Lunex Stealer Abuses AMD Driver to Disable Security Monitoring and Steal Browser Credentials

Sep 26, 2026Malware / Endpoint Security

The Psychedelic Stealer malware distributed via compromised Ukrainian websites using ClickFix-style Cloudflare verification checks is part of a wider malware-as-a-service (MaaS) platform called Lunex . The new findings come from Ontinue, which described the activity as a four-stage attack chain aimed at targeting Ukrainian-speaking users. "The attack chain begins with a fake CAPTCHA page and culminates in the deployment of a fully-featured C2 agent," Ontinue threat researcher Rhys Downing said in a technical report. "The stealer extracts credentials and data from seven Chromium-based browsers, exfiltrates cryptocurrency wallets, and establishes persistent remote filesystem access through a PowerShell-based Native Messaging Host installed within the victim's browser." The infection makes use of bogus MSI installers delivered via ClickFix to trigger a series of actions, including delivering a loader dubbed LunexLoader that's designed to bypass User Ac...

Attackers Bypass WAFs to Exploit Oracle PeopleSoft Flaw and Deploy Web Shells

Sep 26, 2026Vulnerability / Web Security

Google is warning of renewed mass exploitation of a known security vulnerability in Oracle PeopleSoft as part of a campaign targeting multiple sectors globally. The ShinyHunters-linked activity involves the weaponization of CVE-2026-35273 (CVSS score: 9.8), a critical security flaw that could result in unauthenticated remote code execution. The vulnerability was first exploited as a zero-day in attacks against academic institutions to conduct reconnaissance, deploy remote access software like MeshCentral agent for persistence, move laterally over SSH, run a shell script to connect via SSH to other internal PeopleSoft machines using known username/password combinations, and steal data. At that time, Google-owned Mandiant said it initiated notifications to over 100 global organizations whose IP addresses matched vulnerable endpoints, most of them located in the U.S. "This new wave of activity stems from UNC6240 modifying its exploit to bypass web application firewall (WAF...

Zero Trust for AI Agents Starts With Fixing Zero Visibility

Sep 26, 2026Artificial Intelligence / Cloud Security

The way we talk about AI agents is shifting, and the way we implement them requires an even more fundamental shift. While earlier discourse focused on how quickly organizations could stand up agents and how much productivity they could promise, a string of recent incidents, including a widely discussed intrusion at Hugging Face during an evaluation of OpenAI agents, has spurred organizations to examine whether speed has outpaced the ability to secure what gets deployed . Security teams are increasingly asking what an agent can reach once it's running, and whether anyone would notice before it mattered. However tempting it may be to jump directly into enforcement controls and detections, you need to look before you leap. Research from Veeam reveals that 70% of organizations admit that AI workflows are already in contact with sensitive corporate data without full oversight in place, and 67% report that IT cannot fully track the autonomous workflows that employees are building.

Elementor CSRF Flaw Lets Attackers Take Over Sites After Admin Clicks Crafted Link

Sep 26, 2026Vulnerability / Web Security

Details have emerged about a high-severity security flaw in the Elementor Website Builder WordPress plugin that could be exploited by an unauthenticated attacker to create rogue administrator accounts and take control of a site. The cross-site request forgery (CSRF) vulnerability, which has yet to be assigned a CVE identifier, carries a CVSS score of 8.8 out of 10.0. It only affects versions 4.3.0 and 4.3.1 of the plugin, which is active on over 10 million WordPress sites. Statistics from WordPress.org show that the two impacted versions alone have been installed on more than 2 million sites. "One link, opened by a logged-in WordPress user, makes that user carry out any REST API action their account is permitted to perform," Patchstack said . "On a stock installation, an administrator clicking the link creates a second administrator account for the attacker." The WordPress security company said the attack does not hinge on any prerequisite, such as JavaScrip...

SharePoint RCE and MikroTik RouterOS Flaws Actively Exploited in the Wild

Sep 26, 2026Vulnerability / Network Security

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two security flaws impacting Microsoft SharePoint and Mikrotik RouterOS to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities in question are as follows - CVE-2026-65660 (CVSS score: 8.8) - A code injection vulnerability in Microsoft Office SharePoint that allows an authorized attacker to execute code over a network. CVE-2026-67279 (CVSS score: 6.9) - An improper enforcement of behavioral workflow vulnerability in  Mikrotik RouterOS that could allow an unauthenticated client to open a session channel and send an exec request. As reported by The Hacker News earlier this week, CVE-2026-65660 was originally described by Microsoft as a spoofing vulnerability impacting SharePoint Server. The tech giant has since updated the advisory to state that it could be abused to obtain remote code execution. "As of 9/25/2026, Microsoft ...

