Michael Ron David Kadar, a dual Israeli-American citizen previously known as the “Ashkelon Hacker,” appeared in an Orlando federal courtroom this week to face sentencing proceedings for a massive wave of bomb threats that paralyzed communities across the United States in 2017. Prosecutors are seeking a significant prison term for the defendant, who was convicted of orchestrating thousands of hoax threats against Jewish community centers, schools, and airlines, according to the U.S. Department of Justice.
The Charges and Legal Context
Kadar, who was a teenager at the time of the offenses, pleaded guilty to multiple counts, including hate crimes, communicating bomb threats, and cyberstalking. According to court filings from the U.S. Attorney’s Office for the Middle District of Florida, Kadar utilized sophisticated technology to mask his location and voice, allowing him to issue more than 2,000 threats against institutions in the U.S., Canada, the U.K., and Australia.
The threats specifically targeted Jewish Community Centers (JCCs), causing widespread evacuations and significant financial disruption. Federal prosecutors have emphasized the “terrorizing” nature of these actions, which led to the deployment of emergency services across multiple states.
Why the Case Matters
The sentencing of Kadar serves as a landmark case for international cybercrime jurisdiction. Because the defendant operated from Israel while targeting victims in the United States, the case required extensive cooperation between the FBI and the Israel Police.
Legal experts point to this case as a precedent for how the U.S. government handles extraterritorial digital crimes. Unlike traditional cyber-fraud cases, the Department of Justice pursued these actions as hate crimes, arguing that the deliberate targeting of Jewish institutions was intended to intimidate a specific religious community.
How the Sentencing Process Works
While Kadar was initially sentenced to 10 years in prison by an Israeli court in 2018 for his crimes, the U.S. proceedings represent a separate legal track. In the United States, federal sentencing guidelines allow for up to 35 years for the charges to which he pleaded guilty.
The current proceedings in Orlando are focused on determining the final federal term, taking into account the impact on the victims and the scale of the disruption. Defense attorneys have previously argued that Kadar’s medical condition, specifically a brain tumor and autism spectrum disorder, should be considered as mitigating factors in his sentencing.
Key Facts About the Case

- Defendant: Michael Ron David Kadar, a dual citizen of Israel and the U.S.
- Primary Charges: Hate crimes, cyberstalking, and making bomb threats.
- Scope of Offense: Over 2,000 bomb threats made to schools, JCCs, and airlines globally.
- Jurisdiction: The case is being handled by the U.S. District Court for the Middle District of Florida.
What Comes Next
The court is expected to finalize the sentencing after hearing victim impact statements and reviewing the arguments regarding Kadar’s mental health. Once the U.S. sentence is handed down, it will likely be served in conjunction with or following his existing Israeli prison term. The outcome will be closely watched by cybersecurity analysts and legal professionals as a test of how international law enforcement can effectively prosecute individuals who use the anonymity of the internet to commit violent threats across borders.
