Threats suspect tried hard to hide

THE TEEN hoaxer arrested in the barrage of bomb threats against Jewish community centers used the cryptic currency Bitcoin and a disposable Google Voice line to cover his tracks.

Michael Kaydar, a 19-year-old with dual American and Israeli citizenship, went to great lengths to make himself virtually untraceable as he terrorized JCCs across the country for months, The Daily Beast reported.

The first phone calls he allegedly made back in January quickly traced back to a service called SpoofCard, which allows users to change what people see on their caller ID.

But a subpoena sent to TelTech, the New Jersey company behind the SpoofCard technology, at first appeared to be a dead end, the website reported.

The suspect used Bitcoin to underwrite his devious deeds as well as a disposable Google Voice line set up with an alias.

Bitcoin is a virtual currency not registered to a government or regulated bank that can be easily exchanged for real money. Kaydar reportedly paid for his SpoofCard with Bitcoin and used its voice-changing feature to make himself sound like a woman.

A break finally came when he slipped up by forgetting to route his internet connection through a dummy server, The Daily Beast said.

The teen, who is Jewish, was nabbed Thursday at his home in Ashkelon, a city on Israel’s southern coast, after an international probe spearheaded by the FBI.

Jewish groups celebrated the arrest in the threats, which raised concerns of a rising wave of anti-Semitism.

Israeli police called Kaydar a hacker, but said his motives remain unclear.

Kaydar shielded his face from photographers as guards escorted him out of a courtroom Thursday.

The teen's lawyer said his client suffers from a “very serious” medical condition that kept him out of school and the Israel Defense Forces - and may have affected his behavior.
