Babar

Overview

Trojan:Win32/Babar is a highly sophisticated, nation-state cyber-espionage implant attributed by international intelligence agencies and cybersecurity researchers to the 'Animal Farm' Advanced Persistent Threat (APT) group (extensively linked in Canadian Communications Security Establishment / CSEC classified slides published by Edward Snowden and Le Monde to the French Directorate-General for External Security / DGSE). First publicly analyzed in February 2015 by Citizen Lab and Cyphort, Babar was named after the beloved French cartoon elephant character, mirroring other malware in the campaign named after cartoon animals (such as Casper, Dino, and Bunny). Babar is an advanced surveillance weapon engineered for precise corporate and geopolitical intelligence collection. It features real-time audio interception capabilities targeting voice-over-IP (VoIP) conversations (specifically Skype, MSN, and Yahoo Messenger), persistent keystroke logging, desktop screen grabbing, clipboard harvesting, and targeted document exfiltration. Babar executes via sophisticated process injection into internet-facing applications (such as browsers and communication software), communicating with C2 servers using custom HTTP encryption to evade perimeter DPI inspection.

MITRE ATT&CK Techniques

Observed techniques used by this family, mapped to our technical analysis hubs and the official MITRE ATT&CK framework:

Tactical Mitigations

Based on the techniques used by this family, consider the following defensive strategies:

• T1056.001: Implement Endpoint Detection and Response (EDR) to monitor for suspicious API calls related to keystroke interception. Enforce Multi-Factor Authentication (MFA) to render stolen passwords useless.
• T1071.001: Implement web filtering and SSL/TLS inspection to detect malicious command and control (C2) traffic hiding in HTTP/HTTPS.
• T1113: Monitor for frequent or unauthorized screen captures or clipboard reads. Restrict background applications from accessing desktop APIs.

MITRE D3FEND™ Defensive Countermeasures

Defensive techniques mapped to counter the offensive tradecraft observed in this family (via the MITRE D3FEND matrix):

Exploited Vulnerabilities (CVEs)

This malware family is documented weaponizing the following common vulnerabilities and exposures:

• CVE-2014-0515 — In-depth exploitation analysis and catalog intelligence (NIST NVD ↗).
• CVE-2014-4114 — In-depth exploitation analysis and catalog intelligence (NIST NVD ↗).

Command & Control (C2) and Network Profile

How this family talks to its operators. C2 traffic can often identify a family even when its code and configuration are hard to analyse. Ports and patterns are historical and change between campaigns, so use them as hunting leads rather than block-only rules.

Indicators of Compromise

Public indicators drawn from CISA advisories and vendor reporting. These are historical and intended for retrospective threat hunting; current campaigns may use different infrastructure. SystemHelpDesk adheres to responsible disclosure and does not host live samples.

File hashes (SHA-256, sample)

Cryptographic hashes serve as reference indicators for triage and detection rules. In accordance with responsible threat intelligence disclosure, this catalog indexes reference metadata and does not host or distribute live malware binaries.

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:

rule MALWARE_WIN_BABAR_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Babar"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "babar" ascii wide nocase
        $s2 = "babar" ascii wide nocase
        $s3 = "trojan.babar" ascii wide nocase
        $s4 = "win32/babar" ascii wide nocase
        $s5 = "animal farm babar" ascii wide nocase
    condition:
        uint16(0) == 0x5a4d and any of them
}

Containment & Response Steps

Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.

1. Terminate injected VoIP client and web browser processes showing unauthorized audio hook libraries.
2. Deploy endpoint detection agents to identify audio device enumeration and API hooking in winmm.dll and dsound.dll.
3. Block outbound HTTP/HTTPS communication to known Animal Farm command domains.
4. Apply security patches for Microsoft Office and browser components to prevent watering-hole exploitation.

What to Avoid

Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.

1. Avoid discussing sensitive or classified matters over unencrypted consumer VoIP applications on untrusted networks.
2. Never ignore anomalous process injections into web browser or messaging binaries.
3. Do not allow unverified browser plugins or outdated multimedia software to execute on high-value executive laptops.
