Identity and Internet Crimes: Trends, Methods, and Mitigation

The Rise of Identity and Internet Crimes

Emergence and Growth of Identity Crimes

  • Identity crime has become a primary public and law enforcement concern, mirroring the general growth in computer crimes over several decades.

  • The exponential growth in identity theft is largely attributed to new opportunities created by technological and commercial advancements.

  • This has led to an alarming rise in the fraudulent use of personal information like Social Security numbers, dates of birth, and credit card numbers for personal gain.

  • Law enforcement agencies have been forced to redirect scarce resources to mitigate this threat.

Trends and Statistics (Congressional Research Service Report)

  • The number of identity theft complaints peaked during 2007 and 2008.

  • Complaints decreased in both 2009 and 2010.

  • Despite the decrease, identity theft remains the most frequent type of consumer fraud complaint.

  • In 2010, approximately 8.1 million8.1 \text{ million} Americans were victims of identity fraud.

  • The average victim suffered a mean loss of 631</strong>fromthesecrimes.</p></li><li><p>Amoretroublingtrendisthecontinuedincreasein<strong>aggravatedidentitytheftcases</strong>relativetothetotalnumberofidentitycrimes.</p></li></ul><h4id="7d644ed0deb24d88a4a995ecc26cc897"datatocid="7d644ed0deb24d88a4a995ecc26cc897"collapsed="false"seolevelmigrated="true">TheRoleofSocialSecurityNumbers(SSNs)</h4><ul><li><p>TheincreasinguseofSSNsaspersonalidentifierscontributestothesetrends.</p></li><li><p>Decadesago,SSNswererarelyreferredtobythoseunderretirementage.</p></li><li><p>Now,SSNsareusedforawiderangeofbusinesstransactions,particularlyfor<strong>openingnewlinesofpersonalcredit</strong>.</p></li><li><p>Theiruseextendsbeyondcredittransactionstoincludemedicalrecords,motorvehicledriverslicenses,andeducationalandemploymentrecords.</p></li><li><p>SomecardealersevenrequestSSNsbeforeatestdrive.</p></li><li><p><strong>Theftopportunitiesincreasedirectlywiththefrequency</strong>consumersarerequiredtouseSSNsbycommercialandgovernmentalenterprises.</p></li><li><p>Policymakersareexploringoptions,includinglegislation,to<strong>reducetheuseofSSNsbyprivatecompanies</strong>.</p></li></ul><h4id="cf6f1fe2b3a54b2bbd02be55012d0b1b"datatocid="cf6f1fe2b3a54b2bbd02be55012d0b1b"collapsed="false"seolevelmigrated="true">MethodsofIdentityTheft</h4><ul><li><p><strong>Lowtechmethods</strong>:</p><ul><li><p><strong>"Dumpsterdiving"</strong>:Rummagingthroughprivateorcommercialtrashfordiscardedbillsorpreapprovedcreditapplications.</p></li></ul></li><li><p><strong>Sophisticatedandtechnologicallybasedmethods</strong>(usedbyorganizedthievesformassquantitiesofinformation):</p><ul><li><p><strong>Hackingcorporatedatabases</strong>usedforonlinetransactions.</p></li><li><p><strong>Bribingemployees</strong>withinternalaccesstocustomeridentifiers.</p></li></ul></li></ul><h4id="b24d4fce08be45f9912ca012775c290e"datatocid="b24d4fce08be45f9912ca012775c290e"collapsed="false"seolevelmigrated="true">FinancialImpactofDataTheft</h4><ul><li><p>Thelossofsensitivepersonalinformationiscostly.</p></li><li><p>Estimatesfrom<strong>2007</strong>indicateU.S.businesseslostover<strong>631</strong> from these crimes.</p></li><li><p>A more troubling trend is the continued increase in <strong>aggravated identity theft cases</strong> relative to the total number of identity crimes.</p></li></ul><h4 id="7d644ed0-deb2-4d88-a4a9-95ecc26cc897" data-toc-id="7d644ed0-deb2-4d88-a4a9-95ecc26cc897" collapsed="false" seolevelmigrated="true">The Role of Social Security Numbers (SSNs)</h4><ul><li><p>The increasing use of SSNs as personal identifiers contributes to these trends.</p></li><li><p>Decades ago, SSNs were rarely referred to by those under retirement age.</p></li><li><p>Now, SSNs are used for a wide range of business transactions, particularly for <strong>opening new lines of personal credit</strong>.</p></li><li><p>Their use extends beyond credit transactions to include medical records, motor vehicle driver’s licenses, and educational and employment records.</p></li><li><p>Some car dealers even request SSNs before a test drive.</p></li><li><p><strong>Theft opportunities increase directly with the frequency</strong> consumers are required to use SSNs by commercial and governmental enterprises.</p></li><li><p>Policymakers are exploring options, including legislation, to <strong>reduce the use of SSNs by private companies</strong>.</p></li></ul><h4 id="cf6f1fe2-b3a5-4b2b-bd02-be55012d0b1b" data-toc-id="cf6f1fe2-b3a5-4b2b-bd02-be55012d0b1b" collapsed="false" seolevelmigrated="true">Methods of Identity Theft</h4><ul><li><p><strong>Low-tech methods</strong>:</p><ul><li><p><strong>"Dumpster diving"</strong>: Rummaging through private or commercial trash for discarded bills or preapproved credit applications.</p></li></ul></li><li><p><strong>Sophisticated and technologically-based methods</strong> (used by organized thieves for mass quantities of information):</p><ul><li><p><strong>Hacking corporate databases</strong> used for online transactions.</p></li><li><p><strong>Bribing employees</strong> with internal access to customer identifiers.</p></li></ul></li></ul><h4 id="b24d4fce-08be-45f9-912c-a012775c290e" data-toc-id="b24d4fce-08be-45f9-912c-a012775c290e" collapsed="false" seolevelmigrated="true">Financial Impact of Data Theft</h4><ul><li><p>The loss of sensitive personal information is costly.</p></li><li><p>Estimates from <strong>2007</strong> indicate U.S. businesses lost over <strong>5 \text{ million} due to confidential electronic data theft by hackers.

