A China-affiliated threat actor known as UNC6384 has been linked to a fresh set of attacks exploiting an unpatched Windows shortcut vulnerability to target European diplomatic and government entities between September and October 2025. The activity targeted diplomatic organizations in Hungary, Belgium, Italy, and the Netherlands, as well as government agencies in Serbia, Arctic Wolf said in a technical report published Thursday. "The attack chain begins with spear-phishing emails containing an embedded URL that is the first of several stages that lead to the delivery of malicious LNK files themed around European Commission meetings, NATO-related workshops, and multilateral diplomatic coordination events," the cybersecurity company said. The files are designed to exploit ZDI-CAN-25373 to trigger a multi-stage attack chain that culminates in the deployment of the PlugX malware using DLL side-loading. PlugX is a remote access trojan that's also referred to as Destroy...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and National Security Agency (NSA), along with international partners from Australia and Canada, have released guidance to harden on-premise Microsoft Exchange Server instances from potential exploitation. "By restricting administrative access, implementing multi-factor authentication, enforcing strict transport security configurations, and adopting zero trust (ZT) security model principles, organizations can significantly bolster their defenses against potential cyber attacks," CISA said . The agencies said malicious activity aimed at Microsoft Exchange Server continues to take place, with unprotected and misconfigured instances facing the brunt of the attacks. Organizations are advised to decommission end-of-life on-premises or hybrid Exchange servers after transitioning to Microsoft 365. Some of the best practices outlined are listed below - Maintain security updates and patching cadence Migrate end-o...

Eclipse Foundation, which maintains the open-source Open VSX project, said it has taken steps to revoke a small number of tokens that were leaked within Visual Studio Code (VS Code) extensions published in the marketplace. The action comes following a report from cloud security company Wiz earlier this month, which found several extensions from both Microsoft's VS Code Marketplace and Open VSX to have inadvertently exposed their access tokens within public repositories, potentially allowing bad actors to seize control and distribute malware, effectively poisoning the extension supply chain. "Upon investigation, we confirmed that a small number of tokens had been leaked and could potentially be abused to publish or modify extensions," Mikaël Barbero, head of security at the Eclipse Foundation, said in a statement. "These exposures were caused by developer mistakes, not a compromise of the Open VSX infrastructure." Open VSX said it has also introduced a toke...

The open-source command-and-control (C2) framework known as AdaptixC2 is being used by a growing number of threat actors, some of whom are related to Russian ransomware gangs. AdaptixC2 is an emerging extensible post-exploitation and adversarial emulation framework designed for penetration testing. While the server component is written in Golang, the GUI Client is written in C++ QT for cross-platform compatibility. It comes with a wide range of features, including fully encrypted communications, command execution, credential and screenshot managers, and a remote terminal, among others. An early iteration was publicly released by a GitHub user named " RalfHacker " ( @HackerRalf on X) in August 2024, who describes themselves as a penetration tester, red team operator, and "MalDev" (short for malware developer). In recent months, AdaptixC2 has been adopted by various hacking groups, including threat actors tied to the Fog and Akira ransomware operations, as ...

Security doesn't fail at the point of breach. It fails at the point of impact.  That line set the tone for this year's Picus Breach and Simulation (BAS) Summit , where researchers, practitioners, and CISOs all echoed the same theme: cyber defense is no longer about prediction. It's about proof. When a new exploit drops, scanners scour the internet in minutes. Once attackers gain a foothold, lateral movement often follows just as fast. If your controls haven't been tested against the exact techniques in play, you're not defending, you're hoping things don't go seriously pear-shaped. That's why pressure builds long before an incident report is written. The same hour an exploit hits Twitter, a boardroom wants answers. As one speaker put it, "You can't tell the board, 'I'll have an answer next week.' We have hours, not days." BAS has outgrown its compliance roots and become the daily voltage test of cybersecurity, the current you run through your stack to see what actuall...

Cybersecurity researchers are calling attention to a spike in automated attacks targeting PHP servers, IoT devices, and cloud gateways by various botnets such as Mirai , Gafgyt , and Mozi . "These automated campaigns exploit known CVE vulnerabilities and cloud misconfigurations to gain control over exposed systems and expand botnet networks," the Qualys Threat Research Unit (TRU) said in a report shared with The Hacker News. The cybersecurity company said PHP servers have emerged as the most prominent targets of these attacks owing to the widespread use of content management systems like WordPress and Craft CMS . This, in turn, creates a large attack surface as many PHP deployments can suffer from misconfigurations, outdated plugins and themes, and insecure file storage. Some of the prominent weaknesses in PHP frameworks that have been exploited by threat actors are listed below - CVE-2017-9841 - A Remote code execution vulnerability in PHPUnit CVE-2021-3129 - A Re...

