Malvertising, which is a portmanteau of "malicious advertising," is an increasing danger in the digital sphere. It alludes to the practise of disseminating malware or malicious code via web marketing. Cybercriminals use trusted platforms and ad networks to disseminate their dangerous payloads to unwary victims. Malvertisements, which can be found on famous websites and look like legal advertisements, can lead users to malicious websites, start the download of files containing malware, or take advantage of security holes in the user's system when clicked or even just watched. Due to hacked ad networks, even trustworthy websites may inadvertently show harmful adverts, enabling the widespread distribution of malware. Users should make sure their devices have the most recent security software, think about utilising ad blockers, and be cautious when online to protect themselves from malvertising.
