DAMAGE: None

Critical Facts about Internet Activity
CIAC has been receiving numerous inquiries about reports of apparent
intrusion attempts originating from Milano, Italy. Information
currently available suggests that there has been an increase in
activity on the Internet originating from Milano. The problem,
however, does not appear to be due to network intruders. A computer
security researcher at the State University of Milano, Italy has been
testing a program to check for known bugs. His test has produced
numerous symptoms normally associated with cracker attacks, and has
alerted many system managers throughout the Internet community. This
activity has now ceased, and there does not appear to be any potential
for damage as a result of this test. The researcher who conducted this
test has contacted the system managers whose systems were probed by
this program.
NOTE: This program tests for vulnerabilities exploited by the 1988
Internet Worm, commonly known as the Morris Worm. This program is
still available from some anonymous ftp sites, and could be used by
anyone to determine whether it is possible to intrude into a UNIX
system. A number of systems tested by this program still had unpatched
bugs in the ftp, tftp, rsh, sendmail and finger utilities. If you are
unsure whether systems at your site could be attacked through these
avenues, please contact CIAC:
