In our modern world, we constantly share private, confidential, and sensitive information over digital channels. A fundamental component of this communication is file encryption — transforming data into an unreadable format using encryption algorithms.

On November 21st, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Multi-State Information Sharing & Analysis Center (MS-ISAC), and Australian Signals Directorate’s Australian Cyber Security Center (ASD’s ACSC) released an advisory highlighting the ongoing exploit of the Citrix Bleed Vulnerability (CVE-2023-4966) by Lockbit 3.0 affiliates.

In 2022, more than 25,000 new CVEs were discovered and added to the NIST National Vulnerability Database. In just the first ten months of 2023, another 23,500 CVEs were identified and added to the NIST NVD. That’s more than 48,000 new vulnerabilities documented in less than 2 years! With so many new CVEs being identified all the time, vulnerability management can seem like an insurmountable challenge. Despite the staggering numbers, there’s good news.

Since 2005, the Common Vulnerability Scoring System (CVSS) has been used to assess and communicate the severity of vulnerabilities in software. If you’re involved in cybersecurity, even if you’re not directly involved in managing vulnerabilities, you’ve probably come across CVSS designations like ‘critical’ or ‘high’ when referring to vulnerabilities in the industry.

On November 16, 2023, a significant security concern was published by Google's Threat Analysis Group (TAG). They revealed an alarming vulnerability in Zimbra Collaboration, a widely-used email hosting tool for organizations. This vulnerability, designated with an identifier, CVE-2023-37580, is a glaring example of a reflected cross-site scripting (XSS) issue. It allows malicious scripts to be injected into unsuspecting users' browsers through a deceptively simple method: clicking on a harmful link.
