Website-Targeted False Content Injection by Network Operators
summary
Study monitors web traffic from three networks serving >75,000 users and analyzes about 1.5 petabits to find races where two TCP packets share the same sequence number but carry different payloads, signaling out-of-band injection. Analysis groups detections into 14 injection groups (eight ad injections, four malicious, two blocking), locates injectors 2–5 hops from targeted servers using a TTL heuristic, finds most injections are transient (days) and publishes representative samples plus client-side mitigation ideas.
