UPDATE: You will see in the comments on this post an update from HubSpot with a link to their blog explaining the incident, I know a lot of folks don’t read the comments, so here it is in full.
“We are very sorry for the mistake. It is completely our fault. As your article mentions, we have contained the situation and stopped the malicious tweets.
We do want to make clear that by design, the HubSpot software applications are on different servers and systems from our free Grader.com tools. This attack did NOT affect the HubSpot software used by our 2,100 customers. Again, there is no impact on our paid product or paying customers.
We have posted an article on our company blog with more information:
- Mike Volpe
HubSpot (makers of Twitter Grader)”
…and that, ladies and gents, is an object lesson in how to deal with an event like this. Much respect to HubSpot.
In what looks like another compromise related to Twitter services, a large number of Twitter users who have granted access to their accounts to the web service Twitter.Grader.com have all begun tweeting a bizarre and unauthorised message.
Fortunately the link that has been endlessly tweeted by grader users does not appear to host any malicious content. It points to a blog with an embedded YouTube video of Biz Stone back in 2006 promoting Twitter.
