Mac malware-for-hire steals passwords and cryptocoins, sends “crime logs” via Telegram

by Paul Ducklin Researchers at dark web monitoring company Cyble recently wrote about a data-stealing-as-a-service toolkit that they found being advertised in an underground Telegram channel. One somewhat unusual aspect of this “service” (and in this context, we don’t mean that word in any sort of positive sense!) is that it was specifically built to help would-be cybercriminals target Mac users. The malware peddlers’ focus on Apple fans was clearly reflected in the name they…

APTs target MSP access to customer networks – Week in security with Tony Anscombe

The recent compromise of the networks of several companies via the abuse of a remote access tool used by MSPs exemplifies why state-aligned threat actors should be on the radars of IT service providers Managed service providers (MSPs) that don’t consider themselves targets for state-aligned threat actors may need to think again.
