We have a similar problem on one of our co-location servers: - centos5 i386 - apache 2.2.3-11.el5.centos (2.2.6 backport) - php 5.2.5 (compiled from source) The issue appears at random.. when it is present, a request to the web server will respond with a redirect to a spyware or malware download site. This will continue to redirect 10% of the traffic to the box until httpd is restarted. The redirection script is not found in any file on the server filesystem and believed to be injected into the response stream via a compromised httpd process in memory. This issue was happening on the same box when It used to be apache 2.0.56, php 5.1.0 running redhat 9. upgrading the distribution, apache, php etc has so far not resolved the issue. At this point we are upgrading to apache 2.2.3-11.el5.centos.3 (2.2.8 backport) in hopes that the recent security patches in this build relating to XSS will solve the issue. I would really like to find the source of the problem, though. -Jeff
Hmmm I wonder if its related to the Javascript hack that people have been seeing at isc.sans.org and other places. http://isc.sans.org/diary.html?date=2008-01-18 -- Stephen J Smoogen. -- CSIRT/Linux System Administrator How far that little candle throws his beams!
