Microsoft Corp. is investigating reports that attackers are exploiting two previously unknown vulnerabilities in Exchange Server, a technology many organizations rely on to send and receive email. Microsoft says it is expediting work on software patches to plug the security holes. In the meantime, it is urging a subset of Exchange customers to enable a setting that could help mitigate ongoing attacks.

The "ProxyNotShell" security vulnerabilities can be chained for remote code execution and total takeover of corporate email platforms.

Gentoo Linux Security Advisory 202209-23 - Multiple vulnerabilities have been found in Chromium and its derivatives, the worst of which could result in remote code execution. Versions less than 105.0.5195.125 are affected.

Multiple cross-site scripting (XSS) vulnerabilities in Canon Medical Vitrea View 7.x before 7.7.6 allow remote attackers to inject arbitrary web script or HTML via (1) the input after the error subdirectory to the /vitrea-view/error/ subdirectory, or the (2) groupID, (3) offset, or (4) limit parameter to an Administrative Panel (Group and Users) page. There is a risk of an attacker retrieving patient information.

Reports to the National Vulnerability Database jumped in 2022, but we should pay just as much attention to the flaws that are not being reported to NVD, including those affecting the software supply chain.

An espionage-focused threat actor has been observed using a steganographic trick to conceal a previously undocumented backdoor in a Windows logo in its attacks against Middle Eastern governments. Broadcom's Symantec Threat Hunter Team attributed the updated tooling to a hacking group it tracks under the name Witchetty, which is also known as LookingFrog, a subgroup operating under the TA410

A social engineering campaign leveraging job-themed lures is weaponizing a years-old remote code execution flaw in Microsoft Office to deploy Cobalt Strike beacons on compromised hosts. "The payload discovered is a leaked version of a Cobalt Strike beacon," Cisco Talos researchers Chetan Raghuprasad and Vanja Svajcer said in a new analysis published Wednesday. "The beacon configuration contains

A "highly operational, destructive, and sophisticated nation-state activity group" with ties to North Korea has been weaponizing open source software in their social engineering campaigns aimed at companies around the world since June 2022. Microsoft's threat intelligence teams, alongside LinkedIn Threat Prevention and Defense, attributed the intrusions with high confidence to Zinc, which is
