Golroted
Table of Contents
Overview
Golroted (classified across antimalware engines under designations including Ransom:Win32/Golroted, Trojan-Ransom.Win32.Golroted, and Win32/Golroted) is a destructive crypto-ransomware family designed to lock enterprise and consumer Windows hosts. Propagated through malvertising redirects, phishing campaigns, and exploit kit droppers, Golroted terminates database processes, email services, and hypervisor components to ensure unhindered file access. It sweeps all available fixed, removable, and mapped network drives, encrypting critical business documents, databases, archives, and spreadsheets using AES-256 encryption wrapped with an asymmetric public key. Golroted executes vssadmin commands to purge Volume Shadow Copies, alters desktop wallpaper to display extortion demands, and deposits text ransom notes demanding cryptocurrency payments.

Tiered Detection Rules (Cisco CAIRN Model)
Modern threat detection requires multi-layered rule engineering. We classify detections into three operational tiers based on signal fidelity:
Tier 1 Primitive Artifact Rule (Fast Triage)
Matches raw strings and file markers. Vulnerable to binary repacking and simple obfuscation.
rule MALWARE_WIN_GOLROTED_T1_ARTIFACT {
meta:
description = "Tier 1 Primitive Artifact: Raw string matches for Golroted"
tier = "T1 - Primitive Artifact"
confidence = "Low-Medium (Fast Triage)"
author = "SystemHelpdesk Threat Research Desk"
date = "2026-10-14"
strings:
$s1 = "golroted" ascii wide nocase
$s2 = "ransom:win32/golroted" ascii wide nocase
$s3 = "trojan-ransom.win32.golroted" ascii wide nocase
$s4 = "win32/golroted" ascii wide nocase
$s5 = "ransom.golroted" ascii wide nocase
$s6 = "ransom:win32/golroted.a" ascii wide nocase
condition:
uint16(0) == 0x5a4d and any of them
}
Tier 2 Behavioral Context Rule (Process Chains & Sigma)
Tracks parent-child process anomalies and suspicious scripting telemetry. Resilient against file renames.

Containment & Response Steps
Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.
- Disconnect the affected host from network connections immediately to halt encryption across shared network drives.
- Kill active ransomware processes via Windows Task Manager or elevated PowerShell commands.
- Preserve forensic memory dumps and sample files for threat intelligence and hash matching.
- Block delivery vectors including malicious URLs and sender email domains.
- Restore encrypted files from air-gapped, immutable backup archives.
What to Avoid
Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.
- Do not pay the cryptocurrency ransom demand; it funds illicit cybercrime activities without guarantee of recovery.
- Do not reboot systems before securing volatile memory data.

Frequently Asked Questions
What is Ransom:Win32/Golroted?
Golroted is a crypto-ransomware family that encrypts Windows data with AES-256 and demands cryptocurrency ransom for decryption.
How does Golroted destroy local recovery options?
It executes vssadmin delete shadows /all /quiet to purge all Volume Shadow Copies.
What storage locations are targeted by Golroted?
It targets local fixed hard drives, external USB drives, and connected network file shares.
How is Golroted delivered to victim computers?
It is delivered through malicious malvertising redirects, phishing attachments, and exploit kits.
What is the recommended recovery response for Golroted?
Isolate the network, remove ransomware executables, and restore encrypted data from verified offline backups.
How do I remove the Golroted Ransomware from Windows?
Manual removal of Golroted is highly discouraged as it may leave persistence mechanisms intact. We recommend disconnecting the device from the internet and utilizing a professional incident response service or enterprise-grade EDR software to conduct a full forensic sweep.
Is Golroted a virus or a Ransomware?
Golroted is classified as a Ransomware. Unlike traditional viruses that infect files, modern malware like Golroted typically operates as a standalone payload designed to compromise systems, steal data, or deploy secondary stage implants.
What are the main symptoms of a Golroted infection?
Symptoms of Golroted can include unexpected system slowness, unauthorized outbound network traffic to unknown IP addresses, disabled security software, and suspicious background processes running from AppData or Temp directories.
