Netanyahu Aide's Leaked Messages Expose Potential Security Flaw
Translated & summarized from Cursorinfo by baba
Thousands of messages from Yonatan Uriach, an advisor to Israeli Prime Minister Benjamin Netanyahu, have been leaked online, revealing potential security vulnerabilities. The leak, published on a dedicated website, includes communications with political figures and journalists, raising concerns about access to sensitive government data. Uriach's lawyers claim some messages are altered and warn of legal action. The leak may stem from Uriach's use of a third-party messaging service and an AI tool with code posted publicly, though the exact source and extent of the breach are unconfirmed. Uriach faces separate charges related to leaking classified documents and is involved in the "Qatargate" investigation.

Thousands of messages allegedly belonging to Yonatan Uriach, a senior assistant and media advisor to Prime Minister Benjamin Netanyahu, have been leaked online, sparking a scandal in Israel. A website was created on Sunday, October 11, to publish these purported communications with political figures and journalists, with the latest dated September 24. Among those reportedly communicating with Uriach are Netanyahu's assistant Topaz Luk, political commentator Yaakov Bardugo, and Channel 12 journalist Amit Segal. While messages involving the Prime Minister, his wife Sara, and son Yair are mentioned, they have not yet been published.
Uriach's lawyers, Amit Haddad and Noa Milstein, released a statement asserting that some messages have been altered and warning of potential legal action against those involved in the breach and dissemination. The authenticity of the entire cache of messages remains unconfirmed, as does the identity of those responsible for the leak.
The circumstances of the potential leak have drawn significant attention. Calcalist reported that Uriach had connected his personal WhatsApp to UltraMsg, a third-party message management service linked to the UAE. This connection could have granted the service access to messages and media files, posing a risk to confidential information exchanged within the Prime Minister's inner circle.
An additional vulnerability was discovered in an AI-powered tool Uriach developed to monitor publications about Netanyahu and his wife, automatically sending notifications to WhatsApp groups. The project's code was posted on GitHub, a public repository. Calcalist and Haaretz estimate that the leaked files might contain identifiers and access tokens that could allow unauthorized parties to obtain information about group members, including phone numbers, and potentially access conversations. It is also possible to send messages from the connected account using such data.
While other GitHub users reportedly copied the code, it has not been proven that this specific vulnerability caused the leak, nor is the extent of the compromised information known. This scandal unfolds amidst ongoing legal proceedings against Uriach. In June 2026, he was indicted for allegedly leaking classified documents to the German publication Bild, with charges including the transfer of secret intelligence materials from the IDF and obstruction of justice. Uriach is also implicated in the "Qatargate" investigation concerning suspicions of promoting Qatar's interests through Israeli media figures. Despite these legal challenges, Uriach continues to work in Netanyahu's office, as the Central District Court previously rejected a prosecution request to remove him from his position and ban him from government facilities.
