What Are the Common Types of Fraud?

Let’s delve deeper into each type of fraud, providing a comprehensive overview of each:

Identity Theft: Identity theft is the malicious acquisition and use of an individual’s personal information, typically for financial gain.

How it works: Fraudsters employ various tactics, from phishing emails to data breaches, to gather personal details. Once acquired, this information can be used to impersonate the victim, open new accounts, or make unauthorized transactions.

Example: John discovers that someone has opened multiple credit cards in his name, racking up thousands in debt. Upon investigation, he realizes his personal details were compromised during a major data breach at a retail store where he shopped.

Credit Card Fraud:

Credit card fraud encompasses unauthorized transactions made using someone else’s credit card or card details.

How it works: Fraudsters can obtain credit card details through methods like skimming devices, phishing scams, or database breaches. Once they have the details, they can make unauthorized purchases or even sell the information on the dark web.

Example: Jane receives her monthly bank statement and notices several high-value transactions from overseas vendors she doesn’t recognize. It turns out her card details were skimmed at a local ATM and used for these unauthorized purchases.


  Phishing is a deceptive technique used by fraudsters to trick individuals into revealing sensitive information, such as passwords or credit card numbers.

How it works: Typically, fraudsters send emails or messages that appear to be from legitimate organizations, urging recipients to click on links or download attachments. These links lead to fake websites designed to capture the victim’s information.

Example: Bob receives an email that appears to be from his bank, asking him to verify his account details due to suspicious activity. The email looks authentic, but it’s a phishing attempt. When Bob enters his details on the linked page, fraudsters capture his login credentials.

Account Takeover:

  This refers to unauthorized access and control of a user’s account, often for malicious purposes.

How it works: Fraudsters can obtain login credentials through phishing, malware, or even brute-force attacks. Once inside, they can make unauthorized transactions, change account details, or lock the genuine user out.

Example: Alice receives a notification that her email password has been changed, a change she didn’t authorize. She later discovers several unauthorized purchases made from her linked e-commerce accounts.

Payment Fraud: Payment fraud involves any transaction where there’s an intent to deceive the recipient or platform to gain goods or services without proper payment.This can involve using stolen credit card details, counterfeit checks, or manipulating transaction details to avoid full payment.

Example: A fraudster purchases an expensive gadget online using a stolen credit card. The genuine cardholder disputes the charge when they notice the unauthorized transaction on their statement.

Mobile Fraud: Mobile fraud targets vulnerabilities in mobile platforms and applications, leading to unauthorized access or transactions.

Fraudsters can exploit weak security protocols in mobile apps, use SMS phishing, or even create fake apps to capture user information.

For example, Carla downloads a mobile banking app from an unofficial source. The app, which is malicious, captures her login details and allows fraudsters to access her bank account.

E-commerce Fraud: The fraud relates to deceptive practices in online shopping environments. This can involve using stolen credit card details for purchases, creating fake product listings, or scamming buyers with counterfeit items.

For example, David orders a high-end camera from an online marketplace at a significantly reduced price. Upon delivery, he realizes the product is a cheap knock-off.

Application Fraud: It involves providing false or exaggerated information when applying for financial products or services.Fraudsters might create entirely fake identities or modify certain details to improve their chances of approval or to obtain better terms.

For example, Emma applies for a mortgage, inflating her income on the application form. The bank, relying on this false information, approves a loan amount that Emma wouldn’t qualify for with her actual income.

Internal Fraud:It originates from within an organization, often perpetrated by employees or insiders.Individuals with access to systems or sensitive information misuse their privileges for personal gain, either by siphoning funds, manipulating records, or stealing data.

For example, Frank, an accountant at a firm, alters financial records to divert company funds into his personal account.

Money Laundering: Money laundering involves making illegally-gained proceeds appear legal by moving them through a complex sequence of banking transfers or commercial activities.

By passing money through various transactions and accounts, the origins of these funds become obscured, making them harder to trace back to their illicit sources.

Example: Gina operates an illegal gambling ring. To legitimize her earnings, she invests the money in a series of businesses, making the funds appear as legitimate revenue.

Affiliate Fraud: Affiliate fraud involves generating fake actions or leads in affiliate marketing programs to claim undeserved commissions.Fraudsters might use bots to simulate website clicks, fake user sign-ups, or generate bogus sales to claim commission payouts.

For example, Harry sets up a website and enrolls in an affiliate marketing program. He then uses bots to generate fake traffic and clicks, earning commissions for non-existent sales.

Return Fraud: Return fraud involves deceitfully returning goods to claim a refund or benefit.

Customers might purchase an item, use it, and then return it as if it was unused. Alternatively, they might return a counterfeit item in place of the genuine product.

For example, Irene buys a designer handbag, uses it for a week, and then returns it claiming it was never used. The store, unable to verify the claim, processes the refund.

Bonus Abuse:Bonus abuse involves the exploitation of promotional offers, typically in online gaming or e-commerce platforms.Users might create multiple accounts, use loopholes, or employ other deceptive tactics to claim bonuses or rewards multiple times.

For example, Jack discovers a loophole in an online casino’s sign-up bonus system. He repeatedly signs up using different details, claiming the bonus multiple times without genuinely engaging with the platform.

Friendly Fraud: It involves legitimate purchases that are later disputed by the customer, often without proper justification.

After making a purchase, a customer might dispute the charge with their credit card provider, falsely claiming they didn’t receive the item or didn’t authorize the purchase.

For example, Karen orders a set of headphones online. After receiving and using them, she contacts her credit card company to dispute the charge, falsely claiming the product was never delivered.

Denial of Service (DoS): A DoS attack aims to disrupt a service or network, making it unavailable to its intended users.

Attackers flood the target with superfluous requests, overwhelming the system and causing it to crash or become unresponsive.

For example, an online retailer’s website is bombarded with traffic during a peak sale period. The site crashes, preventing genuine customers from making purchases. It’s later discovered that this traffic surge was a deliberate DoS attack.

Malware: Malware, or malicious software, is designed to damage, disrupt, or gain unauthorized access to computer systems.Malware can be introduced to systems via malicious email attachments, software downloads, or compromised websites. Once installed, it can steal data, monitor user activities, or cause system malfunctions.

For example, Laura receives an email with an attachment labeled “Invoice.” She opens it, unknowingly installing malware that begins encrypting her files, demanding a ransom for their release.

Phishing: Phishing is a method employed by fraudsters to deceive individuals into providing sensitive information by masquerading as a trustworthy entity.

Typically conducted via email, fraudsters send messages Phishing email that appear to be from legitimate sources, urging recipients to provide personal details or click on malicious links.

For example, Mike receives an email, seemingly from his bank, requesting immediate action due to suspicious account activity. The email contains a link to a fake banking site where Mike is prompted to enter his login details, which are then captured by fraudsters.

Ransomware: Ransomware is a type of malicious software that restricts access to a computer system or data, demanding a ransom be paid to the attacker for the restriction to be removed.

Once a system is infected, usually through phishing or malicious downloads, the ransomware encrypts the user’s files or locks the system. A ransom note is then displayed, demanding payment in exchange for the decryption key.

For example, Nancy’s computer suddenly displays a message stating all her files have been encrypted. The message demands payment in cryptocurrency to unlock her data. She realises her system has been infected with ransomware after opening an email attachment from an unknown sender.