Kiteworks Urges Customers to Shut Down Systems for 9 Hours Over Possible Cyber Attack

Sep 26, 2026Threat Intelligence / Vulnerability

Kiteworks (formerly Accellion) is urging customers to shut down their systems as a precautionary measure for nine hours over the weekend after it received threat intelligence about an imminent cyber attack. "Kiteworks received credible threat intelligence from federal intelligence authorities indicating that a threat actor may attempt to target some Kiteworks systems," said Frank Balonis, Chief Information Security Officer (CISO) at Kiteworks. "Out of an abundance of caution, we notified customers directly and recommended a precautionary shutdown window while we continue to work through the matter with federal intelligence authorities." The company said it has not found any evidence that its customers' systems have been compromised, emphasizing the advisory is preventative rather than a response to a confirmed hack. The development was first reported by German news publication Heise. Kiteworks did not disclose which law enforcement agency alerted the ...

Compromised GitHub Actions Came Back Online and Resumed Executing Mini Shai-Hulud Malware

Sep 25, 2026Malware / Supply Chain Attack

Two actions-cool GitHub Actions have been disabled for a second time after the repositories became accessible last week, months after they were compromised during the May 2026 Mini Shai-Hulud campaign . The affected GitHub Actions are listed below - actions-cool/issues-helper actions-cool/maintain-one-comment Visiting either of the repositories now shows the message: "Access to this repository has been disabled by GitHub Staff due to a violation of GitHub's terms of service. If you are the owner of the repository, you may reach out to GitHub Support for more information." "On September 16, 2026, both repositories became accessible again," Socket researcher Karlo Zanki said . "Their release tags were not cleaned up first. They still point to the malicious content introduced on May 18, so any workflow that references either action by a version tag resumed downloading and executing the payload on its next run." The two GitHub Actions work...

PamStealer macOS Malware Adds Live C2 Payload Decryption and Multi-Layer Persistence

Sep 25, 2026Malware / Social Engineering

Cybersecurity researchers have flagged a new version of PamStealer that ensures that the main payload can only be recovered using a server-side decryption chain. The latest artifacts, per Jamf Threat Labs, continue to rely on the same JavaScript for Automation (JXA) dropper mechanism, but modify the lure and the delivery method. "Where earlier variants embedded their payload key material directly in the JXA source, it now fetches a purpose-built decryption utility and completes a key exchange with the server before the payload can be unwrapped," security researcher Thijs Xhaflaire said in an analysis. "Without the server's cooperation, the payload cannot be recovered statically." A second major change is the choice of the decoy itself. While previous versions observed in July and August 2026 were observed using fake websites masquerading as Maccy, Scoppr, and Nancy Clipboard, victims are now lured through a bogus website ("wavel[.]app") advert...

The SOC Doesn't Need to Start Over with Every Alert

Sep 25, 2026Artificial Intelligence / Security Operations

Security leaders keep debating whether AI will produce an entirely new class of cyberattack. The nearer change is quieter and already visible: AI has made a failed attack cheap to retry. The routine version looks like this. An attacker lands on a low-privilege cloud account, and the first try at privilege escalation goes nowhere. That dead end used to cost hours of documentation reading, permission checks, and script debugging, and plenty of operators simply got stuck. With a model in the loop, the error gets explained, the script gets fixed, and a fresh enumeration path is under test within minutes. No step in that sequence is a new capability. Together they strip time, skill, and cost out of the unglamorous middle of an intrusion, the research and troubleshooting that sit between intent and outcome. What the threat reporting shows The public record traces the arc. In early 2025, Google's Threat Intelligence Group found state-backed actors treating generative AI as a prod...

