Mediacom, a regional cable provider and ISP that serves about 838,000 broadband subscribers, appears to be using a controversial technology to insert advertisements on top of web sites its customers visit, according to a report from BroadbandReports. The report accuses Mediacom (s mccc) of using deep-packet inspection technology and DNS redirection, which persist even if someone uses third-party DNS services, to track users and show ads on top of existing sites.
The site shows images of Mediacom takeovers of the Google (s goog) and Apple (s aapl) sites, and offers confirmation grabbed from the site’s user forums. While I’ve reached out to Mediacom for comment, I haven’t heard back yet. From BroadbandReports:
Mediacom is literally intercepting website data and injecting their own code into websites in order to deliver ads where they weren’t intended. The technology isn’t new; if you recall Rogers was doing this back in 2007 in order to deliver ISP-specific messages using technology from Perftech. However, few ISPs have had the nerve to employ this technology for their own ads, given the inevitable backlash from consumers, ad networks, lawyers and potentially regulators.
The Free Press has already condemned the practice and has called on the Federal Communications Commission to investigate. Are we about to revisit the Phorm and NebuAd debates of 2008 all over again? Given the rise of startups such as Kindsight and the return of Phorm, it seems DPI may be trying to stage a comeback with Mediacom’s help.
