hold the keys and that recovery is possible.
Once you have proof, we talk.
No intermediaries. No recovery consultants. No law
enforcement liaison. Every person you add to this
conversation is another person who knows what
happened here.
