Dark Web User Known As “The Bull” Charged In Insider Trading Scheme

For Immediate Release
U.S. Attorney's Office, Southern District of New York
Apostolos Trovias, a/k/a “The Bull,” Used the Dark Web and Encrypted Messaging Services to Solicit, Offer, and Sell Inside Information

Audrey Strauss, the United States Attorney for the Southern District of New York, and William F. Sweeney Jr., Assistant Director-in-Charge of the New York Field Office of the Federal Bureau of Investigation (“FBI”), announced today the unsealing of a criminal indictment and a criminal complaint charging APOSTOLOS TROVIAS, a/k/a “The Bull,” with securities fraud and money laundering in connection with his scheme to solicit and sell stock trading tips and pre-release earnings and deal information regarding public companies.

Manhattan U.S. Attorney Audrey Strauss said: “Today’s charges demonstrate our Office’s continuing commitment to stopping those who pursue and use inside information to gain an illegal edge in the stock market. As alleged, Apostolos Trovias attempted to hide his insider trading scheme behind anonymizing software, screennames, and bitcoin payments. The Indictment and Complaint unsealed today show that committing insider trading using new technologies still produces a decidedly traditional outcome: a criminal indictment.”

FBI Assistant Director William F. Sweeney Jr. said:  “Behind the veil of the Dark Web, using encrypted messaging applications and emails, Trovias created a business model in which he sold—for profit—proprietary information from other companies, stock trading tips, pre-release earnings, and other inside information, as we allege. The FBI operates within the Dark Web too, and as Trovias learned today, we don't stop enforcing the law just because you commit federal crimes from behind a router with your keyboard.”

According to the allegations in the Indictment and Complaint unsealed today in Manhattan federal court:[1]

Since at least in or about December 2016, APOSTOLOS TROVIAS, who identifies himself by the pseudonym “The Bull,” has used websites on the Dark Web and encrypted messaging services to solicit and sell confidential, non-public information about publicly traded companies (“Inside Information”) to enrich himself. TROVIAS’s scheme consisted of multiple related efforts to obtain and monetize confidential nonpublic business information, including (1) the sale of misappropriated stock tips based on confidential customer trading information; (2) the sale of pre-release earnings reports and deal information misappropriated from publicly-traded companies; and (3) the attempted creation of an online marketplace to connect, for a commission, individuals misappropriating Inside Information to individuals willing to pay for and trade on Inside Information.

For example, between in or about December 2016, when he registered for a Dark Web site known as AlphaBay Market, and in or about July 2017, when AlphaBay ceased operations, TROVIAS offered for sale and sold stock tips that were based on non-public inside information about certain securities issuers and which could be purchased individually, or as weekly or monthly subscriptions.

At various times between in or about June 2017 and February 2020, TROVIAS sold Inside Information directly to purchasers, using encrypted messaging and email services to communicate about the sale, rather than exclusively through the marketplace features of the Dark Web forums. For instance, TROVIAS offered for sale and did sell, among other confidential information belonging to various securities issuers, for approximately $5,000 in Bitcoin, at least one pre-release earnings report misappropriated from a publicly-traded company.

In or about 2020, TROVIAS also took steps to design and build a website to facilitate the purchase and sale of material, non-public information for use in stock trading (the “Inside Information Auction Site”). TROVIAS planned to use the Inside Information Auction Site to enrich himself by charging membership fees and commissions from individuals using the Inside Information Auction Site to engage in the unlawful trade of Inside Information.

TROVIAS, 30, of Athens, Greece, is charged with one count of securities fraud and one count of money laundering.  The securities fraud count carries a maximum penalty of 25 years in prison.

The maximum potential sentences in this case are prescribed by Congress and are provided here for informational purposes only, as any sentencing of the defendant will be determined by the judge.

Ms. Strauss praised the outstanding work of the FBI. Ms. Strauss further thanked the U.S. Securities and Exchange Commission, which today filed a parallel civil action, and the Internal Revenue Service for their cooperation and assistance in this investigation.

The prosecution of this case is being overseen by the Office’s Securities and Commodities Fraud Task Force.  Assistant U.S. Attorneys Matthew Podolsky and Andrew Thomas are in charge of the case.

The charges contained in the Indictment and Complaint are merely accusations, and the defendant is presumed innocent unless and until proven guilty.
