More to the point, there actually is evidence of a connection to the Israeli government, inasmuch as "Candiru" was financed by the same people behind NSO, "Founders Group", and both of these entities have very clear ties to Mossad:

"TheMarker Claims that NSO is also a customer of Candiru as it is often seen contacting the surreptitious firm for some espionage-related projects. Two industry sources said the main Candiru financial backer was Founders Group, cofounded by one of the three men who set up NSO, Omri Lavie."

And then, there is its Board of Directors:

"As surveillance industry sources also told Forbes, one of the lead investors is Founders Group managing partner Isaac Zack. According to Pitchbook, Zack is also a board member at wireless charging startup Humavox and at Sepio Systems. The latter is a cybersecurity company, focused on doing the exact opposite of Candiru: protecting hardware from being turned into silent surveillance devices. Its board also includes Tamir Pardo, the former head of the Mossad, Israel’s intelligence agency."
