  • How do you prevent other people from reading from your laptop screen while working on your highly sensitive documents in the train?

    The correct answer is to use a privacy screen.
    A privacy screen is a sheet of plastic that you can use to cover your screen. Only if you are sitting straight in front of the computer can you see what is on the screen. People next to you can’t see anything.

    Use a webcam-cover.
    A webcam cover prevents people who have hacked your computer to make a movie or take pictures even though they have access to your webcam.

    Use a laptop-sleeve.
    A laptop-sleeve is a protection against physical damage to your laptop.

    Use a firewall.
    A firewall protects you from hackers trying to access your system. A number of firewalls also protect programs and applications on your computer to send data to attackers. Ransomware often wants to communicate with the criminals who send it out. If the ransomware can't connect to the internet, it won't work because it can't inform it's makers.

  • How do you help criminals steal your identity?

    All answers are correct.

    Taking a picture of your passport and sharing it online.
    Your passport contains sensitive information that can be used by criminals to steal your identity. If you need to share an image of your passport, or give somebody a copy, the Dutch government has an app which help you remove the sensitive data from the image.

    Giving your driving license to a car dealer when you make a test drive.
    The car dealer, or one of his employees, can access the sensitive data on the driving license and use that to steal your identity. If you are stopped by the police while making the test drive you have to provide your license. If the car dealer needs some proof of your identity you can make a copy of the license with the app the Dutch government provides.

    Keeping the privacy settings of your Facebook account on default.
    In default settings Facebook allows not only your friends to access your data but also all kinds of other organisations like advertisers. Even criminals can get access to the information, like when you are not at home. Keep in mind Facebook changes the settings page regularly and often resets them back to default.

    Making a small payment (€ 0,01) to an unknown account at eBay.
    If you open a new bank account, the new back often asks to send a small amount. They check whether the name belonging to the old account matches the new. Criminals use this method to set up bank accounts on the victim’s names. If you make a payment the bank uses that as proof the new account belongs to you. Even if you know nothing about it.

    Using the same password on all your websites.
    Websites get hacked every week if not every day. If hackers find a list of e-mail addresses and passwords, they use them on all kinds of other websites to find out whether they can get in there too. Use different passwords, or better yet passphrases, for each website. If you can’t remember them all use a password manager.

  • How to recognize a phishing mail?

    The correct answer is all of them.

    An impersonal salutation.
    Criminals often don’t know who you are. They use an impersonal salutation, like “reader”, or none at all. Sometimes they use your e-mail address in the salutation.
    This doesn’t mean an e-mail with your real name in the salutation isn’t phishing. When they target you directly like this, we call this spear phishing. In that case they want something special from you and not just the general population. They will make an effort in getting to what and who they want.

    Spelling and grammar mistakes.
    In the past most phishing was performed by criminals in Africa with no knowledge of the Dutch language and barely any knowledge about the English. Today they often use professional translators or are native Dutch. That is most often true with spear phishing attacks.

    An unclear sender.
    If the criminal hasn’t hacked the account of the sender he has to impersonate that person. That is the hardest thing for a criminal to do.

    Requests for personal information.
    Criminals are after your personal information, whether that is your account credentials or other information they can use to steal your identity. Check whether the questions asked correspond with the sender normal intend. Would they ask these questions? Would they do it by email? Would they send you to a website to enter them?
