Open SESAME: Fighting Botnets with Seed Reconstructions of Domain Generation Algorithms. (arXiv:2301.05048v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
An important aspect of many botnets is their capability to generate
pseudorandom domain names using Domain Generation Algorithms (DGAs). A cyber
criminal can register such domains to establish periodically changing
rendezvous points with the bots. DGAs make use of seeds to generate sets of
domains. Seeds can easily be changed in order to generate entirely new groups
of domains while using the same underlying algorithm. While this requires very
little manual effort for an adversary, security specialists typically have to …
