In the annals of financial security, the Global Banking Fraud Survey of 2019 painted a concerning picture: over half of the participating institutions reported an unsettling increase in fraudulent activities. This uptick was not just a minor inconvenience; it had significant global ramifications, both in terms of frequency and financial repercussions. Fast forward to 2023, and the APAC Digital Banking Fraud Trends Report unveiled a disheartening reality—bank fraud was on the rise, with scams accounting for an alarming 54% of all reported incidents. Among these, voice scams experienced an extraordinary 200% increase between 2022 and 2023, illustrating just how rapidly these criminal tactics are evolving.
Against a backdrop of worldwide turmoil—stemming from the lingering effects of the pandemic and ongoing geopolitical tensions—fraudsters have become increasingly cunning in their methods. They have learned to exploit the heightened stress and anxiety that many individuals are feeling, employing strategies that focus on manipulating human emotions. By utilising remote access tools, they have managed to stay a step ahead of even the most advanced cybersecurity measures, leaving financial institutions grappling with their defences.
As we embark on a journey to explore the multifaceted realm of bank fraud, we aim to provide insights that can aid financial institutions in strengthening their protective measures. We will also delve into the transformative potential of artificial intelligence and machine learning in the battle against banking fraud, showcasing how these technologies can be instrumental in detection and prevention.
The Varied Facets of Bank Fraud
In the complex world of banking, the spectre of fraud casts a long shadow, presenting a myriad of challenges that institutions must confront. From sophisticated cyberattacks to clever social engineering schemes, various forms of fraud threaten the integrity of the financial sector. In this section, we will navigate through the different types of bank fraud, examining each one closely to understand their intricacies and the potential consequences they hold for both banks and their customers.
Card Fraud
Among the myriad types of banking fraud, credit card fraud stands out as one of the most prevalent. Here, deceitful individuals gain unauthorised access to various payment cards—credit, debit, gift, or prepaid—seeking illicit financial gain. The tactics employed can range from skimming devices that capture card information to cloning cards entirely.
The financial toll from card fraud has been staggering; in 2023 alone, global losses reached a staggering $34 billion, with projections suggesting that this figure could climb to $43 billion by 2026 (source: https://www.clearlypayments.com/blog/credit-card-fraud-in-2023/).
Check Fraud
In the shadowy world of financial deception, check fraud is a cunning scheme in which unscrupulous individuals exploit both traditional paper checks and their digital counterparts to unlawfully siphon funds. These perpetrators are not limited in their tactics; they might concoct various schemes, such as issuing checks from accounts that are either closed or belong to them, forging signatures with deft precision, or even crafting entirely fictitious checks that never had any legitimacy.
A glance at the 2022 AFP® Payment Fraud and Control Report reveals a stark reality: in 2021, checks were the most common form of payment fraud, affecting a staggering 66% of victims, while wire transfers trailed behind at 37%. This alarming data highlights the pervasive nature of check fraud in our financial landscape.
Friendly Fraud
Often cloaked in the guise of a seemingly innocent transaction, friendly fraud—also known as chargeback fraud—occurs when an honest payment made through credit or debit cards is later contested. Unlike traditional fraud scenarios that involve shadowy figures lurking in the background, friendly fraud represents a troubling twist: it is a form of first-party abuse, where the very customer who initiated the transaction later claims that it was unauthorised or fraudulent.
In this unsettling situation, a consumer who once completed a legitimate purchase suddenly turns around to dispute the charge, creating a tangled web of confusion and distrust in the merchant-customer relationship.
New Account Fraud
Venturing further into the realm of deception, we encounter new account fraud—an insidious practice where an imposter opens an account with the sole purpose of committing various fraudulent acts. Often, these fraudsters employ stolen or fabricated identities, sometimes plucking information from data breaches or phishing schemes. Alarmingly, they may even resort to using the personal details of vulnerable individuals, including children, deceased persons, or those experiencing homelessness.
In some cases, the fraudster might simply misuse their own identity to engage in deceitful activities, which falls under the category of first-party fraud. Alternatively, they can create synthetic identities by melding genuine and stolen information. Once these fraudulent accounts are established, the perpetrators unleash a wave of charges or issue checks under the name of their unsuspecting victims.
Account Takeover (ATO)
Imagine a scenario where deceitful individuals manage to infiltrate personal accounts without permission, a crime commonly referred to as Account Takeover (ATO). This insidious act often begins with the theft of login details, and the methods employed by these fraudsters are as varied as they are cunning.
One prevalent technique is phishing, where the perpetrators craft seemingly legitimate emails or text messages that lure unsuspecting victims to counterfeit bank login pages. These false fronts are designed to extract sensitive information, such as usernames and passwords, from those who fall into their trap.
