Is Updater.exe safe?
Strong tier-1 consensus on MalwareX family plus runtime process-injection evidence.
23 of 75 engines flag the file, including 7 tier-1 engines that converge on the MalwareX family. Runtime behaviour shows process injection (T1055) and privilege escalation (T1548). The executable is signed by an unknown signer with no prior history.

Before running
Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash.
If you already ran it
Disconnect from the internet, start a full or offline antivirus scan, then secure important accounts from a clean device.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
23 of 75 engines flag the file, including 7 tier-1 engines that converge on the MalwareX family. Runtime behaviour shows process injection (T1055) and privilege escalation (T1548). The executable is signed by an unknown signer with no prior history.
The tier-1 consensus on MalwareX is decisive: Avast, AVG, Avira, ESET-NOD32, F-Secure, GData, Microsoft, Sophos and Symantec all return matching malicious labels. Behaviour logs confirm offensive MITRE techniques T1055, T1548 and T1562.001, corroborated by the triggered heuristic for process injection. The certificate is present but the signer "Updater" has zero historical samples, eliminating any benign-signed-installer defence. No clean RAG matches or external-intel hits exist to offset the detections.
What We Detected
23 of 75 engines report malicious, 7 of them tier-1, converging on the MalwareX family. The file carries a code signature from an unknown publisher "Updater" with no prior reputation. Sandbox execution recorded MITRE techniques T1055 (process injection), T1548 (privilege escalation) and T1562.001 (impair defences).
Threat Behavior
The sample writes temporary .mp4 files and spawns processes from the user Desktop, consistent with dropper or loader activity. No external domains were contacted during the observed run, but the incomplete no complete contacted-host reputation result was available network behaviour.
What To Do Now
Do not execute the file. Keep endpoint protection enabled and submit the sample to your security vendor for deeper analysis if additional context is required.
- Strong tier-1 family consensus on MalwareX
- Runtime evidence of process injection and privilege escalation
- Unknown signer with no historical samples
- Recently observed (1 day) with negative reputation
Block the file and investigate any systems where it has already run; retain endpoint protection.

Complete means the check returned a usable result. It does not mean the file is safe.

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: Attempted to impair or bypass security controls.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Note: Reads your Windows user-account details.
Note: Listed running processes; both legitimate software and malware may do this.
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.
