Last week, the Division of IT sent an e-mail to the GW community regarding the recent discovery of 1.4 billion stolen credentials(usernames and passwords). The purpose of this blog post is to discuss the risks associated with credential re-use and things you can do to minimize the chances of your GW credentials being used by unauthorized persons. We wanted to take a moment to elaborate on the nature of this threat and how "credential dumps" can impact you and your online safety.
As you may have heard, large websites like Adobe.com, LinkedIn.com, and Yahoo.com have all suffered major cyber incidents in the last few years. A common hallmark of these incidents is that attackers steal the usernames and passwords for users of these sites and then leak the credentials publicly. There's very little that any regular user can do to prevent these types of incidents from occurring, but there are some actions that you can take to safeguard your accounts and your data. The most recent credential dump referenced in the above article is a collection of credentials gathered from numerous hacks.
Follow these guidelines to help protect your accounts:
1.) Check haveibeenpwned.com* to see if any of your e-mail addresses are associated with any large credential breaches. This site is operated and maintained by Troy Hunt, who is a well-known, reputable computer security expert.
Simply type your e-mail address, click the "pwned?" button and see a list of any websites where your e-mail address and password has been part of a known credential breach.
Feel free to share this URL with your family and friends.
2.) It is important that you do not re-use passwords. For example, if I use my GW e-mail address to register for Pinterest.com, the password used should not be the same as the password that you use with your GW e-mail address. This way, if Pinterest is ever compromised, that password is essentially useless for anything other than Pinterest. If you have trouble remembering passwords (this applies to roughly 99.9% of all people including the author) use a password manager. While not officially supported by the GW Division of IT, we like LastPass. LastPass works on PCs and Macs, as well as mobile devices that run iOS and Android. Password managers help users manage unique, long, complex passwords in an efficient manner.
3.) Choose passwords that are long (the longer the better) and complex (no dictionary words). Easily guessable passwords or passwords that employ obvious obfuscation techniques (e.g. Ra1seH1gh!) are not great passwords. While GW does not require you to change your password, it's not a bad idea to change your password periodically. There are some competing schools of thought on this issue but the GW security team recommends changing your password at least once annually.
The GW information security team is always on the lookout for notices of public credential dumps. We may tell you about these from time to time, especially if we learn that you may have been impacted by one of these dumps. In the meantime, follow the above guidance. These little things will go a long way to protect your accounts and your data from an attacker.
* - "pwned" is hacker-speak for "owned" or compromised.
