Synthetic identity fraud: What is it & how to prevent it

Synthetic Identity Fraud

Every year, thousands of synthetic identity frauds are committed using bits and pieces of sensitive information leaked through improperly redacted documents. This isn't just another cybersecurity buzzword—it's a sophisticated fraud scheme where criminals patiently build fake identities using real Social Security numbers from your documents, combined with fabricated names and addresses. The result? A perfect storm of financial fraud that costs organizations billions annually, with your company's unredacted files potentially providing the building blocks.

While most organizations focus on protecting against direct data breaches, many overlook a quieter but equally dangerous threat: sensitive information hiding in plain sight within poorly redacted documents. These seemingly harmless oversights in document handling are becoming a goldmine for bad actors building synthetic identities.

Key points:

  • What’s at risk: Financial records, HR forms, and healthcare files with sensitive details (e.g., Social Security numbers, addresses).
  • Common mistakes: Using basic tools (like PDF editors) that leave hidden data and metadata recoverable, redacting documents manually.
  • How synthetic identity frauds happens: Fraudsters slowly build credit profiles for fake identities, gaining trust before executing large scams.

Solutions:

  1. Use AI-powered redaction tools to fully remove sensitive data.
  2. Implement clear redaction policies and dual-review systems.
  3. Train employees on secure document handling and proper redaction techniques.
  4. Monitor synthetic fraud patterns with tools like machine learning and behavioral analytics.

Protecting sensitive information and adopting advanced verification systems can significantly reduce the risks of synthetic fraud.

Identifying documents at risk of synthetic identity theft

Every organization is sitting on a potential goldmine of sensitive data that fraudsters are eager to exploit. Financial records, HR forms, and healthcare files aren't just documents—they're comprehensive identity packages waiting to be compromised. A single unredacted employee file might contain everything a criminal needs: Social Security numbers, addresses, birth dates, employment history, and even family member information. What makes this particularly dangerous is that these documents are handled and shared daily as part of normal business operations.

Common mistakes in document redaction

The gap between perception and reality in document redaction is where most organizations become vulnerable. While 91% of companies believe their redaction methods are secure, basic tools like PDF highlighters and black markers remain their primary protection. These methods aren't just ineffective—they're dangerous. The 2017 Equifax breach, which exposed sensitive data from over 147 million people, serves as a stark reminder of how improper document security can lead to catastrophic identity theft.

Think your redacted documents are secure? Here's what fraudsters can still access:

  • Hidden data layers in PDF files that retain all original text, despite visible black boxes
  • Document properties and metadata containing sensitive information about authors, creation dates, and edit history
  • Headers, footers, and attachments often overlooked during manual redaction
  • Reversible digital markups that can be uncovered using basic PDF software available to anyone

The most concerning part? These vulnerabilities persist even in organizations with dedicated security teams, primarily because traditional redaction methods haven't evolved to match modern threats. When a single overlooked document can compromise thousands of identities, relying on manual redaction or basic digital tools isn't just risky—it's negligent.


Redaction error Synthetic Identity Theft Risk
Hiding data with visual objects, instead of removing it from the document Sensitive information remains in document layers, allowing anyone with basic PDF tools to instantly expose SSNs, banking details, and personal data
Manual redaction inconsistencies Critical identifiers slip through in forgotten areas like headers, footnotes, and metadata, creating a perfect paper trail for identity thieves
Reversible digital markups What looks secure on screen becomes an open book - fraudsters can easily restore hidden text using freely available PDF readers, exposing entire documents
Insufficient quality control Without systematic verification, even a single missed redaction can compromise an entire document set - one oversight can expose thousands of records

Examples of synthetic identity fraud from unredacted data

Synthetic identity fraud has emerged as one of the fastest-growing types of financial crime, with projected losses reaching $23 billion by 2030. These schemes combine stolen data—like Social Security numbers found through unredacted documents—with fabricated information to create seemingly legitimate identities. What makes synthetic fraud particularly effective is its patient approach: criminals slowly build credit histories for these synthetic identities, establishing trust over time before executing their schemes.

When sensitive information leaks through improper redaction, it doesn't just enable a single instance of fraud—it provides criminals with authentic data points they can use repeatedly in different combinations. These synthetic identities can then operate undetected within the financial system for months or years, accumulating credit and trust before the fraud is discovered.

To minimize these risks, organizations need to implement effective redaction tools and practices while storing sensitive data. Preventing data exposure is far easier - and far less costly - than dealing with the fallout from synthetic identity fraud.

How to prevent synthetic identity theft?

In 2022, data breaches in the U.S. averaged a staggering $9.44 million per incident, with synthetic identity thefts making up 19% of all breaches. To counter these risks, organizations need to incorporate strong security practices into their document workflows.

Creating a redaction policy that actually works

Most organizations know they need a redaction policy, but the difference between a document that gathers dust and one that actively prevents fraud lies in the details. An effective policy serves as your organization's blueprint for protecting sensitive information, turning abstract security goals into concrete, everyday practices.

Key elements of a redaction policy include categorizing documents based on sensitivity, aligning with regulations like GDPR and CCPA, and implementing dual-review systems for quality assurance. Regularly updating the policy helps maintain compliance as laws and standards change.

Moving from policy to redaction tools

A policy is only as good as the tools that implement it. Think of your redaction policy as the blueprint and your redaction tools as the construction crew—you need both working in perfect sync. When evaluating redaction solutions, focus on professional tools that can:

  • Scale with your document volume
  • Detect and remove all types of sensitive data
  • Integrate seamlessly with existing workflows
  • Provide comprehensive audit trails

Feature Manual tools AI-powered solutions

Monitoring and responding to synthetic identity fraud threats

Identifying synthetic fraud patterns

Detecting synthetic identity fraud relies heavily on tools like machine learning and behavioral analytics. These technologies identify unusual patterns and warning signs such as:

Spotting these fraud patterns is just the first step; organizations must also act quickly to address breaches when they occur.

Responding to data breaches

When data is exposed, swift action is critical. Organizations need to:

  • Isolate affected systems immediately to contain the breach.
  • Document all details, including the type of data exposed, unredacted fields, and a timeline of events.
  • Notify affected parties, stakeholders, and regulatory bodies without delay.

This structured approach limits the damage and reduces the risk of synthetic identities being created from leaked data.

But fighting synthetic fraud can't be done in isolation. Broader collaboration is key.

Working with financial institutions and regulators

While internal monitoring and quick responses are essential, partnering with financial institutions and regulators strengthens defenses on a larger scale. Sharing synthetic fraud pattern securely and ensuring compliance with FCRA and GLBA requirements through regular audits and updates are critical steps.

Multi-layered verification methods, like biometric authentication, have cut synthetic identity fraud attempts by as much as 85%. Meanwhile, behavioral analytics tools monitor real-time anomalies, flagging suspicious activities for immediate review. These combined efforts showcase the effectiveness of proactive monitoring and collaboration.
