An international operation coordinated by Europol has disrupted the infrastructure of a pro-Russian hacktivist group known as NoName057(16) that has been linked to a string of distributed denial-of-service (DDoS) attacks against Ukraine and its allies. The actions have led to the dismantling of a major part of the group's central server infrastructure and more than 100 systems across the world. The joint effort also included two arrests in France and Spain, searches of two dozen homes in Spain, Italy, Germany, the Czech Republic, France and Poland, and the issuance of arrest warrants for six Russian nationals. The effort, codenamed Operation Eastwood, took place between July 14 and 17, and involved authorities from Czechia, France, Finland, Germany, Italy, Lithuania, Poland, Spain, Sweden, Switzerland, the Netherlands, and the United States. The investigation was also supported by Belgium, Canada, Estonia, Denmark, Latvia, Romania and Ukraine. NoName057(16) has been operatio...

Cisco has disclosed a new maximum-severity security vulnerability impacting Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) that could permit an attacker to execute arbitrary code on the underlying operating system with elevated privileges. Tracked as CVE-2025-20337, the shortcoming carries a CVSS score of 10.0 and is similar to CVE-2025-20281 , which was patched by the networking equipment major late last month. "Multiple vulnerabilities in a specific API of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying operating system as root. The attacker does not require any valid credentials to exploit these vulnerabilities," the company said in an updated advisory. "These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities by submitting a crafted API request. A successful exploit could allow the att...

Cybersecurity researchers have flagged a new variant of a known malware loader called Matanbuchus that packs in significant features to enhance its stealth and evade detection. Matanbuchus is the name given to a malware-as-a-service (MaaS) offering that can act as a conduit for next-stage payloads , including Cobalt Strike beacons and ransomware. First advertised in February 2021 on Russian-speaking cybercrime forums for a rental price of $2,500, the malware has been put to use as part of ClickFix-like lures to trick users visiting legitimate-but-compromised sites not running it. Matanbuchus's delivery methods have evolved over time, leveraging phishing emails pointing to booby-trapped Google Drive links, drive-by downloads from compromised sites, malicious MSI installers , and malvertising . It has been used to deploy a variety of secondary payloads including DanaBot, QakBot, and Cobalt Strike, all known precursors to ransomware deployment. The latest version of the loade...

A threat activity cluster has been observed targeting fully-patched end-of-life SonicWall Secure Mobile Access (SMA) 100 series appliances as part of a campaign designed to drop a backdoor called OVERSTEP . The malicious activity, dating back to at least October 2024, has been attributed by the Google Threat Intelligence Group (GTIG) to a hacking crew it tracks as UNC6148 . The number of known victims is "limited" at this stage. The tech giant assessed with high confidence that the threat actor is "leveraging credentials and one-time password (OTP) seeds stolen during previous intrusions, allowing them to regain access even after organizations have applied security updates." "Analysis of network traffic metadata records suggests that UNC6148 may have initially exfiltrated these credentials from the SMA appliance as early as January 2025." The exact initial access vector used to deliver the malware is currently not known due to the steps taken by the...

Social engineering attacks have entered a new era—and they're coming fast, smart, and deeply personalized. It's no longer just suspicious emails in your spam folder. Today's attackers use generative AI, stolen branding assets, and deepfake tools to mimic your executives, hijack your social channels, and create convincing fakes of your website, emails, and even voice. They don't just spoof— they impersonate. Modern attackers aren't relying on chance. They're running long-term, multi-channel campaigns across email, LinkedIn, SMS, and even support portals—targeting your employees, customers, and partners. Whether it's a fake recruiter reaching out on LinkedIn, a lookalike login page sent via text, or a cloned CFO demanding a wire transfer, the tactics are faster, more adaptive, and increasingly automated using AI. The result? Even trained users are falling for sophisticated fakes—because they're not just phishing links anymore. They're operations. This Webinar Shows You How to Fight...

Google on Tuesday revealed that its large language model (LLM)-assisted vulnerability discovery framework discovered a security flaw in the SQLite open-source database engine before it could have been exploited in the wild. The vulnerability, tracked as CVE-2025-6965 (CVSS score: 7.2), is a memory corruption flaw affecting all versions prior to 3.50.2. It was discovered by Big Sleep , an artificial intelligence (AI) agent that was launched by Google last year as part of a collaboration between DeepMind and Google Project Zero. "An attacker who can inject arbitrary SQL statements into an application might be able to cause an integer overflow resulting in read off the end of an array," SQLite project maintainers said in an advisory. The tech giant described CVE-2025-6965 as a critical security issue that was "known only to threat actors and was at risk of being exploited." Google did not reveal who the threat actors were. "Through the combination of threa...

Governmental organizations in Southeast Asia are the target of a new campaign that aims to collect sensitive information by means of a previously undocumented Windows backdoor dubbed HazyBeacon . The activity is being tracked by Palo Alto Networks Unit 42 under the moniker CL-STA-1020 , where "CL" stands for "cluster" and "STA" refers to "state-backed motivation." "The threat actors behind this cluster of activity have been collecting sensitive information from government agencies, including information about recent tariffs and trade disputes," security researcher Lior Rochberger said in a Monday analysis. Southeast Asia has increasingly become a focal point for cyber espionage due to its role in sensitive trade negotiations, military modernization, and strategic alignment in the U.S.–China power dynamic. Targeting government agencies in this region can provide valuable intelligence on foreign policy direction, infrastructure planni...

