Re: Dear RIPE: Please don't encourage phishing

The line gets crossed when you send an unsolicited message that includes a
clickable change password link, that a phisher would find interesting
to emulate.

After the fact, if a phisher gets one of your customers to click on such a
link, you'd like to tell them them in response, or preemptively, that your
company never asks for sensitive information via email.

With good policies in place, the customer should not be receiving clickable
links via email that ask them for a password, except for a scenario where
they've actively generated that email in response to an "I forgot my
password" link on a website.

So because of phishing, nobody should send messages with URLs in them?

I received the enclosed note, apparently from RIPE (and the headers check out).
Why are you sending messages with clickable objects that I'm supposed to use to
change my password?

[Apologies for duplicate e-mails]

Dear Colleagues,

We are contacting you with some advice on the passwords used in the RIPE
Database.  There is no immediate concern and this notice is only advisory.
At the request of the RIPE community, the RIPE NCC recently deployed an
MD5 password hash change.

Before this change was implemented, there was a lot of discussion on the
Database Working Group mailing list about the vulnerabilities of MD5
passwords with public hashes.  The hashes can now only be seen by the user
of the MNTNER object.  As a precaution, now that the hashes are hidden,
we strongly recommend that you change all MD5 passwords used by your MNTNER
objects in the RIPE Database at your earliest convenience.  When choosing
new passwords, make them as strong as possible.

To make it easier for you to change your password(s) we have improved
Webupdates.  On the modify page there is an extra button after the "auth:"
attribute field.  Click this button for a pop up window that will encrypt
a password and enter it directly into the "auth:" field.

Webupdates: https://apps.db.ripe.net/webupdates/search.html

There is a RIPE Labs article explaining details of the security changes
and the new process to modify a MNTNER object in the RIPE Database:
https://labs.ripe.net/Members/denis/securing-md5-hashes-in-the-ripe-database

We are sending you this email because this address is referenced in the
MNTNER objects in the RIPE Database listed below.

If you have any concerns about your passwords or need further advice please
contact our Customer Services team at ripe-dbm () ripe net   (You cannot reply
to this email.)

Regards,

Denis Walker
Business Analyst
RIPE NCC Database Group
