stanarcservice.com: a Windows ClickFix malware site (s.ps1) and what to do if you pasted its command

What stanarcservice.com is, and what we know about it

stanarcservice.com is a web address, not a program on your PC. It is a domain that the abuse.ch project URLhaus lists as a place where malware was served, and one of its three entries carries the tag ClickFix. No public write-up of this one domain exists that we could find, so this page rests on what URLhaus shows, what we saw ourselves and what Microsoft and others have published about the trick.

1. 1

   What URLhaus lists

   Three file addresses on stanarcservice.com. On 8 October 2026 a reporter using the name 0xJustme added http://stanarcservice[.]com/s.ps1 with the tags ClickFix and ps1. On 9 October 2026 at 06:10 UTC abuse.ch itself added a file under /asset/update.dat and a file under /payload/ on port 8443 with a .bin ending. All three are listed with the threat type malware_download.

2. 2

   What the tags mean

   ps1 is the ending of a PowerShell script. ClickFix is a trick in which a fake verification or fix page makes you copy a command and run it yourself. Together they say that the script was meant to be started by a command a visitor pasted. The other two entries have no tags, so we do not know what they are.

3. 3

   What we could not confirm

   We did not download any of the files and we never saw the page that tells visitors what to paste. So we do not know the lure, what the script does, which malware family it installs or whether the three files belong to one chain. The ClickFix tag is the reporter's label, not our finding.

4. 4

   What this means for you

   If you only saw the name in a log, a link or a warning, you are not infected by that alone. The risk is for people who pasted a command from the site into the Run box, Windows Terminal or PowerShell, or who opened a file from it.

Kind of threat

A malware download address; one entry is a PowerShell script tagged ClickFix

Delivery trick

ClickFix: a fake page asks you to copy a command and paste it into Run, Terminal or PowerShell

Domain registered

25 June 2026, expires 25 June 2027, registrar HOSTINGER operations, UAB (RDAP, read 9 October 2026)

URLhaus entries

3 file addresses, added 8 and 9 October 2026; 2 online and 1 offline when we read them

Platform

Windows, by the ps1 tag. No source says which other systems are hit

What we checked on 9 October 2026, and what we could not

We opened https://stanarcservice.com/ once, from Lithuania, in an automated Chromium browser set to English. The connection was refused and no page loaded. That tells you nothing good about the site, and it clears nothing.

What happened to stanarcservice.com, from registration to our test

The history is short: the domain is under four months old and was first reported two days before our test. The dates come from RDAP and from the URLhaus database.

1. 25 June 2026

   The domain is registered

   RDAP shows stanarcservice.com registered on 25 June 2026 through the registrar HOSTINGER operations, UAB, valid until 25 June 2027. The name sounds like a service company; nothing we found shows a real business behind it.

2. 8 October 2026

   A ClickFix PowerShell script is reported

   At about 05:52 UTC the reporter 0xJustme adds http://stanarcservice[.]com/s.ps1 to URLhaus with the tags ClickFix and ps1. This is the first time URLhaus sees the host.

3. 9 October 2026

   Two more files are added

   At 06:10 UTC abuse.ch adds a file under /asset/update.dat and a file under /payload/ on port 8443, with a .bin ending. Both have no tags. The first is online and the second offline when we read them.

   

4. 9 October 2026

   Our test is refused

   Our browser visit to https://stanarcservice.com/ ends in ERR_CONNECTION_REFUSED. We do not know what a visitor who arrives from the lure page would see.

We could not read the URLhaus pages themselves, because they ask for a browser check. The entries above come from the same data in our own database, which holds the URLhaus feed.

How the ClickFix trick works on Windows

ClickFix does not use a security hole. It makes you do the infecting yourself, so the warnings of your browser and your antivirus often never get a say. We did not see stanarcservice.com's page; this is how Microsoft describes the trick.

1. 1

   You land on a page with a check

   Microsoft says the lures arrive through phishing email, malicious ads or compromised sites, often as a fake CAPTCHA or verification prompt. The page looks like a human check, a browser fix or a Windows problem.

2. 2

   The page copies a command for you

   A button such as Verify puts a command on your clipboard without showing it. The page then tells you to paste it into the Run dialog, Windows Terminal or PowerShell.

3. 3

   You open Run and paste

   The steps ask you to press the Windows key + R, press Ctrl + V and press Enter. Microsoft notes that the Run dialog is a trusted input that starts the command through the system itself, and that most of these attacks end in PowerShell or HTA script execution.

4. 4

   The command fetches the real malware

   What you paste is usually one short line that downloads a script from the attackers' server and runs it. A file named s.ps1 on a server is the kind of file such a line fetches. We do not know that this is what happened here.

5. 5

   Nothing seems to happen

   A window that flashes and closes, or a CAPTCHA that never finishes, is the whole experience for many victims. Microsoft says payloads are often fileless and loaded into memory through built-in tools such as powershell.exe, msbuild.exe and regasm.exe.

Because a person starts the command, many automated defences treat it as normal. This is why the Run box history matters later: Windows records what was typed there.

The three files: what each name suggests, and what we do not know

File names are weak evidence. We list what each one could be and mark which statements are only a reading of the name.

