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...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Apple has released security updates for iOS, iPadOS, macOS, visionOS, and its Safari web browser to address two zero-day flaws that have come under active exploitation in the wild. The flaws are listed below - CVE-2024-44308 (CVSS score: 8.8)  - A vulnerability in JavaScriptCore that could lead to arbitrary code execution when processing malicious web content CVE-2024-44309 (CVSS score: 6.1)  - A cookie management vulnerability in WebKit that could lead to a cross-site scripting (XSS) attack when processing malicious web content The iPhone maker said it addressed CVE-2024-44308 and CVE-2024-44309 with improved checks and improved state management, respectively.  Not much is known about the exact nature of the exploitation, but Apple has acknowledged that the pair of vulnerabilities "may have been actively exploited on Intel-based Mac systems." Clément Lecigne and Benoît Sevens of Google's Threat Analysis Group (TAG) have been credited with discovering and report...

Threat actors with ties to the Democratic People's Republic of Korea (DPRK aka North Korea) have been found embedding malware within Flutter applications, marking the first time this tactic has been adopted by the adversary to infect Apple macOS devices. Jamf Threat Labs, which made the discovery based on artifacts uploaded to the VirusTotal platform earlier this month, said the Flutter-built applications are part of a broader activity that includes malware written in Golang and Python. It's currently not known how these samples are distributed to victims, and if it has been used against any targets, or if the attackers are switching to a new delivery method. That said, North Korean threat actors are known to engage in extensive social engineering efforts targeting employees of cryptocurrency and decentralized finance businesses. "We suspect these specific examples are testing," Jaron Bradley, director at Jamf Threat Labs, told The Hacker News. "It's p...

A threat actor with ties to the Democratic People's Republic of Korea (DPRK) has been observed targeting cryptocurrency-related businesses with a multi-stage malware capable of infecting Apple macOS devices . Cybersecurity company SentinelOne, which dubbed the campaign Hidden Risk , attributed it with high confidence to BlueNoroff, which has been previously linked to malware families such as RustBucket , KANDYKORN , ObjCShellz , RustDoor (aka Thiefbucket ), and TodoSwift . The activity "uses emails propagating fake news about cryptocurrency trends to infect targets via a malicious application disguised as a PDF file," researchers Raffaele Sabato, Phil Stokes, and Tom Hegel said in a report shared with The Hacker News. "The campaign likely began as early as July 2024 and uses email and PDF lures with fake news headlines or stories about crypto-related topics." As revealed by the U.S. Federal Bureau of Investigation (FBI) in a September 2024 advisory, the...

Threat actors are leveraging fake Google Meet web pages as part of an ongoing malware campaign dubbed ClickFix to deliver infostealers targeting Windows and macOS systems. "This tactic involves displaying fake error messages in web browsers to deceive users into copying and executing a given malicious PowerShell code, finally infecting their systems," French cybersecurity company Sekoia said in a report shared with The Hacker News. Variations of the ClickFix (aka ClearFake and OneDrive Pastejacking) campaign have been reported widely in recent months , with threat actors employing different lures to redirect users to bogus pages that aim to deploy malware by urging site visitors to run an encoded PowerShell code to address a supposed issue with displaying content in the web browser. These pages are known to masquerade as popular online services, including Facebook, Google Chrome, PDFSimpli, and reCAPTCHA, and now Google Meet as well as potentially Zoom - meet.googl...

Microsoft has disclosed details about a now-patched security flaw in Apple's Transparency, Consent, and Control (TCC) framework in macOS that has likely come under exploitation to get around a user's privacy preferences and access data. The shortcoming, codenamed HM Surf by the tech giant, is tracked as CVE-2024-44133 (CVSS score: 5.5). It was addressed by Apple as part of macOS Sequoia 15 by removing the vulnerable code. HM Surf "involves removing the TCC protection for the Safari browser directory and modifying a configuration file in the said directory to gain access to the user's data, including browsed pages, the device's camera, microphone, and location, without the user's consent," Jonathan Bar Or of the Microsoft Threat Intelligence team said . Microsoft said the new protections are limited to Apple's Safari browser, and that it's working with other major browser vendors to further explore the benefits of hardening local configuration file...

Threat actors with ties to North Korea have been observed using poisoned Python packages as a way to deliver a new malware called PondRAT as part of an ongoing campaign. PondRAT, according to new findings from Palo Alto Networks Unit 42, is assessed to be a lighter version of POOLRAT (aka SIMPLESEA), a known macOS backdoor that has been previously attributed to the Lazarus Group and deployed in attacks related to the 3CX supply chain compromise last year. Some of these attacks are part of a persistent cyber attack campaign dubbed Operation Dream Job , wherein prospective targets are lured with enticing job offers in an attempt to trick them into downloading malware. "The attackers behind this campaign uploaded several poisoned Python packages to PyPI, a popular repository of open-source Python packages," Unit 42 researcher Yoav Zemah said , linking the activity with moderate confidence to a threat actor called Gleaming Pisces. The adversary is also tracked by the wid...

