Microsoft addressed vulnerabilities in a dozen of its software products in its Patch Tuesday update for May. And while none of the flaws are currently being exploited, several of the most critical flaws require immediate attention, the company says.
CISA issued a warning to organizations running Pulse Secure VPN servers that their networks may still be vulnerable to hacking even if they applied patches for a previous flaw. Attackers are now using stolen Active Directory credentials to access networks.
Microsoft has released an "out of band" security update to fix a flaw in SMBv3 that was accidentally disclosed publicly before a full fix had been prepared. Security experts warn that the flaw could be exploited to crash vulnerable systems and potentially execute arbitrary code.
From 2016 to 2019, sophisticated nation-state attackers preferred to target 10 vulnerabilities more than all others, the U.S. Cybersecurity and Infrastructure Security Agency and FBI warn in a new alert. They say many of these flaws are years old, yet remain unpatched and actively exploited.
Patch or perish alert: Less than 20 percent of vulnerable Microsoft Exchange servers have received a fix for a serious flaw that Microsoft first disclosed nearly two months ago, security firm Rapid7 warns. It also found a "concerning number" of Exchange 2007 servers, which Microsoft stopped supporting in 2017.
The day after security researcher Patrick Wardle disclosed two zero-day vulnerabilities in the macOS client version of Zoom's teleconferencing platform, the company on Thursday rushed out patches for these flaws and one other.
