* https://gfw.report/blog/gfw_looking_glass/en/ * Heartbleed-like memory disclosure (out-of-bounds read) in GFW's DNS parser. Worked circa 2010, doesn't work now. * https://www.sciencedirect.com/science/article/pii/S0167404820300626 * "Protocol Proxy: An FTE-based covert channel" * We present a proof-of-concept format transforming encryption (FTE)-based covert channel for tunneling TCP traffic through protected static protocols. Protected static protocols are UDP-based protocols with variable fields that cannot be blocked without collateral damage, such as power grid failures. We (1) convert TCP traffic to UDP traffic, (2) introduce observation-based FTE, and (3) model interpacket timing with a deterministic Hidden Markov Model (HMM). * Open access copy: https://sci-hub.se/http://www.sciencedirect.com/science/article/pii/S0167404...
