Upload files

Using the REST API to upload a file to WordPress is quite simple. All you need is to send the file in a POST-Request to the wp/v2/media route.

There are two ways of sending a file. The first method simply sends the file in the body of the request. The following PHP script shows the basic principle:

<?php

$args = array(
  'label' => '', // Text in Label
  'class' => '',
  'style' => '',
  'wrapper_class' => '',
  'value' => '', // if empty, retrieved from post meta where id is the meta_key
  'id' => '', // required
  'name' => '', //name will set from id if empty

Failed attempts by username:
grep "Invalid user " /var/log/auth.log | cut -d' ' -f8 | awk '{a[$0]++}END{for(i in a)print i,a[i]}' | sort -k 2 -n -r | head -n 100

IP address of each attempt:
grep "Invalid user " /var/log/auth.log | cut -d' ' -f10 | awk '{a[$0]++}END{for(i in a)print i,a[i]}' | sort -k 2 -n -r | head -n 100

Filter for brute-force interactive SSH logins:
grep sshd.\*Failed /var/log/auth.log | less

Look for failed connections (i.e. no login attempted, could be a port scanner, etc.):
