Cybersecurity researchers have disclosed details of a new vulnerability impacting Google's Quick Share data transfer utility for Windows that could be exploited to achieve a denial-of-service (DoS) or send arbitrary files to a target's device without their approval. The flaw, tracked as CVE-2024-10668 (CVSS score: 5.9), is a bypass for two of the 10 shortcomings that were originally disclosed by SafeBreach Labs in August 2024 under the name QuickShell . It has been addressed in Quick Share for Windows version 1.0.2002.2 following responsible disclosure in August 2024. A consequence of these 10 vulnerabilities, collectively tracked as CVE-2024-38271 (CVSS score: 5.9) and CVE-2024-38272 (CVSS score: 7.1), was that they could have been fashioned into an exploit chain to obtain arbitrary code execution on Windows hosts. Quick Share (previously Nearby Share) is a peer-to-peer file-sharing utility similar to Apple AirDrop that allows users to transfer files, photos, videos, a...

Broadcom has issued security patches to address a high-severity security flaw in VMware Tools for Windows that could lead to an authentication bypass.

Cybersecurity researchers are alerting to a new campaign that leverages web injects to deliver a new Apple macOS malware known as FrigidStealer . The activity has been attributed to a previously undocumented threat actor known as TA2727, with the information stealers for other platforms such as Windows ( Lumma Stealer or DeerStealer ) and Android ( Marcher ). TA2727 is a "threat actor that uses fake update themed lures to distribute a variety of malware payloads," the Proofpoint Threat Research Team said in a report shared with The Hacker News.  It's one of the newly identified threat activity clusters alongside TA2726, which is assessed to be a malicious traffic distribution system (TDS) operator that facilitates traffic distribution for other threat actors to deliver malware. The financially motivated threat actor is believed to be active since at least September 2022. TA2726, per the enterprise security firm, acts as a TDS for TA2727 and another threat actor ca...

Microsoft on Tuesday released fixes for 63 security flaws impacting its software products, including two vulnerabilities that it said has come under active exploitation in the wild. Of the 63 vulnerabilities, three are rated Critical, 57 are rated Important, one is rated Moderate, and two are rated Low in severity. This is aside from the 23 flaws Microsoft addressed in its Chromium-based Edge browser since the release of last month's Patch Tuesday update . The update is notable for fixing two actively exploited flaws - CVE-2025-21391 (CVSS score: 7.1) - Windows Storage Elevation of Privilege Vulnerability  CVE-2025-21418 (CVSS score: 7.8) - Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability "An attacker would only be able to delete targeted files on a system," Microsoft said in an alert for CVE-2025-21391. "This vulnerability does not allow disclosure of any confidential information, but could allow an attacker to delete d...

An analysis of HellCat and Morpheus ransomware operations has revealed that affiliates associated with the respective cybercrime entities are using identical code for their ransomware payloads. The findings come from SentinelOne, which analyzed artifacts uploaded to the VirusTotal malware scanning platform by the same submitter towards the end of December 2024. "These two payload samples are identical except for victim specific data and the attacker contact details," security researcher Jim Walter said in a new report shared with The Hacker News. Both HellCat and Morpheus are nascent entrants to the ransomware ecosystem, having emerged in October and December 2024, respectively. A deeper examination of the Morpheus/HellCat payload, a 64-bit portable executable, has revealed that both samples require a path to be specified as an input argument. They are both configured to exclude the \Windows\System32 folder, as well as a hard-coded list of extensions from the encryp...

A little-known cyber espionage actor known as The Mask has been linked to a new set of attacks targeting an unnamed organization in Latin America twice in 2019 and 2022. "The Mask APT is a legendary threat actor that has been performing highly sophisticated attacks since at least 2007," Kaspersky researchers Georgy Kucherin and Marc Rivero said in an analysis published last week. "Their targets are usually high-profile organizations, such as governments, diplomatic entities, and research institutions." Also known as Careto, the threat actor was previously documented by the Russian cybersecurity company over a decade ago in February 2014 as having targeted over 380 unique victims since 2007. The origins of the hacking group are currently unknown. Initial access to target networks is facilitated by means of spear-phishing emails embedding links to malicious websites that are designed to trigger browser-based zero-day exploits to infect the visitor (e.g., CVE-...

