Is CMT_Bitcrusher_2.dll safe?
Unsigned, packed DLL with one low-trust detection and process-injection indicators but no tier-1 consensus.
One low-trust engine flagged the file; 74 others did not. The DLL is unsigned, UPX-packed, and exhibits T1055 process-injection behaviour plus direct-IP network activity, yet no tier-1 engine or external-intel source corroborates malice.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
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.
One low-trust engine flagged the file; 74 others did not. The DLL is unsigned, UPX-packed, and exhibits T1055 process-injection behaviour plus direct-IP network activity, yet no tier-1 engine or external-intel source corroborates malice.
The single malicious detection originates from a low-trust engine, leaving tier1Malicious at zero and onlyLowTrustFlagging true. The file is unsigned and packed, and sandbox evidence shows T1055 plus direct-IP contacts, but the absence of tier-1 consensus and the decade-long prevalence without escalation keep the risk moderate. Contacted-host reputation data is unavailable, so network activity cannot be fully assessed. Overall the evidence is mixed rather than decisive.
What We Detected
75 engines scanned the sample; only Cynet (low_trust) returned a malicious result. The DLL is unsigned, contains UPX-packed sections, and triggered high-severity heuristics for process injection (T1055) and dropper/stager network behaviour.
Threat Behavior
Runtime artefacts include direct-IP connections to 13.64.90.137 and 13.88.21.125, creation of WER crash-report files, and several mutexes. No dropped child files were flagged malicious and no tier-3 engine or external-intel source (CIRCL, MalwareBazaar, YARAify) corroborates a known family.
What To Do Now
Keep endpoint protection enabled. If the DLL is required, run it only in an isolated environment and monitor for unexpected outbound traffic or process injection attempts. Consider obtaining a signed, vendor-distributed replacement if this component is part of legitimate software.
Where this verdict could be wrong1 caveat
- prevalence.classification=common_old with 117 unique sources over 4549 days suggests the file has been widely distributed for a decade without tier-1 consensus
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 flagged the file
- No tier-1 malicious detections
- Widely submitted since 2014 without escalation
- Unsigned PE
- UPX packing with high-entropy code section
- T1055 process-injection technique observed
- Direct-IP network activity without domain resolution
Treat the file as suspicious; do not execute it on production systems until additional signed or vendor-verified copies can be obtained.

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.
EvidenceT1055 (MITRE)The 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.
Evidence13.64.90.137 · 13.88.21.125Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.

Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
