Defendant admits to helping convert stolen crypto into cash for a syndicate that stole 4,100 BTC through large-scale social engineering attacks
A federal investigation into a massive crypto-related social engineering operation has advanced as a 22-year-old California resident pleaded guilty to laundering millions for a syndicate that stole more than $263 million in digital assets. The case highlights the scale and sophistication of modern crypto-targeted criminal networks.
The U.S. Justice Department confirmed that Evan Tangeman admitted to participating in a RICO conspiracy, acknowledging that he laundered more than $3.5 million for the organization. His plea makes him the ninth defendant to admit guilt in the ongoing investigation.
The scheme operated between October 2023 and May 2025, growing from a small group on gaming platforms into a coordinated multi-state syndicate spanning California, Connecticut, New York, Florida, and overseas contacts. According to investigators, the group stole approximately 4,100 BTC, worth $263 million at the time and valued at $371 million today.
Members of the syndicate were divided into hackers, organizers, target identifiers, callers, and burglars who broke into residences to steal hardware wallets. The group used hacked databases and breached servers to identify wealthy crypto holders. Callers then posed as security personnel, falsely claiming victims’ accounts were under attack to extract access information.
The stolen crypto financed luxury spending, including handbags, cars, private jet rentals, security teams, and upscale properties. Tangeman’s role involved using a bulk-cash converter to turn stolen cryptocurrency into cash, then securing rental homes under fake identities to hide the syndicate’s operations.
Tangeman is scheduled for sentencing on April 24, 2026. Following his plea, the court unsealed a second superseding indictment, adding charges against three additional suspects: Nicholas Dellecave, Mustafa Ibrahim, and Danish Zulfiqar.
The case reflects a broader trend of increasingly elaborate crypto-related criminal schemes and heightened federal scrutiny of digital asset crimes.
