Hello, Codeforces.↵
↵
Today, my friend and teammate [user:jiangshibiao,2018-08-27] was going to register for the round, but discovered that his Codeforces account was hacked and the avatar as well as the password has been changed. The email could be changed too, but he is unsure right now. I looked at the avatar and immediately noticed it was the same as [user:[user:im0qianqian],2018-08-27]'s avatar, who made a [blog post](https://codeforces.net/blog/entry/61363) about his account being hacked too. ↵
↵
I think probably the same hacker did it, and there may be more victims. So I would like to invite [user:MikeMirzayanov,2018-08-27] to look into the issue and possibly help my friend get his account back. Also, I would advise users who have weak passwords to change the password immediately.↵

Also, [user:jiangshibiao,2018-08-27] and me are onsite at Petrozavodsk Camp right now, so maybe someone can meet him in person if needed to verify his identify.↵
↵
#### UPD Aug. 29:↵
↵
The hacker sent me [a message](https://imgur.com/a/d6FZFwa) in Chinese with the account of [user:im0qianqian,2018-08-29] claiming that he changed the password and the email back. Then [user:im0qianqian,2018-08-29] sent me another message saying that he got his account back and the previous message wasn't sent by him. Unfortunately, my friend [user:jiangshibiao,2018-08-29] tried the original password but it still does not work, and he forgot what email address was used when registering his account. Therefore he is still locked out of his account. Any help from Codeforces administration is still greatly appreciated.↵
