64. (p. 191) This description is vague, which is in fact one of the problems in anonymization research. What Narayanan and Shmatikov show is that for any reasonable
definition of privacy, reidentification is possible (Arvind Narayanan and Vitaly Shmatikov, "Deanonymizing Social Networks," Proceedings of the 2009 IEEE Computer Society
Symposium on Research in Security and Privacy (Piscataway, NJ: IEEE, 2009), 173-187).

98. (p. 194) The use of exigent letters grew out of experience in the New York field
office. One telephone company analyst who worked with them there briefed the
CAU, which adopted them without question. Analysts from the other companies
were pressed to accept them (U.S. Department of Justice, Office of the Inspector
General, Oversight and Review Division, Federal Bureau o fInvestigation's Use of Exigent
Letters, 40-42).

A striking one occurred with New York's Citicorp Center. A year after the tower was
built in 1977, it was discovered to be at risk of collapse if strong hurricane winds
came at a 45-degree angle. It was retrofitted with steel plates, which corrected the
problem (Joseph Morgenstern, "The Fifty-Nine Story Crisis," New Yorker, May 29,
1995, 45-53).

111. (p. 197) The first problem in the architecture was that the system error messages
stated whether the request had an incorrect username or an incorrect password. This
simplifies finding a valid username. The second problem was with implementations.
The system was designed to compare the hash of the interception request with the
hash of the expected response, and the protocol called for message digests shorter
than 12 bytes to be discarded. Many implementations did not do that, allowing a
small brute-force attack to find an appropriate credential (Cross, "Exploiting Lawful
Intercept," 4-6).

114. (p. 197) The Chinese-manufactured smartcard readers were discovered before
the damage was devastating, and the consequences of the fake Cisco routers was
minor. The equipment did not have secret back doors (John Markoff, "F.B.I. Says
the Military Had Bogus Computer Gear," New York Times, May 9, 2008), and the
counterfeiting appeared to have been done solely for profit. Genuine routers cost
$1,300, while the fakes sold for a little under a fifth of that. (These are low-end
routers; high-end Cisco routers designed to work in the Internet backbone run to
millions of dollars.) There was a real market for the fakes, which came into the
United States through a variety of suppliers.
