Known as Operation Sunflower, the fraud ring deployed misleading advertisements featuring prominent Dutch and Belgian personalities to exploit victims. Most victims lost over €10,000 ($16,371) each. The deceitful operation ran for a minimum of four years before it was dismantled in July.
International Arrests and Extradition
Tenenbaum was apprehended on May 26 at a Polish airport upon arrival from Dubai and was later extradited to the Netherlands. Alongside Tenenbaum, five other individuals were arrested in Poland, Cyprus, Greece, and Belgium, with Dutch officials indicating there may be additional arrests.

Tenenbaum’s cybercriminal journey commenced in the late 1990s. In 2001, he confessed to infiltrating systems belonging to the US Air Force, Navy, Pentagon, NASA, Massachusetts Institute of Technology (MIT), and Israel’s Knesset. The FBI’s Solar Sunrise investigation into these incursions even reached the White House, initially raising fears of state-sponsored cyber attacks.

In 2013, Tenenbaum was arrested again in Israel for suspected money laundering, with large amounts of foreign currency being funneled into Israel from known criminals. The resolution of this legal situation remains uncertain.