Organizations in Ukraine have been targeted by threat actors of Russian origin with an aim to siphon sensitive data and maintain persistent access to compromised networks. The activity, according to a new report from the Symantec and Carbon Black Threat Hunter Team, targeted a large business services organization for two months and a local government entity in the country for a week. The attacks mainly leveraged living-off-the-land (LotL) tactics and dual-use tools, coupled with minimal malware, to reduce digital footprints and stay undetected for extended periods of time. "The attackers gained access to the business services organization by deploying web shells on public-facing servers, most likely by exploiting one or more unpatched vulnerabilities," the Broadcom-owned cybersecurity teams said in a report shared with The Hacker News. One of the web shells used in the attack was Localolive, which was previously flagged by Microsoft as put to use by a sub-group of the ...

Cybersecurity researchers have discovered a set of 10 malicious npm packages that are designed to deliver an information stealer targeting Windows, Linux, and macOS systems. "The malware uses four layers of obfuscation to hide its payload, displays a fake CAPTCHA to appear legitimate, fingerprints victims by IP address, and downloads a 24MB PyInstaller-packaged information stealer that harvests credentials from system keyrings, browsers, and authentication services across Windows, Linux, and macOS," Socket security researcher Kush Pandya said . The npm packages were uploaded to the registry on July 4, 2025, and accumulated over 9,900 downloads collectively - deezcord.js dezcord.js dizcordjs etherdjs ethesjs ethetsjs nodemonjs react-router-dom.js typescriptjs zustand.js The multi-stage credential theft operation manifested in the form of various typosquatted packages impersonating popular npm libraries such as TypeScript, discord.js, ethers.js, nodemon, react...

Threat actors are actively exploiting multiple security flaws impacting Dassault Systèmes DELMIA Apriso and XWiki, according to alerts issued by the U.S. Cybersecurity and Infrastructure Security Agency ( CISA ) and VulnCheck . The vulnerabilities are listed below - CVE-2025-6204 (CVSS score: 8.0) - A code injection vulnerability in Dassault Systèmes DELMIA Apriso that could allow an attacker to execute arbitrary code. CVE-2025-6205 (CVSS score: 9.1) - A missing authorization vulnerability in Dassault Systèmes DELMIA Apriso that could allow an attacker to gain privileged access to the application. CVE-2025-24893 (CVSS score: 9.8) - An improper neutralization of input in a dynamic evaluation call (aka eval injection ) in XWiki that could allow any guest user to perform arbitrary remote code execution through a request to the "/bin/get/Main/SolrSearch" endpoint. Both CVE-2025-6204 and CVE-2025-6205 affect DELMIA Apriso versions from Release 2020 through Release 202...

Cybersecurity researchers have disclosed details of a new Android banking trojan called Herodotus that has been observed in active campaigns targeting Italy and Brazil to conduct device takeover ( DTO ) attacks. "Herodotus is designed to perform device takeover while making first attempts to mimic human behaviour and bypass behaviour biometrics detection," ThreatFabric said in a report shared with The Hacker News. The Dutch security company said the Trojan was first advertised in underground forums on September 7, 2025, as part of the malware-as-a-service (MaaS) model, touting its ability to run on devices running Android version 9 to 16. It's assessed that while the malware is not a direct evolution of another banking malware known as Brokewell , it certainly appears to have taken certain parts of it to put together the new strain. This includes similarities in the obfuscation technique used, as well as direct mentions of Brokewell in Herodotus (e.g., "BRKWL_...

In cybersecurity, speed isn't just a win — it's a multiplier. The faster you learn about emerging threats, the faster you adapt your defenses, the less damage you suffer, and the more confidently your business keeps scaling. Early threat detection isn't about preventing a breach someday: it's about protecting the revenue you're supposed to earn every day. Companies that treat cybersecurity as a reactive cost center usually find themselves patching holes, paying ransoms, and dealing with downtime. Companies that invest in proactive visibility, threat intelligence, and early detection mechanisms stay in the game longer. With trust, uptime, and innovation intact. Let's break down why this strategy directly connects to long-term business success: 1. Early detection drastically lowers the cost of incidents A breach caught at initial access might cost just internal response hours. Caught at data exfiltration — multiply the cost by 10, and a breach caught after regulatory violations kick...

A European embassy located in the Indian capital of New Delhi, as well as multiple organizations in Sri Lanka, Pakistan, and Bangladesh, have emerged as the target of a new campaign orchestrated by a threat actor known as SideWinder in September 2025. The activity "reveals a notable evolution in SideWinder's TTPs, particularly the adoption of a novel PDF and ClickOnce -based infection chain, in addition to their previously documented Microsoft Word exploit vectors," Trellix researchers Ernesto Fernández Provecho and Pham Duy Phuc said in a report published last week. The attacks, which involved sending spear-phishing emails in four waves from March through September 2025, are designed to drop malware families such as ModuleInstaller and StealerBot to gather sensitive information from compromised hosts. While ModuleInstaller serves as a downloader for next-stage payloads, including StealerBot, the latter is a .NET implant that can launch a reverse shell, deliver addi...

