Alert Priority High

Researchers have discovered that a well-known type of malware has been used to target password management tools.

Password management tools are an inevitable target for criminals because they hold a list of all your usernames and passwords, and many can also store credit card information and other personal details used for online shopping.

With information all stored in one place, it makes password management tools a potential single point of weakness. If it is compromised, so are all the accounts you have stored in it.

According to the researchers, the malware is a new version of Citadel malware. Citadel has previously been shown to have compromised millions of computers worldwide. It is effective at avoiding detection by security software, and has been used to steal banking passwords with great effect.

Because Citadel is already widespread, it is possible that the criminals could remotely reconfigure the malware that is already on people’s systems to target master passwords.

The new version of Citadel has been adapted to target the master password of your password manager. Under certain conditions it seeks to log the keys you type (record the keys when you press them) as you enter your master password.

Staying safe

To stay safe you should ensure your password manager is as secure as possible, and minimise the chances of encountering malware in your online activities.

Use a strong master password. If possible, you should also use ‘two-factor authentication’. The second factor, such as a code sent by SMS, means that a stolen password alone will not grant the criminal access.

You should also install reputable security software and keep it up-to-date.

Other ways you can minimise your chances of encountering malware and of being impacted by attacks such as this include:

Stick to reputable websites, software and services that are more likely to secure your information.

Do not click on links or attachments in emails, messages, posts or other communications unless you are confident about where it will take you or what it contains.

Be suspicious about emails and messages from sources you do not know.

Learn what to look for in messages that could be suspicious.

Minimise the amount of information you disclose online.
