Malvertising (a short form of “malicious advertising”) refers to a method in which online advertisements are deliberately misused to spread malware (malware). The ads seem harmless at first glance and often even appear on reputable websites, but contain hidden malicious code. <\/p>

<\/h4>

What exactly is malvertising?<\/strong><\/h4>

In malvertising, cybercriminals place manipulated advertisements via common advertising networks. These ads are then displayed on many different websites \u2013 often without the knowledge of the site operators. The malicious function can either be activated by clicking or triggered automatically, for example when the ad is displayed and the system has an unpatched security vulnerability. <\/p>

Potential impacts include:<\/strong><\/p>

  • Infection with malware (e.g. through drive-by downloads)<\/p><\/li>

  • Redirecting to fraudulent or fake websites<\/p><\/li>

  • Presentation of manipulated alerts (“Your device is infected”)<\/p><\/li>

  • Reading or tapping access data<\/p><\/li><\/ul>

    <\/h4>

    Where do I encounter malvertising in the everyday work of SMEs?<\/strong><\/h4>

    Malvertising can occur in many places in everyday office life \u2013 especially where employees surf the Internet:<\/p>

    • On news portals, specialist websites or blogs that integrate advertisements<\/p><\/li>

    • When visiting online tools or services funded by advertising<\/p><\/li>

    • In search results that show purchased ads<\/p><\/li>

    • In free applications funded by embedded advertising<\/p><\/li><\/ul>

      <\/p>

      Especially in SMEs, where private and professional Internet use are sometimes mixed, the risk of accidentally encountering harmful content is particularly high.<\/p>

      <\/h4>

      What can I do to protect myself?<\/strong><\/h4>

      To reduce the risk of malvertising, companies and employees should implement the following measures:<\/p>

      • Update software regularly (operating system, browser, plugins)<\/p><\/li>

      • Use ad blockers in your browser to suppress malicious ads<\/p><\/li>

      • Use only official and trustworthy sources for software and downloads<\/p><\/li>

      • Use antivirus and security software that scans websites and downloads<\/p><\/li>

      • Raising employee awareness of cyber risks and fraudulent online advertising<\/p><\/li>

      • Avoid suspicious websites, especially with unusually cheap offers or eye-catching advertising messages<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
