Antivirus protection is a baseline cost of doing business for the modern organization. At first, companies and governments only needed signature-based antivirus that tracked known malware. As fileless malware and exploits accelerated, next-gen antivirus that leveraged AI and behavioral analysis came on the scene to respond.

The 2018 Starwood Hotels breach is only the latest in a long line of high profile intrusions that hotels have faced. It’s notable primarily for how many customer records were exposed — 500 million worldwide according to parent company Marriott — and that the breach wasn’t discovered for four years.

A recent Ponemon report found that it takes an average of 197 days to discover a breach, and an average of 69 days to close it.

In this blog, we will present some findings on how NanoCore RAT 1.2.2.0 is actively being delivered in new and different ways that we discovered at Morphisec Labs in the last couple of months. Specifically, we will focus on the sophisticated fileless methods for delivering the RAT without touching the disk.

In August of 2019, just a month after our publication on a targeted BitPaymer/IEncrypt campaign, Morphisec identified a new and alarming evasion technique that the same adversaries adopted while targeting yet another enterprise in the automotive industry.
