In-depth summary:
Avraham Eisenberg, known for exploiting the Mango Markets crypto protocol for a massive nine-figure payday, has been sentenced to 52 months in federal prison. The investigation was primarily driven by journalist Christopher Brunet from Karlstack, who initially exposed Eisenberg’s crypto exploit three years ago.
After being outed for his crypto manipulation, Eisenberg fled to Israel to avoid extradition. Interestingly, he returned to Puerto Rico in December 2022, reportedly to secure tax residency, which led to his arrest by the FBI. During the arrest, authorities discovered a shocking 1,274 items of child sexual abuse material (CSAM) on his electronic devices, including disturbing content described as “a young corpse.”
The article also highlights the mysterious context surrounding Eisenberg, including the suspicious death of his associate Nikolai Mushegian, who had tweeted about potential sex trafficking and blackmail before drowning on Condado Beach. Brunet frames this investigation as a significant personal and journalistic achievement.
