 There have been papers attacking obfs4 and similar pluggable transports
 such as https://ieeexplore.ieee.org/document/8855280.

 The obfs4 maintainer (Yawning) also has said that the protocol is outdated
 and unmaintained which is not a good thing for something that is the
 primary pluggable transport for the Tor Browser.

 The Tor Project should initiate an effort to create a better, secure, more
 resistant and more up to date pluggable transport to replace obfs4.
