What data sources are required to detect Malvertising (T1583.008)?

Detecting Malvertising requires the following data sources: Process: Process Creation, Microsoft Defender for Endpoint.

What severity and confidence is the T1583.008 detection?

The T1583.008 detection is rated high severity with medium confidence.

What are common false positives for T1583.008?

Common false positives for T1583.008 include: Browser-based enterprise software portals that use ClickOnce deployment, legitimately spawning msiexec.exe or setup.exe from the browser for internal application installation; IT administrators downloading and immediately running legitimate signed tools from vendor sites (e.g., Sysinternals, vendor agent MSIs, driver installers); Software update helpers where the browser opens a downloaded updater that spawns cmd.exe or PowerShell as part of a legitimate update workflow.

Detect Malvertising in IBM QRadar

Adversaries may purchase online advertisements to distribute malware to victims. Ads can be positioned prominently in search results or on popular websites, exploiting user trust in those platforms. Malvertising campaigns frequently spoof legitimate software vendors, tricking users into downloading trojanized installer packages. Because the adversary's infrastructure purchase occurs entirely outside the victim environment, detection must pivot to observable victim-side indicators: browsers spawning unexpected child processes, executable file downloads staged in user-writable directories, and drive-by script execution patterns consistent with clicking a malicious ad.

high severity medium confidence

AQL query for IBM QRadar correlating Windows Sysmon EventID 1 (Process Create) and Security EventID 4688 (New Process) to identify browsers spawning LOLBin or interpreter child processes. A multi-factor suspicion score is computed inline using CASE expressions matching download paths, network URLs, encoded-command tokens, and silent-install flags — mirroring the reference SPL scoring logic. Results are ordered by suspicion score descending for analyst triage.

False Positives & Tuning

Corporate patch management solutions that trigger browser-based authentication portals and subsequently call msiexec.exe or cmd.exe to apply updates silently (/quiet).
Internal web applications that launch helper executables via browser protocol handlers (e.g., custom URI schemes), producing a browser→child-process chain with no malicious intent.
Security awareness training platforms that simulate phishing/malvertising behavior in a controlled sandbox, generating real process-create events with matching parent-child patterns.

Testing Methodology

Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.

Test 1Simulate Browser Spawning PowerShell (Malvertising Drive-by Pattern)
Expected signal: Sysmon Event ID 1: Process Create with Image=powershell.exe, ParentImage=cmd.exe, CommandLine containing '-WindowStyle Hidden'. Sysmon Event ID 11: File Create for malv-test.txt in Temp. Security Event ID 4688 (if command line auditing enabled). PowerShell ScriptBlock Log Event ID 4104 showing Write-Output command.
Test 2Stage and Execute Trojanized Installer from Downloads Folder
Expected signal: Sysmon Event ID 11: File Create for 7zip-2400-x64.exe in the Downloads folder. Sysmon Event ID 1: Process Create with Image path inside the Downloads folder — anomalous for any legitimate software. Security Event ID 4688 if command line auditing is enabled.
Test 3HTA Drive-by Execution Simulating Malvertising Redirect
Expected signal: Sysmon Event ID 1: Process Create for mshta.exe with TargetFilename in Temp path. Sysmon Event ID 11: File Create for hta-atomic.txt. Security Event ID 4688 for mshta.exe execution. If launched from a browser parent, the main detection fires on mshta.exe as a SuspiciousChild with DownloadPath=1.
Test 4PowerShell Download Cradle Spawned from Browser Context (Simulated Raspberry Robin Pattern)
Expected signal: Sysmon Event ID 1: Process Create for powershell.exe, ParentImage=cmd.exe, CommandLine containing 'Net.WebClient' and 'DownloadString'. Sysmon Event ID 3: Network connection attempt to 127.0.0.1:18080 (connection refused, but event still fires). PowerShell ScriptBlock Log Event ID 4104 showing the download cradle code.
