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.
Our analysis indicates this file is a legitimate plugin for Adobe After Effects. The single detection from a low-trust engine is a common heuristic false positive triggered by the DLL's standard interaction with host processes.
The file 'xCloner.aex' is a known plugin for Adobe After Effects. While it is unsigned and triggered heuristic alerts for process injection in our sandbox, these are expected behaviors for a DLL plugin being loaded by host applications. With 16 of 17 tier-1 engines reporting it as clean and no high-trust consensus on any malicious family, the evidence points to a benign file. The single low-trust detection is consistent with heuristic flagging of legitimate software.
What We Detected
The file is a Win32 DLL identified as 'xCloner.aex', a plugin designed for Adobe After Effects. Our analysis shows that 74 of 75 engines, including all tier-1 engines, do not consider this file malicious.
Threat Behavior
The sandbox observed the DLL interacting with system processes like rundll32.exe and WerFault.exe. These actions triggered heuristic alerts for process injection (T1055) and defense impairment (T1562.001). In the context of a plugin DLL, these behaviors are standard for loading and executing functionality within the host application and do not indicate malicious intent.
What To Do Now
This file is safe to use as a plugin for Adobe After Effects. Ensure you have downloaded it from an official or trusted source to maintain the integrity of your software environment. Keep your endpoint protection enabled as a standard security practice.
Where this verdict could be wrong2 caveats
- The file is unsigned, which prevents definitive verification of its origin despite the filename matching a known commercial plugin.
- The sandbox observed process injection (T1055), which, while often benign for plugins, is a technique also used by malicious software to hide activity.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 16/17 tier-1 engines reported clean
- Filename matches known commercial plugin
- No malicious family consensus
- Unsigned executable
- Heuristic trigger for process injection (T1055)
The file is safe to use. Ensure it is obtained from a trusted source.

Consensus, attribution, signatures, code structure, prevalence, and identity.
Detection sources at a glance
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.

What to do now
This file appears low risk based on the evidence available now.
Open it only when its sender or download source is one you independently trust.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
