ProcDump, a legitimate utility from Microsoft Sysinternals, is designed to monitor an application for CPU spikes and generate crash dumps. However, adversaries frequently abuse it to dump the Local Security Authority Subsystem Service (LSASS) process memory, which often contains sensitive credential material. By renaming the \u003ccode\u003eprocdump.exe\u003c/code\u003e or \u003ccode\u003eprocdump64.exe\u003c/code\u003e binary (e.g., to \u003ccode\u003edump.exe\u003c/code\u003e or \u003ccode\u003eservice.exe\u003c/code\u003e), attackers aim to bypass static detections based on file names or hash values, making their activities harder to spot for security defenders. This tactic significantly raises the risk of credential theft, enabling lateral movement and privilege escalation within compromised environments.\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: A threat actor gains initial access to a Windows system, often via phishing, exploited vulnerabilities, or RDP brute-forcing.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eTool Staging\u003c/strong\u003e: The attacker uploads a copy of ProcDump (or another legitimate tool like \u003ccode\u003ecomsvcs.dll\u003c/code\u003e for \u003ccode\u003erundll32.exe\u003c/code\u003e memory dumping) to the compromised system.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eRenaming for Evasion\u003c/strong\u003e: The ProcDump executable is renamed to a seemingly innocuous name (e.g., \u003ccode\u003edump.exe\u003c/code\u003e, \u003ccode\u003eexplorer.exe\u003c/code\u003e, \u003ccode\u003esvchost.exe\u003c/code\u003e, or other names not in the default Sysinternals installation path) to avoid detection by traditional endpoint security solutions that might whitelist or specifically monitor \u003ccode\u003eprocdump.exe\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eCredential Dumping\u003c/strong\u003e: The renamed ProcDump executable is launched via the command line to target the \u003ccode\u003elsass.exe\u003c/code\u003e process and create a memory dump. Typical command-line arguments include \u003ccode\u003e-ma\u003c/code\u003e for a full memory dump, or \u003ccode\u003e-mp\u003c/code\u003e for mini plus. The \u003ccode\u003eaccepteula\u003c/code\u003e flag is often used to suppress the license agreement prompt.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eExfiltration\u003c/strong\u003e: The generated LSASS memory dump file, which may contain NTLM hashes, Kerberos tickets, or clear-text passwords, is compressed or encrypted and exfiltrated from the network to attacker-controlled infrastructure.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eLateral Movement/Privilege Escalation\u003c/strong\u003e: The stolen credentials are used for lateral movement to other systems, accessing sensitive resources, or escalating privileges within the compromised environment.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this technique can lead to severe organizational impact, including widespread credential theft and unauthorized access across the enterprise network. Compromised credentials allow threat actors to escalate privileges, move laterally to critical systems, bypass multi-factor authentication (if not properly configured), and gain persistence. This often precedes data exfiltration, deployment of ransomware, or other destructive activities, resulting in significant financial losses, operational disruption, and reputational damage. The pervasive nature of credential abuse makes it a high-priority threat for detection engineers.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDeploy the provided Sigma rule \u0026quot;Detecting Renamed ProcDump Execution\u0026quot; to your SIEM to identify suspicious ProcDump activity.\u003c/li\u003e\n\u003cli\u003eEnsure Sysmon process-creation logging is enabled to provide the necessary \u003ccode\u003eOriginalFileName\u003c/code\u003e, \u003ccode\u003eImage\u003c/code\u003e, and \u003ccode\u003eCommandLine\u003c/code\u003e fields for the detection rule.\u003c/li\u003e\n\u003cli\u003eInvestigate any alerts generated by the rule, especially those involving \u003ccode\u003eOriginalFileName: 'procdump'\u003c/code\u003e where \u003ccode\u003eImage\u003c/code\u003e does not end in \u003ccode\u003e\\procdump.exe\u003c/code\u003e, \u003ccode\u003e\\procdump64.exe\u003c/code\u003e, or \u003ccode\u003e\\procdump64a.exe\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eImplement strong access controls and principle of least privilege to limit the ability of non-administrative accounts to execute or rename tools in sensitive directories.\u003c/li\u003e\n\u003cli\u003eRegularly review and harden endpoint security configurations to block or alert on the execution of non-standard binaries in unexpected locations.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-07-03T14:23:37Z","date_published":"2026-07-03T14:23:37Z","id":"https://feed.craftedsignal.io/briefs/2026-07-renamed-procdump-execution/","summary":"This brief focuses on the detection of renamed Sysinternals ProcDump executables, a technique often employed by threat actors to evade security controls and perform credential dumping from LSASS memory on Windows systems, leading to potential lateral movement and privilege escalation.","title":"Detecting Renamed ProcDump Execution for Evasion","url":"https://feed.craftedsignal.io/briefs/2026-07-renamed-procdump-execution/"}],"language":"en","title":"CraftedSignal Threat Feed - Windows Sysinternals ProcDump","version":"https://jsonfeed.org/version/1.1"}
