Scam of the day – February 4, 2014 – What does the Yahoo email breach mean to you?

A few days ago, Yahoo announced that its email security had been breached.  Yahoo is the second largest email provider with approximately 273 million users.  The actual breach which involved the theft of both usernames and passwords was accomplished not by hacking Yahoo directly, but rather by hacking a third party website’s database that allowed the use of Yahoo email addresses to establish customer accounts.  Similarly, the recent breach of Target also appears to have been accomplished by hacking into a Target vendor’s systems to obtain the credentials necessary to, in turn breach the security of Target.  Many people may not be particularly alarmed that all was taken in the Yahoo hacking were usernames an passwords, however, because people often use the same user name and passwords for multiple accounts, including online banking, the threat posed by this hacking could be quite serious.  In addition, these usernames and passwords could be used by identity thieves for “spear phishing” a technique by which identity thieves are able to send specifically targeted messages to potential victims that appear to come from trusted sources thereby making the potential victim more likely to click on a link or download an attachment in the email that would be riddled with malware that will steal all of the information from a person’s computer or other electronic device and use that information to make the person a victim of identity theft.

TIPS

If you haven;t already done so, change your username and password for Yahoo email if you are a user of Yahoo email.  Even if you are not a Yahoo email user, you should make sure that all of your online accounts have different user names and passwords because the risk of your being a future victim of a similar type of data breach is very high.  It is a good idea to change your passwords every few months and make sure that the password is at least eight characters long and is a mixture of letters and symbols.  For tips on how to pick a good password, check out my book “50 Ways to Protect Your Identity in a Digital Age.”
