Re: Chegg Data Breach notification (Thanks to HIBP)

yes, yes, no.  For all similar reports that include a password in the
stolen data, we send this message to the affected accounts.
In April 2018, the textbook rental service Chegg suffered a data
breach
<https://techcrunch.com/2018/09/26/chegg-resets-40-million-user-passwords-after-data-breach/>
that impacted 40 million subscribers. The exposed data included email
addresses, usernames, names and passwords stored as unsalted MD5 hashes.

There are several things that you should do, depending upon your
circumstances:

  * If the password you used at Chegg was the same as your uni.edu
    CatID passphrase, you must change your CatID passphrase
    immediately.  To do that, login to the UNI portal/MyUNIverse and
    find the link in the "My Account" applet in the upper right corner
    of the screen.
  * If Chegg has provided information about changing your Chegg
    password, you should follow those instructions.  If you have not
    heard from Chegg about your stolen account information, you should
    login to the Chegg website and change your password now.
  * If the password you used on Chegg was also used on other sites,
    you should also change your password on those other sites.  It is
    never a good idea to share passwords between sites.  There are
    password managers that can help you maintain distinct passwords on
    different sites and also safely store those to enable easy access
    when needed.  Two examples that I use are LastPass and KeePass. 
    They have somewhat different functionality, but are both good options.


Thanks for your attention to this matter.

Feel free to steal and adapt as you wish.

Good morning folks,

I'm sure a bunch of you got similar notifications this morning that
$BIGNUM accounts at your domain were impacted by the April 2018 Chegg
Data breach.

We are looking at how we want to address this, as I'm sure that many
students use the same password everywhere.

have any of you decided how you are going to address this?
Are you notifying impacted users?
Are you requiring a password reset for campus systems?

Thank You
Frank
