> Microsoft’s Threat Intelligence team has said that Storm-0558, a China-based hacking outfit that conducts espionage on behalf of that country’s government, exploited them starting on May 15. Microsoft drove out the attackers on June 16 after a customer tipped off company researchers of the intrusion. By then, Storm-0558 had breached accounts belonging to 25 organizations.

Looks like it was a couple of months ago.
