Eisenberg's Defamation Claims Against Barak, Shanons Resolved by Arbitration

A NIS 10 million defamation lawsuit filed by former Prime Minister Ehud Barak and former Unit 8200 commander Ehud Shanons against venture capitalist Michael Eisenberg has concluded through arbitration. The arbitrator, Adv. Meir Mizrahi, ruled that Eisenberg's claims lacked a factual basis. Eisenberg had accused Barak and Shanons, founders of the offensive cyber company Team8, of harming Israel's security when they sold Team8 to an American fund in 2024. However, the arbitrator also determined that Eisenberg's publication stemmed from genuine concern for national security, not malicious intent.

As part of the resolution, Eisenberg was recommended to make a significant donation to the Rehabilitation Medicine Department at Sheba Medical Center, supporting IDF soldiers injured in the war. The dispute began in February 2025 when Eisenberg posted on X (formerly Twitter), sharing severe allegations against Team8 and its founders following the company's sale to an American fund for approximately $900 million. The post amplified claims from an anonymous X account alleging that Team8, Barak, and Shanons compromised Israeli security by recruiting top engineers from Unit 8200, termed "talent theft," and that the sale involved transferring Israeli knowledge without proper regulatory approval.

Barak and Shanons argued in their lawsuit that these were false and grave accusations against two senior former security officials. They demanded Eisenberg remove the publication, issue a public apology in Hebrew and English, and refrain from similar publications. They also requested a NIS 10 million donation to the "My Wave" organization instead of financial compensation.

Eisenberg, in his defense, called the suit a "baseless silencing lawsuit" intended to prevent public discussion of problematic conduct. He claimed that the offensive cyber capabilities of Israel were being commercially exploited, causing significant damage to its reputation. He asserted that his views were shared by others, including three senior intelligence officials who had warned the Ministry of Defense in July 2024 about the risks of selling Team8 to foreign entities.

The case was initially mediated, with Adv. Mizrahi eventually authorized by both parties to act as an arbitrator. Mizrahi's decision noted that Team8 was sold to its current shareholders without a statutory need for Ministry of Defense approval, though the deal was reported in advance and a detailed arrangement was made with security officials to protect Israeli defense knowledge. The arbitrator was convinced Eisenberg acted out of "genuine concern" and did not intend to make definitive factual findings, but rather to raise questions. Mizrahi concluded, "Given the clarifications, I rule that there was no basis for the published statements." He added that Eisenberg would not have published them had he received these clarifications beforehand. The arbitrator also stated that Eisenberg does not doubt Barak and Shanons' contributions to national security and urged both sides to move past the dispute, recognizing the importance of free and respectful public discourse.
