Is Your Credit Card Info In Danger: 2024 Analysis of E-Commerce Websites in Stealer Logs

The security of sensitive data in e-commerce, such as email addresses and associated accounts, is critical. As we investigate the vulnerabilities and cyber threats that pervade the digital space, it becomes essential to understand the consequences of such exposures.

Our analysis focuses on stealer logs from major e-commerce platforms, specifically data from the first quarter of 2024. This provides an overview of the most recent cybersecurity challenges and trends affecting the industry.

While many people share their email addresses online without considering the risks, this seemingly harmless action can lead to exploitation. Even reputable websites may experience security breaches at some point. Cybercriminals exploit such data by using infostealer malware to steal valuable information. This not only threatens individual users, but it also tarnishes platform reliability and poses serious risks to business owners, whose sensitive information may end up in stolen logs.

Stealer logs, or hidden repositories containing stolen data such as payment card information and user credentials, are a significant threat to the e-commerce industry. These logs are frequently traded on dark web forums, becoming tools for cybercriminals to commit fraud and breaches. These activities have a far-reaching impact, threatening the integrity of numerous e-commerce sites.

This blog post utilizes the SOCRadar Threat Hunting module, an effective resource that enables defenders to proactively detect and address threats found in stealer logs. Through this module, we build on earlier research and analyze the data to identify trends and offer valuable insights.

Stealer Logs Findings from E-Commerce Websites

Recent reviews of stealer logs from prominent e-commerce websites have unveiled a significant breach of user data in Q1 2024. This breach has compromised a massive 1,500,536 user records, sourced from 2,131 unique IP addresses, demonstrating the scale and potential impact of cybersecurity threats in the online shopping sector.

The detailed breakdown of the compromised data includes:

  • 179,712 unique IDs and email addresses: These represent the virtual identities of customers, making them prime targets for phishing attacks and identity fraud.
  • 180,444 passwords: The exposure of such a large number of passwords provides unauthorized access to personal accounts, heightening the risk of financial and data theft, and the presence of approximately 1,000 more unique passwords than IDs might suggest that some users have been compromised multiple times, which indicates the persistence of the fraudsters.
  • 7,837 hashes: Hashes are cryptographic representations of confidential information, which serve as the first line of defense for securing sensitive information. Their compromise suggests that advanced techniques may have been used, increasing the sophistication of the breach.
  • 2,454 credit card details: The direct financial risk is apparent, with thousands of users potentially facing fraudulent transactions.

This substantial breach highlights the vulnerabilities present in the e-commerce sector and underscores the need for heightened cybersecurity measures to protect consumer data.
