Microsoft has disclosed details of a Windows-based cryptocurrency clipper campaign that has targeted users since February 2026. "The clipper in this campaign relies on Windows Script Host and ActiveX-driven logic to launch a bundled Tor proxy and poll a hidden-service C2 [command-and-control] server," the Microsoft Defender Security Research Team said in an analysis published Tuesday. "It carries out high-frequency clipboard theft, screenshot exfiltration, and wallet-address substitution." "The execution of this clipper is notable because it does not depend on a traditional installer or exposed IP-based C2 infrastructure. Instead, it deploys a portable Tor client, routes traffic through a local SOCKS5 proxy, and blends data theft with remote code execution, turning a financially motivated stealer into a lightweight backdoor." Clipper malware refers to a type of malicious software that silently monitors a user's clipboard and intercepts sensiti...

Cybersecurity researchers have charted the evolution of INC from an nascent ransomware-as-a-service (RaaS) operation to one of the most prolific cybercrime groups in 2026, claiming no less than 830 victims since August 2023. "The disruption of LockBit and the shutdown of BlackCat created opportunities for INC to expand as affiliates migrated to alternative ransomware operations," Acronis researcher Darrel Virtusio said . "United States organizations account for more than 65% of listed victims, with legal services, manufacturing, construction, technology and health care among the most targeted sectors." INC's Windows and Linux/ESXi encryptors have also been rewritten in Rust to facilitate easier cross-platform development and better resist reverse engineering efforts. Attacks deploying the ransomware are characterized by the use of an updated credential dumper capable of targeting newer Veeam backup deployments that use the salted DPAPI credential encryp...

An independent PCI assessor tested Reflectiz against the new PCI DSS rules. Here is the verdict: See the full QSA assessment here → When a customer types their card number into your checkout, their browser is running far more than your code. Analytics tags, a tag manager, a support widget, a payment iframe: a modern checkout loads dozens of third-party scripts, and any one of them can be turned into a skimmer. This is how Magecart works. Sansec has counted more than 100,000 sites hit by web skimming and supply-chain attacks. The 2018 British Airways breach alone exposed 380,000 transactions and a fine that started at £183 million. The dangerous part: the malicious code usually arrives through a script you already approved. Attackers compromise a third-party vendor, and the payload rides in on a script you have run for months. Nothing looks new. What changed is the script's behavior, not its presence on the page. PCI DSS v4.0.1 closes that gap with two requirements, now...

Threat actors associated with the DragonForce ransomware have been observed using a custom Go-based remote access trojan (RAT) called Backdoor.Turn to conceal command-and-control (C2) traffic inside Microsoft Teams relay infrastructure. According to findings from Broadcom-owned Symantec and Carbon Black, the backdoor was deployed against a major U.S. services firm. The name of the company was not disclosed. "Backdoor.Turn obtains an anonymous Teams visitor token from Microsoft’s Skype-backed identity services, uses a legitimate Microsoft TURN relay to set up the connection, and then runs a QUIC session to the attacker’s real command-and-control (C2) server," the Threat Hunter Team said in a report shared with The Hacker News. "To network defenders, the only traffic they could see was outbound connections to legitimate Microsoft Teams servers. The attackers were on the victim network for between one and two months."

An unknown threat actor has been observed leveraging paid or promoted posts on legitimate news websites to drum up buzz for their warez, according to new findings from Check Point Research. The threat actor also has at their disposal a dedicated WordPress phishing page that acts as the central hub, alongside GitHub and SourceForge projects promoted by fake accounts, a YouTube channel, and a cluster of accounts that engage in coordinated activity on VirusTotal with the intent to misclassify malicious files as safe. "To push a malicious 'tool,' a single threat actor borrowed the same playbook legitimate brands use to build buzz: inflated download counts, coordinated five-star reviews, influencer-style tutorial videos, and promotion on platforms people instinctively trust," Check Point said in a report shared with The Hacker News. "The result is a fake reputation economy spanning every platform a curious victim might check before they click 'download.'...

Microsoft has formally disclosed that it's working to release a patch to address a Defender zero-day codenamed RoguePlanet . The vulnerability has now been assigned the CVE identifier CVE-2026-50656 (CVSS score: 7.8), with the tech giant describing it as a privilege escalation flaw. "Microsoft is aware of an elevation of privilege in the Microsoft Malware Protection Engine in Microsoft Defender, publicly referred to as 'RoguePlanet,'" the company said. "We are working to provide a high-quality security update that addresses this vulnerability."  The development comes nearly a week after a security researcher named Chaotic Eclipse (aka Nightmare-Eclipse) released RoguePlanet, calling the exploit a case of a race condition that grants attackers a shell with SYSTEM-level privileges. "The exploit is a race condition, so it's a hit or miss," the researcher noted. "I have managed to get a 100% success rate on some machines while it...

