Mr. Vance and a team of investigators working under him, including members of the Major Economics Crimes Bureau, uncovered misrepresentations of Newsweek’s finances that included a fictitious accounting firm called Karen Smith L.L.P., prosecutors said. Money ostensibly borrowed for office equipment was used for other purposes, according to the charges.

Journalists at Newsweek, including two top editors and a reporter, were fired in 2018 after they looked into IBT Media’s financial dealings and legal troubles in the weeks after the raid. Several others resigned. The district attorney’s office filed criminal charges against Mr. Uzac and Mr. Anderson in October 2018, accusing them of a multimillion-dollar fraud and money-laundering conspiracy.

The charges also named IBT Media, which bought Newsweek from IAC/InterActive in 2013. IBT Media pleaded guilty on Tuesday and agreed to forfeit $30,000.

In a statement on Friday, Mr. Vance called the crime “a massive fraud scheme through which a group of sophisticated criminals illegally moved tens of millions through our Manhattan marketplace by brazenly overstating the financial health of their companies.”

An attorney for IBT Media and Mr. Uzac, Marc Agnifilo, said in a statement on Friday, “IBT Media is pleased to close this matter and looks forward to continue to grow the business.” He added, “We agreed to a resolution that does not involve jail and allows Mr. Uzac and all defendants the ability to put this chapter behind them.”