Bitget Says Suspected North Korean Hackers Stole $351.6M After Backend Compromise

Sep 25, 2026Cryptocurrency / Cybercrime

Cryptocurrency exchange Bitget said suspected North Korean threat actors have stolen $351.6 million from its hot and warm wallets.  "At 18:31 UTC on September 24, 2026, Bitget's security systems identified unauthorized transfers involving a limited number of hot wallets," BitGet said in a post shared on X. "Bitget's cold wallets and the overwhelming majority of platform assets remain secure and unaffected." The company emphasized that customer account balances remain accurate, and deposits and trading continue to operate normally. However, withdrawals have been temporarily suspended out of an abundance of caution while a "comprehensive security review" is underway. Bitget did not disclose any details on how the attack took place, but said it has enlisted the help of Google-owned Mandiant and SlowMist for a third-party investigation. "Bitget Wallet operates as a self-custodial wallet on a completely separate and independent infrastruc...

Roundcube Pre-Auth SQL Injection Flaw Actively Exploited in the Wild

Sep 25, 2026Vulnerability / Email Security

The Canadian Centre for Cyber Security has warned that a now-patched Roundcube Webmail vulnerability is being actively exploited in the wild. The vulnerability in question is CVE-2026-48842 (CVSS score: 8.1), a pre-authentication SQL injection in the virtuser_query plugin of Roundcube Webmail versions 1.6.x before 1.6.16 and 1.7.x before 1.7.1. The issue stems from a preg_replace() backslash escape bypass that allows attackers to inject arbitrary SQL statements without authentication. "Unauthenticated attackers can inject SQL into Roundcube's database backend through the virtuser_query plugin, potentially exposing mail account credentials and stored messages," SentinelOne said . Patches for the vulnerability were released by Roundcube in May 2026 as part of 1.6.16 and 1.7.1. In an update shared this week, the Cyber Centre said the security flaw is being actively exploited in the wild, citing open-source reporting. No additional details of the exploitation ac...

Cloudflare Fixes Flaw That Let One Container Read Another Customer's Leftover Disk Data

Sep 25, 2026Cloud Security / Vulnerability

A flaw in Cloudflare Containers let a paying customer read data that other customers' containers had left behind on the same server, Cloudflare and the researchers who found it said on Thursday. The data came from disk space that earlier containers had used and given up, not from any live workload, and an attacker could not choose whose data they got,  according to Cloudflare . The company has fixed the flaw across its service and says customers need to do nothing. Cloudflare Containers runs customers' programs inside containers on servers shared by many accounts, and Cloudflare, not the customer, picks the server. Cloudflare Sandboxes, which runs on Containers and is sold as a safe place to run untrusted code, including code written by AI agents, was affected too. The flaw was reported on September 4 by Oren Yomtov of the security firm Accomplish , through Cloudflare's bug bounty program. The problem was in how the shared disks were set up. Each container gets a ...

Unpatched OnePlus Flaws Let Installed Android Apps Gain Root Without Permissions

Sep 24, 2026Vulnerability / Mobile Security

A OnePlus 15 running the latest OxygenOS can be rooted by a malicious app the owner installs, one that asks for no special permissions. A researcher, Rasmus Moorats,  chained two flaws in OnePlus's own software  to gain root access, the highest level of control over an Android phone. OnePlus told him the same flaws affect many more of its own devices and those of OPPO, though it has not said which. OnePlus confirmed both flaws in May. In the same reply, the company told Moorats that it alone decides when to make a flaw public and warned that publishing without its permission could result in legal liability. He published on September 24 anyway, when OnePlus had released no fix. OnePlus set out its position in the reply,  which Moorats published in full . It said a fix was scheduled, but claimed "the exclusive final right of vulnerability disclosure," and told him that even after a fix ships, researchers may not publish full technical details on their own. The comp...

Placeholder third-party[.]com Referenced Across 1,700+ Repositories Now Serves Malicious Content

Sep 24, 2026Phishing / Malware

The "third-party[.]com" domain, commonly used as a documentation placeholder, has been observed serving a ClickFix lure to Windows browsers while displaying a harmless decoy to other users. "third-party[.]com has been a generic documentation placeholder for years, the same role example.com plays," Manifold Security's Head of Research, Ax Sharma, said . "Unlike 'example[.]com,' third-party[.]com is not IANA-reserved . Anyone could register it, and someone did. Every doc, test, and skill that hard-coded it now points readers at attacker infrastructure." As of writing, the domain has been marked as malicious and unsafe on both VirusTotal and Google's Safe Browsing list . ClickFix is a social engineering attack technique in which either malicious or legitimate-but-compromised websites display error messages, browser alerts, or CAPTCHA verification prompts, tricking users into copying and executing hidden commands via the Windows Run d...
