A variant of the infamous Dridex banking malware has set its sights on Apple's macOS operating system using a previously undocumented infection method, according to latest research. Previous Dridex campaigns targeting Windows have leveraged macro-enabled Microsoft Excel documents sent via phishing emails to deploy the payload.
