“In approximately November 2024, during his investigative work, YAROCH was exposed to adversarial cryptocurrency accounts,” the complaint says. YAROCH claimed he was frustrated that the FBI could not or would not act against adversarial cryptocurrency accounts.” In court Wednesday, prosecutors said Yaroch could be facing additional charges but did not specify what those charges could be. On May 14, 2026, YAROCH traveled from Washington, DC to Germany and did not report it to the FBI, which is a security requirement. On May 25, 2026, YAROCH returned to Washington, DC from Portugal, and did not report it.”
