Some players are dedicated to collecting sets of epic gear while others prefer to make a few quick coins in the auction house. No matter what style of play you prefer, we want to equip you with the tools and knowledge you need to protect yourself against account compromise. To help get you started, below you'll find a series of tips and suggestions aimed at improving your account and computer security.
Since we’ve been encouraging account security awareness for quite a while now, you might have already run across some of this information on our Account Security Awareness page, in one of our support articles, or posted by your fellow players here on these forums. We want to make sure that as many players as possible have secure accounts, though, so we encourage you to take some time to read over this refresher, make sure your account is secure, and share these tips and resources with your friends and guildmates, too.
There are a few cardinal "rules" for maintaining a secure Battle.net account. They're simple and straightforward, but they can help ensure that your account information doesn't get into the wrong hands.
- Never give out your account information. Sharing account information with a family member, friend, guildmate or, worse, a stranger who's promising you a chance to "beta test a new mount" is an easy way to lose control of your account security and experience the tragedy of account compromise. Even if your goal is just to be helpful, allowing someone else to access your account can definitely put it at risk because you can't control how that person will make use of your account information, or how secure their own system might be.
- Be mindful of phishing scams. Phishing scams are designed to trick you into giving out your account information, and they'll usually come in the form of emails or in-game messages that appear to be sent by Blizzard employees. Sometimes these messages encourage you to visit a malicious website, which might contain a web form, or even software that can steal your login information. In other cases, you may be asked to reply with your account name and password.
While most of these types of scams are easy to identify -- they'll frequently use poor grammar and spelling, or make outrageous threats about banning your account -- some can be difficult to distinguish from legitimate Blizzard correspondence, so it's important to be cautious of what you click on and when. (Learn more about how to identify these kinds of scams here.)
Going The Extra Mile
In addition to following the security basics, you'll also want to make sure your computer is protected against malicious programs known as "keyloggers." Keyloggers are pretty serious, and they're capable of gleaning information directly from your computer, either by monitoring your keystrokes or by gaining access to important applications like your Clipboard.
The advice listed below will help you combat this type of security risk and maximize your computer's security.
- Grab an Authenticator. The Battle.net Authenticator and Mobile Authenticator are easy ways to add an additional level of security to your account. They work by providing a secure authentication code on command that's unique to your Battle.net account. After an Authenticator is associated with your Battle.net account, the authentication code will be necessary for each client and Account Management login, increasing your protection against account compromising attacks. (They also will provide your characters with an adorable Core Hound Pup companion.)
The Battle.net Dial-In Authenticator is another handy option. It's a free opt-in service that will actively monitor an account and request additional authorization from you when a potentially unauthorized login attempt occurs.
- Install antivirus and anti-spyware software. There are a number of programs that can help you identify and remove any viruses, Trojans, and/or keyloggers that may sneak onto your computer. If you're unsure of what software might be best for you, check out our support site for a list of recommendations.
Keep in mind that most antivirus and anti-spyware programs will periodically issue software updates to ensure that they're able to identify the latest malware threats, so be sure to install those updates before beginning any new system scans.
- Keep your operating system up-to-date. If you're using Windows, you can check for the most current updates at any time by visiting the Microsoft Windows Update page, or by clicking Windows Update in the Start menu. If you're a Mac user, you can check for software updates at Apple.com; Apple security updates are also available here.
- Keep your browser and browser plug-ins up-to-date. As with your anti-malware software and computer operating system, you'll want to keep your web browser as up-to-date as possible. In addition to providing more tools and functionality, browser updates can also include new security definitions and a more comprehensive phishing filter (detailed further below).
Using the most recent versions of your browser plug-ins and applications (like Adobe Flash Player and Adobe Reader) and regularly checking for security updates is also important, because they can sometimes become targets for certain types of malware. A lot of plug-ins and applications will prompt you to update automatically, but it's still a good idea to check the distributor websites on occasion to make sure you're running the latest versions.
- Turn on your browser's phishing filter. Phishing filters work by comparing the websites you visit against a massive database of legitimate (secure) websites and websites that have been identified as potential security risks. If you happen to visit a website that's flagged by your browser's filter, you'll be alerted and given the opportunity to continue onto the page or -- in most cases -- navigate to another site completely. Most popular browsers have built-in phishing filters that are turned on by default, but you can always double-check filter settings/availability in the Tools menu.
