Study of 85 Crypto Wallet Extensions Finds Address Leaks and Cross-Site Tracking Risks

The Hacker News

Overview

A recent study by researchers at KU Leuven examined 85 popular crypto wallet extensions and discovered that many of them leak sensitive information, allowing for user tracking. The way these wallets communicate with websites and blockchain servers can inadvertently link different wallet addresses belonging to the same user, making it easier for outsiders to track their online activities. This poses a significant risk to user privacy, particularly for those who rely on these wallets for cryptocurrency transactions. The findings raise concerns about the security measures in place for these extensions and highlight the need for better user protection against potential tracking and data leaks.

Key Takeaways

  • Affected Systems: 85 crypto wallet browser extensions
  • Action Required: Users should review their wallet extensions for privacy features, consider using wallets with better security practices, and stay informed about updates from wallet developers.
  • Timeline: Newly disclosed

Original Article Summary

Researchers at KU Leuven tested 85 of the most popular crypto wallets that run as browser extensions and found that the wallets themselves leak enough to link and track the people using them. The way these wallets talk to websites and blockchain servers can tie a person's separate addresses together and let outsiders follow them from site to site. And on a site that already holds a name or

AI Speeds Up Malware Development, Not Its Success Rate: Analysis

SecurityWeek

A recent analysis by Palo Alto Networks' Unit 42 examined 405 malware samples that are linked to artificial intelligence. The findings revealed that while AI can accelerate the development of malware, it does not necessarily improve its success rate. Out of the analyzed samples, only 12 managed to reach production endpoints, which indicates that most AI-generated malware struggles to effectively infiltrate systems. This study is significant as it suggests that while cybercriminals may adopt AI to create malware more quickly, the effectiveness of these tools remains limited. Companies and security teams should continue to focus on traditional defenses as the majority of AI-linked malware is not successfully deployed.
