Is detection.exe safe?
Only Gridinsoft raised a PUP detection, but observed process-injection and LSASS-related indicators warrant caution despite broad tier-1 silence and a verified signature.
Gridinsoft alone flagged the executable as Caypnamer PUP, while all 17 tier-1 engines reported no detection. However, one sandbox run mapped activity to process injection and service creation, with an additional LSASS-related warning, so the file should not be trusted solely on the low detection count.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
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.
Gridinsoft alone flagged the executable as Caypnamer PUP, while all 17 tier-1 engines reported no detection. However, one sandbox run mapped activity to process injection and service creation, with an additional LSASS-related warning, so the file should not be trusted solely on the low detection count.
The antivirus result is weak in isolation: only 1 of 75 engines flagged the sample, and none of the 17 tier-1 engines did. The file carries a valid Husdawg signature, but the signer is neither on the trusted-publisher list nor backed by historical sample statistics. Runtime evidence mapped activity to T1055 and T1543.003, and a heuristic associated observed LSASS-related process activity with credential-dumping behavior. No sandbox supplied a malicious verdict, no inspected child was identified as malicious, and external intelligence produced no corroborating hit. Host-reputation coverage was incomplete because only one host was inspected despite several distinct observed contacts, leaving the network evidence inconclusive.
What We Detected
Gridinsoft was the only engine among 75 to flag the executable, labeling it PUP.Win64.Caypnamer.dd!c. All 17 tier-1 engines reported no detection, and there was no family consensus. The file is validly signed by Husdawg, but that publisher has no established history in the available signer records and is not on the curated trusted-publisher list.
Threat Behavior
One completed sandbox run mapped activity to process injection (T1055) and Windows service creation or modification (T1543.003). A separate heuristic associated LSASS-related process activity with credential-dumping behavior, although the available process evidence does not by itself prove memory access or credential theft. The sandbox did not issue a malicious verdict, and the inspected child was not identified as malicious. Only one contacted host received a reputation cross-check despite several distinct domain, IP, and URL contacts, so a complete host-reputation result is unavailable.
What To Do Now
Do not run the executable on a production or personal system until its origin and publisher can be independently verified. Keep endpoint protection enabled, obtain a fresh copy from the official source, and use an isolated test environment if further validation is necessary.
Where this verdict could be wrong4 caveats
- All 17 tier-1 engines reported no detection, substantially weakening Gridinsoft's lone PUP label.
- The completed sandbox produced no malicious sandbox verdict, and no inspected child was identified as malicious.
- The file has medium prevalence with 2,731 submitters and 3,235 submissions, which is less consistent with a narrowly distributed new threat.
- The executable is verified-signed and peAnalysis.likelyPacked=false, though the publisher has no recorded history.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1/75 engines reported a detection.
- engines.tier1Malicious=0, with all 17 tier-1 engines reporting no detection.
- signing.verified=true for 'Husdawg'.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false and externalIntel.yaraify.ruleCount=0.
- Runtime mapping includes process injection technique T1055.
- Runtime mapping includes service creation or modification technique T1543.003.
- MalwareTips.Synth.CredentialDumper associated observed LSASS-related activity with credential-access risk.
- Gridinsoft reported PUP.Win64.Caypnamer.dd!c.
- The verified signer 'Husdawg' has no available historical reputation.
- Contacted-host reputation coverage was incomplete.
Quarantine the file pending source and publisher verification, and keep endpoint protection enabled. If it must be evaluated, use an isolated environment rather than a production machine.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Created or modified a system service, which can keep code running.
High concern: Attempted to impair or bypass security controls.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Communicates over the network in a non-standard way.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
EvidenceC:\Windows\System32\svchost.exe -k NetworkService -pSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
