Worm.ExploreZip(pack) was discovered on Nov 24, 1999. This worm is a variant of Worm.ExploreZip, which was discovered in Israel, on Jun 6, 1999. The only difference is Worm.ExploreZip(pack) has been packed by file compression, which still allows the worm to be executed normally and does not require any manual uncompressing. Because of the compression, the file size is about 40% smaller than the original Worm.ExploreZip.
