A US Senator trying to eradicate the Internet scourge known as malvertising is proposing that all federal agencies block ads delivered to worker computers unless advertisers can ensure their networks are free of content that contains malicious code.

In a letter sent today, Oregon Senator Ron Wyden asked White House Cybersecurity Coordinator Rob Joyce to begin discussions with advertising industry officials to ensure ads displayed on websites can’t be used to infect US government computers. If, after 180 days, Joyce isn’t “completely confident” the industry has curbed the problem, Wyden asked that Joyce direct the US Department of Homeland Security to issue a directive “requiring federal agencies to block the delivery to employees’ computers of all Internet ads containing executable code.”

“Malware is increasingly delivered through code embedded in seemingly innocuous advertisements online,” Wyden wrote. “Individuals do not even need to click on ads to get infected: this malicious software, including ransomware, is delivered without any interaction by the user.”

You have to figure that there is a LOT of people who surf the web during their lunch hour, and if ads are blocked, internet firms will take a major hit.
