Anna Sorokin now faces up to 15 years in prison.
A woman was found guilty of stealing more than $200,000 from banks and friends while posing as a German heiress and scamming her way into NY society, the Manhattan District Attorney said.
Using the name Anna Delvey, Sorokin deceived friends and financial institutions into believing she had a fortune of about $67 million (60 million euros) overseas that would cover her high-end clothing, luxury hotel stays and trans-Atlantic travel. She is scheduled to be sentenced May 9.
Sorokin went to remarkable lengths to have others pay her way, including Rachel Williams, a former Vanity Fair photo editor, who penned a piece about her experience.
"As proven at trial, Anna Sorokin committed real white-collar felonies over the course of her lengthy masquerade", Vance said in a statement. Sorokin, who claimed to be a German heiress, is on trial on grand larceny and theft of services charges.
Authorities said she claimed to be a German heiress in November 2016 to secure a $US22 million loan from a NY bank to open a private club and used false documents to prove she had multimillion-dollar accounts overseas. She was denied the loan but persuaded one bank to lend her $100,000 she failed to repay.
Her attorney, Todd Spodek, insisted Sorokin planned to settle her six-figure debts and was merely "buying time".
During her trial, the court heard competing about the fake German heiress, who was portrayed as a profligate con artist and as an ambitious entrepreneur seduced by New York's opulence.
He said that Sorokin was "upset, as anyone would be", following the verdict, but said she was pleased she had been acquitted of attempting to steal more than $1 million from City National Bank.
"There's a little bit of Anna in all of us", Mr Spodek said.
The verdict followed two days of often tedious deliberations, in which jurors asked for repeated clarification on the law and, in one note to the judge, indicated they had reached a "stalemate" due to a single uncompromising juror.
The case captivated some of New York City's wealthiest residents, and she became known as the "SoHo Grifter".
