(Radio.com) Rolling Stones legend Keith Richards, George Harrison, Sonic Youth and Brett Eldredge are among the many celebrities whose Twitter accounts have recently been hacked. On Tuesday night, a hacker who goes by the handle J5Z took credit for the personal invasions and said he did so to teach the social media community a lesson.

The hacker says musicians and artists are easily hacked and they all need to change their passwords right away. "It's famous musicians and artists at risk," j5Z told The Daily Beast. "If you're a celebrity, you should change your password immediately. Literally everyone should just create a new email, think of a new password, and do it for every account."

At around 2 p.m. on Tuesday, J5Z posted the following on George Harrison's Twitter account: "Hey George, follow @j5zlol when you see this and shoot me a DM. I'll help you secure your accounts I don't want to cause you any harm, bud."

Minutes later, @j5zlol tweeted on his own account, 'Well s- I hacked someone and I didn't even know they was dead.. my bad." Then his account was suspended. A tweet from Harrison's hacked account echoed the sentiment, saying, "SORRY" for not knowing about Harrison's death and adding "IVE BEEN LIVING UNDER A ROCK. MY BAD PPL." Read more here.
