Malvertising is a term made up of the words “malware” and “advertising”. It refers to the use of online ads to download and execute malicious software (malware) on the user’s computer.
Malvertising attacks can be carried out in various ways. One example is the placement of malicious ads on legitimate websites visited by users. These ads can either be downloaded automatically when the user clicks on the ad or when the user moves the mouse over the ad.
Another example of malvertising is the use of fake banner ads that look like legitimate ads but actually contain malware. These ads are often placed on unreliable or unsafe websites.
Malvertising is a serious threat to computer and internet security. It can lead to malicious software being downloaded onto the user’s computer, which then steals data, consumes system resources or opens the computer to remote access by cybercriminals.
To avoid malvertising attacks, users should ensure that their antivirus and firewall software is up to date and that they regularly install security updates for their operating systems and applications. In addition, users should be careful which websites they visit and which ads they click on, especially on unsafe or unreliable websites.
