Edward Snowden has strongly criticised online ads, and advised Internet users to employ an ad blocker to protect their privacy online.
"Everybody should be running adblock software, if only from a safety perspective.
"We’ve seen internet providers inserting their own ads into your plaintext http connections.
"Because if the service provider is not working to protect the sanctity of the relationship between reader and publisher, you have not just a right but a duty to take every effort to protect yourself in response," he told online publication The Intercept.
A "malvertising" attack occurs when an ad network unknowingly hosts harmful files which are disguised as ads.
These types of attack have increased over the last few months, with one making the headlines when it infected Yahoo's website.
Most news sites employ dozens of trackers and cookies that gather information about personal web browsing habits which can be used for advertising purposes.
Documents leaked by Snowden showed that the National Security Agency has collected information directly from the data centers of Google and Yahoo by tapping links between the companies' servers.
Such security concerns have contributed to the growing popularity of ad blockers recently.
Publishers are concerned as they rely on advertising for their livelihood, and say that if users wish to avail of free content they have to put up with pop up ads.
However those in favour of ad blockers argue that Internet users shouldn't be forced to view ads that drain excessive amounts of their data usage and may even serve as a conduit for malware.
