Identify the computer fraud and abuse technique used in each of the following actual examples of computer wrongdoing. a. A teenage gang known as the "414s" broke into the Los Alamos National Laboratory, Sloan-Kettering Cancer Center, and Security Pacific Bank. One gang member appeared in Newsweek with the caption "Beware: Hackers at play." b. Daniel Baas was the systems administrator for a company that did business with Acxiom, who manages customer information for companies. Baas exceeded his authorized access and downloaded a file with 300 encrypted passwords, decrypted the password file, and downloaded Acxiom customer files containing personal information. The intrusion cost Acxiom over $5.8 million. c. Cyber-attacks left high-profile sites such as Amazon.com, eBay, Buy.com, and CNN Interactive staggering under the weight of tens of thousands of bogus messages that tied up the retail sites' computers and slowed the news site's operations for hours. d.

MicroPatent, an intellectual property firm, was notified that their proprietary information would be broadcast on the Internet if they did not pay a $17 million fee.
