| Unauthorized Computer Access Nears Historical High in Japan
August 18, 1998 (TOKYO) -- Unauthorized access to computer systems in
Japan via the Internet is up almost to previous record levels, according
to the Japan Computer Emergency Response Team Coordination Center (JPCERT/CC).
|A total of 197 attacks on 296 sites were reported to the center during
the three months of this fiscal year (April-June). This figure is close
to the previous quarterly record of 202 cases.
Attacks on common gateway interfaces on Web servers, reported by 113
sites, were the most prevalent type of abuse in the April-June quarter.
Mail bombing was the next highest infringement, affecting 56 sites.
These two types of abuse declined during the previous six months, but
are now on the increase again.
A new method of attack -- by accessing servers and seeking out the weak
points in their security -- was detected at 50 sites.
Other reported incidents included intrusion to computer systems or use
of system administrator accounts, which affected 21 sites. Ten sites
experienced attacks on their DNS server, and attacks on mail servers
disrupted services at a further 10 sites.
The JPCERT/CC has published recommendations for countering these types
of attacks. The recommendations are available in Japanese only on the
center's < A HREF="http://www.jpcert.or.jp/">Web site.
