Cybersecurity researchers are calling attention to an Android malware campaign that leverages Microsoft's .NET Multi-platform App UI (.NET MAUI) framework to create bogus banking and social media apps targeting Indian and Chinese-speaking users. "These threats disguise themselves as legitimate apps, targeting users to steal sensitive information," McAfee Labs researcher Dexter Shin said . .NET MAUI is Microsoft's cross-platform desktop and mobile app framework for creating native applications using C# and XAML. It represents an evolution of Xamarin, with added capabilities to not only create multi-platform apps using a single project, but also incorporate platform-specific source code as and when necessary. It's worth noting that official support for Xamarin ended on May 1, 2024 , with the tech giant urging developers to migrate to .NET MAUI. While Android malware implemented using Xamarin has been detected in the past , the latest development signals that ...

A ransomware-as-a-service (RaaS) operation called VanHelsing has already claimed three victims since it launched on March 7, 2025, demanding ransoms as high as $500,000. "The RaaS model allows a wide range of participants, from experienced hackers to newcomers, to get involved with a $5,000 deposit. Affiliates keep 80% of the ransom payments, while the core operators earn 20%," Check Point said in a report published over the weekend. "The only rule is not to target the Commonwealth of Independent States (CIS)." As with any affiliate-backed ransomware program, VanHelsing claims to offer the ability to target a wide range of operating systems, including Windows, Linux, BSD, Arm, and ESXi. It also employs what's called the double extortion model of stealing data prior to encryption and threatening to leak the information unless the victim pays up. The RaaS operators have also revealed that the scheme offers a control panel that works "seamlessly" o...

Identity-based attacks are on the rise. Attackers are targeting identities with compromised credentials, hijacked authentication methods, and misused privileges. While many threat detection solutions focus on cloud, endpoint, and network threats, they overlook the unique risks posed by SaaS identity ecosystems. This blind spot is wreaking havoc on heavily SaaS-reliant organizations big and small. The question is, what can security teams do about it? Have no fear, because Identity Threat Detection and Response (ITDR) is here to save the day. It's essential to have the visibility and response mechanisms to stop attacks before they become breaches. Here's the super lineup that every team needs to stop SaaS identity threats. #1 Full coverage: cover every angle  Like Cap's shield, this defense should cover every angle. Traditional threat detection tools such as XDRs and EDRs fail to cover SaaS applications and leave organizations vulnerable. SaaS identity threat detection and re...

Cybersecurity researchers have uncovered two malicious extensions in the Visual Studio Code (VSCode) Marketplace that are designed to deploy ransomware that's under development to its users. The extensions, named "ahban.shiba" and "ahban.cychelloworld," have since been taken down by the marketplace maintainers. Both the extensions, per ReversingLabs , incorporate code that's designed to invoke a PowerShell command, which then grabs a PowerShell-script payload from a command-and-control (C2) server and executes it. The payload is suspected to be ransomware in early-stage development, only encrypting files in a folder called "testShiba" on the victim's Windows desktop. Once the files are encrypted, the PowerShell payload displays a message, stating "Your files have been encrypted. Pay 1 ShibaCoin to ShibaWallet to recover them." However, no other instructions or cryptocurrency wallet addresses are provided to the victims, anothe...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...

The GSM Association (GSMA) has formally announced support for end-to-end encryption (E2EE) for securing messages sent via the Rich Communications Services (RCS) protocol, bringing much-needed security protections to cross-platform messages shared between Android and iOS platforms. To that end, the new GSMA specifications for RCS include E2EE based on the Messaging Layer Security (MLS) protocol via what's called the RCS Universal Profile 3.0 . "The new specifications define how to apply MLS within the context of RCS," Tom Van Pelt, technical director of GSMA, said . "These procedures ensure that messages and other content such as files remain confidential and secure as they travel between clients." This also means that RCS will be the first "large-scale messaging service" to have support for interoperable E2EE between different client implementations from different providers in the near future. It's worth noting that Google's own implemen...

