Смысл: The text explains that Rostelecom's site-blocking mechanism relies on a predictable DPI signature. By subtly altering the HTTP request structure or filtering out the ISP's injected redirect packets, users can bypass censorship.
A technical guide explaining how to bypass Rostelecom's website blocking by manipulating HTTP headers or using iptables to drop ISP-injected redirect packets.
Смысл: The text explains Rostelecom's shift from crude IP-based website blocking to a more precise URL-based filtration system to comply with censorship requirements while avoiding the high costs of DPI technology.
Rostelecom is replacing IP-based blocking with a cheaper, URL-specific transparent proxy system instead of implementing expensive DPI technology.
Смысл: The text describes a technical discovery regarding a specific method used by Russian censors (Roskomnadzor/TSPU) to block TLS-based proxies by monitoring connection frequency and targeting specific hosting providers' IP ranges.
An investigation into a specific TLS proxy blocking mechanism used by Russian ISPs that triggers after multiple rapid connections to certain hosting providers.
