The Cybersecurity and Infrastructure Security Agency is warning organizations to immediately patch the ProxyShell vulnerabilities in Microsoft Exchange email servers because security researchers say ransomware gangs are exploiting these flaws.
Security researchers are tracking several ransomware gangs that are attempting to exploit a series of bugs in Microsoft Windows collectively called "PrintNightmare." Meanwhile, Microsoft has published an out-of-band alert about another zero-day flaw related to the PrintNightmare vulnerabilities.
While the U.S. government is making strides in improving the nation's cybersecurity, it needs to do more to protect critical infrastructure from attacks and create public-private partnerships to improve national security, the Cyberspace Solarium Commission notes in a report published Thursday.
Microsoft's Patch Tuesday rollout addressed two additional security issues within Windows Print Spooler, including one zero-day. Microsoft's August security update covers 44 vulnerabilities, with seven rated critical. Intel and Adobe also made security fixes.
Some patched on-premises Microsoft Exchange email servers are still proving to be vulnerable. The Conti ransomware group is now leveraging backdoors that persist, cybersecurity consulting firm Pondurance reports.
The widely used NicheStack TCP/IP stack has 14 vulnerabilities that, if exploited, could allow for remote code execution, denial of service, information leaks, TCP spoofing or DNS cache poisoning, according to researchers at Forescout and JFrog. But patches are now available.
Researchers at Palo Alto Networks' Unit 42 say they have demonstrated how exploits of Microsoft Jet Database Engine vulnerabilities could lead to remote attacks on Microsoft Internet Information Services and Microsoft SQL Server to gain system privileges. Microsoft recently patched the flaws.
David Brumley, CEO of ForAllSecure, is the creator of Mayhem, a machine that applies patching and continuous penetration testing autonomously and in real time. He discusses software flaw detection and more in this episode of "Cybersecurity Unplugged."
A joint cybersecurity advisory issued by several agencies this week highlighting the ongoing exploits of longstanding software vulnerabilities illustrates the woeful state of patch management, security experts say.
The bug hunting team at pentesting firm Haxolot.com uncovered a remote code execution vulnerability in Moodle, an open-source online learning platform widely used by universities worldwide. The flaw has since been patched.
Ransomware operations continue to thrive thanks to a vibrant cybercrime-as-a-service ecosystem designed to support all manner of online attacks. Given that attackers first need remote access to victims' systems, robust patch management and remote desktop protocol security remain obvious must-have defenses.
Researchers discovered an unauthenticated operating system command injection vulnerability in the Sunhillo SureLine surveillance application that allows an attacker to execute arbitrary commands with root privileges. The flaw has since been patched.
Researchers are warning of three zero-day vulnerabilities in Kaseya's Unitrends cloud-based enterprise backup and disaster recovery technology. The news comes after a July 2 ransomware attack exploiting flaws in Kaseya's VSA software had a major impact.
With corporate America beginning to ask employees to come back to their offices in the fall, cybersecurity teams have the huge task of ensuring that the work environment is safe. This is particularly true of IoT devices, as many have been left unprotected for months.