Eight vulnerabilities have been uncovered in Microsoft applications for macOS that an adversary could exploit to gain elevated privileges or access sensitive data by circumventing the operating system's permissions-based model, which revolves around the Transparency, Consent, and Control ( TCC ) framework. "If successful, the adversary could gain any privileges already granted to the affected Microsoft applications," Cisco Talos said . "For example, the attacker could send emails from the user account without the user noticing, record audio clips, take pictures, or record videos without any user interaction." The shortcomings span various applications such as Outlook, Teams, Word, Excel PowerPoint, and OneNote. The cybersecurity company said malicious libraries could be injected into these applications and gain their entitlements and user-granted permissions, which could then be weaponized for extracting sensitive information depending on the access granted ...

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...

Cybersecurity researchers have uncovered a new information stealer that's designed to target Apple macOS hosts and harvest a wide range of information, underscoring how threat actors are increasingly setting their sights on the operating system. Dubbed Cthulhu Stealer, the malware has been available under a malware-as-a-service (MaaS) model for $500 a month from late 2023. It's capable of targeting both x86_64 and Arm architectures. "Cthulhu Stealer is an Apple disk image (DMG) that is bundled with two binaries, depending on the architecture," Cado Security researcher Tara Gould said . "The malware is written in Golang and disguises itself as legitimate software." Some of the software programs it impersonates include CleanMyMac, Grand Theft Auto IV, and Adobe GenP, the last of which is an open-source tool that patches Adobe apps to bypass the Creative Cloud service and activates them without a serial key. Users who end up launching the unsigned file af...

Cybersecurity researchers have uncovered a new macOS malware strain dubbed TodoSwift that they say exhibits commonalities with known malicious software used by North Korean hacking groups. "This application shares several behaviors with malware we've seen that originated in North Korea (DPRK) — specifically the threat actor known as BlueNoroff — such as KANDYKORN and RustBucket ," Kandji security researcher Christopher Lopez said in an analysis. RustBucket, which first came to light in July 2023, refers to an AppleScript-based backdoor that's capable of fetching next-stage payloads from a command-and-control (C2) server. Late last year, Elastic Security Labs also uncovered another macOS malware tracked as KANDYKORN that was deployed in connection with a cyber attack targeting blockchain engineers of an unnamed cryptocurrency exchange platform. Delivered by means of a sophisticated multi-stage infection chain, KANDYKORN possesses capabilities to access and exfi...

Microsoft on Thursday disclosed four medium-severity security flaws in the open-source OpenVPN software that could be chained to achieve remote code execution (RCE) and local privilege escalation (LPE). "This attack chain could enable attackers to gain full control over targeted endpoints, potentially resulting in data breaches, system compromise, and unauthorized access to sensitive information," Vladimir Tokarev of the Microsoft Threat Intelligence Community said . That said, the exploit, presented by Black Hat USA 2024, requires user authentication and an advanced understanding of OpenVPN's inner workings. The flaws affect all versions of OpenVPN prior to version 2.6.10 and 2.5.10. The list of vulnerabilities is as follows - CVE-2024-27459 - A stack overflow vulnerability leading to a Denial-of-service (DoS) and LPE in Windows CVE-2024-24974 - Unauthorized access to the "\\openvpn\\service" named pipe in Windows, allowing an attacker to remotely inte...

Apple on Tuesday announced an update to its next-generation macOS version that makes it a little more difficult for users to override Gatekeeper protections. Gatekeeper is a crucial line of defense built into macOS designed to ensure that only trusted apps run on the operating system. When an app is downloaded from outside of the App Store and opened for the first time, it verifies that the software is from an identified developer. It also runs checks to ensure that the app is notarized and has not been tampered with to install malware on macOS systems. Furthermore, it requires user approval before allowing any such third-party app to be run. It's this user approval mechanism that Apple has now tightened further with macOS Sequoia, the next iteration of the Mac operating system that's expected to be released next month. "In macOS Sequoia, users will no longer be able to Control-click to override Gatekeeper when opening software that isn't signed correctly or no...

Cybersecurity researchers have discovered a malicious package on the Python Package Index (PyPI) repository that targets Apple macOS systems with the goal of stealing users' Google Cloud credentials from a narrow pool of victims. The package, named "lr-utils-lib," attracted a total of 59 downloads before it was taken down. It was uploaded to the registry in early June 2024. "The malware uses a list of predefined hashes to target specific macOS machines and attempts to harvest Google Cloud authentication data," Checkmarx researcher Yehuda Gelb said in a Friday report. "The harvested credentials are sent to a remote server." An important aspect of the package is that it first checks if it has been installed on a macOS system, and only then proceeds to compare the system's Universally Unique Identifier (UUID) against a hard-coded list of 64 hashes. If the compromised machine is among those specified in the predefined set, it attempts to access...

Cybersecurity researchers have discovered an updated variant of a known stealer malware that attackers affiliated with the Democratic People's Republic of Korea (DPRK) have delivered as part of prior cyber espionage campaigns targeting job seekers. The artifact in question is an Apple macOS disk image (DMG) file named "MiroTalk.dmg" that mimics the legitimate video call service of the same name, but, in reality, serves as a conduit to deliver a native version of BeaverTail, security researcher Patrick Wardle said . BeaverTail refers to a JavaScript stealer malware that was first documented by Palo Alto Networks Unit 42 in November 2023 as part of a campaign dubbed Contagious Interview that aims to infect software developers with malware through a supposed job interview process. Securonix is tracking the same activity under the moniker DEV#POPPER . Besides siphoning sensitive information from web browsers and crypto wallets, the malware is capable of delivering addi...
