Cloud software giant Salesforce.com just warned its customers of a new software attack that may be targeting its users.
The malware is called Dyre — and sometimes also Dyreza — and it typically goes after customers of large financial institutions. Salesforce says it may now be used to attack users of its software, though it has no evidence that any of its customers have been affected yet.
According to this blog post by security researcher Jérôme Segura of Malwarebytes, the malware comes in the form of an email attachment and seeks to steal login credentials like user names and passwords by recording keystrokes.
That means that Salesforce itself is not vulnerable — there has been no hacking attack on its systems in this case. Instead, the attack is similar to someone trying to hijack your Gmail or Dropbox account.
Salesforce is recommending that IT departments require employees to log in via corporate VPNs and add two-factor authentication.
Its full statement on the situation is here, and also pasted in full below.
On September 3, 2014, one of our security partners identified that the Dyre malware (also known as Dyreza), which typically targets customers of large, well-known financial institutions, may now also target some Salesforce users. We currently have no evidence that any of our customers have been impacted by this, and we are continuing our investigation. If we determine that a customer has been impacted by this malware, we will reach out to them with next steps and further guidance.
This is not a vulnerability within Salesforce. It is malware that resides on infected computer systems and is designed to steal user log-in credentials and resides on infected customer systems.
