Update: Likely Data Security Breach at iContact.com

Submitted by maz on Thu, 01/28/2010 - 12:00

On the day I posted Suspected Data Security Breach at iContact.com I was contacted via Facebook by someone with an email address @icontact.com. I forwarded them the same information that I sent to their abuse team. I’ve not heard anything back since.

Others have picked up on this likely breach at iContact.com:

iContact have answered some concerns: they are looking into the problem.

I have been contacted by one of the sites/services whose address-list has been breached, simply to ask to be kept in the loop with iContact.com’s response.

I have done some further research into my mail folders. I have found one address which iContact.com have on record which has not yet received any spam. As a result, this address hasn’t been compromised and has been replaced by HIDDEN on this public website. iContact’s abuse team has been provided with the full details, however:

This address hasn’t received any emails this month:

The last email sent to this address was via iContact.com on 17th July 2009:

At first I wondered if the anomalous address, HIDDEN, was an indicator that perhaps only addresses recently sent a newsletter by iContact.com had been breached (i.e. those contacted after 17th July 2009). The counter-example is macheist.com@maz.nu which has been receiving emails only via Google’s mailers since April 1st 2009, so that theory doesn’t hold water. However, it would appear that not all of my addresses on file at iContact have been spammed yet, so perhaps this isn’t a total breach… or perhaps I’m still waiting for HIDDEN to be hit!
