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...

Want to know what's the latest and greatest in SecOps for 2024? Gartner's recently released Hype Cycle for Security Operations report takes important steps to organize and mature the domain of Continuous Threat Exposure Management, aka CTEM. Three categories within this domain are included in this year's report: Threat Exposure Management, Exposure Assessment Platforms (EAP), and Adversarial Exposure Validation (AEV). These category definitions are aimed at providing some structure to the evolving landscape of exposure management technologies. Pentera, listed as a sample vendor in the newly defined AEV category, is playing a pivotal role in increasing the adoption of CTEM, with a focus on security validation. Following is our take on the CTEM related product categories and what they mean for enterprise security leaders. The Industry is Maturing CTEM, coined by Gartner in 2022, presents a structural approach for continuously assessing, prioritizing, validating, and remediating expo...

Details have emerged about a now-patched vulnerability in Microsoft 365 Copilot that could enable the theft of sensitive user information using a technique called ASCII smuggling. " ASCII Smuggling is a novel technique that uses special Unicode characters that mirror ASCII but are actually not visible in the user interface," security researcher Johann Rehberger said . "This means that an attacker can have the [large language model] render, to the user, invisible data, and embed them within clickable hyperlinks. This technique basically stages the data for exfiltration!" The entire attack strings together a number of attack methods to fashion them into a reliable exploit chain. This includes the following steps - Trigger prompt injection via malicious content concealed in a document shared on the chat to seize control of the chatbot Using a prompt injection payload to instruct Copilot to search for more emails and documents, a technique called automatic too...

Google has revealed that a security flaw that was patched as part of a software update rolled out last week to its Chrome browser has come under active exploitation in the wild. Tracked as CVE-2024-7965 , the vulnerability has been described as an inappropriate implementation bug in the V8 JavaScript and WebAssembly engine. "Inappropriate implementation in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page," according to a description of the bug in the NIST National Vulnerability Database (NVD). A security researcher who goes by the online pseudonym TheDog has been credited with discovering and reporting the flaw on July 30, 2024, earning them a bug bounty of $11,000. Additional specifics about the nature of the attacks exploiting the flaw or the identity of the threat actors that may be utilizing it have not been released. The tech giant, however, acknowledged that it's aware of the ...

SonicWall has released security updates to address a critical flaw impacting its firewalls that, if successfully exploited, could grant malicious actors unauthorized access to the devices. The vulnerability, tracked as CVE-2024-40766 (CVSS score: 9.3), has been described as an improper access control bug. "An improper access control vulnerability has been identified in the SonicWall SonicOS management access, potentially leading to unauthorized resource access and in specific conditions, causing the firewall to crash," the company said in an advisory released last week. "This issue affects SonicWall Firewall Gen 5 and Gen 6 devices, as well as Gen 7 devices running SonicOS 7.0.1-5035 and older versions." The issue has been addressed in the below versions - SOHO (Gen 5 Firewalls) - 5.9.2.14-13o Gen 6 Firewalls - 6.5.2.8-2n (for SM9800, NSsp 12400, and NSsp 12800) and 6.5.4.15.116n (for other Gen 6 Firewall appliances) SonicWall said the vulnerability is ...

The Dutch Data Protection Authority (DPA) has fined Uber a record €290 million ($324 million) for allegedly failing to comply with European Union (E.U.) data protection standards when sending sensitive driver data to the U.S. "The Dutch DPA found that Uber transferred personal data of European taxi drivers to the United States (U.S.) and failed to appropriately safeguard the data with regard to these transfers," the agency said . The data protection watchdog said the move constitutes a "serious" violation of the General Data Protection Regulation (GDPR). In response, the ride-hailing, courier, and food delivery service has ended the practice. Uber is believed to have collected drivers' sensitive information and retained it on U.S.-based servers for over two years. This included account details and taxi licenses, location data, photos, payment details, and identity documents. In some cases, it also contained criminal and medical data of drivers. The DPA accu...

Nowadays, sensitive and critical data is traveling in everyday business channels that offer only the basic level of security and encryption, and companies are often oblivious to the risk. A case in point: Disney suffered a devastating data leak by a hacktivist group known as NullBulge that got hold of over 1.2 terabytes of data from Disney's internal Slack messaging channels. The breach exposed sensitive information, including: details about unreleased projects, computer code, login details and passwords, and Intellectual Property (IP) and corporate secrets. Slack breaches have also impacted companies like Uber, Rockstar, and Electronic Arts (EA). Cisco Webex used by the German Bundeswehr leaked data from hundreds of meetings, some classified. Outlook was breached by Chinese hackers last year. We have nothing against any of the tools above. They are all great collaboration tools. However, just like companies don't allow developers to use just any old tool to push code to p...

Cybersecurity researchers are warning about the security risks in the machine learning (ML) software supply chain following the discovery of more than 20 vulnerabilities that could be exploited to target MLOps platforms. These vulnerabilities, which are described as inherent- and implementation-based flaws, could have severe consequences, ranging from arbitrary code execution to loading malicious datasets. MLOps platforms offer the ability to design and execute an ML model pipeline, with a model registry acting as a repository used to store and version-trained ML models. These models can then be embedded within an application or allow other clients to query them using an API (aka model-as-a-service). "Inherent vulnerabilities are vulnerabilities that are caused by the underlying formats and processes used in the target technology," JFrog researchers said in a detailed report. Some examples of inherent vulnerabilities include abusing ML models to run code of the attacker...

