 Yep, that's a flag: **ph0wn{M@st3r0f3wireMem0ry!}**
 
+Since the writing of this blog post, [bvernoux](https://twitter.com/bvernoux) added the `hd` feature in the 3-wire mode, allowing us to directly parse the hex content into string. The code has been added in this commit [a6019f4236758cf5ad19ba2d7b386f706f8cb303](https://github.com/hydrabus/hydrafw/commit/a6019f4236758cf5ad19ba2d7b386f706f8cb303), upgrade your HydraBus to benefit from it 🤩
