What Lawyers Can Learn from the Yahoo Email Hack

Yahoo, the second largest email service worldwide, reported a security breach last untitledweek which exposed personal information from sent email folders.

The Associated Press reports:

Yahoo Inc. said in a blog post on its breach that “The information sought in the attack seems to be the names and email addresses from the affected accounts’ most recent sent emails.”

That could mean hackers were looking for additional email addresses to send spam or scam messages.  By grabbing real names from those sent folders, hackers could try to make bogus messages appear more legitimate to recipients.

If you correspond with friends, family, clients, or colleagues who use Yahoo’s mail service, scrutinize incoming e-mail carefully to avoid phishing scams. 

This breach has another takeaway for lawyers – you are only as secure as your third party vendors.  The Yahoo and Target breaches were both the result of third-party vendor hacks.  In the case of Yahoo, the information was collected from a third-party database.  In the Target hack, credentials were stolen from a third party vendor.

Lawyers should take this to heart when evaluating their own cyber liability and security – specifically with regard to HIPAA compliance.  If your servers are hosted in the cloud, or you use cloud-based practice management, accounting, or backup solutions, inquire into the security procedures of your vendors.  Remember that encryption is your friend.  All data stored in the cloud should be encrypted – minimally by your vendor.  Better yet: go the extra mile.  Seek out cloud providers who permit you to add your own third party encryption, like Viivo or TrueCrypt, so that you (and only you) hold the final encryption key.
