GazTransitStroy/GazTranZitStroy: From Scareware to Zeus Crimeware and Client-Side Exploits


Remember 2009's GazTransitStroy/GazTranZitStroy LLC, AS29371?

The fake Russian gas company whose motto was "In gaz we trust"? It appears that in order to stay competitive within the cybercrime ecosystem, they are now diversifying their offerings from hosting scareware domains and redirectors, to active Zeus crimeware campaigns, next to client-side exploits serving campaigns used as the infection vector.
From last's week's active Zeus C&Cs:
