FBI: Man who allegedly sent bomb threats to Jewish community centers sold his services on dark web

A newly released FBI search warrant revealed that 19-year-old Michael Ron David Kadar, who is accused of emailing and calling in bomb threats to multiple Jewish community centers, allegedly used a black-market website to sell his services.

Kadar is accused of making a series of security-related threats and publishing false reports, which incited fear in the Jewish community around the world earlier this year.

According to Israel police spokesman Micky Rosenfeld, Israel, the United States, Australia and New Zealand received "ominous calls at public places, events, synagogues and community buildings," NBC News reported  in March.

Authorities said a search of Kadar's computer revealed that he posted an ad titled,  "School Email Bomb Threat Service" on AlphaBay, a site on the "dark web," NBC News reported. The information was previously sealed because the investigation was ongoing.

"I email bomb threats to schools on your requests. If you feel you need someone to do this job for you then this service is for you," the ad said, according to the FBI affidavit.

Kadar also reportedly said that he could try to frame someone else for the threat but there was "no guarantee that the police will question or arrest the framed person."

Prices for Kadar's services ranged from $30 for an emailed school bomb threat to $90 for multiple schools, according to the FBI.

Attorney General Jeff Sessions ordered AlphaBay shut down in July after discovering the website ran on the dark web and used crypto-currencies, such as bitcoin, to sell illegal items, including drugs and weapons.

Sessions said the investigation is "likely one of the most important criminal investigations of the year," CNN reported.

According to affidavits, it appears that at least one person in California may have utilized the "dark web" services, leading to emailed threats to six administrators at Rancho Cotate High School in Rohnert Park, California, in March, the FBI said, according to NBC News. The threats reportedly claimed bombs had been planted at the school and that the sender of the threat had "assault rifles and Machine pistols."

The next day, Kadar's alleged AlphaBay username had a positive review: "Amazing on time and on target. We got evacuated and got the day cut short," the review reportedly said. 

"While prosecutors have not alleged that any of Kadar's threats were carried out, the federal complaints against him in the U.S. say that the calls and emails prompted evacuations or lockdowns of the targeted facilities," CNN reported.

Kadar, who is Jewish and has dual Israeli-American citizenship, was indicted by Israeli prosecutors and charged by the Department of Justice. It is unclear where he was arrested.

"Authorities have tied him to threats, hoaxes and extortion attempts to more than 2,000 Jewish community centers, schools, airlines, police stations and other institutions spanning more than two years," NBC News reported.

Jewish centers and synagogues in New York, Chicago, St. Louis, Florida, Australia and New Zealand received threats that are believed to be Kadar's doing.

The six-month long investigation revealed Kadar's "advanced camouflage technologies" he utilized when contacting various countries so he couldn't be traced.

In March, Kadar's public defender made it known that his client has had a brain tumor since he was 14, which significantly impacts his cognitive ability, NBC News reported. He has been homeschooled since the diagnosis and cannot work or serve in the Israel Defense Forces, his attorneys said.

According to CNN, Kadar remains in custody in Israel pending his trial. It is unclear what his pending charges are. U.S. authorities are not expected to seek extradition, NBC News reported.
