steelstanleystaystrong.top: a server that handed out Linux botnet files, and what to do if a router or camera asked for them

What steelstanleystaystrong.top is, and what we know about it

steelstanleystaystrong.top is a web address, not software you installed. The abuse.ch project URLhaus lists it for a shell script and 13 Linux programs, all reported on one evening, 15 October 2026. We found no public write-up of this exact address, so this page is built from the URLhaus rows we hold, the registration record, one request from our own server, and what security organisations have published about the same kind of file set.

1. 1

   What URLhaus lists

   Fourteen file addresses on steelstanleystaystrong.top. Thirteen sit in a folder called hiddenbin and are named Space followed by a processor name: x86, x86_64, i686, arm, arm5, arm6, arm7, mips, mpsl, ppc, sh4, m68k and arc. The fourteenth is a script called 1.sh in the top folder. All carry the threat label malware_download, the tag botnetdomain and the tag ua-wget, and all were added by the same reporter, NDA0E.

2. 2

   What the tags mean

   botnetdomain means the reporter considers the domain a home for a botnet, a network of hacked devices that obey one controller. elf is the file type of programs on Linux. sh is a shell script. ua-wget means the reporter fetched the files with the wget tool, whose name shows up as the user agent. Nothing in the tags names a malware family.

3. 3

   What we could not confirm

   We did not download any file, so we cannot say what is inside, which family it is, or where it reports to. The 13 file names match the layout of other sample pages on MalwareBazaar (abuse.ch) that are tagged Mirai and are served from a hiddenbin folder on other numeric addresses. That makes a Mirai style botnet loader the likely reading. It is our reading, not a result.

4. 4

   What this means for you

   If the name appeared in a router log, a DNS log or a firewall alert, the device that asked for it is the one in question. A person does not type this address by hand. The risk is for a router, camera, recorder, NAS or small server that was already compromised and went to fetch the script. If you only read the name in a block list, you are not infected by that.

Kind of threat

A server that hosted a loader script and 13 Linux ELF files for different processors, tagged botnetdomain by URLhaus

Where the files were

hxxp://steelstanleystaystrong[.]top/1.sh and hxxp://steelstanleystaystrong[.]top/hiddenbin/Space.x86 (and 12 more Space.* names): plain http

Domain registered

7 August 2026 at 17:23 UTC, registrar Global Domain Group LLC, status client transfer prohibited (RDAP, read 15 October 2026)

URLhaus entries

14 file addresses, all added on 15 October 2026 between 18:52 and 19:07 UTC; all 14 are marked offline in our copy of the data

Our check

One plain request from our server on 17 October 2026: the name could not be resolved (getaddrinfo ENOTFOUND)

Platform

Linux and embedded Linux devices (routers, cameras, recorders). The files are ELF programs, which do not run on Windows, Mac, iPhone or Android as they are

What we checked on 17 October 2026, and what we could not

Our check was a plain request from our own server, not a browser visit. It failed at the first step: the server could not find the address in DNS (error ENOTFOUND). That means the name did not resolve for us on 17 October. It does not clear anything.

What happened to steelstanleystaystrong.top, from registration to our check

The domain is about ten weeks old and the reports come from a single quarter of an hour. Dates come from RDAP and from the URLhaus rows we hold; times are UTC.

1. 7 August 2026

   The domain is registered

   RDAP shows steelstanleystaystrong.top registered on 7 August 2026 at 17:23 UTC through Global Domain Group LLC, with the status client transfer prohibited. That status stops the domain being moved to another registrar by accident or theft; it says nothing about how the domain is used.

2. 15 October 2026, 18:52 UTC

   Thirteen Space files are reported

   Within 16 seconds, from 18:52:17 to 18:52:33, URLhaus adds Space.arm, Space.m68k, Space.arm7, Space.x86_64, Space.ppc, Space.sh4, Space.arm5, Space.arm6, Space.mips, Space.mpsl, Space.i686, Space.arc and Space.x86. All are ELF files in /hiddenbin/, tagged botnetdomain and ua-wget. Such a burst looks like a tool that walks through a file list, not a person.

3. 15 October 2026, 19:07 UTC

   The script 1.sh is reported

   About 15 minutes later the same reporter adds http://steelstanleystaystrong.top/1.sh, tagged sh. It is the only entry that is not an ELF file. A script at the root next to a folder of builds for every processor is the usual shape of a loader that picks the build matching the device.

