Pony
Overview
Executive Summary
Pony (also widely known as Fareit) is a prolific, highly successful Information Stealer (InfoStealer) and botnet client. Active since roughly 2011, it is explicitly designed to rapidly harvest a vast array of credentials (passwords, cryptocurrency wallets, FTP logins) from infected systems and exfiltrate them to an attacker-controlled server. It is frequently used as a "first-stage" payload to steal credentials before downloading more destructive malware.Infection Vector and Technical Capabilities
Pony is primarily distributed via massive spam campaigns (malspam) utilizing malicious attachments or exploit kits. It is also commonly bundled with pirated software or keygens on P2P networks. Its technical focus is rapid credential extraction:- Broad Application Targeting: Pony contains specialized modules designed to decrypt and extract saved credentials from over 100 different applications. This includes major web browsers (Chrome, Firefox), FTP clients (FileZilla, WinSCP), email clients (Outlook, Thunderbird), and various cryptocurrency wallet files (wallet.dat).
- Rapid Exfiltration (Smash and Grab): Unlike a persistent RAT, Pony is often designed to execute, harvest all available credentials within seconds, upload them to the Command and Control (C2) server (often a compromised web server acting as a drop zone), and then optionally self-delete to evade analysis.
- Botnet Capabilities: While primarily a stealer, modern variants of Pony possess botnet functionality, allowing the C2 server to instruct the infected host to download and execute secondary payloads (like ransomware or banking trojans).
Threat Assessment
A Pony infection is a severe data breach. The immediate threat is the total compromise of corporate VPN credentials, webmail access, and FTP logins. Cybercriminals actively use Pony-stolen FTP credentials to deface legitimate websites or host further malware.Incident Response and Remediation
- Mandatory Credential Reset: The absolute highest priority is an immediate, global password reset for all accounts associated with the compromised user. Because Pony steals FTP and VPN credentials, these specific vectors must be secured instantly to prevent secondary breaches.
- MFA Enforcement: Ensure Multi-Factor Authentication (MFA) is strictly enforced across all external-facing corporate portals to neutralize the threat of the stolen passwords being reused.
- EDR Sweep: Utilize EDR to ensure the Pony executable has been removed and verify that it did not successfully download and execute a secondary payload before termination.

Frequently Asked Questions
What is Pony malware?
A credential stealer that also has downloader capabilities, harvesting stored passwords and other credentials.
Why is Pony so widespread?
The source code for Pony Loader 1.0 and 2.0 leaked online, letting many different actors use and modify it.
How is Pony related to Fareit?
The names are used for closely related malware sharing the same lineage and control panel.
How does Pony spread?
Through phishing and bundling with other malware.
How can I protect credentials from Pony?
Use a password manager and multi-factor authentication, and avoid suspicious attachments and downloads.
Where is the authoritative reference?
MITRE ATT&CK's Pony entry (S0453), linked on this page.
How do I remove the Pony Ransomware from Windows?
Manual removal of Pony 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 Pony a virus or a Ransomware?
Pony is classified as a Ransomware. Unlike traditional viruses that infect files, modern malware like Pony typically operates as a standalone payload designed to compromise systems, steal data, or deploy secondary stage implants.
What are the main symptoms of a Pony infection?
Symptoms of Pony 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.
