JOHN "CAPTAIN CRUNCH" DRAPER THREE TIME CONVICTED PHONE PHREAK
(FRAUD BY WIRE) DISCOVERED WHAT MAY BE THE ULTIMATE PHONE TAPPING
METHOD.

"I KNEW THE PHONE COMPANY UTILIZED AN AUTOMATIC VERIFICATION IN
MANY AREAS, THIS ALLOWED THE OPERATORS TO GO ACROSS (LISTEN IN)
ON ANY LINE IN THEIR AREA TO SEE IF IT WAS IN USE OR OUT OF
SERVICE.  THERE WAS A SHORT TIME LIMIT WHICH AUTOMATICALLY
DISCONNECTED THE OPERATOR AFTER USING THE PROCEDURE.

SOME YEARS AGO I FIGURED OUT HOW TO ACCESS THE AUTO-VERIFY SYSTEM
WITH A BLUE BOX, BYPASSING THE HUMAN OPERATOR.  THIS WAS POSSIBLE
BECAUSE THE PHONE COMPANY HAD INSTALLED A COMMON VERIFY TRUNK
THROUGH A NUMBER OF LOCAL TOLL CENTERS.

I DISCOVERED I COULD ACCESS THIS TRUNK BY DIALING A SEVEN DIGIT
NUMBER AND THEN A THREE DIGIT ACCESS CODE (WITH THE BLUE
BOX). THIS WOULD CONNECT ME TO ANY PHONE LINE FOR AS LONG AS I
CHOOSE TO STAY ON THE WIRE.  THIS SAME PROCEDURE WAS USED BY
TELCO TO VERIFY FOR CONVERSATION AND "CHECK FOR TROUBLE ON THE
LINE" A EUPHEMISM FOR LISTENING IN ON AN INTERESTING LINE.

THE IMPLICATIONS OF THIS WERE STAGGERING.  I LISTENED TO THE
LOCAL FBI'S PRIVATE LINES, THE LOCAL ATTORNEY GENERAL, THE LOCAL
CIA, AND EVEN PHONE COMPANY SECURITY AGENTS.  AFTER A WHILE THE
AUTO VERIFY SYSTEM WOULD ONLY CONNECT TO EACH LINE FOR A SHORT
WHILE, BUT I COULD OVERRIDE THIS PROBLEM BY SHOVING A 2600 HZ
TONE DOWN THE LINE."

JOHN WAS EVENTUALLY BUSTED BY FBI AGENTS TAPPING HIS PHONE, WHO
WERE WELL, SURPRISED TO HEAR THEIR OWN CONVERSATIONS ON JOHN'S
LINE!  THEY CAME THROUGH THE DOOR AT 2:00 AM ONE MORNING TO HAVE
A LITTLE CHAT WITH JOHN ABOUT HIS UNUSUAL TALENT...

WHAT DID THEY TALK ABOUT ON THEIR "SECURE PRIVATE LINES"?
"MOSTLY THEIR GOLF GAMES AND THEIR WIVES" WAS JOHN'S COMMENT TO A
LOCAL NEWSPAPER.

THE AUTO VERIFY CONCEPT HAS SINCE BEEN PHASED OUT IN MOST AREAS,
BUT THE IDEA OF THE PHONE COMPANY INSTALLING AN AUTOMATIC TAP FOR
ANY LINE IN THEIR SYSTEM, FROM ANY PHONE IN THEIR SYSTEM, IS A
STARTLING ONE INDEED...
