Data Skimming Bots
Understanding Data Skimming Bots: A Cybersecurity Threat to Online Transactions
Data skimming bots, often referred to in the context of cybersecurity, are malicious software applications designed to steal sensitive information, particularly payment card details, from websites. So from the Shadow of a Doorway, consider this breakdown of what they are, how they operate, and how to protect against them.
What Are Data Skimming Bots?
Data skimming bots are a form of malware that cybercriminals use to capture sensitive data entered into website forms ... most commonly payment information during online transactions.
This process is often called e-skimming or digital skimming.
How Do They Work?
Injection of Malicious Code
These bots insert harmful JavaScript into a website’s payment pages. The malicious code is typically hidden in compromised third-party scripts or plugins used for website functionalities like analytics or chat services.
Real-Time Data Capture
Once injected, the script silently records data as users enter their payment details, with no visible disruption to the user experience.
Data Transmission
The stolen data is sent to servers controlled by attackers. In some cases, even legitimate services, like Telegram, are exploited for data exfiltration.
Techniques Used by Cybercriminals
A method where attackers compromise e-commerce sites, inserting skimming scripts into checkout pages. Magecart groups have targeted numerous high-profile brands.
This technique involves injecting malicious scripts into legitimate website forms to steal data.
The Impact of Data Skimming Bots
Financial Losses
Businesses lose millions in revenue, including fines under regulations like GDPR and CCPA.
Reputational Damage
Breaches erode customer trust and can lead to significant brand damage.
Data Misuse
Stolen payment details often fuel unauthorised transactions or are sold on the dark web.
How to Prevent and Detect Data Skimming Bots
Regular Monitoring
Frequently scan your website for unauthorised changes to code.
Security Software
Implement solutions such as web application firewalls (WAFs), CAPTCHA, and bot management platforms to detect and mitigate threats.
Third-Party Script Management
Ensure that all scripts are from trusted sources and keep them updated to reduce vulnerabilities.
Real-World Cases: Lessons from High-Profile Attacks
Boost Your Online Security Awareness
Notable examples, such as the British Airways breach, illustrate the widespread impact of Magecart skimmers. Millions of customers’ payment data were compromised, resulting in financial penalties and lasting reputational damage.
Stay informed and proactive to safeguard your business and customers from data skimming attacks.
