Rubrik, a cybersecurity company specializing in cloud data management, has revealed that some of its systems were infiltrated by the Clop ransomware group. Rubrik is one of many companies attacked by Clop via an infamous zero-day vulnerability in the GoAnywhere file transfer software.
The attack began in February, according to its CEO Michael Mestrovich. βWe 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,β he says in a blog post published Tuesday. Mestrovich claims that βbased 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.β
He also revealed the attackers compromised internal sales data, including customer and partner company names, business contact information, and some purchase orders from Rubrik distributors. According to Mestrovich, the third-party investigators used by Rubrik confirmed that no personal information, such as Social Security Numbers (SSNs), financial accounts, and payment card numbers, were compromised.
The GoAnywhere vulnerability, tracked as CVE-2023-0669, has a severity rating of High and was included in CISAβs Known Exploited Vulnerabilities Catalog, a list of actively exploited vulnerabilities every federal information system must patch urgently. The catalog is an essential go-to list for IT admins trying to prioritize their patching.
The attack on Rubrik happened before an emergency patch was available.
Clop hasnβt been shy about the 130 organizations itβs stolen data from thanks to the GoAnywhere vulnerability. Last week, the gang began sending out extortion emails to the victims, and adding them to its leak site. Known victims include Rubrik, Hatch Bank and Community Health Systems (CHS).
Organizations using GoAnywhere should download the security patch immediately. Fortra has also provided a technical mitigation in its advisory, which can be accessed via the companyβs customer portal.
