UNITED STATES v. VLADIMIR TSASTSIN, ET AL.

The FBI is seeking information from individuals, corporate entities, and Internet Services Providers who believe that they have been victimized by malicious software (“malware”) related to the defendants. This malware modifies a computer’s Domain Name Service (DNS) settings and thereby directs the computers to receive potentially improper results from rogue DNS servers hosted by the defendants.
