Cerberus
Table of Contents
Overview
Cerberus is a highly sophisticated Android banking Trojan that emerged in 2019, initially operating under a Malware-as-a-Service (MaaS) model on underground forums. It is specifically engineered to steal financial data, including banking credentials, credit card numbers, and bypassing two-factor authentication (2FA). Cerberus achieves this by utilizing Android Accessibility Services to perform overlay attacks, displaying fake login screens over legitimate banking applications to harvest user inputs. Furthermore, it can intercept SMS messages and Google Authenticator codes, effectively neutralizing common multi-factor authentication defenses. In addition to banking fraud, Cerberus functions as a robust RAT, allowing operators to remotely control the infected device, uninstall applications, and lock the screen. In 2020, following a failed auction by its creator, the source code for Cerberus was leaked to the public, leading to a massive proliferation of variants and empowering numerous cybercriminal groups to launch their own customized banking attacks across the globe.

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:
Tier 1 Primitive Artifact Rule (Fast Triage)
Matches raw strings and file markers. Vulnerable to binary repacking and simple obfuscation.
rule MALWARE_WIN_CERBERUS_T1_ARTIFACT {
meta:
description = "Tier 1 Primitive Artifact: Raw string matches for Cerberus"
tier = "T1 - Primitive Artifact"
confidence = "Low-Medium (Fast Triage)"
author = "SystemHelpdesk Threat Research Desk"
date = "2026-10-14"
strings:
$s1 = "cerberus" ascii wide nocase
$s2 = "android.cerberus" ascii wide nocase
$s3 = "cerberus banking trojan" 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.
- Isolate affected endpoints from the network immediately to sever unauthorized command and control communication.
- Identify and terminate active Cerberus binaries and associated parent-child process chains.
- Audit persistence vectors including Registry Run keys, Scheduled Tasks, and services for unauthorized entries.
- Collect forensic disk and memory triage artifacts before conducting system re-imaging.
What to Avoid
Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.
- Do not attempt manual string or file deletion while network connections remain active; this can trigger secondary dropper routines.
- Avoid restoring from backups without verifying that the backup snapshot predates initial Cerberus installation.
