The 27-year-old who survived the botched explosion of a pipe bomb strapped his chest at New York City's Port Authority in December carefully hedged his plea on Thursday.
Prosecutor George Turner said prosecutors had gathered materials for the case including surveillance videos, photos from the crime scene, DNA evidence, statements that Ullah made to officials after his arrest, postings from his social-media accounts, e-mails, MetroCard data, and phone records.
The 27-year-old stands charged with providing material support to a terrorist organization and other counts in the December 11 attack. "I did it for the Islamic State", he allegedly said.
"As alleged in the indictment Akayed Ullah constructed a pipe bomb and detonated it in a mass transit hub in the heart of New York City to terrorize as many people as possible and to bring ISIS-inspired violence to American soil", said Acting Assistant Attorney General Boente, who announced the federal grand jury's decision.
The suspect, a Bangladeshi man, was in the USA on a chain migration visa, Department of Homeland Security Press Secretary Tyler Houlton said at the time.

Alongside it was a document outlining a "vision" for Trump's border wall: 700 miles, at a cost of $18 billion. However, the parents of Dreamers would be able to obtain a three-year, renewable legal status.
Ullah's public defender, Amy Gallicchio, would not explain the unusual phrasing. U.S. Magistrate Judge Katherine Parker is pictured at left on the bench beside the video monitor.
The Bangladeshi man accused of attempting a suicide bombing in a busy New York City commuter hub in the name of Islamic State in December was indicted on U.S. terrorism charges by a grand jury on Wednesday. He appeared to be the only person seriously injured during the incident.
Emotions ran high at the time of Ullah's arrest, which occurred in the middle of the holiday season and quickly fed the political machine. Ullah posted on Facebook earlier in the day of the attack, "Trump you failed to protect your nation", according to a criminal complaint.
He will be arraigned before Judge Sullivan. He has been housed at the Metropolitan Correctional Facility in Lower Manhattan since he was moved from Bellevue Hospital last month.