A newly devised technique leverages a Windows accessibility framework called UI Automation (UIA) to perform a wide range of malicious activities without tipping off endpoint detection and response (EDR) solutions. "To exploit this technique, a user must be convinced to run a program that uses UI Automation," Akamai security researcher Tomer Peled said in a report shared with The Hacker News. "This can lead to stealthy command execution, which can harvest sensitive data, redirect browsers to phishing websites, and more." Even worse, local attackers could take advantage of this security blindspot to execute commands and read/write messages from/to messaging applications like Slack and WhatsApp. On top of that, it could also be potentially weaponized to manipulate UI elements over a network. First available in Windows XP as part of the Microsoft .NET Framework, UI Automation is designed to provide programmatic access to various user interface (UI) elements and h...

Microsoft closed out its Patch Tuesday updates for 2024 with fixes for a total of 72 security flaws spanning its software portfolio, including one that it said has been exploited in the wild. Of the 72 flaws, 17 are rated Critical, 54 are rated Important, and one is rated Moderate in severity. Thirty-one of the vulnerabilities are remote code execution flaws, and 27 of them allow for the elevation of privileges. This is in addition to 13 vulnerabilities the company has addressed in its Chromium-based Edge browser since the release of last month's security update . In total, Microsoft has resolved as many as 1,088 vulnerabilities in 2024 alone, per Fortra. The vulnerability that Microsoft has acknowledged as having been actively exploited is CVE-2024-49138 (CVSS score: 7.8), a privilege escalation flaw in the Windows Common Log File System (CLFS) Driver. "An attacker who successfully exploited this vulnerability could gain SYSTEM privileges," the company said in an...

Cybersecurity researchers have warned of a new scam campaign that leverages fake video conferencing apps to deliver an information stealer called Realst targeting people working in Web3 under the guise of fake business meetings. "The threat actors behind the malware have set up fake companies using AI to make them increase legitimacy," Cado Security researcher Tara Gould said . "The company reaches out to targets to set up a video call, prompting the user to download the meeting application from the website, which is Realst infostealer." The activity has been codenamed Meeten by the security company, owing to the use of names such as Clusee, Cuesee, Meeten, Meetone, and Meetio for the bogus sites. The attacks entail approaching prospective targets on Telegram to discuss a potential investment opportunity, urging them to join a video call hosted on one of the dubious platforms. Users who end up on the site are prompted to download a Windows or macOS version dep...

Cybersecurity researchers have disclosed a set of flaws impacting Palo Alto Networks and SonicWall virtual private network (VPN) clients that could be potentially exploited to gain remote code execution on Windows and macOS systems. "By targeting the implicit trust VPN clients place in servers, attackers can manipulate client behaviours, execute arbitrary commands, and gain high levels of access with minimal effort," AmberWolf said in an analysis. In a hypothetical attack scenario, this plays out in the form of a rogue VPN server that can trick the clients into downloading malicious updates that can cause unintended consequences. The result of the investigation is a proof-of-concept (PoC) attack tool called NachoVPN that can simulate such VPN servers and exploit the vulnerabilities to achieve privileged code execution. The identified flaws are listed below - CVE-2024-5921 (CVSS score: 5.6) - An insufficient certificate validation vulnerability impacting Palo Alto N...

A newly patched security flaw impacting Windows NT LAN Manager (NTLM) was exploited as a zero-day by a suspected Russia-linked actor as part of cyber attacks targeting Ukraine. The vulnerability in question, CVE-2024-43451 (CVSS score: 6.5), refers to an NTLM hash disclosure spoofing vulnerability that could be exploited to steal a user's NTLMv2 hash. It was patched by Microsoft earlier this week. "Minimal interaction with a malicious file by a user such as selecting (single-click), inspecting (right-click), or performing an action other than opening or executing could trigger this vulnerability," Microsoft revealed in its advisory. Israeli cybersecurity company ClearSky, which discovered the zero-day exploitation of the flaw in June 2024, said it's been abused as part of an attack chain that delivers the open-source Spark RAT malware. "The vulnerability activates URL files, leading to malicious activity," the company said, adding the malicious file...
