(HedgeCo.Net) — The Securities and Exchange Commission today announced it has obtained an emergency court order to freeze the assets of a United Kingdom resident charged with intruding into the online brokerage accounts of U.S. investors to make unauthorized stock trades that allowed him to profit on trades in his own account.

In a complaint filed in U.S. District Court in the Southern District of New York, the SEC alleges that in April and May, Idris Dayo Mustapha hacked into numerous accounts of U.S. customers of broker-dealers in and outside the U.S. The complaint alleges that Mustapha placed stock trades without the customers’ knowledge and then traded in the same stocks through his own brokerage account. In one case, Mustapha allegedly hacked into a brokerage account and rapidly purchased shares at increasing prices and then profited by selling his own shares of the stock in his brokerage account. According to the complaint, Mustapha’s scheme made at least $68,000 profits for himself and caused losses in the victims’ accounts of at least $289,000.

“We will swiftly track down hackers who prey on investors as we allege Mustapha did, no matter where they are operating from and no matter how sophisticated their technology,” said Robert Cohen, Co-Chief of the SEC Enforcement Division’s Market Abuse Unit.

The SEC obtained an emergency court order today that freezes more than $100,000 in Mustapha’s assets and prohibits Mustapha from destroying evidence.

The SEC alleges that Mustapha violated the antifraud provisions of federal securities laws and a related SEC antifraud rule. In addition to the emergency relief, the SEC is seeking permanent injunctions, return of allegedly ill-gotten gains with interest, and financial penalties.
