Main Information

Mihail Fortis is an alias/sock puppet name for an Estonian B2B marketer who spams on behalf of himself and small business customers, primarily in Estonia and Finland. Spam is targeted to Estonian and Finnish email addresses, with ignificant spam activity also in Latvia, Lithuania, and the Scandinavian peninsula. Fortis manages to send a great deal of unsolicited bulk email to our spamtraps for an organization that spams primarily in languages spoken by only a few million people.

This spammer has operated under several business names, most recently Logpartner OÜ. The pattern appears to be to register a new business name every six months or so, allowing the previous business to go bankrupt with unpaid bills and tax delinquencies. Previous business names have included Line Transport OÜ, Arendame OÜ, and Saiake OÜ.

The domain remains appears to be Fortis's main business domain. Fortis also either owns or effectively controls a number of .EE domains for various businesses, many of them offering business or personal training. For sending spam, throwaway domains are registered and changed frequently, usually in whichever TLD is cheapest at that time. In late 2017 the preferred TLD is .XYZ, and most domains are registered with Russian Registrar, using Whois Privacy.

Fortis uses a variety of names and contact information to sign up for IP space, most recently Алексей Георгиевич Мокров (Alexey Georgievich Mokrov) <>. As of 2017 Fortis favors Russian VPS providers, but can appear on any VPS provider which provides cheap VPS service with automated provisioning that has inadequate security checks in place.

Fortis usually pays for VPS servers using the Russia-based Webmoney service (, often called Russia's Paypal.

Fortis uses a large number of names to register the domains that he spams from. Originally he used "Mihail Fortis" for domain registrations. Later he used several other other names, some aliases and some belonging to actual persons that register domains on his behalf. As of about a year ago, Fortis started registering domains with Whois Privacy services, especially

Most Fortis spam is sent under a personal name rather than a business name, although certain "fronts" used to register domains recently have had businesses associated with them.

In the past Fortis nameservers as shown in Whois records for were often stale or did not exist, and IP ranges that sent spam did not have rDNS. In January 2016 Fortis changed some of its methods, probably because email from their IPs and domains was widely blocked. At that time, IPs and domains usually had proper configuration for sending email. More recently, Fortis has returned to sending from IP addresses with no rDNS.

The name "Mihail Fortis" shares a postal address with one "Alexei Petrov" (a Russian name), sometimes known of as "Aleksejs Burovs" (the Latvian equivalent). We are not certain whether Petrov/Burovs is an alternate identity or a different person. The name "Mihail Fortis" has also been associated with at least two business names found in the Estonian Business Registry: Euro Marketing OÜ and Scanman Grupp OÜ. Both of these businesses had poor or no reputations, as have other Fortis-associated businesses, but we have found no direct link between them and his spamming activities.

Fortis normally uses hosting in Russia, although it has been known to use hosting in Latvia, Byleorussia, Germany, the Czech Republic, and Sweden as well. It sometimes abuses free redirectors (among them,, and to mask the links in his spam URIs. It seems to go back and forth between spamming very dirty lists and attempting to listwash so that it doesn't hit as many spamtraps.

What Spamhaus has not seen is any indication that Fortis has ever attempted to gain permission from the recipients of its bulk email.
