Top 10 web hacking techniques of 2020
Summary: PortSwigger's annual community-voted Top 10 novel web hacking techniques of 2020 drew 54 nominated papers, posts and presentations, narrowed to 15 finalists by community vote and ranked by a panel of Nicolas Grégoire, Soroush Dalili, Filedescriptor and James Kettle. The winning entry was H2C Smuggling by Jake Miller of Bishop Fox, which abuses H2C-unaware front-ends to tunnel to backend systems, bypass front-end rewrite rules and reach internal HTTP headers.
Key Takeaway: The panel noted the best research increasingly dips below the application layer - abusing TLS, chunked encoding, PDF internals and packet fragmentation - and that request tunneling exploitation is an emerging art expected to produce serious carnage in future, which puts front-end proxies and load balancers in the blast radius.
