The Wordfence Web Application Firewall has blocked 125 attacks over the last 10 minutes.

Wordfence is blocking these attacks, and we're sending this notice to make you aware that there is a higher volume of the attacks than usual. Additionally, the Wordfence Real-Time IP Blocklist can block known attackers' IP addresses automatically for Premium users, including any probing requests that may not be malicious on their own. All Wordfence users can also opt to block the attacking IPs manually if desired. As always, be sure to watch your scan results and keep your plugins, themes and WordPress core version updated.

Below is a sample of these recent attacks:
