Cybersecurity Threat Advisory: Office 365 Zero-Day Attacks

Microsoft released a mitigation for a vulnerability that exists in the Windows 10 operating system that can be exploited against Office 365 and Office 2019. Identified as CVE-2021-40444, this vulnerability could allow attackers to execute arbitrary code on a device if exploited. Because Microsoft Office is used and trusted by millions worldwide, attackers potentially could launch very-large-scale attacks; accordingly, this vulnerability has a severity rating of 8.8 out of 10. Recommendations from Mission Critical Partners to prevent devices from becoming susceptible to this vulnerability are below.

Essential Tactics for Enhancing Cybersecurity in Today’s Justice Organizations

In my previous blog on cybersecurity, I provided a high-level perspective on the cybersecurity environment for justice organizations today. I noted that the environment is worrisome — it is a virtual certainty that cyberattackers, at this very moment, are looking for a way to infiltrate your organization’s networks and systems.

But I promised a progression (crawl, walk, run) that you can employ immediately to quickly begin thwarting cyberattackers and protecting your networks and systems, as well as the critical data and applications that run on them. This strategy is based on industry best practices and thought leadership to which MCP has actively contributed.^[1]

Implementing a Cybersecurity Training Program is the First Line of Defense

Cybersecurity has become a huge problem for any organization that is operating networks and/or systems, but especially so for those in the government sector, particularly public-safety and justice agencies.

Are Cloud-Based Solutions Right for Your Agency?

A lot of people in the public safety/justice/public sector sectors are talking about cloud-based solutions these days. It is easy to understand why there is so much chatter because solutions that live in the cloud offer some impressive benefits. Here are just a few:

• Cloud-based solutions typically offer best-of-breed technologies and services
• Cloud-based solutions remove the maintenance and upgrade burden from the end user from a technology perspective
• Cloud-based solutions often make it easier to share resources regionally or even broader compared with siloed, on-premises solutions
• Cloud-based solutions typically offer enhanced resiliency and redundancy compared with on-premises solutions
• Cloud-based solutions often make it easier for agencies to transfer operations to another location in “bug out” scenarios
• Cloud-based solutions are easier and faster to scale —both up and down, based on the agency’s needs at any given juncture — compared with on-premises solutions
• Cloud-based solutions typically are more secure, because providers often have greater information technology and cybersecurity resources and assets to draw upon

This week there is a new critical alert that requires the mission-critical community’s immediate attention.

Advisory overview

Qualys’s research team discovered a pair of vulnerabilities in the Linux operating system (OS). While one is a local privilege escalation (LPE) vulnerability, the other is a stack-exhaustion, denial-of-service (DOS) vulnerability in the system. Both can be exploited by an unauthorized user. Both vulnerabilities affect an integral part of the Linux operating system, which increases the need for remediation. A patch has been released for both vulnerabilities and should be immediately applied.

Cybersecurity Threat Advisory: 'PrintNightmare' Zero-Day Vulnerability in Windows Print Spooler

This week there is a new alert that requires the mission-critical community’s immediate attention.

Advisory Overview

Last week, security researchers mistakenly published proof-of-concept (PoC) exploit code, which has since been dubbed “PrintNightmare.” The vulnerability exploits a critical flaw in Microsoft’s print spooler service. Microsoft has issued out-of-band security updates to address the flaw and has rated it as critical as attackers can remotely execute code with system-level privileges on affected machines.

This Month’s Cyberchat Shines a Light on the Rise of Ransomware

Earlier this year, we ramped up our cybersecurity efforts by launching a series of monthly video chats in which we summarize the most recent threats, share information from entities such as the Federal Bureau of Investigation (FBI) and the Cybersecurity Infrastructure Security Agency (CISA), and offer tips for preventing cyberattacks and mitigating them if they occur. This month’s Cyberchat video, which can be viewed below, contains some important information that public-sector and critical infrastructure agencies need to have.

Double the Attack, Double the Fees

Double-encryption ransomware attacks, which typically include cyberattackers encrypting a target’s data twice, at the same time or shortly after each other, are on the rise. In this month’s video, we explore how agencies can mitigate the risk of a double-encryption attack and begin the rebuilding process if one occurs.

Next Week’s CAPS Explores Public-Safety Opportunities & Challenges

Having attended dozens of educational conferences over the decade that I served as editor-in-chief of Urgent Communications and Fire Chief magazines, I know an excellent one when I see it—and I can report without fear of contradiction that the second-annual Conference for Advancing Public Safety (CAPS)—being presented by Mission Critical Partners (MCP) on June 15-16—is shaping up to be an excellent educational event.

Liability Is Another Critical Reason to Be Prudent About Cybersecurity

Cyberattacks should be on the radar of every agency in the public-safety/justice community. One of the most prevalent attacks involves ransomware, which is a specific type of malware that cyberattackers use to exploit a system vulnerability and then launch a program that encrypts the organization’s data files, essentially locking them and rendering them unusable. The cyberattacker then demands a ransom—hence the name—to provide the key that unlocks the files.