Another method is credential stuffing, sometimes termed “brute force” attacks. Here, sophisticated bots are unleashed by the fraudsters, tirelessly attempting to log in using random credentials that have been pilfered or purchased from the dark web. With each attempt, they inch closer to breaching an account’s security.
Then there’s social engineering—an art of manipulation in which fraudsters play psychological games, often employing intimidation tactics to coerce individuals into revealing confidential information. It’s a dangerous dance of deceit that exploits human trust.
Cybersecurity vulnerabilities also present fertile ground for these criminals. They may unleash malware, conduct ransomware attacks, or capitalise on data breaches to exploit weaknesses in a bank’s security framework, leaving chaos in their wake.
One particularly alarming trend is call centre fraud, where organised crime rings target call centres or individuals through impersonation and social engineering. Predominantly operating from Southeast Asian countries like Indonesia, Thailand, Malaysia, Cambodia, and Myanmar, these groups have found this method to be more lucrative than even human trafficking. The allure of profit has driven many criminal networks to pivot towards scam call centres.

Money Laundering
In another shadowy realm of financial crime lies money laundering—a process through which illicitly acquired funds are transformed into seemingly legitimate assets. These funds, often referred to as “dirty money,” stem from a variety of nefarious activities, including drug trafficking, human trafficking, corruption, embezzlement, and illegal gambling. Organised fraud rings, or gangs, frequently orchestrate these operations.
The laundering journey unfolds in three distinct stages. The first step is placement, where small sums of money are carefully introduced into the financial system. This is done in amounts deliberately kept below the reporting threshold set by Anti-Money Laundering (AML) regulation, a tactic known as “smurfing.”
Following placement comes layering. In this phase, the dirty money undergoes a series of transactions—perhaps it is used for purchases or invested in various ventures. This complex web of activity is often routed through holding companies or other entities, all with the intent of obscuring the source of the funds.
Through these intricate schemes, the criminals manage to distance themselves from their illegal origins, creating an illusion of legitimacy around their wealth. Each stage of this process reflects the lengths to which individuals will go to cloak their illicit gains in a veneer of respectability.
Integration and Extraction of Funds
In the intricate web of our economy, funds are intricately woven through various channels. Individuals and entities engage in a diverse array of activities to inject capital into the marketplace. They invest in real estate ventures, embark on business projects, acquire goods and services, and even hire fictitious employees, among other strategies. Each of these avenues serves as a means to integrate funds, transforming them into active components of the economic landscape.
The Rise of P2P Payment Fraud
In recent times, the landscape of peer-to-peer (P2P) payments has witnessed explosive growth, fueled by popular cash applications such as PayPal, Venmo, Google Pay, Apple Pay, Zelle, and Alipay. Unfortunately, this surge has created a fertile ground for fraudulent activities. Unscrupulous individuals have discovered ways to exploit the limited data and minimal insights that these digital payment platforms provide for fraud prevention.
These fraudsters engage in deceptive practices, such as selling non-existent products or utilising stolen credit cards to set up new P2P accounts. This allows them to execute unauthorised transactions with ease. According to Forbes, the estimated losses due to P2P fraud soared to a staggering $1.7 billion in 2022, marking a shocking 90% increase compared to the previous year.
The Mechanics of Application Fraud
As we delve deeper into the realm of financial deceit, we encounter application fraud—a practice where criminals take advantage of stolen or fabricated identification to apply for loans or credit lines. These perpetrators employ varied and cunning methods.
One common tactic is the Gradual Credit Card Scheme. Here, a fraudster applies for a credit card, patiently building their credit score over several months or even years. Once they’ve established a solid history, they max out the card without any intention of repayment, leaving financial institutions in the lurch.
Another alarming method is Loan Stacking. In this scenario, criminals submit numerous loan or credit applications simultaneously across various financial institutions, often employing automated bots and virtual machines. They vanish with the funds before anyone catches on to their scheme.
Moreover, synthetic identities are erupting. For third-party application fraud, fraudsters cleverly blend accurate and fabricated information to create identities that don’t exist in reality. In contrast, first-party fraud involves using genuine personal details but embellishing them with false information, such as a fictitious address or inflated income figures.
A Surge in Loan Fraud
Loan fraud is a specific variant of application fraud that has seen a troubling rise in recent years. A report from CoreLogic highlighted that nearly 1% of mortgage applications were fraudulent in the second quarter of 2022—equating to 1 in every 131 applications.
This form of deceit encompasses various practices, including mortgage fraud, loan scams, and payday fraud, all of which are characterised by criminals leveraging personal data to secure loans illegitimately.
The alarming increase in loan fraud can be partially attributed to the burgeoning popularity of online lenders who often bypass rigorous background checks and scrutiny. As this trend continues to unfold, it raises significant concerns about the integrity and security of financial systems in an ever-evolving digital landscape.
