Rubrik, the Silicon Valley data security company, said that it experienced a network intrusion made possible by a zero-day vulnerability in a product it used called GoAnywhere.

In an advisory posted on Tuesday, Rubrik CISO Michael Mestrovich said an investigation into the breach found that the intruders gained access to mainly internal sales information, including company names and contact information, and a limited number of purchase orders from Rubrik distributors. The investigation, which was aided by an unnamed third-party company, concluded there was no exposure of sensitive information such as Social Security numbers, financial account numbers, or payment card data.

Tight-lipped

“We detected unauthorized access to a limited amount of information in one of our non-production IT testing environments as a result of the GoAnywhere vulnerability,” Mestrovich wrote. “Importantly, based on our current investigation, being conducted with the assistance of third-party forensics experts, the unauthorized access did NOT include any data we secure on behalf of our customers via any Rubrik products.”
