Mailchimp Says It Was Hacked

If you subscribed to the DAILY (not the weekly) email messages listing new articles posted to this web site in the previous 24 hours, please pay attention to this:

The DAILY (not the weekly) email messages are sent by Mailchimp.  (It is a service I pay for.)

Mailchimp recently said in a blog post that its security team detected an intruder on January 11 accessing one of its internal tools used by Mailchimp customer support and account administration. Mailchimp said the hacker targeted its employees and contractors with a social engineering attack. The hacker then used those compromised employee passwords to gain access to data on 133 Mailchimp accounts, which the company notified of the intrusion. 

NOTE: I have not received any notification from Mailchimp so I assume (I hate the word “assume” but it is appropriate right now) that subscribers to this newsletter’s DAILY (not the weekly) email messages were not part of the affected 133 Mailchimp accounts. 

Mailchimp also states that no customer passwords or other sensitive data was taken.

So while we can assume (there’s that word again) that subscribers to’s DAILY (not the weekly) email messages are not affected by this, I still want to warn subscribers that there is still a POSSIBILITY  that your email address and password were accessed.

If you subscribe only to the WEEKLY email updates (usually mailed on Mondays in the mid-day U.S. time), Mailchimp is not involved in those mailings (sent from a different mail server owned by a different company) so you can safely ignore this message.
