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.

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.

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.

Network and system endpoints, i.e., workstations and servers, are the most vulnerable network and system elements because they directly interface with the applications that we use. Those applications act as gateways into those endpoints and thus are used by cyberattackers to deliver the malware that will enable them to carry out their nefarious missions. This is especially true of ransomware, which targets files and data that are accessible on or from those endpoints. The cyberattacker’s goal is to gain access and control of as many endpoints as possible.

As part of our effort to inform our clients about potential and serious cybersecurity issues, MCP provides advisories about vulnerabilities and exploits that could threaten the operations of their critical communications networks. Sign up to receive these advisories in your inbox as soon as they are released.

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

Advisory overview

Microsoft’s Patch Tuesday release for May 2021 includes a Windows update that will remediate a multitude of vulnerabilities. The update will patch 55 vulnerabilities; one is critical, 50 are important, and one is moderate. It also includes patches for three zero-day vulnerabilities that are identified below. MCP recommends updating all Windows machines to apply these patches and remediate the vulnerabilities.
