Is AstroLite.dll safe?
Unsigned 57 MB PE with process-injection behavior and no engine detections.
Zero of 75 engines flagged the file, yet it is unsigned and exhibits T1055 process injection in sandbox analysis. A prior imphash match was also rated suspicious. The combination of missing signature and observed injection technique places the file in mixed-signals territory.

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.
Zero of 75 engines flagged the file, yet it is unsigned and exhibits T1055 process injection in sandbox analysis. A prior imphash match was also rated suspicious. The combination of missing signature and observed injection technique places the file in mixed-signals territory.
The complete absence of detections across 75 engines, including 17 tier-1 engines, is a strong clean signal. However, the file is unsigned and the sandbox recorded T1055 process injection plus direct-IP contact, both flagged by heuristics. The single similar-hash result was also marked suspicious on the same imphash framework. Medium prevalence and no malicious children keep the risk moderate rather than high.
What We Detected
75 antivirus engines returned zero malicious detections. The PE is unsigned and 57 MB in size. Sandbox execution recorded MITRE T1055 process injection and direct-IP traffic to 162.159.36.2.
Threat Behavior
The observed T1055 technique and direct-IP contact are consistent with both legitimate and malicious software. No dropped malicious children or external-intel hits were found. Host-reputation data for the contacted IP is unavailable.
What To Do Now
Do not run the file on production systems until further verification. Keep endpoint protection enabled and consider submitting the sample to additional sandboxes for deeper behavioral review.
Where this verdict could be wrong1 caveat
- contactedHosts=null means host-reputation cross-check was not completed; cannot confirm whether the observed IP 162.159.36.2 is malicious.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections across 75 engines
- No malicious dropped children
- Medium prevalence with consistent submissions
- Unsigned executable
- Sandbox observed T1055 process injection
- Direct-IP contact without domain resolution
Treat as suspicious pending additional behavioral or code-signing evidence; maintain current security controls.

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: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
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.

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.
Evidence"C:\Users\<USER>\Desktop\program.exe"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.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
