Ofer Aiberg is an investigative journalist at Haaretz, one of Israel's leading newspapers, where he focuses on extremism, security issues, and international funding networks supporting controversial groups. His reporting often examines financial flows from overseas donors, particularly in the United States, to Israeli right-wing organizations, settler groups, and entities involved in anti-Palestinian activism. Aiberg's work has highlighted connections between donors like Robert J. Shillman and platforms such as Canary Mission, contributing to exposés on influence networks in Israeli society and politics. Through meticulous investigations based on public records, leaks, and financial disclosures, Aiberg has become a key voice in documenting the interplay between global philanthropy and Israeli extremism. His articles, published primarily in Hebrew, have drawn attention for their depth and have been cited in discussions on foreign influence in Israel's internal conflicts.
