Cyber Threat Actor: Dr. Amitabh Saxena

Dr. Amitabh Saxena is an alias used by an individual known to be based in India who came to public attention in April 2018 in connection with a security incident involving the Indian cryptocurrency exchange Coinsecure. At the time he was identified as the exchange’s Chief Strategy Officer. The incident involved the disappearance of 438 bitcoins from the exchange’s primary wallet, valued at roughly $3.3 million. The exchange’s chief executive stated that only himself and the Chief Strategy Officer possessed the private keys needed to access that wallet. This statement directly linked Dr. Amitabh Saxena to the loss of the funds. The officer denied responsibility, asserting that the bitcoins had been taken by an external attacker. In response, the exchange filed a police complaint and requested that authorities seize his passport due to concerns about flight risk. The complaint also urged a full investigation to determine accountability for the missing assets.

The case illustrates a targeting focus on the cryptocurrency exchange sector within India, with the apparent objective being financial gain through the illicit transfer of digital assets. No evidence of espionage, disruption, or ideological motives has been presented in the public record regarding this actor. Regarding tactics, the only disclosed detail is the alleged misuse of private‑key access that would constitute an insider threat, while the officer’s claim of an external attack was not substantiated with technical indicators such as malware families, specific initial‑access vectors, or tooling. Consequently, no specific malware, exploit kits, or command‑and‑control infrastructure can be attributed to this actor from the available sources. Attribution to any state‑sponsored group or criminal consortium has not been established publicly. The Coinsecure incident remains the sole publicly reported operation linked to Dr. Amitabh Saxena. As a result, the profile is limited to the facts surrounding that single event.
