Taro Tsuchiya

I am a final-year Ph.D. candidate at Carnegie Mellon University (CMU) School of Computer Science (SCS). I am fortunate to be advised by Professor Nicolas Christin and affiliated with CyLab (Security and Privacy Institute). I study emerging cybercrime and gray services online and build a continuous, large-scale data collection system. The goal is to use these data to infer how an adversary builds and operate their infrastructure.

The notable examples include

• denial-of-service (SIGMETRICS’25)
• address poisoning (USENIX Security’25)
• market manipulation (CCS’26)
• malicious chatbots (ICWSM’26)
• stolen data (USENIX Security’26)
• fake accounts (WWW’24)
• toxicity (WWW’23).

I am a recipient of the Nakajima Foundation Fellowship and the CyLab Presidential Fellowship for my doctoral studies.

Previously, I was a research assistant at Cyber Civilization Research Center (CCRC) under Dr. David J. Farber in 2021 and was a research visitor at the University of Cambridge, Department of Computer Science and Technology under Professor Alice Hutchings in 2025.

I am maintaining blockchain address poisoning detection system, Toxin Tagger (T-T) (website, X Bot).
