The importance of email security cannot be understated. Proof of this can be seen in some recent research conducted by the Trustwave SpiderLabs team around our email security product MailMarshal. The team recently ran an experiment on known Zero Day CVE-2023-38831 found in RARLabs WinRAR that is currently being exploited in the wild in WinRAR versions 6.23 and earlier. WinRAR is a compression, archiving, and archive managing software tool.

With an ever-growing number of vulnerabilities being discovered annually, vulnerability management tools are rapidly evolving to handle and prioritize these risks. However, it remains one of the most overwhelming and time-consuming areas in cybersecurity. There’s still significant room for enhancement, especially in reducing false alerts and prioritizing genuine threats.

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.

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.

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.

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.

The Malware-as-a-Service (MaaS) model, and its readily available scheme, remains to be the preferred method for emerging threat actors to carry out complex and lucrative cyberattacks. Information theft is a significant focus within the realm of MaaS, with a specialization in the acquisition and exfiltration of sensitive information from compromised devices, including login credentials, credit card details, and other valuable information.

Snyk is excited to announce general availability of Snyk Apps, a framework for building and distributing custom security solutions to better inform security decisions and boost developer productivity. As Snyk Apps reaches this milestone, Snyk’s Technology Alliance Partnership Program (TAPP) has more than 70 members today.

Breaches were rampant this week, impacting as many as 15 million individuals. The State of Maine announced that it bled 1.3 million resident records due to the global MOVEit vulnerability. Meanwhile, in Ohio, the City of Huber Heights was targeted by a ransomware attack; potentially, 50,000 residents may have their data exposed. In Michigan, the McLaren Health Care network was allegedly attacked by the ransomware gang BlackCat—losing 2.2 million records to exposure.
