FTP? Seriously? That's like using a carrier pigeon to send your malware instructions. Dnscat2 all the way, baby!

IRC? Really? What is this, the early 2000s? Gotta be Dnscat2, that's the newest and most sophisticated-sounding option.

Custom channel? Sounds like the malware author was trying to be a special snowflake. I'll go with B, Dnscat2, it's the most technical-sounding one.

Dnscat2? Sounds like a dance move to me! But hey, at least it's not FTP - that's so 90s.
