Is ZombieBuddyInstaller_v4.1.exe safe?
Only low-trust MaxSecure detected this installer, but numerous community YARA matches and a T1055 runtime mapping warrant caution pending publisher verification.
MaxSecure alone flagged the file among 75 engines, while every reporting tier-1 engine found no issue. However, the unsigned executable matched 27 community YARA rules and its sandbox record mapped activity to T1055, so the evidence is too mixed to dismiss without verification.

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.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
MaxSecure alone flagged the file among 75 engines, while every reporting tier-1 engine found no issue. However, the unsigned executable matched 27 community YARA rules and its sandbox record mapped activity to T1055, so the evidence is too mixed to dismiss without verification.
The antivirus result strongly resembles a false positive because only MaxSecure flagged the sample and all 17 reporting tier-1 engines were silent. Its moderate prevalence, lack of packing indicators, and non-malicious sandbox conclusion provide additional reassurance. Against that, the executable is unsigned, 27 community YARA rules matched it, and runtime evidence mapped possible process injection to T1055. The YARA matches include broad rules and therefore do not establish a specific malware family, but their number makes them material. Host checks found no listed threats for the three inspected domains, although the separately observed IP lacks documented coverage. Overall, independent warning signs justify isolation and source verification rather than immediate execution.
What We Detected
Only 1 of 75 antivirus engines flagged the executable. That detection came from low-trust MaxSecure under the generic label Trojan.Malware.300983.susgen; all 17 reporting tier-1 engines found no issue. The file is unsigned, so there is no verified publisher identity to support the installer claim.
Threat Behavior
One completed sandbox run did not issue a malicious conclusion, but its saved activity mapped possible process injection to MITRE T1055. Community scanning also produced 27 YARA matches, including command_and_control and CP_Script_Inject_Detector. These rules may be broad or overlap, and they do not identify a reliable family, but they are significant counter-signals. Three contacted domains were inspected without reputation hits; the separately observed IP was not documented as inspected, so host-reputation coverage was incomplete.
What To Do Now
Do not run the installer until its download source and expected checksum are verified through the software publisher's official channel. Keep endpoint protection enabled, and test only in an isolated environment if verification is unavailable.
Where this verdict could be wrong4 caveats
- All 17 reporting tier-1 engines were clean, and the only detection came from low-trust MaxSecure.
- The completed sandbox did not issue a malicious verdict, and droppedFileHashes is empty.
- contactedHosts found no malicious or suspicious entries among three inspected domains, although the observed IP was not shown as inspected.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false provide no static indication of packed executable code.
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 detected the file, and that detector was low-trust MaxSecure
- All 17 reporting tier-1 engines found no issue
- The completed sandbox issued no malicious conclusion
- No dropped file hashes or persistence indicators were recorded
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false
- Unsigned Win32 executable with no verified publisher identity
- 27 community YARA rules matched the sample
- Runtime evidence mapped possible process injection to T1055
- Observed IP address lacks documented host-reputation coverage
- No trusted signer history is available
Quarantine the file while confirming its source and SHA-256 with the publisher's official release channel. Keep endpoint protection enabled and avoid normal-system execution unless the file can be independently authenticated.

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: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Note: Loads extra code modules while running.
Note: Connected to 4 servers during sandbox analysis.
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 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.
