Hackers Scanning for Vulnerable Microsoft Exchange Servers

Attackers are actively scanning the internet for Microsoft Exchange Servers vulnerable to the CVE-2020-0688 remote code execution vulnerability patched by Microsoft two weeks ago (despite patches being made available, some organizations choose to forgo automatic updates, opting to implement them manually or not at all). The flaw is present in the Exchange Control Panel (ECP) component and is caused by Exchange's inability to create unique cryptographic keys when being installed.

Despite Widespread Ransomware Concerns, Only 38 Percent of State and Local Government Employees Trained in Prevention

According to the results of a poll recently conducted by IBM, only 38 percent of state and local government employees are trained on ransomware prevention. Additionally, budgets for managing cyber attacks have remained stagnant according to 52 percent of the state and local government IT/security professionals who were polled. These findings were in spite of 73 percent of those polled indicating they are concerned about impending ransomware threats. Additionally, 1 in 6 respondents disclosed their department had been impacted by a ransomware attack.

OpenSMTPD Releases Version 6.6.4p1 to Address a Critical Vulnerability

OpenSMTPD has released version 6.6.4p1 to address a critical vulnerability. A remote attacker could exploit this vulnerability to take control of an affected server. OpenSMTPD is an open-source server-side implementation of the Simple Mail Transfer Protocol (SMTP) that is part of the OpenBSD Project. CISA encourages users and administrators to apply the necessary update.

Building a Digital Defense with Communications

The FBI’s Portland, Oregon office has published an advisory discussing best practices for communications, such as with personal and official email, messaging apps, and social media. As the advisory notes, users should be aware of the potential dangers of cyber attacks through these various channels and of the need to opt for secure methods of communication to reduce the likelihood of intrusion. The advisory groups best practices into encryption, message retention, and access.
