A previously unknown threat activity cluster targeted European organizations, particularly those in the healthcare sector, to deploy PlugX and its successor, ShadowPad, with the intrusions ultimately leading to deployment of a ransomware called NailaoLocker in some cases. The campaign, codenamed Green Nailao by Orange Cyberdefense CERT, involved the exploitation of a now-patched security flaw in Check Point network gateway security products ( CVE-2024-24919 , CVSS score: 7.5). The attacks were observed between June and October 2024. "The campaign relied on DLL search-order hijacking to deploy ShadowPad and PlugX – two implants often associated with China-nexus targeted intrusions," the company said in a technical report shared with The Hacker News. The initial access afforded by exploitation of vulnerable Check Point instances is said to have allowed the threat actors to retrieve user credentials and to connect to the VPN using a legitimate account. In the next stage,...

Security vulnerabilities have been disclosed in Xerox VersaLink C7025 Multifunction printers (MFPs) that could allow attackers to capture authentication credentials via pass-back attacks via Lightweight Directory Access Protocol ( LDAP ) and SMB/FTP services. "This pass-back style attack leverages a vulnerability that allows a malicious actor to alter the MFP's configuration and cause the MFP device to send authentication credentials back to the malicious actor," Rapid7 security researcher Deral Heiland said . "If a malicious actor can successfully leverage these issues, it would allow them to capture credentials for Windows Active Directory. This means they could then move laterally within an organization's environment and compromise other critical Windows servers and file systems." The identified vulnerabilities, which affect firmware versions 57.69.91 and earlier, are listed below - CVE-2024-12510 (CVSS score: 6.7) - Pass-back attack via LDAP CVE-202...

Network segmentation remains a critical security requirement, yet organizations struggle with traditional approaches that demand extensive hardware investments, complex policy management, and disruptive network changes. Healthcare and manufacturing sectors face particular challenges as they integrate diverse endpoints – from legacy medical devices to IoT sensors – onto their production networks. These devices often lack robust security hardening, creating significant vulnerabilities that traditional segmentation solutions struggle to address. Elisity aims to solve these challenges through an innovative approach that leverages existing network infrastructure while providing identity-based microsegmentation at the network edge. Rather than requiring new hardware, agents or complex network redesigns, Elisity customers run a few lightweight virtual connectors (called Elisity Virtual Edge) to enforce security policies through organizations' current switching infrastructure. In this hands...

Threat actors with suspected ties to China and North Korea have been linked to ransomware and data encryption attacks targeting government and critical infrastructure sectors across the world between 2021 and 2023. While one cluster of activity has been associated with the ChamelGang (aka CamoFei), the second cluster overlaps with activity previously attributed to Chinese and North Korean state-sponsored groups, cybersecurity firms SentinelOne and Recorded Future said in a joint report shared with The Hacker News. This includes ChamelGang's attacks aimed at the All India Institute of Medical Sciences (AIIMS) and the Presidency of Brazil in 2022 using CatB ransomware , as well as those targeting a government entity in East Asia and an aviation organization in the Indian subcontinent in 2023. "Threat actors in the cyber espionage ecosystem are engaging in an increasingly disturbing trend of using ransomware as a final stage in their operations for the purposes of financia...
