Form jacking: The Silent Threat to MSMEs

The digital landscape has transformed businesses’ operations, particularly for Micro, Small, and Medium Enterprises (MSMEs). While e-commerce has opened new avenues for growth, it has also introduced a host of digital threats. Form jacking stands out as a particularly insidious attack vector. Business leaders can significantly enhance their organisation’s cybersecurity posture by understanding the nature of form jacking, its risks to MSMEs, and the strategies to mitigate it.

Understanding Formjacking

Formjacking is a sophisticated cybercrime where malicious code is injected into e-commerce websites to rob payment card details. Attackers target online forms, such as checkout pages, to capture sensitive information as customers enter. Once compromised, this data is transmitted to the attacker, leaving businesses and customers vulnerable to financial loss and reputational damage.

How Does Formjacking Work?

Formjacking attacks typically involve the following steps:

Website Compromise: Attackers exploit vulnerabilities in a website’s content management system (CMS) or e-commerce platform to inject malicious code.
Code Injection: The injected code modifies the checkout page, creating hidden fields or overlaying fake forms to capture payment card details.
Data Exfiltration: The stolen data is transmitted to a remote server controlled by the attacker.
Data Abuse: The stolen information is utilised for shady transactions or sold on the dark web.

The Impact of Formjacking on MSMEs

The consequences of a formjacking attack can be devastating for MSMEs. Beyond the immediate financial loss due to fraudulent transactions, the attack can erode customer trust, damage brand reputation, and lead to legal liabilities. Moreover, the costs associated with fraud investigations, chargebacks, and regulatory compliance can be substantial.

Key Impacts:

Financial Loss: Direct monetary losses due to fraudulent transactions, chargebacks, and fines.
Customer Loss: Damage to customer trust and loyalty, leading to decreased sales.
Reputational Damage: Negative publicity and loss of credibility in the market.
Legal and Regulatory Risks: Compliance breaches and potential legal actions.
Operational Disruption: Business interruptions due to investigations and remediation efforts.

The MSME Challenge

MSMEs often face unique challenges in combating cyber threats:

Limited Resources: Smaller budgets and fewer IT personnel.
Lack of Awareness: There is a need for more understanding of cyber risks.
Focus on Growth: Prioritisation of business expansion over security.

These factors make MSMEs particularly attractive targets for cybercriminals.

Defending Against Formjacking

A robust cybersecurity strategy is vital for protecting MSMEs from formjacking attacks. Here are critical defensive measures:

Web Application Firewalls (WAFs)

WAFs are indispensable tools for detecting and preventing formjacking attacks. By examining incoming traffic, WAFs can identify malicious code, block suspicious requests, and protect sensitive data.

Emerging Threats: Magecart and Skimmers

While formjacking remains a significant threat, the evolving cybercrime landscape has introduced new challenges for MSMEs. Two prominent examples are Magecart and Skimmers.

Magecart: The Silent Threat

Magecart is a collective term for cybercrime groups specialising in injecting malicious JavaScript code into e-commerce websites. Similar to form jacking, Magecart attacks aim to steal payment card information. However, they often employ more sophisticated techniques to evade detection.

How Magecart Works

Magecart attacks typically involve:

Skimming JavaScript code: Attackers inject malicious JavaScript code into the website’s source code.
Data Capture: The injected code captures payment card information as customers enter it.
Exfiltration: Stolen data is transmitted to attacker-controlled servers.

Impact on MSMEs

Magecart attacks can have severe consequences for MSMEs:

Financial Loss: Direct monetary losses due to fraudulent transactions.
Customer Churn: Loss of customer trust and loyalty.
Brand Reputation Damage: Negative publicity and impact on customer acquisition.
PCI DSS Compliance Issues: Non-compliance can lead to fines and penalties.

Skimmers: The Physical Threat

Skimmers are physical devices that capture payment card information when a card is swiped. While primarily associated with physical point-of-sale (POS) terminals, they can also be installed on online payment portals.

How Skimmers Work

Skimmers are typically installed on top of legitimate card readers, capturing card data as it is swiped. The stolen information is then transmitted to the attacker.

Impact on MSMEs

Skimmers can impact MSMEs in the following ways:

Financial Loss: Direct monetary losses due to fraudulent transactions.
Customer Churn: Loss of customer trust and loyalty.
Brand Reputation Damage: Negative publicity and impact on customer acquisition.
