The Quiet Side Channel... Smuggling with CL.0 for C2

Shows how a CL.0 request-smuggling desync against CDN-fronted sites can poison the shared cache so a chosen string is stored in a 3xx Location redirect header. Reading and writing encoded data through that poisoned redirect turns trusted, whitelisted domains into a stealthy command-and-control channel.
