The fund, Elliott, is opposing a takeover deal between Samsung companies that critics say will ensure Samsung's founding family retains outsized influence over the conglomerate.
One of the companies, Samsung C&T, posted cartoons online that depicted Elliott's founder Paul Singer as a vulture-like figure.
Last week, Jewish organizations asked Samsung and South Korea's government to denounce anti-Semitic stereotypes in local media.
A business news website withdrew a column in which it called Elliott "Jewish money" and "ruthless and merciless."