4. 15 to 17 October 2026

   Everything goes offline

   In our copy of the data all 14 entries are marked offline. On 17 October our server could not resolve the name at all.

   

What the pattern suggests, and what it does not: a domain bought in August and used for malware files in October fits a throwaway address for a campaign. That is our reading of the dates. No report says who runs it, how many devices were infected, or whether the files are live elsewhere.

How a script and thirteen files turn a router into a bot

The set of files tells a story even without opening them. This is how the same pattern is described for Mirai, the best known family of this kind. We did not see this server's files, so treat it as the likely shape, not a proven account.

1. 1

   The device is reached first

   The CIS write-up of Mirai says the malware targets routers, DVRs, IP cameras and Linux servers running BusyBox, and that attackers usually get a shell through default telnet or SSH logins. Later Mirai variants also use known flaws in exposed devices; the SANS Internet Storm Center and SOC Prime describe variants that exploit many vulnerabilities.

2. 2

   A script is pulled with wget

   Once the attacker can type commands on the device, a short script such as 1.sh downloads the next piece. The ua-wget tag shows that this server was asked for its files with wget, which is also installed on many small Linux devices. The SANS ISC describes this style of shell script as a Command and Scripting Interpreter: Unix Shell, technique T1059.004.

3. 3

   The script picks the right build

   Small devices use many different processors. A loader tries one file per type, in turn, until one starts. That is why the folder holds x86, x86_64, i686, arm, arm5, arm6, arm7, mips, mpsl, ppc, sh4, m68k and arc builds. MalwareBazaar lists samples with exactly these Space.* names on other addresses, tagged Mirai.

4. 4

   The program runs from memory and disables rivals

   According to the CIS write-up, Mirai shuts down Telnet, SSH and HTTP on the device so that administrators and other malware cannot log in, and it binds a local port to run only one copy. The CISA alert on Mirai adds that the malware lives in dynamic memory, so a reboot removes it. That is why reinfection happens quickly if the password stays unchanged.

5. 5

   The device joins the botnet

   From then on the device waits for orders from a controller. The reports we read describe denial of service attacks, where thousands of devices flood one target, as the main use. We do not know what the controller behind this domain ordered.

None of this applies to a laptop or a phone running Windows, Mac, iOS or standard Android, because the files are ELF programs built for embedded chips. It does apply to the internet facing boxes in a home or office that nobody updates.

Is it Mirai? What the evidence supports

The honest answer is: likely a Mirai style loader, not proven. We list what points that way and what is missing.

Who can run into this: devices that may have asked for these files

Nobody visits this address on purpose. A device was told to fetch from it. The list below is the kind of device the sources name, not a list of confirmed victims.

1. 1

   A default or weak login reachable from the internet

   The CIS write-up says Mirai relies on default telnet and SSH credentials. A router with remote administration turned on and the password from the sticker is the textbook victim. CISA's December 2023 alert to manufacturers also tells users to change default passwords on routers, firewalls and access points.

2. 2

   A known flaw in an unpatched device

   Some variants skip passwords and use a bug in the web interface or a service. Updating the firmware closes known bugs; a device that no longer gets updates cannot be fixed this way.

3. 3

   A server with a weak SSH login

   A small Linux server on a hosting plan can be reached the same way. If you run one, the log of failed and successful sign ins is the first place to look.

What this can cost you

Reading the address costs nothing. The risks below apply to a device that was compromised and joined a botnet. Botnet bots rarely read your files; they use your connection.

• High

  Your device is used to attack others

  A bot sends traffic to targets chosen by the controller. Your address can end up in attack logs and on block lists.

• Medium

  A slow or unstable connection

  Attack traffic uses your upload speed. Streaming, calls and games may stutter while the device is busy.

• Medium

  The device is locked to you

  Mirai style malware closes Telnet, SSH and web access to keep others out, so you may suddenly be unable to open the router page or the camera app.

• Medium

  A way into the rest of your network

  A compromised router or camera sits inside your network. We found no report that these files go further, but an attacker with a foothold there can try.

• Low

  Nothing, if you only saw the name

  A name in a log or a warning is not an infection. It tells you a device asked, so find that device.

What you may notice, and what you may not

Most owners notice nothing. The signs below come from the sources or follow from them; none is certain.

