The government moved the proceedings to the big ceremonial courtroom, for this was to be the sentencing of 30-year-old Hector Xavier Monsegur, the biggest informant in the history of cyber crime, the guy the feds say prevented 300 attacks.

But apart from government people and reporters, there were only three spectators when Monsegur trundled his bulky self into the cavernous chamber on the ninth floor of Manhattan federal court late Tuesday morning. And they appeared to be relatives.
Monsegur dubbed himself Sabu in the hacker world, after a wrestler of that name who is purportedly from Saudi Arabia and is in fact a Lebanese American from Detroit. Monsegur has the original Sabuâs size but seemingly little of his physical prowess. He looked like the worldâs largest nerd as he stood before the judge in an outsize black short-sleeved shirt, baggy tan pants, and wire-rim glasses.
âThe United States v. Hector Monsegur,â Judge Loretta Preska said.
The ensuing proceeding sounded more like The United Sates with Hector Monsegur, as the defense attorney, the prosecutor, and the judge filled the empty chamber with hyperbolic descriptions of Monsegurâs cooperation with the government.
âWe have never witnessed a case like this,â defense attorney Peggy Cross-Goldenberg said.
âThrough his cooperation, we averted untold millions of dollars in loss to victims,â Assistant U.S. Attorney James Pastore said. âWe also averted potential really catastrophic problems with critical infrastructure.â
âIt was truly extraordinary,â the judge said. âWe donât often hear of this.â
She added that she was particularly impressed that Monsegur had decided to cooperate almost immediately after his 2011 arrest. And he had not just named names, he had thrown himself completely into helping the FBI build a case against his fellow hackers.
âThe immediacy of Mr. Monsegurâs cooperation and its around-the-clock nature was particularly helpful to the government,â she said. âThat personal characteristic of turning on a dime to doing good, not evil, is the most important factor in this sentencing.â
The judge did not seem to consider that it was the circumstances that turned on a dime and that Monsegur had simply continued to do what he felt was good for Monsegur. She praised him for not only confessing to the crime for which he was accused but to crimes the FBI did not even know he had committed. She was not so cynical as to think that he had done so figuring this was exactly what would impress her and the prosecutors.
âYou have done as much as any human being can do in terms of helping the government to make up for your past wrongs and to avert other damage to probably millions of people,â the judge went on to say. âSo, I salute you for that.â
The courthouse windows to Monsegurâs left looked out in the direction of the Lower East Side and the housing project where he is something of a hero, despite being a snitch. He was raised in the Jacob Riis Houses by his grandmother while his father and his aunt were doing seven-year prison terms for selling heroin. He had dropped out of struggling Washington Irving High School, which is in a hand-me-down building vacated by Stuyvesant High School when that fabled academy for math and engineering whizzes moved to newer and grander quarters.
But he had marked himself as different by not talking street. And he became the stuff of project legend as he taught himself code and programming. That his computer keyboard was missing the L, 7 and Shift keys made it only more miraculous that he could dramatically improve a neighborâs credit rating or order himself more than $3,000 in auto parts without having to pay for them.
Even after it became known he was an informant, his neighbors could not help but be impressed also to hear that he had helped to hack big-time corporations and governments as music blasted all night from behind his door and the smell of pot smoke seeped into the hallway. The guy had been messing with the president of Tunisiaâs website while sitting in a sixth-floor apartment on Avenue D.
The FBI seems to have been no less impressed, though fellow hackers have described Monsegurâs cyber skills as respectable enough but unremarkable. The FBI might have been easy to wow because its own skills appear to be so modest. The FBI only caught Monsegur in the first place as the result of initial investigative work undertaken by two private citizens, a housewife and a man with mild brain damage from a motorcycle accident, who had become disenchanted with the more extreme âhacktivists.â
The FBIâs subsequent criminal complaint describes Monsegur as part of âan elite hacking collectiveâ and having âserved primarily as a ârooter,â analyzing code for vulnerabilities which could be exploited.â
In truth, Monsegur seems to have been less adept at analyzing code than he was at analyzing codersâalong with FBI agents, prosecutors, and ultimately a judgeâfor vulnerabilities that could be exploited. He manipulated a number of hackers into providing information that led to their identification and arrest. And he seems to have persuaded at least one to attempt a crime the future defendant otherwise might not have contemplated.
Among those he cheered on was Jeremy Hammond, listed as the FBIâs most wanted cyber criminal. Hammond was sentenced in the same Manhattan courthouse by the very same judge to 10 years in prison. Monsegur appeared to have urged Hammond to hack the websites of several foreign governments.
âTrust me,â Monsegur said in one cyber chat with Hammond. âEverything I do serves a purpose.â
Monsegurâs immediate purpose was to please the FBI. Skeptics have suggested that the FBI was attempting a kind of two-for in which it built a case against a hacker while gleaning whatever data about the foreign websites the hacker passed on.
âRelax, I am a federal agent,â he told a city cop who asked him for identification outside the projects one night.
In any event, there is no disputing that the FBI recorded all of Monsegurâs cyber communications and activities while he was at liberty as an informant.
âDuring this time the defendant has been closely monitored by the government,â the prosecutor, Pastore, said during a subsequent hearing. âWe have installed software on a computer that tracks his online activity. There is also video surveillance in the defendantâs residence.â
That continued until March 2012, when the FBI arrested Hammond along with four others. The press release revealed Monsegur to be an informant.
Monsegur remained at liberty until that May, when his bail was revoked for postings that the government declines to identify. He was freed after seven months.
At Tuesdayâs sentencing, Monsegurâs attorney suggested that the relatively brief time behind bars was enough considering her clientâs cooperation, which the judge described as âextraordinaryâ a half-dozen times. The judge asked Monsegur if he had anything to say and he rose.
âGood morning, your honor,â he said.
âGood morning, sir,â the judge said.
âI came a long way,â Monsegur said of the time since his arrest. âI had to do a lot of thinking, a lot of soul searching.â
He paused.
âI assure you, you wonât see me in this courtroom again. Iâm not the same person you saw three years ago. Iâm ready to move on.â
Monsegur sat.
âIf there are any victims in the courtroom who would like to be heard,â the judge said.
There was only silence. This was at least not one of those cases where an informant gets a pass on multiple murders. And the government was claiming that Monsegur may have actually saved people, by thwarting some hackers who had figured out a way to contaminate an entire cityâs water supply.
âSeeing none,â the judge said.
The judge noted that during his time in jail, Monsegur had taught computer basics to his fellow prisoners.
âI salute you,â she said. âYou seem to be on the right path.â
She added that Monsegur had no prior criminal record. She also accepted the defense attorneyâs contention that Monsegur had became an informant in the first place for fear that the young cousins who had been left in his charge would be consigned to the horrors of the foster care system. She praised him for his continuing dedication to them.
âThat he was able to continue that high level of devotion when he was under such personal stress is a great tribute to him,â the judge said.
Her sentence came as no surprise.
âTime served.â
She had some advice.
âThe things you did before were not so good,â she said. âYou obviously have great skill. To deploy that skill for good would be a very good thing.â
She was speaking of his cyber skills. But as the big case ended in the big empty courtroom, a question hung in the air.
In the criminal complaint where Monsegur is termed a ârooterâ who specialized in analyzing code for vulnerabilities, another of the hackers is described as specializing in âsocial engineering.â
âThat is, manipulating others into divulging personal information,â the complaint says.
The question is whether it was really Monsegur who was the master social engineer, his genius not in reading code but coders, along with everybody else, including the defense attorney and the prosecutor, who both embraced him at the end, and the manifestly decent and good-hearted judge, who set him free.
