Lookout Warning Issued for Site Defacements

The Internet Security Systems’ X-Force unit has sounded an alarm for an
increase in hacker activity between July 6-7 to coincide with a contest
encouraging defacements of Web sites around the world.

ISS raised its current threat level to ‘AlertCon 2’ to coincide with the
site defacement competition, which awards prizes to intruders who
successfully compromise an organization’s Web server and deface its Web
pages.

Analysts monitoring the so-called hacking challenge warned that it could
disrupt normal Internet activity and cause mass defacements and shutdown of
affected Web pages.

The group said intelligence showed hacker groups are conducting
“reconnaissance-scans” prior to the “contest” to identify vulnerable
systems. “Major activity won’t publicly surface until the early hours of
July 6, 2003,” X-Force said, encouraging enterprises to review existing
security policies, especially on outward facing Web servers.

The competition in question appears to be targeting HP-UX, Apple and
IBM-AIX systems, which have limited exposure as Web-hosting platforms.

The New York State Office of Cyber Security and Critical Infrastructure
Coordination (CSCIC) also issued an advisory
in anticipation of the attacks and recommended that certain preventative
measures are taken to protect vulnerable systems.

The CSCIC recommendations include:
