Anybody experienced a site hack last couple of days

[einstein]

Hi Folks,

I just checked my site and its hacked. it only shows this site is hacked by kabul.
I dont think its happened because of this plugin but i just wanted to check and make sure.
Cos i have only 3-4 plugins installed at my site . and all of them including s2memeber were up to date at the time of exploit.

Best regards,

Venura
