\textbf{Similar Tools}. Several formal methods tools reason about attackers on secure protocols, primarily in the cryptographic context: ProVerif, VerifPal, Tamarin, and Scyther are \textit{Symbolic} and abstract away cryptographic primitives as terms \cite{Kobeissi_Nicolas_Tiwari, Proverif, Tamarin, Cremers}, while CryptoVerif and EasyCrypt are \textit{computational} and reason about game-based cryptographic security proofs \cite{Blanchet_Jacomme, Pereira}. For a general overview, see \cite{ParnoSOK, Basin_Cremers_Meadows_2018}. Before \korg, model checker-based approaches for reasoning about secure protocols have typically employed \spin or TLA+ and only reasoned about correctness \cite{Khan_Mukund_Suresh_2005, Clarke_Wang, wayne_adversaries, Narayana_Chen_Zhao_Chen_Fu_Zhou_2006, Delzanno_Tatarek_Traverso_2014}. 

\textbf{Reasoning About Channels}. There is a long history of using formal methods tools ad-hoc to reason about on-channel attackers, particularly in the context of Byzantine protocols \cite{Wilcox_Woos_Panchekha_Tatlock_Wang_Ernst_Anderson, Castro_Liskov_2002, Delzanno_Tatarek_Traverso_2014}. Formal methods tools have also been applied to reason about message tampering \cite{Henda}, delays \cite{Ginesin}, and congestion control \cite{TCPwn}.