The path /payload/ and the port 8443 show that someone organised the server for more than one file. That is as much as the names allow. We did not fetch the files, so we give no malware family name.

What a ClickFix payload on Windows can take

We do not know what stanarcservice.com's script installs. Microsoft names the payloads it has seen at the end of ClickFix chains, and the list below is those, not a claim about this site.

What this can cost you

Reading the site name or seeing a warning costs nothing. The risks below apply to a PC where the command was pasted and run, or a file from the site was opened.

• High

  Account takeover

  A stealer takes cookies and session tokens, which let someone use your email, social and work accounts without your password. Changing the password alone may not end a stolen session.

• High

  Crypto theft

  Wallet files and extensions are a main target for stealers. Stolen crypto cannot be reversed, so move funds before you do anything else on the PC.

• High

  Someone else controlling the PC

  If the payload is a remote access tool, a person can watch the screen, type and install more tools. Disconnect the PC first.

• Medium

  A hidden program that starts again

  Microsoft describes scheduled tasks and Startup folder files used to survive a restart. Until they are gone, the PC keeps contacting the attackers.

• Medium

  Work accounts and company data

  On a work PC the passwords and tokens in the browser reach company systems. Tell your IT or security team at once; they can block the accounts.

• Low

  Nothing, if you only saw the name

  A name in a warning, a firewall log or a blocked link is not an infection.

What you may notice, and what you may not

Most victims notice nothing. The signs below follow from how ClickFix chains work; the first two are the best evidence you have.

How people end up on a page like this

We do not know how visitors reach stanarcservice.com, and no source says. The routes below are the ones Microsoft names for ClickFix in general.

1. 1

   A phishing email with a link

   The email says an invoice, a document or a delivery needs a check. The link opens a fake verification page.

2. 2

   A malicious ad

   Ads on search results or free-download sites send you to the check page. Microsoft lists malvertising as a route.

3. 3

   A hacked website

   A normal site that was broken into shows the fake check on top of its own page. Microsoft lists compromised sites too.

4. 4

   A fake Windows or browser fix

   Pages that claim your browser or Windows needs an update, or that a document cannot be shown until you fix it, end in the same paste step.

Check your Windows PC before you delete anything

Start with the question that matters: did you paste a command from a website into Run, Windows Terminal or PowerShell, or open a file from stanarcservice.com? If yes, follow the numbered plan on this page, because a clean-looking check does not clear a PC. If you are not sure, do these checks first. None of them deletes anything.

While you check, stop using the PC for banking, email, work or crypto, and disconnect it from Wi-Fi and network cables if you can. Elastic's guidance for this kind of command is to isolate the host if a second stage may have run.

1. 1

   Read the Run box history

   Open Registry Editor (press the Windows key, type regedit, press Enter) and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU. Each value is a line typed into Run. Look at it, do not run it, and do not delete it yet. Write down or photograph any line that names stanarcservice.com or contains powershell, iex or a web address.

2. 2

   Look for a scheduled task you did not make

   Press the Windows key, type Task Scheduler and open it. Select Task Scheduler Library and read the names and the Actions tab of any task that is new or has a random name. Do not delete anything yet; note the name.

3. 3

   Look in the Startup folder

   Press Windows key + R, type shell:startup and press Enter. A file you did not put there, such as a .cmd file named after your PC, is what Microsoft describes for Lampion. Note it.

4. 4

   Check Windows Security

   Open Windows Security > Virus & threat protection > Protection history. On Windows 10 the same page is under Settings > Update & Security > Windows Security. Look for detections dated around the time you pasted the command.

5. 5

   Remember what a clean check means

   Clearing RunMRU removes evidence of the command, not the malware. Fileless payloads may leave nothing in these places. A clean check lowers the doubt; it does not remove it.

Scan from outside Windows: Microsoft Defender Offline

An offline scan runs before the normal Windows starts, so a hidden program cannot hide from it as easily. Microsoft's page says it targets malware that tries to bypass the Windows shell, such as rootkits.

1. 1

   Prepare

   Save your work and close programs. Microsoft says the scan takes about 15 minutes and restarts the PC. It needs a PC with an administrator account and Windows Recovery Environment turned on. To check, open a Command Prompt as administrator and run reagentc /info; if it says Disabled, run reagentc /enable.

2. 2

   Suspend BitLocker if it is on

   If BitLocker protects the system drive, suspend it first. Otherwise the PC may ask for your recovery key when it restarts into the offline scan.

3. 3

   Start the scan

   Open Windows Security > Virus & threat protection > Scan options. Choose Microsoft Defender Offline scan and select Scan now. Agree to the prompts. The PC signs you out, restarts into the scan and starts Windows again when it ends.

4. 4

   Read the result

   Open Windows Security > Virus & threat protection > Protection history. Microsoft says the scan only works on x64 Windows 10 and 11, not on ARM, and that it needs Microsoft Defender Antivirus as the main antivirus.

5. 5

   Do not stop there

   A scan that finds nothing does not prove the PC is clean if a remote access tool was running. If you pasted a command and ran it, the safest end of the plan is still to back up documents and reinstall Windows.

If you use a Mac, an iPhone or an Android phone

The ps1 tag points at Windows. We found nothing that says the three files run on anything else.