    • The ability to buy accounts from around the world demonstrates that identity theft and fraud have no boundaries.

    • Carding markets facilitate real-world identity theft and fraud:

      • Individuals offer cash-out services to convert electronic funds into physical money.

      • Buyers can purchase skimming devices to attach to ATMs or point-of-sale terminals to capture magnetic stripe data from cards.

      • Sales of passports, drivers’ licenses, and financial records enable more efficient real-world identity theft.

    Significant Cases of Identity Theft and Carding

    • Long Island Software Company Employee: A former employee originated a crime ring that cost consumers 2.7 million</strong>.</p><ul><li><p>Thesuspectsoldcreditreportsofover2.7 \text{ million}</strong>.</p><ul><li><p>The suspect sold credit reports of over30,000people(includingnames,SSNs,creditinfo)toblackmarketidentitythieves.</p></li><li><p>Thisinformationwasusedtofraudulentlyobtainconsumergoods.</p></li><li><p>Eachvictimscredithistorywassoldforonly<strong>people (including names, SSNs, credit info) to black market identity thieves.</p></li><li><p>This information was used to fraudulently obtain consumer goods.</p></li><li><p>Each victim’s credit history was sold for only <strong>30.

  • Federal Conviction of Military Officer Data Thief: A defendant was convicted for fraudulently obtaining names and SSNs of high-ranking military officers from internal government websites.

    • He used this information to apply for credit cards and lines of credit online.

    • Sentenced to 4141 months in prison and ordered to pay over 186,000186,000 in restitution.

  • Insurance Firm Employee Fraud: A former temporary employee of an insurance firm used policyholders’ bank account information to deposit over 764,000764,000 in counterfeit bank checks.

  • Identity Theft-Drug Smuggling Scheme: Seven defendants were convicted.

    • They used stolen SSNs to obtain employment and identification documents to facilitate heroin and methamphetamine smuggling from Mexico.

    • A number of defendants also used stolen identities to claim earned income tax credits on IRS tax forms.

  • CASE #1: The ShadowCrew (2002-2004):

    • Opened a website in 2002 and developed a brisk trade in credit cards, financial information, and identity documents.

    • Over 1 million1 \text{ million} credit cards were sold; there were over 2,0002,000 registered members.

    • Website was taken down on October 26, 2004, by the U.S. Secret Service and international police agencies.

    • Homes of 2828 members were raided; 1212 individuals pled guilty to charges ranging from computer fraud and abuse to document fraud and conspiracy.

    • The group leader, 3232-year-old Andrew Mantovani, received 3232 months in federal prison.

Law Enforcement and Legislative Responses

  • Federal law enforcement and the criminal justice system are responding through new legislation and consumer awareness programs.

  • Identity Theft and Assumption Deterrence Act of 1998:

    • Makes it a federal crime to knowingly transfer or use, without lawful authority, another person's means of identification with the intent to commit or aid any unlawful activity (federal law violation or state/local felony).

    • Violations are punishable by up to 1515 years in prison.

    • While significant, the impact of such laws may be largely symbolic for many victims due to prosecution difficulties.

Challenges in Prosecuting Identity Crimes

  • Identity crimes remain extremely difficult to prosecute once detected.

  • Many cases are detected too late for adequate investigation.

  • These cases are labor-intensive and often require collaborative efforts from federal, state, and local law enforcement.

  • The actual monetary losses in many individual identity theft cases may be considered too small to dedicate substantial prosecutorial resources.

Future Strategies to Mitigate Identity Theft: Proactive Approaches

  • Experts believe consumer awareness and monitoring programs are the most viable avenue to thwart identity theft growth, given prosecution difficulties.

