Chapter 02
Why we think so
4 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The archive drew 31 detections among 75 engines, including six major detections and 24 independent engine votes. Execution launched an injector, loaded a native DLL through rundll32, and mapped T1055, T1543.002, and T1562.001, strongly supporting the trojan detections despite one clean sandbox verdict.
Detection is broad: 31 of the 60 antivirus engines that checked it flagged the archive, with six major detections and 24 independent votes. BitDefender identified Yogi, while ESET-NOD32 and Fortinet reported Kryptik-family trojan variants; the exact family naming is not unanimous. The completed runtime run launched Vape421Injector.exe, loaded Vape421Native.dll through rundll32.exe, and mapped process injection, service execution, and defense impairment. The sandbox's clean verdict is meaningful dissent, but it conflicts with both its own recorded activity and the strong antivirus evidence. No complete contacted-host reputation result is available, and the ten dropped files remain unclassified rather than cleared.
What We Detected
Thirty-one of the 60 antivirus engines that checked it flagged the ZIP archive. Six major antivirus engines detected it, and the detections represent 24 independent engine votes after related products were consolidated. BitDefender and several related labels identify Yogi variants, while ESET-NOD32 and Fortinet identify GenKryptik or Kryptik trojans; this supports a trojan assessment even though the family labels are not fully consistent.
Threat Behavior
The completed sandbox run extracted multiple executables, a DLL, a batch file, and a Java service into a temporary directory. It then launched Vape421Injector.exe and used rundll32.exe to load Vape421Native.dll. No target process was identified for the injection mapping, so the precise injection method remains unproven.
The sandbox itself returned a clean verdict, and no malware-specific external research rule corroborated the sample. However, these counter-signals do not outweigh the breadth and quality of detections plus the injector-related activity in the test run. The dropped files have no saved verdicts, and no complete host-reputation cross-check is available.
What To Do Now
Do not extract or execute this archive. Quarantine or delete it while keeping security software enabled. If it was already run, disconnect the affected system from sensitive networks, perform a full security scan, and review services, temporary files, and account activity for unauthorized changes.
Where this verdict could be wrong3 caveats
- The completed sandbox run returned a clean verdict, although it still recorded several offensive-technique mappings and injector-related execution.
- No malware-specific YARAify rule or MalwareBazaar record corroborated the detections.
- None of the ten dropped files has a saved malicious verdict, but all ten remain unclassified rather than cleared.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- The completed sandbox run returned a clean verdict.
- No malware-specific external research rules or sample-feed record corroborated the file.
- No persistence indicators or sample-attributed network contacts were recorded in the completed run.
- Thirty-one of the 60 antivirus engines that checked it flagged the archive, including six major antivirus engines.
- The detections represent 24 independent engine votes rather than only related vendor products.
- Behaviour in the test run launched an injector and loaded a native DLL through rundll32.
- The archive extracted multiple executable components into a temporary directory.

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Checked whether it was running on a test computer.
Moderate concern: Hid files or windows on the test computer.
Note: Listed the programs running on the test computer.
Note: Read basic details of the test computer, such as its Windows version.
Note: Loaded extra code modules while running.
Note: Checked which security software was installed on the test computer.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as downloading a file, but no download was recorded.
Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.
Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
Threat context
How trojans work
A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