Browser maker Mozilla is urging users to update their Firefox instances to the latest version to avoid facing issues with using add-ons due to the impending expiration of a root certificate. "On March 14, 2025, a root certificate used to verify signed content and add-ons for various Mozilla projects, including Firefox, will expire," Mozilla said . "Without updating to Firefox version 128 or higher (or ESR 115.13 + for ESR users, including Windows 7/8/8.1 and macOS 10.12-10.14 users), this expiration may cause significant issues with add-ons, content signing, and DRM-protected media playback." Mozilla said the latest version of Firefox includes a new root certificate that will prevent this from happening. The update is crucial for all users of Firefox running a version prior to 128, or Extended Support Release (ESR) versions before 115.13, both of which were released on July 9, 2024. This includes all versions of Firefox for Windows, macOS, Linux, and Android...

Cyber threats today don't just evolve—they mutate rapidly, testing the resilience of everything from global financial systems to critical infrastructure. As cybersecurity confronts new battlegrounds—ranging from nation-state espionage and ransomware to manipulated AI chatbots—the landscape becomes increasingly complex, prompting vital questions: How secure are our cloud environments? Can our IoT devices be weaponized unnoticed? What happens when cybercriminals leverage traditional mail for digital ransom? This week's events reveal a sobering reality: state-sponsored groups are infiltrating IT supply chains, new ransomware connections are emerging, and attackers are creatively targeting industries previously untouched. Moreover, global law enforcement actions highlight both progress and persistent challenges in countering cybercrime networks. Dive into this edition to understand the deeper context behind these developments and stay informed about threats that continue reshap...

Threat hunters have shed light on a "sophisticated and evolving malware toolkit" called Ragnar Loader that's used by various cybercrime and ransomware groups like Ragnar Locker (aka Monstrous Mantis), FIN7, FIN8, and Ruthless Mantis (ex-REvil). "Ragnar Loader plays a key role in keeping access to compromised systems, helping attackers stay in networks for long-term operations," Swiss cybersecurity company PRODAFT said in a statement shared with The Hacker News. "While it's linked to the Ragnar Locker group, it's unclear if they own it or just rent it out to others. What we do know is that its developers are constantly adding new features, making it more modular and harder to detect." Ragnar Loader, also referred to as Sardonic, was first documented by Bitdefender in August 2021 in connection with an unsuccessful attack carried out by FIN8 aimed at an unnamed financial institution located in the U.S. It's said to have been put to use ...

Brazil, South Africa, Indonesia, Argentina, and Thailand have become the targets of a campaign that has infected Android TV devices with a botnet malware dubbed Vo1d . The improved variant of Vo1d has been found to encompass 800,000 daily active IP addresses, with the botnet scaling a peak of 1,590,299 on January 19, 2025, spanning 226 countries and regions. As of February 25, 2025, India has experienced a notable surge in infection rate, increasing from less than 1% (3,901) to 18.17% (217,771).  "Vo1d has evolved to enhance its stealth, resilience, and anti-detection capabilities," QiAnXin XLab said . "RSA encryption secures network communication, preventing [command-and-control] takeover even if [the Domain Generation Algorithm] domains are registered by researchers. Each payload uses a unique Downloader, with XXTEA encryption and RSA-protected keys, making analysis harder." The malware was first documented by Doctor Web in September 2024 as affecting Androi...

The threat actor known as Space Pirates has been linked to a malicious campaign targeting Russian information technology (IT) organizations with a previously undocumented malware called LuckyStrike Agent. The activity was detected in November 2024 by Solar, the cybersecurity arm of Russian state-owned telecom company Rostelecom. It's tracking the activity under the name Erudite Mogwai. The attacks are also characterized by the use of other tools like Deed RAT , also called ShadowPad Light, and a customized version of proxy utility named Stowaway , which has been previously used by other China-linked hacking groups. "Erudite Mogwai is one of the active APT groups specializing in the theft of confidential information and espionage," Solar researchers said . "Since at least 2017, the group has been attacking government agencies, IT departments of various organizations, as well as enterprises related to high-tech industries such as aerospace and electric power....

Passwords are rarely appreciated until a security breach occurs; suffice to say, the importance of a strong password becomes clear only when faced with the consequences of a weak one. However, most end users are unaware of just how vulnerable their passwords are to the most common password-cracking methods. The following are the three common techniques for cracking passwords and how to defend against them. Brute force attack Brute force attacks are straightforward yet highly effective techniques for cracking passwords. These attacks involve malicious actors using automated tools to systematically try every possible password combination through repeated login attempts. While such tools have existed for years, the advent of affordable computing power and storage has made them even more efficient today, especially when weak passwords are used. How it works When it comes to brute force attacks, malicious actors employ a range of tactics—from simple brute force attacks that test ev...
