Hackers Use NeedyMantis to Maintain Long-Term Access in Breached Networks

Microsoft identified a malware family called NeedyMantis used by attackers to maintain persistent access in already-compromised networks across telecommunications, universities, medical nonprofits, intergovernmental organizations, and government contractors. The malware has appeared in a limited number of targeted intrusions dating back at least several years.

Why it matters: Organizations in telecommunications, higher education, healthcare, government, and intergovernmental sectors should assess whether NeedyMantis persists in their networks, as attackers leverage it for long-term access after initial breaches.
