Is Core-Temp-setup-v1.20.1.150.exe safe?
Legitimate Core Temp installer signed by ALCPU with only a single low-trust grayware flag and clean sandbox behaviour.
The file is a common signed installer for Core Temp CPU monitoring software. Only one low-trust engine flagged it as grayware; all tier-1 engines and sandbox analysis are clean. High submission volume and installer-typical behaviour confirm it is safe.

Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The file is a common signed installer for Core Temp CPU monitoring software. Only one low-trust engine flagged it as grayware; all tier-1 engines and sandbox analysis are clean. High submission volume and installer-typical behaviour confirm it is safe.
The single malicious detection comes from a low-trust engine with a generic grayware label and no tier-1 support. The file is properly signed by ALCPU, shows typical Inno-Setup installer behaviour (process injection, persistence, direct-IP contact during install), and has no malicious dropped children or sandbox verdicts. Prevalence is high (common_new) with explicit researcher confirmation of no threat. These factors outweigh the heuristic triggers.
What We Detected
Single low-trust detection (CrowdStrike grayware). Verified signature by ALCPU. Installer behaviour with MITRE T1055/T1548 etc. No malicious children or hosts.
Threat Behavior
None. Observed techniques are standard for legitimate installers; no C2, no data exfiltration, no persistence beyond install.
What To Do Now
Safe to install from official source. No action required.
Where this verdict could be wrong1 caveat
- If the ALCPU certificate were compromised the signing would be misleading, but prevalence=common_new across 1701 submissions and zero tier-1 detections make stolen-cert scenario unlikely.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Verified signature by ALCPU
- High prevalence common_new
- Zero tier-1 malicious detections
- Clean sandbox and dropped children
Treat as safe; install only from the official ALCPU/Core Temp website.

Detection sources at a glance
The available sources did not agree on a named threat category.
This legacy report does not record whether the independent reference checks completed.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
Sandbox flagged persistence indicators (registry Run keys / services / scheduled tasks).
EvidenceALSysIOMITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
EvidenceC:\Windows\Explorer.EXESandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
