A researcher has conducted a detailed analysis of the two pieces of Mac malware delivered recently by threat actors to cryptocurrency exchanges via two Firefox vulnerabilities. The macOS malware delivered to Coinbase and other organizations involved with cryptocurrencies has been analyzed in detail by Patrick Wardle, a researcher who specializes in the security of Apple products. Netwire, also known as Wirenet, is a piece of malware that emerged in 2012, designed for stealing passwords from Linux and OS X systems. According to Wardle, the malware involved in the recent Firefox zero-day attacks is designed to run on many versions of the Apple operating system, including all the way back to OS X 10.5 Leopard, released in 2007. Furthermore, Apple’s XProtect system can detect the Netwire sample based on a Yara signature added by the company in 2016 for an older version of the malware. Security researcher Vitali Kremez has found some links to previous campaigns, along with some evidence suggesting that Windows malware may have also been delivered in the recent Firefox attacks.
