What to do if they ignore you

Hello, My company provides outsource security management/monitoring services. In early March we noticed that several of our clients that are in the same /16 block were getting persistent port 445 probes from a couple of systems from a very large corporation's satellite office which is on the same /16 block. I have repeatedly called the companies security manager (on the US east coast) and talked to people at the companies headquarters (on the US west coast). They take my information (I have shown them firewall logs, IDS logs, captured packet traces, and honeypot sessions) but nothing is done about these probes (typically around 1500/day). We have black-holed connections from the offending network block, but many of our clients are small and do not have firewalls with the resources to handle huge lists of blacklisted networks. It has been over a month now, and nothing has changed. They seem to be unable or unwilling to fix their own systems when they have all the information they could ask for in order to track the problem down. Does anybody have any suggestions on what to do to make Goliath behave when you are David ? -- Dr. Everett (Skip) Carter Phone: 831-641-0645 FAX: 831-641-0647 Taygeta Network Security Services email: skip () taygeta net 1340 Munras Ave., Suite 314 WWW: http://www.taygeta.net/ Monterey, CA. 93940
