Tibia

Overview

PWS:Win32/Tibia (often referred to as a 'Tibia Cam' or Tibia Stealer) is a highly specific Password Stealer (PWS) designed exclusively to target players of the classic MMORPG, **Tibia**. This malware family demonstrates how threat actors create specialized tools to compromise specific online communities in order to steal virtual assets, in-game currency, and high-level accounts for real-world financial gain.

Understanding Tibia Stealers
To an end-user, a Tibia stealer is completely invisible, masquerading as a legitimate, highly sought-after game modification or utility. The victim only realizes they are infected when they log into the game and find their character stripped of all valuable items. For a security analyst, this malware highlights the risk of users downloading unverified software to gain an advantage in online ecosystems.

Execution and Theft Mechanics
Tibia stealers are heavily distributed via social engineering within the game's community forums and fan sites. They are typically disguised as 'Tibia Cam' software (used to record gameplay), automated bots (for farming experience), or 'light hacks' (`T1204.002`). Upon execution, the malware establishes persistence (`T1547.001`). Its core function is highly specialized: it monitors the system for the execution of the official `Tibia.exe` client. When the user launches the game, the malware either injects a keylogger specifically to capture the account name and password entered at the login screen (`T1056.001`), or it uses API hooking to read the credentials directly from the game client's memory space before they are encrypted and sent to the game server. The stolen credentials are then immediately emailed or sent via HTTP POST to the attacker (`T1048.003`).

Indicators of Compromise & Impact
The impact is the total loss of the victim's Tibia account and associated virtual wealth. Host-based IoCs include EDR alerts for suspicious processes attempting to read the memory of or inject into `Tibia.exe`. The presence of unauthorized 'Tibia Cam' or botting executables in the user's download directory is a primary indicator. Network IoCs include anomalous outbound SMTP or HTTP traffic containing account strings immediately following a game launch.

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.

MITRE D3FEND™ Defensive Countermeasures

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_TIBIA_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Tibia"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "tibia" 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. Isolate the endpoint and run a full anti-malware scan to identify and remove the specialized game stealer.
2. Advise the user to immediately log into their Tibia account from a known-clean machine and change their password.
3. Advise the user to enable two-factor authentication (2FA) if the game publisher offers it.
4. Locate and permanently delete the fake 'Tibia Cam' or bot installer to prevent reinfection.

What to Avoid

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

1. Do not allow users to download unauthorized third-party game modifications on corporate hardware, as they are a primary vector for credential stealers.
2. Avoid assuming that because the malware targets a game, it cannot be repurposed to steal corporate credentials if the user recycles passwords.
