Consumers are having their Web browsing intercepted and Web sites are having their computer code altered by NebuAd, a company that provides targeted advertising for Internet Service Providers (ISPs), according to a technical investigation by Free Press and Public Knowledge.
NebuAd is an online advertising company whose partnership with cable and phone companies has raised substantial privacy questions for House Subcommittee on Telecommunications and the Internet Chairman Ed Markey (D-Mass.) and Rep. Joe Barton (R-Texas).
In a new report, “NebuAd and Partner ISPs: Wiretapping, Forgery and Browser Hijacking,” Robert M. Topolski, the chief technical consultant for the organizations, found that NebuAd uses special equipment that “monitors, intercepts and modifies the contents of Internet packets” as consumers go online. Topolski, the network engineer who made public Comcast’s throttling of BitTorrent applications, said in the report that “NebuAd commandeers users’ Web browsers” to load tracking cookies and collects information from users in order to place ads from ISPs.
“Apparently, neither the consumers nor the affected Web sites have actual knowledge of NebuAd’s interceptions and modifications,” the report found.