Two security vulnerabilities have been disclosed in the open-source Traccar GPS tracking system that could be potentially exploited by unauthenticated attackers to achieve remote code execution under certain circumstances. Both the vulnerabilities are path traversal flaws and could be weaponized if guest registration is enabled, which is the default configuration for Traccar 5, Horizon3.ai researcher Naveen Sunkavally said. A brief description of the shortcomings is as follows - CVE-2024-24809 (CVSS score: 8.5) - Path Traversal: 'dir/../../filename' and unrestricted upload of file with dangerous type CVE-2024-31214 (CVSS score: 9.7) - Unrestricted file upload vulnerability in device image upload could lead to remote code execution "The net result of CVE-2024-31214 and CVE-2024-24809 is that an attacker can place files with arbitrary content anywhere on the file system," Sunkavally said . "However an attacker only has partial control over the filename....

Cybersecurity researchers have uncovered new Android malware that can relay victims' contactless payment data from physical credit and debit cards to an attacker-controlled device with the goal of conducting fraudulent operations. The Slovak cybersecurity company is tracking the novel malware as NGate, stating it observed the crimeware campaign targeting three banks in Czechia. The malware "has the unique ability to relay data from victims' payment cards, via a malicious app installed on their Android devices, to the attacker's rooted Android phone," researchers Lukáš Štefanko and Jakub Osmani said in an analysis. The activity is part of a broader campaign that has been found to target financial institutions in Czechia since November 2023 using malicious progressive web apps (PWAs) and WebAPKs. The first recorded use of NGate was in March 2024. The end goal of the attacks is to clone near-field communication (NFC) data from victims' physical payment ca...

Pavel Durov, founder and chief executive of the popular messaging app Telegram, was arrested in France on Saturday, according to French television network TF1. Durov is believed to have been apprehended pursuant to a warrant issued in connection with a preliminary police investigation. TF1 said the probe was focused on a lack of content moderation on the instant messaging service, which the authorities took issue with, turning the app into a haven for various kinds of criminal activity, including drug trafficking, child pornography, money laundering, and fraud. The hands-off approach to moderation on Telegram has been a point of contention , fueling cybercrime and turning the platform into a hub for threat actors to organize their operations, distribute malware, and peddle stolen data and other illegal goods  "This messaging app has transformed into a bustling hub where seasoned cybercriminals and newcomers alike exchange illicit tools and insights creating a dark and well-...

Cybersecurity researchers have uncovered a new stealthy piece of Linux malware that leverages an unconventional technique to achieve persistence on infected systems and hide credit card skimmer code. The malware, attributed to a financially motivated threat actor, has been codenamed sedexp by Aon's Stroz Friedberg incident response services team. "This advanced threat, active since 2022, hides in plain sight while providing attackers with reverse shell capabilities and advanced concealment tactics," researchers Zachary Reichert, Daniel Stein, and Joshua Pivirotto said . It's not surprising that malicious actors are constantly improvising and refining their tradecraft, and have turned to novel techniques to evade detection. What makes sedexp noteworthy is its use of udev rules to maintain persistence. Udev, a replacement for the Device File System, offers a mechanism to identify devices based on their properties and configure rules to respond when there is a ch...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has placed a security flaw impacting Versa Director to its Known Exploited Vulnerabilities ( KEV ) catalog based on evidence of active exploitation. The medium-severity vulnerability, tracked as CVE-2024-39717 (CVSS score: 6.6), is case of file upload bug impacting the "Change Favicon" feature that could allow a threat actor to upload a malicious file by masquerading it as a seemingly harmless PNG image file. "The Versa Director GUI contains an unrestricted upload of file with dangerous type vulnerability that allows administrators with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin privileges to customize the user interface," CISA said in an advisory. "The 'Change Favicon' (Favorite Icon) enables the upload of a .png file, which can be exploited to upload a malicious file with a .PNG extension disguised as an image." However, a successful exploitation is poss...

Meta Platforms on Friday became the latest company after Microsoft, Google, and OpenAI to expose the activities of an Iranian state-sponsored threat actor, who it said used a set of WhatsApp accounts that attempted to target individuals in Israel, Palestine, Iran, the U.K., and the U.S. The activity cluster, which originated from Iran, "appeared to have focused on political and diplomatic officials, and other public figures, including some associated with administrations of President Biden and former President Trump," Meta said . The social media giant attributed it to a nation-state actor tracked as APT42, which is also known as Charming Kitten, Damselfly, Mint Sandstorm (formerly Phosphorus), TA453, and Yellow Garuda. It's assessed to be linked to Iran's Islamic Revolutionary Guard Corps (IRGC). The adversarial collective is well-known for its use of sophisticated social engineering lures to spear-phish targets of interest with malware and steal their credenti...

Cybersecurity researchers have uncovered a never-before-seen dropper that serves as a conduit to launch next-stage malware with the ultimate goal of infecting Windows systems with information stealers and loaders. "This memory-only dropper decrypts and executes a PowerShell-based downloader," Google-owned Mandiant said . "This PowerShell-based downloader is being tracked as PEAKLIGHT." Some of the malware strains distributed using this technique are Lumma Stealer , Hijack Loader (aka DOILoader, IDAT Loader, or SHADOWLADDER), and CryptBot , all of which are advertised under the malware-as-a-service (SaaS) model. The starting point of the attack chain is a Windows shortcut (LNK) file that's downloaded via drive-by download techniques -- e.g., when users look up a movie on search engines. It's worth pointing out that the LNK files are distributed within ZIP archives that are disguised as pirated movies. The LNK file connects to a content delivery network...
