Find me on:

 As you may or may not have heard, Yahoo announced on December 14, 2016 that it suffered a data breach that includes data from upwards of One billion user accounts.

You may be thinking, wait, I already know about the Yahoo data breach announced back in September. Well hold on because that breach, which included about 500 million accounts, was a completely separate incident that actually happened in 2014. 

According to the information released on December 14th this data breach occurred 2013 but wasn't discovered until 2016.

Sophos 7 Deadly IT Sins

If you have a Yahoo account, we would recommend the following:

  1. Change the password and security question answers on your Yahoo account(s) immediately.
  2. If you used the password and/security question answers from your Yahoo account on any other online accounts, you should update those immediately as well.

In addition to those steps you should consider:

  1. Enabling multi-factor authentication(called two-step authentication by Yahoo) for your Yahoo account as well as other online accounts such as Facebook, Google, Twitter, and of course on your business account where available.
  2. Use a password managersuch as LastPass, 1Password, or Dashlane.

As important as anything else, stay vigilant. Tricks like spoofing email addresses and phishing emails are techniques and tools we see being used by bad actors on the daily basis. Unexpected emails, even from a known person or company, requesting information like logon credentials or with attachments could very easily be a hacker's way of opening a door into your personal or corporate information.
