This advisory is intended to inform recipients that the FBI has observed an
increase in Hacker activity specifically targeting U.S. systems associated
with e-commerce and other internet-hosted sites. The majority of the
intrusions have occurred on Microsoft Windows NT systems, although Unix
based operating systems have been victimized as well.

gain unauthorized access and download propriety information. Although these
vulnerabilities are not new, this recent activity warrants additional
attention by system administrators.
