Safe
Legitimate Core Temp installer signed by ALCPU with only a single low-trust grayware flag and clean sandbox behaviour.
26e9a2b20608f00f43…078d9b5606The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
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.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
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.exeSample contacted 2 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

Section entropy & packers
Section-level entropy and packer detection from the PE header. Nothing suspicious here — entropy is within the normal range for unpacked code.
How widely this file has been seen
Lots of people are uploading this but it's recent — typical of newly-released legitimate software. Low prior for malware.

Safety FAQ
Common questions about Core-Temp-setup-v1.20.1.150.exe, answered from the scan data above.
- Core-Temp-setup-v1.20.1.150.exe appears safe. 74 of 75 antivirus engines report it clean, with only 1 low-confidence detection that read as false positives. It carries a verified digital signature from ALCPU. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- Core-Temp-setup-v1.20.1.150.exe is a Windows executable program, about 1.6 MB. Our analysis found no threat indicators for it. It carries a verified digital signature from ALCPU. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- 1 of 75 antivirus engines flagged Core-Temp-setup-v1.20.1.150.exe, 1 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- Yes — Core-Temp-setup-v1.20.1.150.exe carries a valid digital signature from ALCPU, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
- The SHA-256 hash of Core-Temp-setup-v1.20.1.150.exe is 26e9a2b20608f00f43a44d0f7fa57e70a832087c3d4a9aa1d8dc73078d9b5606, and its MD5 is 7edd792d56093efe9b7ad08fe3dcaf13. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- Based on this scan, yes — Core-Temp-setup-v1.20.1.150.exe shows no threat indicators and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on May 26, 2026. Because a file's hash never changes, the identity of Core-Temp-setup-v1.20.1.150.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
