Experts: Online advertising delivers maximum amount of malicious code

Security experts have claimed in a report that the online advertising mechanism has become one of the most effective tools to deliver malicious code to the web users.

Security firm Finjan found in their research that hackers are increasingly relying on tempering with targeted advertising services to deliver their code to thousands of sites out there.

Finjan warned in their report that these kinds of tempered advertising is just as likely to be accessed through legitimate commercial websites as through disreputable sites.

Finjan chief technology officer Yuval Ben-Itzhak added: ” The fact that malicious code is just as likely to be found in legitimate categories as in questionable categories means that security products that rely solely on URL categories to block access to malicious sites are no longer effective.”