A French-speaking attacker broke into a small French automotive business, planted a keylogger, and stole banking and email credentials. Ordinary stuff, until one move near the end. Before his command-and-control server went dark, he installed OpenSSH and Tailscale on a victim's machine, building a way back in that did not run through the C2 at all. When the Havoc server went offline the next day, his access did not. Eighteen days later, the C2 came back, his agents reconnected on their own, and he carried on. Cato Networks captured the whole operation command by command, 339 of them over 33 days, after the operator left his SSH keys and a step-by-step playbook in an open storage bucket. The write-up, published Tuesday by Cato CTRL researcher Vitaly Simonovich, is a rare view of an intrusion from the operator's keyboard rather than the forensic leftovers. Researchers' lesson is blunt: pulling a C2 server offline is not remediation if the attacker has already built a...

For security teams, the findings never stop, but confidence in knowing which ones matter is becoming harder to maintain. The problem is no longer visibility. It's validation. Security teams must decide which findings warrant action while operating under constant pressure and incomplete information. Increasingly, the challenge is not discovering potential risks. It is determining which risks deserve attention first. Visibility Got Us Here. Validation Moves Us Forward. The security industry has spent the better part of a decade improving visibility. Vulnerability scanners, cloud security posture tools, endpoint detection, attack surface platforms, code analysis, and threat intelligence feeds all contribute to a more complete understanding of the attack surface. The investment has been enormous, and it has largely worked. Modern enterprises can see their environments in ways that would have seemed remarkable ten years ago. Yet improved visibility has not automatically transla...

Cybersecurity researchers have flagged a "coordinated malware campaign" on the JetBrains Marketplace that has published no less than 15 malicious plugins capable of exfiltrating artificial intelligence (AI) provider keys. "Every plugin poses as an AI coding assistant built on DeepSeek and other large language models, offering chat, commit messages, code review, bug finding, and unit tests," Aikido Security researcher Ilyas Makari said . "They function exactly as advertised. However, the AI provider API key you enter gets exfiltrated to a server controlled by the attacker." The activity is said to have been ongoing since the end of October 2025, with new plugins released as recently as June 10, 2026. Two of the plugins, CodeGPT AI Assistant and DeepSeek AI Assist, have more than 25,000 downloads each, although it's not clear if the counts are authentic or if they have been inflated to fake their popularity. The complete list of plugins is below -...

Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk. With time-to-exploit now down to a single day, the question isn't just how fast you can patch. It's why the service was exposed in the first place. The team at Intruder analyzed 3,000 attack surfaces to find out how much of a typical organization's attack surface consists of services that have no reason to be there. We grouped what we found into four categories — HTTP panels, risky ports and services, databases, and publicly accessible files and information. The full findings, including breakdowns by company size and industry, are in our 2026 Attack Surface Management Index . How widespread is the problem? ...

As many as 145 npm packages associated with the Mastra namespace ("@mastra/*"), a popular open-source JavaScript and TypeScript framework for building artificial intelligence (AI) applications, have been compromised as part of a software supply chain attack codenamed easy-day-js , per findings from Endor Labs , JFrog , OX Security , SafeDep , Socket , StepSecurity , and Synk . "A single npm account (ehindero) mass-published more than 140 malicious packages across the Mastra scope within a short window on 2026-06-17," Socket said. The infected packages themselves do not include malicious code. Instead, it's introduced by means of a third-party library named "easy-day-js" that has been added to each package's dependency list in what has been described as an automated publishing campaign spanning 88 minutes. In its analysis, SafeDep described "easy-day-js" as a clone of the "dayjs" date library that downloads and runs a ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a maximum-severity security flaw impacting Widget Factory Joomla Content Editor (JCE) to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-48907 (CVSS score: 10.0), is a case of improper access control that could facilitate arbitrary code execution. "Widget Factory Joomla Content Editor contains an improper access control vulnerability which could allow for upload and execution of PHP code via the creation of new editor profiles for unauthenticated users," CISA said . According to a description of the vulnerability published on CVE.org, the issue resides in the JCE editor extension for Joomla, allowing a bad actor to create new editor profiles for unauthenticated users, effectively paving the way for PHP code upload and execution. The issue impacts JCE versions from 1.0.0 through 2.9.99.4. It has been pa...
