One such technique involves using \u003ccode\u003ewmic.exe\u003c/code\u003e with the \u003ccode\u003ecsproduct\u003c/code\u003e command to query system hardware models, vendors, and versions. This method, identified in various threat reports including those detailing Kuraystealer's operations since at least 2023, allows attackers to quickly gather crucial details about the underlying infrastructure of compromised systems. This information is vital for post-exploitation activities, enabling tailored attacks, further exploitation based on specific hardware vulnerabilities, or confirming the value of a compromised system before proceeding with data exfiltration. The reliance on a native, often whitelisted, tool like WMIC makes detection challenging for defenders without specific process command-line logging and robust correlation rules.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eInitial Access\u003c/strong\u003e: The victim downloads and executes a malicious payload, often disguised as legitimate software, initiating the Kuraystealer infection.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eExecution\u003c/strong\u003e: The Kuraystealer malware executes on the system, typically a .NET assembly, which then spawns child processes to perform its malicious activities.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eSystem Information Discovery\u003c/strong\u003e: The malware executes \u003ccode\u003ewmic.exe csproduct get name,vendor,version,identifyingnumber\u003c/code\u003e to gather detailed hardware model and vendor information about the compromised machine.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eAdditional Reconnaissance\u003c/strong\u003e: Kuraystealer continues to use \u003ccode\u003ewmic.exe\u003c/code\u003e and other built-in commands to collect further system details, such as information about the processor, BIOS, and baseboard, to build a comprehensive system profile.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eData Collection\u003c/strong\u003e: The infostealer actively searches for and collects sensitive data, including credentials from web browsers, cryptocurrency wallet files, and other specified personal information from the local system.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eData Staging and Exfiltration\u003c/strong\u003e: Collected data is typically compressed into an archive (e.g., ZIP) and then exfiltrated to attacker-controlled infrastructure, often leveraging platforms like Discord webhooks.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe successful execution of WMIC for reconnaissance provides attackers with valuable insights into the target system's hardware, enabling them to customize subsequent attacks or determine the value of the compromised host. In the context of infostealers like Kuraystealer, this reconnaissance precedes the theft of sensitive data, including credentials, browser history, and cryptocurrency wallet information. This leads to severe financial and reputational damage for victims, as critical information is exfiltrated and potentially sold or misused. While specific victim counts for this particular reconnaissance technique are not isolated, the broader Kuraystealer campaigns have targeted a wide range of individuals and organizations globally, resulting in significant data breaches.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEnable Sysmon process-creation logging to capture \u003ccode\u003ewmic.exe\u003c/code\u003e executions and their command-line arguments, which is essential for activating the rules below.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rules in this brief to your SIEM and tune for your environment, paying close attention to \u003ccode\u003ewmic.exe\u003c/code\u003e executions that include \u003ccode\u003ecsproduct\u003c/code\u003e in their command line.\u003c/li\u003e\n\u003cli\u003eImplement strong application whitelisting policies to prevent the execution of unauthorized infostealer payloads, which precede the use of \u003ccode\u003ewmic.exe\u003c/code\u003e for reconnaissance.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-07-03T14:47:04Z","date_published":"2026-07-03T14:47:04Z","id":"https://feed.craftedsignal.io/briefs/2026-07-hardware-model-recon-wmic/","summary":"Adversaries leverage the built-in Windows Management Instrumentation Command-line (WMIC.EXE) utility with the `csproduct` command to perform hardware model and vendor reconnaissance on target systems, a technique observed in campaigns utilizing infostealers like Kuraystealer, enabling further tailored attacks.","title":"Hardware Model Reconnaissance Via Wmic.EXE","url":"https://feed.craftedsignal.io/briefs/2026-07-hardware-model-recon-wmic/"}],"language":"en","title":"CraftedSignal Threat Feed - Kuraystealer","version":"https://jsonfeed.org/version/1.1"}
