Correct answer: They can help them to commit identity theft

Social Security Numbers (SSNs) are one of the most sensitive and valuable pieces of personally identifiable information (PII) in the digital age. For cybercriminals, gaining access to someone’s SSN opens a gateway to a wide array of fraudulent activities, with identity theft at the top of the list. In this in-depth explanation, we’ll explore why SSNs are so useful to cybercriminals, how they’re exploited, and what consequences they bring for victims.

Understanding Social Security Numbers

A Social Security Number is a unique, 9-digit number assigned by the government—primarily in the United States—for purposes such as tracking earnings, tax reporting, and determining eligibility for social benefits. Because this number is widely used as a personal identifier, many institutions—banks, healthcare providers, employers, and credit bureaus—require it for verification.

This makes the SSN a master key to a person’s identity.

Why Cybercriminals Target SSNs

1. Identity Theft and Fraudulent Activities

The primary reason cybercriminals want SSNs is to commit identity theft. Once they have your SSN, especially when combined with your name, birthdate, and address, they can:

Open bank accounts in your name
Apply for credit cards or loans
File fraudulent tax returns to claim refunds
Access your medical records or obtain prescriptions
Apply for unemployment benefits or government aid
Sign up for utilities or rent properties

All of this can happen without your knowledge, and the damage may only become apparent after weeks or months of criminal activity.

2. Long-Term Use and Value

Unlike a password that can be changed, an SSN is permanent. If your SSN is leaked, it can be misused for years, unless steps like credit freezes or fraud alerts are taken. This long-term value makes SSNs more attractive than credit card numbers, which can easily be cancelled or replaced.

3. Ease of Sale on the Dark Web

SSNs are often bundled with other personal information (called fullz on the dark web) and sold to other criminals. These full identity packets may include:

Name
Date of birth
SSN
Address
Phone number
Credit card or bank account info

Cybercriminals buy these datasets to create synthetic identities or commit fraud, making SSNs lucrative in underground markets.

Why the Other Options Are Incorrect

Let’s explore why the other choices don’t accurately reflect the role of SSNs in cybercrime:

“They reduce the probability of detection”
This is not true. In fact, using someone’s SSN can increase the chances of detection because there are numerous monitoring services and regulations that trigger alerts when someone tries to use your SSN for suspicious activity. SSNs don’t mask the criminal’s actions—they enable the initial fraud.
“They provide improved financial stability”
This is a misleading statement. SSNs themselves don’t improve financial stability for anyone—especially not criminals. The intent of using an SSN is not to achieve stability but to exploit someone else’s credit history or financial standing. The only “gain” is illegitimate, and the victim’s financial health typically suffers.
“They can use them to fake utility bills”
While SSNs may be used to sign up for utilities fraudulently, they are not required to “fake” utility bills. Faking a bill usually requires document editing tools, not someone’s SSN. However, an SSN may help open a utility account under a false identity, which is part of broader identity theft—not the creation of fake documents.

Real-Life Examples of SSN Exploitation

The Equifax Data Breach (2017)
- One of the largest breaches in history exposed the SSNs of over 145 million Americans.
- Criminals used the leaked data to open fake accounts, commit tax fraud, and more.
IRS Tax Refund Scams
- Thieves use stolen SSNs to file early tax returns and claim refunds.
- Victims then face IRS delays and audits when filing their legitimate returns.
Healthcare Fraud
- Stolen SSNs enable access to insurance services and prescriptions under the victim’s name.
- This not only results in financial damage but can corrupt medical records.

The Consequences for Victims

When someone’s SSN is compromised, they can experience:

Credit score damage
Loan or credit application denials
IRS disputes or audits
Debt collection attempts for loans they never took
Legal battles to clear their name
Emotional distress and loss of trust in digital systems

Restoring your identity can take months or even years, and it often requires professional legal and financial support.

How Cybercriminals Obtain SSNs

Some common methods include:

Phishing emails or fake websites
Data breaches of companies or institutions
Malware infections on user devices
Social engineering attacks
Dark web purchases

Sometimes even dumpster diving or stealing physical documents can expose SSNs, showing that both digital and analog methods are threats.

Prevention and Protection

If you want to protect your SSN:

Never share it via email or phone unless verified
Enable credit monitoring or identity theft protection
Place a fraud alert or credit freeze with credit bureaus
Shred sensitive documents before discarding them
Be cautious with online forms and suspicious links

Government agencies like the Federal Trade Commission (FTC) and Social Security Administration (SSA) offer support and reporting mechanisms for victims of SSN misuse.

Final Thoughts

Cybercriminals highly value Social Security Numbers because they act as a passport into someone’s financial, medical, and personal life. Their primary use is to commit identity theft, making the correct answer absolutely clear.

Correct Answer: They can help them to commit identity theft

Protecting your SSN is essential in the digital era. By understanding how and why cybercriminals exploit SSNs, individuals and organizations can take more effective steps to defend against identity theft and reduce the chances of catastrophic personal or financial damage.