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here's how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild. The vulnerability in question is CVE-2025-59287 (CVSS score: 9.8), a remote code execution flaw in WSUS that was originally fixed by the tech giant as part of its Patch Tuesday update published last week. According to Eye Security and Huntress, the security flaw is being weaponized to drop a .N...

The ransomware group known as Qilin (aka Agenda, Gold Feather, and Water Galura) has claimed more than 40 victims every month since the start of 2025, barring January, with the number of postings on its data leak site touching a high of 100 cases in June. The development comes as the ransomware-as-a-service (RaaS) operation has emerged as one of the most active ransomware groups , accounting for 84 victims each in the months of August and September 2025. The Russian-speaking threat group emerged around July 2022. According to data compiled by Cisco Talos, the U.S., Canada, the U.K., France, and Germany are some of the countries most impacted by Qilin. The attacks have primarily singled out manufacturing (23%), professional and scientific services (18%), and wholesale trade (10%) sectors. Attacks mounted by Qilin affiliates have likely leveraged leaked administrative credentials on the dark web for initial access using a VPN interface, followed by performing RDP connections to th...

The threat actors behind a large-scale, ongoing smishing campaign have been attributed to more than 194,000 malicious domains since January 1, 2024, targeting a broad range of services across the world, according to new findings from Palo Alto Networks Unit 42. "Although these domains are registered through a Hong Kong-based registrar and use Chinese nameservers, the attack infrastructure is primarily hosted on popular U.S. cloud services," security researchers Reethika Ramesh, Zhanhao Chen, Daiping Liu, Chi-Wei Liu, Shehroze Farooqi, and Moe Ghasemisharif said . The activity has been attributed to a China-linked group known as the Smishing Triad , which is known to flood mobile devices with fraudulent toll violation and package misdelivery notices to trick users into taking immediate action and providing sensitive information. These campaigns have proven to be lucrative, allowing the threat actors to make more than $1 billion over the last three years, according to a re...

Does your organization suffer from a cybersecurity perception gap? Findings from the  Bitdefender 2025 Cybersecurity Assessment suggest the answer is probably "yes" — and many leaders may not even realize it. This disconnect matters. Small differences in perception today can evolve into major blind spots tomorrow. After all, perception influences what organizations prioritize, where they allocate resources, and how they respond in critical moments. Confidence at the Top, Caution on the Ground Bitdefender's latest assessment surveyed  1,200 cybersecurity and IT professionals , and at first glance, the results suggest optimism. An impressive  93% say they are "somewhat" or "very confident" in their ability to manage cyber risk as the attack surface expands. But dig deeper, and the optimism begins to split. Nearly half ( 45% ) of C-level respondents — including CISOs and CIOs — describe themselves as "very confident" in their organization's readiness. Yet among mid-l...

A malicious network of YouTube accounts has been observed publishing and promoting videos that lead to malware downloads, essentially abusing the popularity and trust associated with the video hosting platform for propagating malicious payloads. Active since 2021, the network has published more than 3,000 malicious videos to date, with the volume of such videos tripling since the start of the year. It has been codenamed the YouTube Ghost Network by Check Point. Google has since stepped in to remove a majority of these videos. The campaign leverages hacked accounts and replaces their content with "malicious" videos that are centred around pirated software and Roblox game cheats to infect unsuspecting users searching for them with stealer malware. Some of these videos have racked up hundreds of thousands of views, ranging from 147,000 to 293,000. "This operation took advantage of trust signals, including views, likes, and comments, to make malicious content seem safe,...

Threat actors with ties to North Korea have been attributed to a new wave of attacks targeting European companies active in the defense industry as part of a long-running campaign known as Operation Dream Job . "Some of these [companies] are heavily involved in the unmanned aerial vehicle (UAV) sector, suggesting that the operation may be linked to North Korea's current efforts to scale up its drone program," ESET security researchers Peter Kálnai and Alexis Rapin said in a report shared with The Hacker News. It's assessed that the end goal of the campaign is to plunder proprietary information and manufacturing know-how using malware families such as ScoringMathTea and MISTPEN. The Slovak cybersecurity company said it observed the campaign starting in late March 2025. Some of the targeted entities include a metal engineering company in Southeastern Europe, a manufacturer of aircraft components in Central Europe, and a defense company in Central Europe. While Sc...
