Password managers are a hot topic of discussion in the world of IT security. But what exactly is a password manager, and more importantly, is it really helping you keep your data secure?
Passwords, we all have them, and use them daily in from work through to personal and social accounts and websites. Everyone knows about the importance of password security, keeping it private and difficult to guess, (goodbye password123) but with so many, it can be hard to keep track of which password is used for which website, application or account.
This is where a password manager can help. A password manager remembers each of your passwords and automatically attributes them to the right website, account or application. Meaning you no longer have to remember which password you’ve used for the dozens of websites and application you use. With a password manager, you can sit back and never have to worry about remembering that super secure password you set for your Amazon or Netflix account - leaving you free to plan your next holiday, or check out the latest cat video on YouTube.
While password managers can be great - they can certainly play an important part in keeping your data safe online and offer a useful alternative in managing your passwords - according to Marek Toth, a penetration tester at Avast, they are not without their own potential security flaws. In a recent blog post, marektoth.com Marek outlines why you should be disabling the autofill function in your password manager.
But what is autofill? Autofill is when your password manager enters your username and password for the website, account, or application you are logging into. Before getting into the nitty gritty, it is important to note there are two different types of autofill – manual and automatic.
If you are prompted to do something, such as click a button, to enter your username and password, this is a manual autofill action. If your username and password are automatically added, without you having to click a button, or do anything, this is an automatic autofill action.
It is this automatic autofill action that could leave you exposed, and leave the door open for cyber criminals to make off with the login details that you’ve spent so long making secure.
But I have anti-virus installed on my machine, how are they getting my details? You are not in fact, being hacked, or have a virus on your machine. These scamps and scallywags build malicious scripts which can read what is being entered on your screen by the automatic autofill function of the password manager and save what is being entered. From there, they can log into your various websites and accounts, using your username and password.
What do I need to do to prevent this? There are several steps you can take to keep yourself and your data as secure as possible. To try and prevent your data being read, however, the best thing you can do, is disable the autofill function on your password manager and/or web browser. How to do this, will depend on the password manager you are using, but if you get stuck, get in touch with Mark One, and we will be happy to help you out.
