Rewterz Threat Alert – Nanocore – IoCs

November 27, 2020

Severity

Medium

Analysis Summary

NanoCore is a remote access tool (RAT). In most cases, this malware is distributed using spam email campaigns. Criminals send thousands of deceptive emails that contain malicious attachments. Once opened, these files immediately infect computers with malware such as NanoCore. The presence of this malware can result into data exfiltration, since the malware distributor gains remote access to the infected system. The malware is also capable of disabling some tools, stealing credentials and sensitive information.

Impact

  • Credential Theft
  • Unauthorized Access
  • Theft of Sensitive Information
