How Banks Can Turn Fraud Reports Into Actionable Leads With OSINT

Fraud prevention remains one of the biggest priorities for financial institutions. Banks invest heavily in transaction monitoring, customer education, fraud detection technologies, and security controls designed to stop scams before money leaves a customer's account.

Yet despite these efforts, fraud continues to grow.

In a recent article for The Sunday Times, Liz Ziegler, Fraud Director at Lloyds Banking Group, highlighted the scale of the challenge facing the banking sector. According to Lloyds' data, around seven in ten shopping scam reports from customers originate on Meta’s social media and messaging platforms. The bank also estimates that consumers are now sending £66 million annually to fraudsters after falling victim to scam advertisements on these platforms, up from £27 million in 2023.

While much of the discussion surrounding fraud focuses on prevention and social media platforms' responsibility, there is also an opportunity for banks to leverage the growing volume of fraud reports through OSINT.

From Isolated Investigations to Comprehensive Analysis

When customers report fraud, the report they make will include information about the fraudster, including:

• Profile names
• Usernames
• Phone numbers
• Email addresses
• Websites and online storefronts
• Payment instructions

While reported identifiers may be false or disposable, they can still help investigators establish context around the incident.

For example, a phone number may be linked to additional online accounts, providing opportunities to prevent impact on victims. A username may reveal other advertisements, marketplace listings, or online activity that helps investigators tackle the fraudster

Viewed in isolation, these incidents appear unrelated. However, investigators frequently discover common elements hidden beneath the surface. By cross-referencing publicly available information associated with the case, investigators can begin linking cases that would otherwise remain disconnected.

Turning Reports Into Actionable Intelligence

The most effective fraud programs increasingly operate as intelligence functions rather than purely reactive case management teams. Rather than simply resolving individual complaints, investigators seek to answer broader questions:

• Are multiple customers being targeted by the same operation?
• Are certain fraud tactics becoming more common?
• Are specific identifiers appearing repeatedly across reports?
• Are there signs of organized criminal activity?
• Which threats present the greatest risk to customers?

OSINT helps investigators develop answers to these by transforming customer-reported information into actionable intelligence.

This intelligence can support fraud investigations, suspicious activity reporting, internal risk assessments, and wider efforts to understand emerging fraud trends.

Strengthening Collaboration Across the Financial Crime Ecosystem

Banks rarely investigate fraud in isolation. Law enforcement agencies and networks of financial institutions all play important roles in detecting and disrupting criminal activity.

The intelligence developed through fraud investigations can provide valuable context for these collaborative efforts. Patterns identified across reports may help reveal emerging threats, recurring tactics, or larger criminal networks that extend beyond a single institution.

The more effectively organizations can identify and contextualize these patterns, the greater their ability to support broader disruption efforts.

Every Fraud Report Is a Piece of Threat Intelligence

The statistics highlighted by Lloyds demonstrate the scale of fraud facing both consumers and financial institutions. As the volume of reported scams continues to rise, banks are collecting vast amounts of information about how fraudsters operate, communicate, and target victims.

Within every customer report are potential indicators, connections, and investigative leads.

By applying OSINT techniques to these digital traces, banks can move beyond simply responding to fraud after the fact. They can build intelligence, identify patterns, and gain a deeper understanding of the threats affecting their customers.

In an environment where fraud tactics continue to evolve, the ability to transform individual fraud reports into actionable intelligence may become one of the most valuable tools available to modern fraud investigation teams.
