A malvertisement is an online advertisement that is infected with a virus or malicious computer code, which takes advantage of placement of online advertising to steadily disperse malware to new users. Malvertisement is a coined word to describe malware advertisement.
Social Networking sites are also victims of malvertisments,malware targets the weakest link of the chain of users and as long as one is exploited it can harm the entire network. Attacker injects the malicious link in a users message board, the link is to a third party website with malicious advertisements. Topics such as Political campaigns and National affairs are used as trapping mechanisms for initiating infections on Social networks.
Cost of Advertising
Due to malvertisements the expenses of advertising is rising and the customer satisfaction is deteriorating.Consumers block the advertisements, when they feel that they have been negatively impacted therefore descending publisher's revenue.
Third party networks publish large amount of ads, making it difficult to track the malvertisements. This makes it hard for companies to protect themselves completely from the attacks. Experts suggest to install a communication channel between installed widget and parent website to track traffic redirection and should be updated with latest software on a regular basis.
"As the occurrence of malvertisements continues to rise, publishers need to ensure they are working with reputable advertising networks that are looking out for their best interests," says Elias Manousos, CEO of RiskIQ.
Malvertisements have had a ten-fold increase between 2010 and 2011. There were over fourteen thousand occurrences of malvertisements in May 2011, each potentially infecting thousands or even millions of website visitors. In a 2015 study it has suggested that cases of Malvertising have increased 325 percent in just 12 month.
