5 Unit 1 Living in the Digital WorldChapter 1 Lets Communicate Internet Safety Knowledge Spyware Spyware is a computer program which is installed without permission, sometimes through a virus or sometimes as part of the installation of a program. It works by collecting information and sending it back to another source. The information collected could include the websites you have been visiting or what you have been downloading. This information is often used for marketing purposes, but can also be used for illegal purposes such as fraud. Cookies A cookie is a small fi le which stores information related to your Internet activity and then reports this back to the website server. Cookies are used legitimately by website creators to enable websites to be customised for individual users. For example, if you go on to the BBC website, you can customise the homepage, and the next time you visit the site the layout will appear as you have set it. However, cookies can cause problems such as pop-ups being generated or details like passwords stored which could be used by hackers.

6 Unit 1 Living in the Digital WorldChapter 1 Lets Communicate Internet Safety Knowledge cont: Spam Spam is all unwanted email such as unsolicited commercial email, unsolicited bulk email and chain letters. Phishing Phishing involves sending a link via an email to a website which looks like a genuine website (e.g. a bank website) but is in fact bogus. The recipient may be tricked into following the link and entering details such as bank passwords or personal information on the website. Hackers It is important to keep the information that is stored on your computer secure. Hackers are people who try to get access to your computer without your permission in order to steal information which they could use for malicious or criminal purposes. Using peer-to-peer (P2P) software could increase the risk of hackers accessing data stored on your computer. Identity theft This takes place when someone collects personal information about you and uses that information for malicious or criminal purposes. In the past, criminals used to rummage though bins to get information, but now people can access Internet social networking sites where peoples profiles contain personal information, which could prove valuable to the criminals. Identity theft is a growing problem.