Start with one question: which device asked for steelstanleystaystrong.top, and when? A router log, a DNS filter, a firewall alert or a hosting provider's abuse notice normally names the source. If you have no such record, treat the reachable devices on the network as the ones to review.

None of the checks below deletes anything. Write down what you see before you change it.

1. 1

   Find the source in your log

   Open the log or event page of your router, firewall or DNS service and search for steelstanleystaystrong.top and for hiddenbin. Note the device name or local address and the time. A DNS log shows which machine asked; a router log may only show the router itself.

2. 2

   Look at what is open to the internet

   In the router's settings look for remote administration, port forwarding and UPnP. Anything that lets the internet reach Telnet (port 23), SSH (port 22) or the web page of the device is a way in. Turn off what you do not use.

3. 3

   Try the login

   If the device page used to open and now does not, or the usual password stopped working, that fits a takeover, but it can also be a fault. Do not guess more passwords on the live network.

4. 4

   On a Linux server, list processes and files

   Run ps aux and look for programs you do not know, especially from /tmp, /var/tmp or /dev/shm. Run ls -la /tmp. Check the user's crontab with crontab -l and the sign in log (journalctl -u ssh or the auth log). Programs named Space.something, or a file called 1.sh you did not create, are reason to disconnect.

5. 5

   Check your other devices for the same name

   Search the same log for other local addresses that asked for the name. More than one source means more than one device to clean.

6. 6

   A clean result does not clear it

   No log entry may only mean the log is short or the request went through another path. Treat any compromise sign as real, and a clean look as one data point.

How to clean a router, camera or other small Linux device

The order below follows the CISA alert on Mirai and the CIS guidance, which say to disconnect, reboot, change the password and keep the device off the open internet. Exact menus differ by maker, so use your device's manual for the screens. We did not infect a device to test this.

1. 1

   Disconnect the device

   Pull the network cable and turn off Wi-Fi on the device. The CISA alert says to disconnect first, so the controller cannot reach it and it cannot be reinfected.

2. 2

   Reboot it while it is offline

   Because Mirai lives in dynamic memory, the CISA alert says a reboot clears it. Power the device off, wait a minute, and turn it on again, still without a network connection.

3. 3

   Change the password before you reconnect

   The CISA alert warns that a device reconnected with the default password can be reinfected quickly. Set a long, unique password for the device login and for the Wi-Fi. Connect a laptop directly to the device if you need to reach its page.

4. 4

   Update the firmware

   Download the newest firmware from the maker's own site and install it. A US government guide for IoT users advises signing up for automatic updates where the maker offers them. If the maker no longer offers updates, plan to replace the device.

5. 5

   Close remote login from the internet

   Turn off remote administration, Telnet and UPnP unless you need them. FBI guidance quoted with the Mirai alert advises blocking inbound ports 23, 2323 and 103 at the firewall or gateway.

6. 6

   Reconnect and watch the log

   Plug it back in and watch the log for several days. If the device again asks for steelstanleystaystrong.top or another strange address, it is compromised again.

7. 7

   If it keeps coming back, reset or replace

   Use the maker's factory reset, set up the device again from scratch and apply the first four steps before it touches the internet. If the device is old and has no updates, buying a new one is the safe answer.

8. 8

   On a Linux server, rebuild from a clean image

   If you found unknown programs or sign ins on a hosting server, the safest path is a fresh install from a trusted image, restoring only your data. Change all keys and passwords that were on the server and add key based SSH login with passwords disabled.

If you own a server that was used to host these files

Some addresses on lists like this belong to a hacked site, not to the attacker. We have no evidence that steelstanleystaystrong.top was a hacked third party site; it looks like a domain registered for this purpose. If you own a domain or server where files like these turned up, the steps below apply.

1. 1

   Do not delete the evidence first

   Copy the web folder and the logs to a safe place before you clean. The access log shows when the files appeared and which login or flaw was used.

2. 2

   Find how the files got there

   Look for outdated content management software, weak admin or FTP passwords and exposed management panels. Change every password and key, and update the software.

3. 3

   Remove the files and the backdoor

   Delete the hiddenbin folder and 1.sh, and look for other unknown files and scheduled tasks. A rebuild from a clean backup is safer than hand cleaning.

4. 4

   Ask for a re-check

   When the server is clean, tell your host. Blocking services normally re-test an address after the listed files are gone.

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

The 13 files are ELF programs for embedded Linux processors. They do not run on a desktop or phone as they are, and we found no source that says this server affected them.
