Rewterz Threat Alert – Nanocore RAT – Active IOCs

Severity

Analysis Summary

Nanocore is a high-risk RAT (remote access tool) that provides attackers with user information like device name and OS. Malicious activities like hijacking webcam and microphone, manipulating confidential files, and stealing login credentials are performed by this malware. The nanocore attack starts with a phishing attempt where a victim unwittingly downloads or clicks on an attachment, the trojan is uploaded on the device, business-critical data and financial information of the victim are stolen through the keylogger, and the information is moved to another server that is owned by the hackers (initiating ransomware).
