A South Korea-aligned cyber espionage has been linked to the zero-day exploitation of a now-patched critical remote code execution flaw in Kingsoft WPS Office to deploy a bespoke backdoor dubbed SpyGlace. The activity has been attributed to a threat actor dubbed APT-C-60 , according to cybersecurity firms ESET and DBAPPSecurity. The attacks have been found to infect Chinese and East Asian users with malware. The security flaw in question is CVE-2024-7262 (CVSS score: 9.3), which stems from a lack of proper validation of user-provided file paths. This loophole essentially allows an adversary to upload an arbitrary Windows library and achieve remote code execution. The bug "allows code execution via hijacking the control flow of the WPS Office plugin component promecefpluginhost.exe," ESET said , adding it found another way to achieve the same effect. The second vulnerability is tracked as CVE-2024-7263 (CVSS score: 9.3). The attack conceived by APT-C-60 weaponizes the...

The threat actors behind the BlackByte ransomware group have been observed likely exploiting a recently patched security flaw impacting VMware ESXi hypervisors, while also leveraging various vulnerable drivers to disarm security protections. "The BlackByte ransomware group continues to leverage tactics, techniques, and procedures (TTPs) that have formed the foundation of its tradecraft since its inception, continuously iterating its use of vulnerable drivers to bypass security protections and deploying a self-propagating, wormable ransomware encryptor," Cisco Talos said in a technical report shared with The Hacker News. The exploitation of CVE-2024-37085 , an authentication bypass vulnerability in VMware ESXi that has also been weaponized by other ransomware groups, is a sign that the e-crime group is pivoting from established approaches. BlackByte made its debut in the second half of 2021 and is purported to be one of the autonomous ransomware offshoots to have emerged...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a critical security flaw affecting the Apache OFBiz open-source enterprise resource planning (ERP) system to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerability, known as CVE-2024-38856, carries a CVSS score of 9.8, indicating critical severity. "Apache OFBiz contains an incorrect authorization vulnerability that could allow remote code execution via a Groovy payload in the context of the OFBiz user process by an unauthenticated attacker," CISA said. Details of the vulnerability first came to light earlier this month after SonicWall described it as a patch bypass for another flaw, CVE-2024-36104, that enables remote code execution via specially crafted requests. "A flaw in the override view functionality exposes critical endpoints to unauthenticated threat actors using a crafted request, paving the way for remote...

Cybersecurity researchers are calling attention to a new QR code phishing (aka quishing) campaign that leverages Microsoft Sway infrastructure to host fake pages, once again highlighting the abuse of legitimate cloud offerings for malicious purposes. "By using legitimate cloud applications, attackers provide credibility to victims, helping them to trust the content it serves," Netskope Threat Labs researcher Jan Michael Alcantara said . "Additionally, a victim uses their Microsoft 365 account that they're already logged-into when they open a Sway page, that can help persuade them about its legitimacy as well. Sway can also be shared through either a link (URL link or visual link) or embedded on a website using an iframe." The attacks have primarily singled out users in Asia and North America, with technology, manufacturing, and finance sectors being the most sought-after sectors. Microsoft Sway is a cloud-based tool for creating newsletters, presentations...

A critical security flaw has been disclosed in the WPML WordPress multilingual plugin that could allow authenticated users to execute arbitrary code remotely under certain circumstances. The vulnerability, tracked as CVE-2024-6386 (CVSS score: 9.9), impacts all versions of the plugin before 4.6.13, which was released on August 20, 2024. Arising due to missing input validation and sanitization, the issue makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server. WPML is a popular plugin used for building multilingual WordPress sites. It has over one million active installations. Security researcher stealthcopter, who discovered and reported CVE-2024-6386, said the problem lies in the plugin's handling of shortcodes that are used to insert post content such as audio, images, and videos. "Specifically, the plugin uses Twig templates for rendering content in shortcodes but fails to properly sanitize input, leadi...

Users of Chinese instant messaging apps like DingTalk and WeChat are the target of an Apple macOS version of a backdoor named HZ RAT . The artifacts "almost exactly replicate the functionality of the Windows version of the backdoor and differ only in the payload, which is received in the form of shell scripts from the attackers' server," Kaspersky researcher Sergey Puzan said . HZ RAT was first documented by German cybersecurity company DCSO in November 2022, with the malware distributed via self-extracting zip archives or malicious RTF documents presumably built using the Royal Road RTF weaponizer . The attack chains involving RTF documents are engineered to deploy the Windows version of the malware that's executed on the compromised host by exploiting a years-old Microsoft Office flaw in the Equation Editor ( CVE-2017-11882 ). The second distribution method, on the other hand, masquerades as an installer for legitimate software such as OpenVPN, PuTTYgen, or E...

The China-nexus cyber espionage group tracked as Volt Typhoon has been attributed with moderate confidence to the zero-day exploitation of a recently disclosed high-severity security flaw impacting Versa Director. The attacks targeted four U.S. victims and one non-U.S. victim in the Internet service provider (ISP), managed service provider (MSP) and information technology (IT) sectors as early as June 12, 2024, the Black Lotus Labs team at Lumen Technologies said in a technical report shared with The Hacker News. The campaign is believed to be ongoing against unpatched Versa Director systems. The security flaw in question is CVE-2024-39717 (CVSS score: 6.6), a file upload bug affecting Versa Director that was added to the Known Exploited Vulnerabilities (KEV) catalog last week by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). "This vulnerability allowed potentially malicious files to be uploaded by users with Provider-Data-Center-Admin or Provider-Data-Ce...
