afraid guild member is hacked

Hello, Im making this Thread about "Hunkatank" level 60 UD rogue in the guild Swedish Jazz Orchestra
He was away this weekend from friday-sunday, on sunday around 12.00 Server time he logged on, i wrote to him, no reply and he logged off.
Then at 17.00 server time he whispered me that he couldnt log into his mainaccount and that he ( was on his alt on another acc ) saw he was online some hours ago, i confirmed this and now we are afraid hes hacked. i made a Ticket about this, but the GM wanted us to talk to a higher "ranked" GM but i had to log to go to bed
So the main reason i make this thread is so we can get it confirmed his password has been changed, since hes unaviable to log into his account on Nostalrius.org and in-game. and to prevent him getting banned due to this.
according to himself he downloaded a spreadsheet that didnt work some days prior to this.
hopefully he can just do a retrieve password in 10-days and everything is good
