We hypothesise that the production of fully entangled sheep is easy, given how hard it can be to disentangle their coats in the first place. The logistics of assembling the tens of thousands of sheep necessary to factorise RSA-2048 numbers is left as an open problem

The important part where this scheme came from:

According to Tex Texin, the first numeronym of this kind was “S12n”, the electronic mail account name given to Digital Equipment Corporation (DEC) employee Jan Scherpenhuizen by a system administrator because his surname was too long to be an account name. The use of such numeronyms became part of DEC corporate culture.[3]

So it was a technical limitation gotten corporate naming scheme.

Are there any infos about what an attacker can do with this? The article didn’t say this. Remote Code execution? With the privileges of the app? Reading all files? Or only some? The impact information seems important here.
