[mod.telecom] HBO Hack

WMartin@SIMTEL20.ARPA.UUCP (05/07/86)

To answer my own question that was included in Telecom #117:

This has been thrashed out pretty thoroughly on the Videotech list by now
(I had sent my query to both Telecom and Videotech). It appears that the
descramblers will automatically go to pass-through mode when an
unscrambled signal appears at its input, and that the pirate's signal
overrode the HBO uplink signal until they boosted their normally low
power to override him. The pirate signal, being in the clear, just
turned off the descramblers for the period of time it was being
relayed by the satellite.
