Bloog

Thanks @programmerbear – I’ll certainly try out Mailbard when I get the time. (So far, your previous fix has worked well).

This issue is also being discussed at the WP forum for MailPoet Newsletters (previous)

Adding a captcha has so far blocked this particular exploit, but I agree with Programmerbear that Mailpoet seem not to be taking the issue very seriously (it’s not so long since they were asking users to stop requesting recaptcha support…)

The targets of the attack and IPs so far match the first two stated in Programmerbear’s blog post.

The most recent archive.org crawl might help while the wiki is offline.
