Mandrill says some email-related data may have been exposed after attackers tried to lasso some of its servers into a botnet. Data doesn’t appear to have been stolen, but some customers should take some security precautions. Mandrill discovered the vulnerability on March 10 after attackers unsuccessfully tried logging into those internal logging servers. Customers who used Mandrill’s SMTP integration should deactivate all API (application programming interface) keys and generate new ones as a precaution, Mandrill said in a blog post.”]
