Ada presented their recent paper, “Rewriting History: Changing the Archived Web from the Present” at ACM CCS 2017 in Dallas, TX in early November. In this paper, Ada studied web archives, which are websites such as the Wayback Machine that allow anyone on the web to time travel and see what the web looked like decades ago. Through analysis of the design of web archives and their interactions with other web technologies, this paper demonstrated a number of techniques by which malicious parties could modify the web of the past, injecting their own deceptive content so that anyone visiting a web archive will see not the historical contents of the pages they view, but an attacker’s deceptive content. The work was performed with attention to ethics, and the results were disclosed to the staff at the Wayback Machine, who quickly deployed several effective defenses against the vulnerabilities discovered, giving this paper real world impact.
