Israeli security company Blue Security’s websites have been bombarded by denial-of-service (DoS) attacks for a number of days from spammers, angry over a recent anti-spam tool the company has brought to market, reports.

The article states that the Blue Frog tool, available to members of Blue Security’s “Do Not Intrude” registry, traces and floods senders of unwanted e-mail with opt-out messages, a technique that is likened to fighting fire with fire.

Since the tool has been in use, members of the registry have received threatening e-mails from the spamming community warning them to quit the service, reports. Shortly thereafter, a large-scale distributed DoS attack was started.

Blue Security said that it was being flooded with up to 10 million packets a second at some points during the attack.
