For those like me who interpreted the title to mean that CBS/Showtime had deliberately inserted the crypto-mining code themselves and been caught red-handed doing it: nobody knows who actually did it. The author hypothesizes that it was some malicious actor who got access to Showtime's code base, although this hypothesis is based on the author's surmising that it would be extremely unlikely for CBS to do this deliberately.