Cybersecurity researchers have charted the evolution of a widely used remote access trojan called AsyncRAT , which was first released on GitHub in January 2019 and has since served as the foundation for several other variants. "AsyncRAT has cemented its place as a cornerstone of modern malware and as a pervasive threat that has evolved into a sprawling network of forks and variants," ESET researcher Nikola Knežević said in a report shared with The Hacker News. "While its capabilities are not that impressive on their own, it is the open-source nature of AsyncRAT that has truly amplified its impact. Its plug-in-based architecture and ease of modification have sparked the proliferation of many forks, pushing the boundaries even further" While AsyncRAT's evolution highlights its technical adaptability, its real-world impact stems from how it's deployed in opportunistic phishing campaigns and bundled with loaders like GuLoader or SmokeLoader. These delivery metho...

Threat actors behind the Interlock ransomware group have unleashed a new PHP variant of its bespoke remote access trojan (RAT) as part of a widespread campaign using a variant of ClickFix called FileFix. "Since May 2025, activity related to the Interlock RAT has been observed in connection with the LandUpdate808 (aka KongTuke) web-inject threat clusters," The DFIR Report said in a technical analysis published today in collaboration with Proofpoint. "The campaign begins with compromised websites injected with a single-line script hidden in the page's HTML, often unbeknownst to site owners or visitors." The JavaScript code acts as a traffic distribution system (TDS), using IP filtering techniques to redirect users to fake CAPTCHA verification pages that leverage ClickFix to entice them into running a PowerShell script that leads to the deployment of NodeSnake (aka Interlock RAT). The use of NodeSnake by Interlock was previously documented by Quorum Cyber ...

Cybersecurity researchers have discovered a serious security issue that allows leaked Laravel APP_KEYs to be weaponized to gain remote code execution capabilities on hundreds of applications. "Laravel's APP_KEY, essential for encrypting sensitive data, is often leaked publicly (e.g., on GitHub)," GitGuardian said . "If attackers get access to this key, they can exploit a deserialization flaw to execute arbitrary code on the server – putting data and infrastructure at risk." The company, in collaboration with Synacktiv, said it was able to extract more than 260,000 APP_KEYs from GitHub from 2018 to May 30, 2025, identifying over 600 vulnerable Laravel applications in the process. GitGuardian said it observed over 10,000 unique APP_KEYs across GitHub, of which 400 APP_KEYs were validated as functional. APP_KEY is a random 32-byte encryption key that's generated during the installation of Laravel. Stored in the .env file of the application, it's used ...

A recently disclosed maximum-severity security flaw impacting the Wing FTP Server has come under active exploitation in the wild, according to Huntress. The vulnerability, tracked as CVE-2025-47812 (CVSS score: 10.0), is a case of improper handling of null ('\0') bytes in the server's web interface, which allows for remote code execution. It has been addressed in version 7.4.4. "The user and admin web interfaces mishandle '\0' bytes, ultimately allowing injection of arbitrary Lua code into user session files," according to an advisory for the flaw on CVE.org. "This can be used to execute arbitrary system commands with the privileges of the FTP service (root or SYSTEM by default)." What makes it even more concerning is that the flaw can be exploited via anonymous FTP accounts. A comprehensive breakdown of the vulnerability entered the public domain towards the end of June 2025, courtesy of RCE Security researcher Julien Ahrens. Cybersecuri...

Cybersecurity researchers have discovered a critical vulnerability in the open-source mcp-remote project that could result in the execution of arbitrary operating system (OS) commands. The vulnerability, tracked as CVE-2025-6514 , carries a CVSS score of 9.6 out of 10.0. "The vulnerability allows attackers to trigger arbitrary OS command execution on the machine running mcp-remote when it initiates a connection to an untrusted MCP server, posing a significant risk to users – a full system compromise," Or Peles, JFrog Vulnerability Research Team Leader, said . Mcp-remote is a tool that sprang forth following Anthropic's release of Model Context Protocol (MCP), an open-source framework that standardizes the way large language model (LLM) applications integrate and share data with external data sources and services. It acts as a local proxy, enabling MCP clients like Claude Desktop to communicate with remote MCP servers, as opposed to running them locally on the same...

Cybersecurity researchers have discovered new artifacts associated with an Apple macOS malware called ZuRu, which is known to propagate via trojanized versions of legitimate software. SentinelOne, in a new report shared with The Hacker News, said the malware has been observed masquerading as the cross‑platform SSH client and server‑management tool Termius in late May 2025. "ZuRu malware continues to prey on macOS users seeking legitimate business tools, adapting its loader and C2 techniques to backdoor its targets," researchers Phil Stokes and Dinesh Devadoss said . ZuRu was first documented in September 2021 by a user on Chinese question-and-answer website Zhihu as part of a malicious campaign that hijacked searches for iTerm2, a legitimate macOS Terminal app, to direct users to fake sites that tricked unsuspecting users into downloading the malware. Then in January 2024, Jamf Threat Labs said it discovered a piece of malware distributed via pirated macOS apps that s...

A Chinese national has been arrested in Milan, Italy, for his alleged links to a state-sponsored hacking group known as Silk Typhoon and for carrying out cyber attacks against American organizations and government agencies. The 33-year-old, Xu Zewei , has been charged with nine counts of wire fraud and conspiracy to cause damage to and obtain information by unauthorized access to protected computers, as well as committing aggravated identity theft. Details of the arrest were first reported by Italian media. Xu is alleged to have been involved in the U.S. computer intrusions between February 2020 and June 2021, including a mass attack spree that leveraged then-zero-day flaws in Microsoft Exchange Server, a cluster of activity the Windows maker designed as Hafnium . The suspect is also accused of participating in China's espionage efforts during the COVID-19 pandemic, attempting to gain access to vaccine research at various U.S. universities, including the University of Texas....
