Shiz

Overview

Trojan-Banker:Win32/Shiz is a notorious, historically significant Russian banking trojan that served as a critical evolutionary link connecting early Zeus and Gozi implementations with subsequent crimeware families including Carberp, Vawtrak (Neverquest), and Snifula. First detected around 2010, Shiz specialized in Man-in-the-Browser (MitB) financial theft, intercepting online banking credentials, digital security certificates, and transaction authentication codes from major commercial banks across Russia, Europe, and the United States. Shiz achieves stealth by injecting into svchost.exe, explorer.exe, and web browsers, hooking Windows networking APIs (wininet.dll, ws2_32.dll, and nss3.dll) to intercept plaintext HTTP and HTTPS sessions prior to encryption. This allows the trojan to dynamically alter banking DOM interfaces, presenting deceptive form fields to harvest one-time passwords (OTP). Shiz pioneered advanced sandbox evasion routines, including encrypted registry storage for configuration files, virtual machine detection, and dynamic peer-assisted C2 communication using AES and RC4 cryptography. Multiple criminal syndicates operating Shiz were dismantled during Russian Ministry of Internal Affairs (MVD) investigations between 2012 and 2014.

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.
• T1185: Enforce strong MFA and use browser isolation or hardened browsers for sensitive financial or administrative portals to defeat session hijacking.

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-2010-2568 — In-depth exploitation analysis and catalog intelligence (NIST NVD ↗).
• CVE-2012-0158 — 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_SHIZ_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Shiz"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "shiz" ascii wide nocase
        $s2 = "shiz" ascii wide nocase
        $s3 = "win32.shiz" ascii wide nocase
        $s4 = "trojan-banker.win32.shiz" ascii wide nocase
        $s5 = "shiz.a" ascii wide nocase
        $s6 = "shiz.b" ascii wide nocase
        $s7 = "shiz_banker" ascii wide nocase
    condition:

Containment & Response Steps

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

1. Terminate injected browser processes and isolate affected corporate financial workstations.
2. Revoke compromised banking session cookies and reset all financial portal credentials.
3. Inspect system memory for unlinked DLL injection artifacts in wininet.dll and ws2_32.dll.
4. Deploy endpoint detection agents capable of identifying API hooking in user-mode browser memory.

What to Avoid

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

1. Do not input one-time passwords or bank authorization tokens into unexpected browser verification screens.
2. Avoid accessing corporate banking portals from unmanaged workstations lacking EDR protection.
3. Never allow execution of untrusted macros in incoming email attachments.
