Clueless filters by sender domain

Virus filters for the following domains have sent us bogus virus warning spam. As you can see, the problem gets worse. In March I sometimes went for a week without a bogus warning. Now I get warning spam almost every day, often even multiple warnings per day. We notify postmasters of all servers sending us virus warning spam. Though we have not received a reply from most of them, neither have we received more spams. Only the few entries listed in bold are repeat offenders, i.e. servers that have sent one or more virus warning spams after their postmaster had already been notified of the problem. Postmasters who do reply generally do so to notify us that they have fixed the problem.

Clueless filters by product

Here are some of the clueless notifications we have received over the course of the last two months. We received multiple examples by all listed filters, these are only examples:

ANTIGEN_IRIS

This one is nicely cryptic:

sent from myaddress and was discovered in IMC
Queues\Inbound
located at Imagen/NEPTUNE1/IRIS.

AMaViS - amavis-milter

This one at least provides the original message headers, allowing the recipient of the "warning" to notify the abuse department of the provider of the real sender:

Webshield

Webshield by Networks Associates "returns" the mail with an advertisement for the filter, including a link to their website: Unsolicited commercial bulk email = spam. What they don't provid is header information. It is likely though that the final Received-line of the virus warning spam indicates the virus sender.

F-Secure

Informationsverbund Bonn-Berlin (IVBB)
Your tax-euro at work: The German Federal government spent a fortune on a secure network for its ministries in Berlin and in Bonn, which nevertheless experienced serious problems coping with a flood of viruses in May. This custom written software of the Federal government insists on sending email to faked sender whenever a virus is received.

Here's another example of a "warning" from a braindead virus scanner that is smart enough to recognize Netsky-emails, but too dumb to understand that all Netsky sender addresses are picked at random from email addresses found on the computer.

Sample replies to clueless virus notifications

Subject: Badly configured virus scanner at yourdomain

Hello,

please reconfigure your virus filter so that it will not spam people whose addresses are listed in From-lines of Netsky, Sober, SomeFool, Swen and other current worm mails. None of the worms released over the last three years uses the sender's actual email address.

It is a well documented fact that these worms mail themselves to intended victims using fake sender addresses, i.e. addresses of innocent third parties found on an infected PC. Notifying the fake sender address is pointless and annoying.

The right address to contact is the abuse-address of the provider from whose network the virus originates (typically, the last Received-line in the header). Unfortunately, your notification does not include Received-lines. Therefore, it's completely pointless.

Regards

Joe Wein

"Clueless virus filters spam innocent third parties

Sample replies to clueless virus notifications (in German)

Hallo,

Ihr Virenfilter ist so fehlkonfiguriert, dass er fuer jeden eintreffenden Virus eine Spam-Email an einen unbeteiligten Dritten verschickt.

Der Virus Netsky, der Ausloeser fuer die untenstehende Mail war, setzt zufaellig ausgewaehlte Adressen, die er auf dem infizierten Rechner gefunden hat (z.B. im Adressbuch des Emailprogramms oder im Browsercache) als gefaelschte Absender fuer seine Virenmails ein. Eine Benachrichtigung an diese Adresse erreicht somit nur unbeteiligte, unschuldige Dritte die mit der Versendung des Virus nichts zu tun hatten.

Der tatsaechliche Versender laesst sich nur ueber die Received-Zeilen im Mailheader feststellen, da daraus der zustaendige Provider des Versenders bestimmt werden kann. Diese Informationen liefert aber Ihre Benachrichtigung nicht mit. Es bleibt also nur eine sinnlose Belaestigung.

Bitte stellen Sie diese automatisierten Email-Spams umgehend ab.

MfG

Joe Wein
