What it is
A backdoor that Google Threat Intelligence Group and Mandiant name SHINYROAD, installed in the 2026 AOMEI Backupper update tampering.
What it does
It hides in the files of signed Radmin software, decrypts its code in memory and can run commands and new code from its operators.
Who uses it
Attributed by Google Threat Intelligence Group and Mandiant to a cluster they track as UNC7017. No government has named an actor in the sources we opened.
How it gets in
CROSSROAD installs it after a computer fetches a tampered AOMEI Backupper update.
What to do first
Check for the scheduled task RadminComponentRuntime and for an unsigned library loaded by the Radmin launcher.

What it does

SHINYROAD is the third stage of the chain that begins with the CROSSROAD downloader. Google and Mandiant say it abuses signed Radmin software: the signed Radmin launcher loads a harmful library placed next to it, a form of DLL hijacking.

That library registers a component that loads the real implant. ManageEngine says the implant decrypts its code in memory and runs it with an embedded interpreter. It describes a self-updating agent that talks to one fixed address over a plain network connection and can run commands and new code.

ManageEngine did not see a live session, because the control server did not answer during its tests. Its report calls what it saw a floor, not a ceiling. Read the AOMEI Backupper incident for the full story.

How it spreads

SHINYROAD is not spread on its own. CROSSROAD installs it after a computer fetched a tampered AOMEI Backupper update. A scheduled task then starts the Radmin launcher every three hours, which loads the harmful library.

How an infection runs

The order of steps in a typical infection, as the sources describe it.

  1. Task runs

    A scheduled task starts the signed Radmin launcher every three hours.[1, 2]

  2. Library loaded

    The launcher loads a harmful library placed beside it, found by search order.[1, 2]

  3. Component registered

    The library registers a component that runs inside a signed Windows host process.[2]

  4. Code decrypted

    The implant decrypts its code in memory and runs it with an embedded interpreter.[1, 2]

  5. Contact home

    The agent connects out to one fixed address, runs commands and can receive new code.[2]

Timeline

  1. 16 July 2026

    Caught live

    ManageEngine's monitor sees the package change and revert within minutes.[2]

  2. Mid-July 2026

    Later tooling

    Google and Mandiant see another remote access tool, disguised as PDF software, used in the same campaign.[1]

  3. 15 and 16 October 2026

    Reports published

    Google and ManageEngine publish their findings.[1, 2]

Detection and defense

  1. Find the task

    Search for a scheduled task named RadminComponentRuntime.[1]

    Counters: T1053

  2. Check Radmin installs

    Look for Radmin software that nobody installed and for an unsigned library next to its launcher.[1, 2]

    Counters: T1574.001

  3. Watch outbound connections

    ManageEngine suggests alerting on a connection to a high port with no earlier name lookup.[2]

  4. Keep the evidence

    Preserve staging folders and correlate alert times with network logs.[1, 2]

  5. Know what is published

    We found no government advisory with detection signatures for SHINYROAD.[1, 2]
