NanoCore RAT symptoms

The NanoCore RAT can be disguised as a secure and hard-to-find process. However, the PC system begins to show itself with typical general symptoms, such as:

  • The processor consumes more computer system resources.
  • PC often hangs and crashes.
  • Browsers are flooded with malicious pop-ups.
  • The random window starts working on its own, without any action from the user.
  • The page in the browser redirects the user to a malicious site.

How did the NanoCore RAT get into my PC?

NanoCore RAT is spread through spam and fake updates. Spam is a variety of malicious attachments (PDF files, MS Office documents and more). Users run the specified script by opening the extension, and they silently download and install the trojan.

Fake update programs start infecting systems by applying bugs and vulnerabilities to outdated software.

The main ways the emergence of the virus:

  • A program with a virus is downloaded and installed on the PC (free programs are often bundled with the NanoCore RAT).
  • The infected email is opened.

  • Peer-to-peer network.

The trojan program starts a chain reaction, in addition to installing other viruses.
