Researchers have discovered previously unknown Mac malware infecting a cryptocurrency exchange. It contains a full suite of capabilities, including the ability to steal private data and download and execute new malicious files.

Dubbed JokerSpy, the malware is written in the Python programming language and makes use of an open-source tool known as SwiftBelt, which is designed for legitimate security professionals to test their networks for vulnerabilities. JokerSpy first came to light earlier this month in this post from security firm Bitdefender.
