Joe Stewart, director of malware research for SecureWorks counter threat unit research team, and his team dug into the domains shared by these malware families, which appear to have been registered by an individual whose physical address they traced to a P.O. box in the fictional location of "Sin Digoo," California.
The domains were registered under the names of "Tawyna Grilth" and "Eric Charles" with a specific Hotmail address during 2004 and 2011. Malware samples using the Tawyna Grilth domains are tied to advanced persistent threat (APT) activity, according to SecureWorks. But the researchers also found that "Tawnya's" domain hosted a Black Hat search engine optimization service.

"I can't see the same person as a spy by night and an SEO [attacker] by day. But could the two worlds combine?" Stewart says.
Stewart says since the same person registered these domains over the years, he or she could possibly have been freelancing for a nation-state organization or dabbling in Black Hat SEO on the side. But there was indeed a connection.
"He's got domains used for espionage. That's not to say he's the one hacking into those governments and companies. But he seems to have registered those domains," Stewart says. The researchers found that the attacker had also written an attack tool, but they can't prove he's using it or providing it to others.
Just how the cyberespionage and Black Hat SEO activities are related or not is unclear, he says. "We can only speculate from there."
