Linode Resets Passwords After Credentials Leak (linode.com)

New submitter qmrq sends news that Linode, a major provider of virtual private servers, has been compromised again. In a blog post, they said, "A security investigation into the unauthorized login of three accounts has led us to the discovery of two Linode.com user credentials on an external machine. This implies user credentials could have been read from our database, either offline or on, at some point. The user table contains usernames, email addresses, securely hashed passwords and encrypted two-factor seeds." The Linode team said it found evidence of unauthorized access to three customer accounts. They don't yet know who is behind the attacks.

An employee for PagerDuty said they were compromised through Linode Manager all the way back in July. "In our situation the attacker knew one of our user's passwords and MFA secret. This allowed them to provide valid authentication credentials for an account in the Linode Manager. It's worth noting that all of our active user accounts had two-factor authentication enabled. ... We also have evidence from access logs provided by Linode that the attackers tried to authenticate as an ex-employee, whose username ONLY existed in the Linode database."

    Sounds like someone really hates them. First the DDoS, now the compromise...

    Was this the same event as was reported here two days ago? Or new? The problem here is once your provider has been compromised you have no recourse but to assume that you and your customers who use you have been compromised as well. My guess here is that it is a disgruntled ex-employee of Linode.

    I always find it amusing when a big spammy hosting provider gets pwned. Companies that ignore their spam problems usually tend to ignore their security problems too.

      The relationship between hosting companies and spammers is fascinating. I strongly recommend Krebs book on this topic, it makes for an entertaining and educating read (book is called "Spam Nation").

      Checkout this post on his blog about spammers and IBM:

      Last month, anti-spam group Spamhaus.org listed Softlayer as the “#1 spam hosting ISP,” putting Softlayer at the very top of its World’s Worst Spam Support ISPs index. Spamhaus said the number of abuse issues at the ISP has “rapidly reached rarely previously seen numbers.”

      As a Linode customer, this post was news to me and cause for concern.

      But then I saw that Rackspace had 12:

      and I was glad to have left for Linode after Rackspace bought Slicehost.

      And saw that others were worse, with Dreamhost at 25:

      Seriously? If any of my users does anything even remotely annoying, like running Nmap, I'd immediately get a notification from their netops people. I'd shut the user down, and they'd write back and thank me.

      I can't imagine a spammer lasting very long at all in an environment like that. They take their stuff very seriously there.
