MacOS Infostealer Variant Evades Detection Systems

New String Encryption Technique Used to Dupe Detection Systems

A variant of the Banshee macOS infostealer has been discovered to be using a new string encryption technique copied from Apple’s in-house algorithm to evade detection systems. This new variant was caught by Check Point researchers after two months of successful evasion.

Threat Actors’ Distribution Methods

The threat actors behind the Banshee variant distributed it using phishing websites and fake GitHub repositories, often impersonating popular software such as Google Chrome, Telegram, and TradingView. This highlights the importance of being cautious when downloading software and verifying the authenticity of websites and repositories.

Security Expert’s Concerns

Cybersecurity expert Ngoc Bui from Menlo Security expressed concerns about the new variant, stating that it highlights a significant gap in Mac security. “While companies are increasingly adopting Apple ecosystems, the security tools haven’t kept pace,” he said. “Even leading EDR solutions have limitations on Macs, leaving organizations with significant blind spots. We need a multi-layered approach to security, including more trained hunters on Mac environments.”

Implications for Mac Security

The discovery of this new variant underscores the need for improved security measures on Macs. With the increasing adoption of Apple ecosystems, it is essential to ensure that security tools are up-to-date and effective in detecting and preventing threats. The limitations of EDR solutions on Macs highlight the importance of a multi-layered approach to security, including human expertise and advanced technologies.

Conclusion

The discovery of the new Banshee variant highlights the ongoing threat posed by macOS infostealers. The use of new string encryption techniques to evade detection systems underscores the need for continued innovation and improvement in security measures. As the adoption of Apple ecosystems continues to grow, it is essential to prioritize Mac security and ensure that organizations are equipped to detect and prevent threats.
