Nation State Hackers Exploiting Zero-Day in Roundcube Webmail Software

Oct 25, 2023 Threat Intelligence / Vulnerability
The threat actor known as  Winter Vivern  has been observed exploiting a zero-day flaw in Roundcube webmail software on October 11, 2023, to harvest email messages from victims' accounts. "Winter Vivern has stepped up its operations by using a zero-day vulnerability in Roundcube," ESET security researcher Matthieu Faou  said  in a new report published today. Previously, it was using known vulnerabilities in Roundcube and Zimbra, for which proofs-of-concept are available online." Winter Vivern, also known as TA473 and UAC-0114, is an  adversarial collective  whose objectives align with that of Belarus and Russia. Over the past few months, it has been attributed to attacks against Ukraine and Poland, as well as government entities across Europe and India. The group is also assessed to have exploited another flaw Roundcube as recently as August and September (CVE-2020-35730), making it the  second nation-state group after APT28  to target the open-source webmail so
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
