SEC Charges Latvian Trader with Hacking into Customers' Accounts

The SEC charged a trader in Latvia for conducting a widespread online account intrusion scheme in which he manipulated the prices of more than 100 NYSE and Nasdaq securities and caused more than $2 million in harm to customers of U.S. brokerage firms.  The SEC also instituted related administrative proceedings today against four electronic trading firms and eight executives charged with enabling the trader’s scheme by allowing him anonymous and unfiltered access to the U.S. markets.

According to the SEC’s complaint filed in federal court in San Francisco, Igors Nagaicevs broke into online brokerage accounts of customers at large U.S. broker-dealers and drove stock prices up or down by making unauthorized purchases or sales in the hijacked accounts. This occurred on more than 150 occasions over the course of 14 months. Nagaicevs – using the direct, anonymous market access provided to him by various unregistered firms – traded those same securities at artificial prices and reaped more than $850,000 in illegal profits.

According to the SEC’s orders instituting administrative proceedings against the four electronic trading firms, they allowed Nagaicevs to trade through their electronic platforms without first registering as brokers. Each of the trading firms provided him online access to trade directly in the U.S. markets through an account held in the firm’s name. These firms gave Nagaicevs a gateway to the U.S. securities markets while circumventing the protections of the federal securities laws, including requirements for brokers to maintain and follow adequate procedures to gather information about customers and their trading.

One firm and two individuals each agreed to settle the charges.
