Worm.ExploreZip.C was discovered in December, 1999. This worm is a variant of Worm.ExploreZip, which was discovered in Israel, on Jun 6, 1999. The difference is that Worm.ExploreZip.C has been packed by file compression and its message area was translated by patching the original Worm.ExploreZip binary code, which still allows the worm to be executed normally and does not require any manual uncompressing. Because of the compression, the file size is smaller than the original Worm.ExploreZip (104,448 bytes).
