Is Wave.zip safe?
ZIP archive containing PE that triggered seven tier-1 engines and executed process-injection plus data-destruction techniques.
Seven tier-1 engines flagged the sample as Win64:MalwareX-gen / TR/W64.Agent. Sandbox observed T1055 process injection, T1485 data destruction, and direct-IP traffic to two external hosts. No malicious dropped children or known-bad hosts were found, but the tier-1 consensus and offensive MITRE techniques outweigh those gaps.

Before opening or extracting
Do not open or extract it. Delete this archive from the device, then empty the Recycle Bin or Trash.
If you already opened or extracted it
Close it. If it opened links, requested credentials, or triggered unexpected behavior, disconnect from the internet and run a full device scan.

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.
Seven tier-1 engines flagged the sample as Win64:MalwareX-gen / TR/W64.Agent. Sandbox observed T1055 process injection, T1485 data destruction, and direct-IP traffic to two external hosts. No malicious dropped children or known-bad hosts were found, but the tier-1 consensus and offensive MITRE techniques outweigh those gaps.
The file is a 28 MB ZIP that expands to a PE exhibiting three offensive MITRE techniques. Seven independent tier-1 engines converged on malicious verdicts, including Avast, AVG, Avira, F-Secure, Fortinet, GData and Sophos. Runtime evidence shows rundll32 loading suspicious DLLs and direct-IP connections without domain names. Although no secondary malicious children or cached malicious hosts were detected, the combination of tier-1 consensus and offensive behaviour is decisive.
What We Detected
24 of 75 engines flagged the archive malicious; 7 of those are tier-1. The dominant family label is MalwareX / Agent. Sandbox execution recorded T1055 (process injection), T1485 (data destruction) and T1562.001 (impair defences) plus direct-IP traffic to 172.67.175.40 and 162.159.36.2.
Threat Behavior
The extracted PE writes multiple WebView2 cache files and loads two DLLs via rundll32. No persistence registry keys were observed, but the process-injection and defence-impairment techniques indicate capability to evade detection and potentially destroy data.
What To Do Now
Do not execute the archive. Delete the file and any extracted contents. Keep endpoint protection enabled and scan the system with a second opinion engine if the archive was opened.
Where this verdict could be wrong1 caveat
- droppedChildren.hasMaliciousChild=false and contactedHosts.maliciousHosts.length=0 — no secondary malicious artifacts observed.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No malicious dropped children
- no complete contacted-host reputation result was available
- Medium prevalence across 1818 submitters
- 7 tier-1 malicious detections
- T1055 process injection observed
- T1485 data destruction capability
- Direct-IP C2 traffic recorded
Quarantine and delete the archive; do not run any extracted executables. Maintain current antivirus definitions and avoid opening similar unsolicited archives.

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: Changed an auto-start location that can make code run after sign-in or restart.
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: 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.
Threat context
How trojans work
A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything 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
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:\Windows\system32\rundll32.exe" "C:\Users\<USER>\AppData\Local\Temp\WaveUIAuth.dll",#1The 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.
