December 5, 2024Ravi LakshmananIoT Vulnerability / Security Cyber security researchers have released a proof-of-concept (PoC) exploit that combines a patched critical security flaw affecting Mitel MiCollab with arbitrary zero-day file reading, allowing an attacker to access files from susceptible instances. The critical vulnerability in question is CVE-2024-41713 (CVSS Score: 9.8), which relates to insufficient input validation in Mitel MiCollab’s NuPoint Unified Messaging (NPM) component, leading to an attack bypassing the path. MiCollab is a software and hardware solution which integrates chat, voice, video and SMS messaging with Microsoft Teams and other apps. NPM is a voice mail server systemwhich allows…
Duplicated previously undocumented threat cluster Land of the Minotaur uses the MOONSHINE exploit suite and an unregistered Android and Windows backdoor called DarkNimbus to facilitate long-term surveillance operations against Tibetans and Uighurs. “Earth Minotaur uses MOONSHINE to deliver the DarkNimbus backdoor to Android and Windows devices, targeting WeChat and potentially making it a cross-platform threat,” Trend Micro researchers Joseph Chen and Daniel Lungi said in an analysis published today. “MOONSHINE exploits many known vulnerabilities in Chromium-based browsers and applications, requiring users to regularly update their software to prevent attacks.” Countries affected by Earth Minotaur attacks include Australia, Belgium, Canada, France,…
Vulnerability management (VM) has long been a cornerstone of an organization’s cybersecurity. Almost as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. In recent years, however, the limitations of this approach have become increasingly apparent. In essence, vulnerability management processes remain important for identifying and remediating flaws. But with the passage of time and the development of attack paths, this approach is starting to show its age. In a recent report, How to turn vulnerability management into impact management (Gartner, How to Turn Vulnerability Management…
December 5, 2024Ravi LakshmananThreat Intelligence / Cyber Espionage A suspected Chinese threat actor targeted a major US organization earlier this year as part of a four-month intrusion. According to Broadcom-owned Symantec, the first evidence of malicious activity was discovered on April 11, 2024, and continued through August.

December 5, 2024Ravi LakshmananCyber espionage / malware The China-linked threat known as MirrorFace has been attributed to a new phishing campaign since June 2024, mainly targeting individuals and organizations in Japan. The purpose of the campaign is to spread backdoors known as NOOPDOOR (aka HiddenFace) and SORRY (aka UPPERCOTT), Trend Micro’s technical analysis says. “An interesting aspect of this campaign is the return of a backdoor called ANEL that was used in campaigns targeting Japan APT10 until around 2018 and has not been observed since then,” said security researcher Hara Hiroaki said. It should be noted that MirrorFace also used…
