Kaseya Discovers Vulnerability that Allows Monero Mining

It has long been speculated that the recent increase in network hashrate was due to botnets and the increase in GPU sales, with the focus on botnet activity. It was recently discovered that there may be some bad actors at work taking advantage of a vulnerability in the popular workstation management application, Kaseya.

Here is the January 2018 VSA Security Update posted on their Announcements Page:

In the course of our continuous security monitoring of our products, we have uncovered a security vulnerability in our VSA product.

Consistent with our commitment to providing secure solutions for our partners, we have issued a set of patches that removes this vulnerability. We strongly recommend that every on-premises VSA customer download and install this patch immediately.  The patch to address this vulnerability has already been deployed to our SaaS and hosted servers.

We have seen no evidence to suggest that this vulnerability was used to harvest personal, financial, or other sensitive information.  However, we are aware of a small subset of our partners where Monero cryptocurrency mining software was deployed to endpoints.  Our initial estimates indicate that less than 0.1% of our customers have been affected by this issue.
