Is trayicon.exe safe?
Twelve of 74 engines flagged this new unsigned executable, while sandbox evidence mapped possible process injection, token manipulation, and defense impairment.
The file has a concerning combination of 12 antivirus detections and four offensive runtime techniques, including process injection and defense impairment. However, only one tier-1 engine detected it, no family consensus formed, and the sandbox issued no explicit malware finding, so the evidence remains mixed.

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.
The file has a concerning combination of 12 antivirus detections and four offensive runtime techniques, including process injection and defense impairment. However, only one tier-1 engine detected it, no family consensus formed, and the sandbox issued no explicit malware finding, so the evidence remains mixed.
Twelve of 74 engines detected the executable, with Microsoft identifying a generic Wacatac trojan pattern. The completed sandbox mapped activity to T1055, T1134, T1134.001, and T1562.001, which are materially concerning techniques rather than ordinary installer activity. The file is unsigned, newly observed, and represented by only one source, leaving no established publisher or prevalence history to offset those signals. Conversely, 16 of 17 tier-1 engines did not flag it, no engine family consensus exists, and the sandbox did not issue an explicit malware finding. No complete contacted-host reputation result is available, although the saved run itself contains no network contacts.
What We Detected
12 of 74 antivirus engines flagged trayicon.exe. Microsoft reported Trojan:Win32/Wacatac.B!ml, while the remaining detections were largely generic or behavior-based and did not converge on one family. The executable is unsigned and was first observed today, with four submissions from one source.
Threat Behavior
One completed sandbox run mapped activity to T1055 (Process Injection), T1134 and T1134.001 (access-token manipulation), and T1562.001 (impair defenses). These techniques raise meaningful concern, but the sandbox did not issue an explicit malware finding, record persistence, write files, or identify dropped payloads. The run recorded no network contacts; a separate host-reputation cross-check was not completed or saved.
What To Do Now
Do not run the file on a production or personal system unless its source and expected purpose can be independently verified. Keep endpoint protection enabled, quarantine the executable, and obtain a fresh copy from the software publisher's official release channel if it was expected.
Where this verdict could be wrong4 caveats
- Only 1 of 17 tier-1 engines flagged the sample, while Avast, BitDefender, ESET-NOD32, Fortinet, and other tier-1 engines did not detect it.
- behaviour.hasMaliciousSandboxVerdict=false, and the saved run recorded no contacted domains, IPs, URLs, persistence indicators, or written files.
- externalIntel.malwareBazaar.hit=false and externalIntel.circl.hit=false, although absence from those collections does not establish benignity.
- peAnalysis.likelyPacked=false and peAnalysis.highEntropyCode=false, providing no static packing indicator.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 16 of 17 tier-1 engines did not detect the file
- No strong tier-1 family consensus
- No explicit malicious sandbox verdict
- No recorded dropped files or persistence indicators
- No packing or high-entropy code indication
- 12/74 antivirus detections
- Microsoft detection: Trojan:Win32/Wacatac.B!ml
- Runtime mapping to T1055 process injection
- Runtime mapping to T1562.001 defense impairment
- Unsigned Win32 executable
- First observed today with one contributing source
Quarantine the file and verify its origin before execution; use an official publisher download if available. Keep antivirus and endpoint protection enabled.

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: Used an input-capture technique that can record credentials or keystrokes.
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.
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.

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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. 12 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.
