Most abused domain registrars in BOTNETS, Q2 2020
When setting up a botnet C&C infrastructure, threat actors need to decide who they are going to register their domain with. Registrars can’t easily detect fraudulent sign-ups; however, domains used for botnet C&Cs don’t tend to have a long lifespan with well-run registrars.
Namecheap The US-based domain registrar Namecheap has been in the #1 spot for a significant length of time.
Enom Entering the Top 20 at #2, Enom had 419 botnet C&Cs operating on domains registered to it in Q2.
