Poor follow-up after a big FBI cyber bust leaves millions of computers vulnerable.

The FBI’s Operation Ghost Click took down an Estonian Internet fraud ring running criminal DNS servers in November. FBI allowed the servers to run for 120 days to give owners of infected computers time to clean out the DNSchanger malware. But the bureau dropped the ball on getting the word out.

Government Computer News reports days before the deadline to take servers down, millions of computers remained infected. Government agencies, though, had largely cleaned their systems. A federal judge has extended the deadline to July 9th.