  • Federal Trade Commission (FTC) Identity Theft Clearinghouse:

    • Collects identity theft complaints.

    • Provides victims with referral information and resources to restore credit history and financial status.

    • Established a hotline for victims.

  • Fundamental problems with traditional strategies:

    • Identity thieves are extremely difficult to catch.

    • They often steal amounts too small to garner significant attention from local law enforcement.

    • These issues reduce the effectiveness of reactive or post-occurrence strategies.

  • Observers underscore the need for more proactive mitigation strategies to prevent identity theft before it occurs.

The Concept of Fractured Identities (Birch)

  • Birch argues large-scale identity theft occurs because citizens are routinely required to provide too much personal information or "parts" of their identity.

  • Most transactions require verification of only a single piece of data, yet we are asked to provide many unnecessary data points.

  • Identity theft increases with the amount of personal information made available in each transaction.

  • We don't have one single identity but many "fractured" identities depending on the situation.

  • The proposed solution is to only reveal the specific part of our identity required to complete each individual transaction.

Internet Fraud: General Trends and Statistics

  • The Internet's growth over the last decade (communications, research, consumer spending, B2B transactions) has created unparalleled opportunities but also fresh avenues for fraud and abuse.

  • Many online fraud schemes are simply new takes on old themes (e.g., chain letter hoaxes, confidence schemes, bait-and-switch cons) adapted to an electronic medium.

  • The increasing use of the Internet has led to an alarming growth in fraudulent schemes.

  • According to NWCCC reporting rates:

    • Consumer complaints concerning online fraud rose from 16,83816,838 in 2000 to over 75,00075,000 in 2002.

    • The IC3 has seen an increase in auction fraud reports over time; the average loss per complaint was 610.

    • Common methods of defrauding participants:

      • Nondelivery of goods: The most prevalent form; victims often have little recourse as payment is received, and they lack physical address/description of perpetrator.

      • Misrepresentation: Sellers purposely misrepresent item quality or characteristics through descriptions or altered pictures.

      • "Shill bidding": Intentional fake bidding by the seller to artificially inflate the item's auctioned price.

      • "Fee stacking": Sellers add hidden charges (often inflated shipping costs) to the item's cost prior to delivery.

      • In March 2002, sentenced to three years in prison and ordered to pay restitution; victims averaged 1,2001,200 in individual losses.

    • CASE #2: Teresa Smith (Massachusetts):

      • One of the largest online auction fraud schemes on record, with over 300300 individual complaints from April 2001 to October 2002.

      • Scheme: sold computers, required upfront payment, then did not send merchandise or issue refunds.

      • Spent victims’ money on living expenses, a new vehicle, and advertising.

      • Changed online identity when complaints were reported.

      • Detected after investigators uncovered over 800,000800,000 in fraudulent proceeds.

      • Sentenced in 2003 to nearly five years in prison.

    Financial Institution Fraud
    • Involves attempts to conceal the truth from deposit and lending institutions to gain monetarily.

    • Examples: credit/debit card fraud and identity theft.

    • Credit card fraud is one of the most widely reported Internet frauds.

    • Identity theft is a primary concern for law enforcement and the public.

    Investment Frauds
    • Defined as "deceptive practices involving the use of capital to create more money."

    • Includes traditional stock market schemes and pyramid business schemes, all of which can be conducted online.

    Communication Frauds
    • Involving new technologies, these have skyrocketed (e.g., thefts of wireless phone codes and satellite communication devices).

    Confidence Schemes
    • Involve a breach of personal trust and are among the most widely practiced and familiar forms of Internet fraud.

    • Typically use email or online sites as the primary medium, rather than mail or telephone.

    • Widely perpetrated Internet confidence schemes include:

      • Online auction fraud.

      • The Nigerian "419" fraud.

      • Chain letter hoaxes.

      • "Urban legends" passed along through electronic mailings.

    Detecting Phishing Emails: The PILFER System

    • Researchers at Carnegie Mellon University developed a method for detecting phishing emails.

    • Their approach, called "PILFER", is designed to detect intentionally deceptive communication.

    • Methodology:

      • (1) Extracting data contained in the phishing email.

      • (2) Collecting additional information from external sources.

    • Data used by PILFER:

      • Web addresses.

      • Website domain names.

      • Number of links in the email.

      • HTML email content.

Legal Framework for Internet Fraud: The Computer Fraud and Abuse Act (CFAA)

  • The Computer Fraud and Abuse Act (CFAA) has become the primary vehicle for prosecuting Internet fraud crimes.

  • Initially enacted by Congress in 1984 to protect classified information on government computers.

  • Scope expanded in 1986 and again in 1996.

  • The 1996 amendments incorporated computers involved in interstate and/or foreign commerce.

  • Essentially, the CFAA covers most fraudulent business practices conducted over the Internet.
