Hi there,

We’ve received a notification that one or more of your Droplets at 128.199.194.42 is participating in Brute-force activities. Please note that we may be required to take further action to prevent additional attacks, up to and including suspension of your Droplet. Should we take this step, we'll send an additional email notifying you that we have done this.

You can review the most recent report(s) we received at https://digitalocean.abusehq.net/share/EsFsAYXaHHit-BM2C2aozLPJJYPimxcxk1nednrN82I .

Additionally, you can review the abuse history of this incident at https://digitalocean.abusehq.net/share/RTiVbusRB3SP4GEi-Uj_AQ .

To resolve this matter, you’ll need to review the Droplet to determine the cause of the traffic. The system and application error and access logs may include additional details that could provide more insight on this. Additionally, reviewing your active processes could point to the responsible PID.

Once you’ve discovered the cause, please update this ticket letting us know what you determined to be the cause of the issue, how you resolved it, and what steps you took to prevent further events of a similar nature.

If you have any questions regarding this matter, please let us know.

Regards,

Trust & Safety,
