Is setup.exe safe?
Installer signed by unknown publisher with imphash matches to OfferCore PUA and observed process-injection techniques.
Zero engines flagged the file, yet the imphash matches four prior OfferCore samples and the runtime shows process-injection and privilege-escalation techniques. The signer has no history and the file drops multiple children while contacting direct IPs.
b98e867528875161cb…add032f82e1077Recommended next actions
Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer 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.
Zero engines flagged the file, yet the imphash matches four prior OfferCore samples and the runtime shows process-injection and privilege-escalation techniques. The signer has no history and the file drops multiple children while contacting direct IPs.
The complete absence of detections across 75 engines is a strong clean signal, but the imphash similarity to known OfferCore samples and the presence of four offensive MITRE techniques outweigh that signal. The signer lacks any prior reputation, and the installer writes multiple dropped children while contacting direct IPs. These mixed indicators place the file in the suspicious band rather than safe or malicious.
What We Detected
75 engines reported the file clean. The binary is signed by 'IZHAN INC' with no prior samples from that signer. Runtime evidence shows process injection (T1055), data destruction (T1485), and privilege escalation (T1548) techniques.
Threat Behavior
The installer drops ten child files, contacts seven direct IP addresses, and writes to protected directories. Four of five similar imphash samples were previously classified as OfferCore PUA or downloader.
What To Do Now
Do not run the installer. Keep endpoint protection enabled. If the file is required, execute it only in an isolated virtual machine and monitor for unexpected network or process activity.
Where this verdict could be wrong1 caveat
- Zero engine detections and medium prevalence argue against malicious classification despite imphash matches.
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
- Medium prevalence with 275 submitters
- No malicious child files or sandbox verdicts
- Imphash matches known OfferCore samples
- Four offensive MITRE techniques observed
- Signer has no established history
- Direct-IP network contacts without domain names
Treat as suspicious; avoid execution on production systems until further reputation data or a trusted publisher version is available.

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.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
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.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Reads your Windows user-account details.
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.

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\Explorer.EXEThe 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 install 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
If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Download a fresh installer from the developer's official site or an official app store.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
