Excuse me Sciamannikoo,
I answered you in incorrectly mode. i have disable the mail notification for wp-sentinel.
yes, i have the same alert by wp-sentinel for the ip address 72.233.44.10 and other ips for a attack of the variable “& lt ; ? xml_version”(without white spaces). but only the ip 72.233.44.10 (in my case) is banned in automatic mode.
I suppose that:
1) The function to collect attackers data and build a ip address blacklist in a centralized server of wp-sentinel had record the ip and attack.
It can be a true attack!!!
2) The ip address 72.233.44.10 is owned by Jetpack Site.
I hypothesize that because sometimes i have problem viewing the statistics jetpack in the board.
In this case, it is a problem of wp-sentinel.
Sorry me, but i don’t know other. The author of wp-sentinel plugin should answer these questions, or the Jetpack teem!!
