Forensic Accounting in the Digital Age: Following Money Through Apps and Wallets
Anslem Oshionebo, CFE, on how forensic investigations trace funds through mobile money, fintech apps and crypto wallets.

Money used to move through a small number of banks, leaving paper trails that investigators knew how to read. Today it moves through mobile wallets, payment apps, virtual cards and crypto exchanges, often across borders in minutes. Forensic accounting has had to change with it. As a Certified Fraud Examiner who has led fraud investigations and now leads an asset tracing firm, I see both the new challenges and the new evidence.
The trail is still there
Digital money is not invisible. Every app and wallet provider keeps records: account holders, devices, IP addresses, linked bank accounts and transaction histories. Blockchains record every crypto transfer permanently. The challenge is not a lack of data but its fragmentation across many providers and jurisdictions.
Modern techniques
- Data analytics: analysing entire transaction populations to spot patterns, round amounts, unusual timing and links between accounts.
- Blockchain analysis: following crypto flows across addresses to exchanges where identities are known.
- Device and identity linking: connecting accounts through shared devices, phone numbers and documents.
- Open source intelligence: company registries, court records, property records and public profiles.
Legal process matters
Most valuable records are held by third parties. Obtaining them requires court orders, regulator cooperation or mutual legal assistance across borders. Evidence must be gathered lawfully and preserved properly if it is to support recovery or prosecution.
Speed decides outcomes
Funds can be moved again within hours. Early freezing orders and rapid engagement with exchanges and payment providers often decide whether money is recovered or lost.
Anatomy of a digital investigation
- Scope: define the allegation, period, people and entities involved.
- Preserve: secure emails, devices, accounting data and bank records before they are altered.
- Analyse: use data analytics to test entire populations of transactions for anomalies such as round sums, duplicates, unusual timing and payments to related parties.
- Trace: follow funds through bank accounts, payment apps, mobile wallets and, where relevant, blockchain addresses.
- Interview: speak to witnesses and subjects with evidence in hand.
- Report: present findings clearly enough to support civil recovery, disciplinary action or prosecution.
Common fraud schemes found in data
- Fictitious suppliers sharing bank details or addresses with employees.
- Payroll ghosts: employees who no longer work but are still paid.
- Expense reimbursements split to stay below approval limits.
- Manual journal entries posted at unusual times by unusual users.
- Revenue recorded at period end and reversed shortly after.
Skills for the next generation of forensic accountants
The profession now needs accountants who can query databases, understand how payment systems and digital wallets work, read blockchain data and communicate findings to lawyers and boards. Professional credentials such as the Certified Fraud Examiner designation, combined with technical training, prepare practitioners for this work.
A leader's view: prepare before an allegation arrives
The quality of an investigation is often decided before it starts. Organisations that have retained emails and transaction data, documented their processes and controlled access to systems give investigators a clear trail. Those with scattered records, shared passwords and deleted mailboxes make the truth harder to establish and recovery less likely.
Leaders can prepare in practical ways:
- Set data retention policies that preserve financial records, emails and system logs for an appropriate period.
- Maintain a whistleblowing channel that people trust, with a clear process for handling reports.
- Agree in advance who leads investigations, which external specialists to call and how legal privilege will be protected.
- Train managers to escalate concerns without tipping off suspects or destroying evidence.
When an allegation arrives, respond quickly but carefully. Preserve evidence first, then investigate. Avoid confronting suspects before data is secured. Keep the circle of knowledge small. Communicate with the board and, where required, regulators and auditors. As a Certified Fraud Examiner, I have seen that calm, structured responses produce better outcomes than hurried ones, both for establishing the facts and for recovering losses.
The skill set has widened
Today's forensic teams combine accountants, data scientists, investigators and lawyers. The fundamentals are the same as ever: follow the money, document everything and let the evidence speak. The tools are simply faster.
Common questions
What does a forensic accountant do?
A forensic accountant investigates financial irregularities, traces funds, quantifies losses and presents evidence suitable for legal proceedings or disciplinary action.
Can cryptocurrency transactions be traced?
Yes. Public blockchains record every transaction, and specialist analytics tools can follow funds between addresses and identify when they reach regulated exchanges.
