An investigation has linked Israel-based firm Koios to 400 fake social media accounts that spent a year promoting chipmaker NVIDIA, defending CEO Jensen Huang, backing AI chip sales to China and attacking US lawmakers who supported export restrictions.
The accounts also defended Huang amid reports of an alleged affair with a woman suspected of links to Chinese intelligence. Huang has since resigned as CEO and a board member with immediate effect following reports of two affairs.
CFO Colette Kress has been appointed interim CEO. Koios, co-founded by a former Israeli intelligence officer and linked to a Qatar influence campaign involving two Netanyahu advisers, said the project ended in September 2025, but the accounts continued posting.
A new firm, IntellACT, has since emerged. NVIDIA denied any connection.

Unit 8200 is the largest unit in the Israel Defence Forces (IDF) and serves as the country’s primary signals intelligence (SIGINT), code decryption, and cyber-warfare agency. Often compared to the United States’ National Security Agency (NSA), it handles cyber warfare, electronic eavesdropping, code-breaking, and military intelligence. Founded in 1952, it operates out of Tel Aviv and major installations like the Urim SIGINT Base in the Negev desert. It is currently led by Brigadier General Yossi Sariel. Many veterans of the unit go on to found or lead major global cybersecurity and tech enterprises (such as Check Point, Wix, and Waze).
