Cyber Security Lesson Brief from the Under Armour Breach

The Under Armour breach provides lessons in the do’s and don’ts of enterprise cyber security and compliance with the EU GDPR

Last week, athletic apparel manufacturer Under Armour announced that its popular MyFitnessPal weight loss and fitness tracking app had been hacked, compromising 150 million accounts. The Under Armour breach is the largest data breach so far this year and ranks among the top five to date. It also makes a good case study in the do’s and don’ts of enterprise cyber security. Let’s examine the lessons enterprises can take away from the Under Armour breach and its fallout, especially as the deadline for the EU GDPR approaches on May 25.

Cyber Security Lesson Brief from the Under Armour Breach

If a breach does happen, prompt disclosure is crucial.

The Under Armour breach was discovered on March 25 and disclosed only four days later; compare this to Equifax, which waited several weeks to notify users it had been hacked (and then chose to do so while the nation’s attention was focused on Hurricane Irma), and Uber, which waited more than a year (after attempting to cover the breach up). Prompt disclosure is going to be even more important under the GDPR, which will require organizations to report breaches within 72 hours.

Segment your data, and collect only the data you need.

The Under Armour breach involved only user names, email addresses, and encrypted passwords. The MyFitnessPal app does not collect Social Security numbers or other government identifiers, and payment information is stored separately, in a part of the system the hackers did not breach.

The GDPR requires organizations to bake data security into their products, policies, procedures, and systems from day one. While network segmentation alone does not constitute data security, it goes a long way towards demonstrating due diligence.

The GDPR will also require organizations to provide users with a plain-language explanation of what user data they are collecting and what they intend on doing with it. If you don’t absolutely need a particular piece of personal information to conduct your business, don’t collect it.

Properly encrypt and salt user passwords.

This is where Under Armour dropped the ball. The company states that while “the majority” of the compromised passwords were hashed using the robust bcrypt hashing function, at least some of the passwords were hashed using the notoriously hackable SHA-1 function. Under Armour has not disclosed why only some of the passwords were encrypted with bcrypt. It also has not specified whether the bcrypt-hashed passwords were salted for extra protection, which involves appending random data that is unique to each user and saving it along with their password.

To properly protect user passwords and fulfill the security requirements of the GDPR, make sure you are using a robust hashing function and salting user passwords. As strong as bcrypt is, it is not unbreakable; the Ashley Madison hack involved 36 million passwords hashed using bcrypt.

Do not reuse passwords.

Although the Under Armour breach yielded “only” email addresses and login credentials, not payment data or sensitive personal data like Social Security Numbers, a lot of people use the same set of login credentials on multiple sites. Armed with these credentials, hackers could attempt to use them on banking, shopping, or social media sites and to access victims’ email accounts. This underscores the importance of using a different, strong password for every system, website, and app.

If you have a MyFitnessPal account, you should log in and change your password right now. If you reused your MyFitnessPal password on any other sites, make sure to change those, too.
