In an e-mail sent to customers who have filed a cPanel support request in the past six months, members of the company's security team said they recently discovered the compromise of a server used to process support requests. "While we do not know if your machine is affected, you should change your root level password if you are not already using SSH keys," they wrote, according to a copy of the e-mail posted to a community forum. "If you are using an unprivileged account with 'sudo' or 'su' for root logins, we recommend you change the account password. Even if you are using SSH keys we still recommend rotating keys on a regular basis." The e-mail advised customers to take "immediate action on their own servers," although team members still don't know the exact nature of the compromise. Company representatives didn't respond to an e-mail from Ars asking if they could rule out the possibility that customer names, e-mail addresses, or other personal data were exposed. It's also unclear whether the company followed wide-standing recommendations to cryptographically protect passwords. So-called one-way hashes convert plain-text passwords into long unique strings that can only be reversed using time-consuming cracking techniques. This post will be updated if cPanel representatives respond later.
