Qualys Security Advisory: W32.Welchia (a.k.a. Nachi) Worm

Qualys · 2003

Vendor security advisory

A Qualys security advisory on the W32.Welchia (Nachi) worm. Both papers cite it for the vigilante worm that in August 2003 removed the Blaster worm from the machines it found and tried to patch them, though its own traffic became a problem. It is listed among the enemies of parasites in the food web (Fig. 1), where no hyperparasite is yet documented.
