Win32/Yaha is a family of mass-mailing network worms that targets certain versions of Microsoft Windows. The worm spreads primarily by sending a copy of itself as an attachment to e-mail addresses gathered from an infected computer. It can also spread through mapped drives and writeable network shares. The worm can terminate security-related processes and conduct denial of service (DoS) attacks against certain Web sites.
