Hackers Hide Linux Backdoor in Control Web Panel Server to Execute Commands Without Logs
A backdoor has been found hiding in the web server that runs Control Web Panel (CWP), a free panel for managing Linux hosting servers, researchers at QiAnXin's XLab said this week. The backdoored web server executes commands that attackers send via web requests, and those requests never appear in its access logs. Installing it takes root access, so the attackers must already co
Researchers Bypass ChatGPT Lockdown Mode to Exfiltrate Chats Without User Interaction
Cybersecurity researchers have disclosed details of a now-patched vulnerability that could be exploited to bypass Lockdown Mode protections in OpenAI ChatGPT. Lockdown Mode was introduced by the artificial intelligence (AI) company in June 2026 as an optional setting to minimize data exfiltration risks arising from prompt injections. "The flaw could enable silent chat data thef
OpenSSH Issues Emergency Fix for Flaw Letting Long Passwords Bypass SSH Auth on Alpine Linux
Attackers can log in to accounts that have no password, such as SSH key-only accounts, on some Alpine Linux servers running the standard openssh-server package. They need network access to the server, an account name, and a password between 257 and 1,024 bytes long. OpenSSH, which rates the flaw critical, released version 10.6p2 today to block it. Alpine has published fixed pac
ThreatsDay: Apache OFBiz RCE, DreamHost Breach, DeFi Site Hijacks + 17 More Stories
How much damage can someone do without breaking much? Quite a lot, it seems. A stolen login can open doors across several systems. A trusted setting can be used to lock people out. Even a simple file copy can reach places it shouldn't. And while new tools are helping find security holes faster, some important systems are still taking months, sometimes over a year, to get patche
Is Your Exposure Management Platform Leaving You Exposed? Five Tests to Find Out
A critical finding can move through several security tools and still leave the organization exposed. The vulnerability has a severity score, and a ticket has reached the queue. Progress then depends on information the finding may lack: who owns the system, whether attackers can reach it, what protection exists, and how a change could affect the business. Each missing detail cre
5 Active Cyber Threats That Put US Enterprises at Risk in October 2026
October 2026 brought another wave of cyber threats targeting US businesses, with attackers exploiting trusted platforms, legitimate authentication processes, and everyday business workflows. For enterprises, these campaigns raise the stakes beyond individual security incidents, increasing the risk of financial losses, data breaches, and costly operational disruption. Below, we
CERT-In Flags AI-Driven Attacks as Backdoored ARTEX Exposes 62 Consoles to Root Access
The Indian Computer Emergency Response Team (CERT-In) has disclosed that an artificial intelligence (AI)-assisted threat actor it tracks as Crafty Falcon is targeting organizations in the Banking, Financial Services, and Insurance (BFSI) sectors in the country. Describing the threat as active and ongoing, the activity involves the use of publicly-available AI-driven offensive s
Apple to Start Scanning Publicly Shared iCloud Photos and Files for Harmful Content
Apple has revealed that it plans to start checking public iCloud links for harmful content starting with iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3. The change specifically applies to scenarios where users share iCloud content, such as photos in iCloud Photos or files in iCloud Drive, by sharing a link and making it accessible to "Anyone with the link." When users cho
Zyxel GS1900 Patch Fails to Block Zero-Day Exploit Allowing Root Command Execution
Zyxel GS1900 network switches that received the vendor's earlier fix for an actively exploited flaw are still open to the exploit attackers used, researchers at Binarly found. The exploit lets anyone who can reach a switch's web management interface run commands on it without logging in. Zyxel has released new firmware for 10 GS1900 models that closes the hole. The earlier fix
Hackers Exploit Patched Apple Flaw to Deliver Info-Stealing Malware, CISA Says
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a medium-severity security flaw impacting multiple Apple operating systems to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation. The vulnerability in question is CVE-2024-27834 (CVSS score: 5.5), a case of improper authentication that could allow an atta
OpenAI AI Pipeline Generates 948 Linux Root Escalation Exploits in 30-Hour Run
OpenAI on Wednesday detailed a pipeline that employed an upcoming cyber-focused artificial intelligence (AI) model to validate and patch 948 local privilege escalation vulnerabilities in Linux for $1.2 million in API costs. "Our prototype identified and analyzed 2,308 candidate Linux kernel findings, dynamically reproduced 1,724 vulnerabilities, and produced 948 local privilege
SonicWall Won't Patch EoL GMS Flaws That Could Expose Files, Alter Database Records
SonicWall has warned of two vulnerabilities impacting end-of-life Global Management System (GMS) systems that it said will not be patched. Details of the security flaws, which affect SonicWall GMS 9.5.2 and earlier versions, are below - CVE-2026-109593 (CVSS score: 9.1) - An unauthenticated file read vulnerability that could allow an attacker with network access to read interna
Debian and Ubuntu APT Flaw Lets MitM Attackers Swap Verified Packages and Run Code as Root
A flaw in APT, the package manager for Debian and Ubuntu, allows an attacker who can modify package downloads to swap a checked package for their own. The attacker's code then runs as root, according to advisories that Debian, Ubuntu, and APT's developers published on November 4. The attack needs APT to retry failed downloads, which it does by default from Debian 12 and
APT29-Linked Hackers Hijack Web Analytics Script to Deliver iOS and Android Exploits
The Russia-linked threat actor known as APT29 is said to be behind a large-scale watering hole campaign targeting iOS and Android users through compromised websites, fake domains, and a supply chain attack involving a Ukrainian web analytics service called Plerdy SEO Tracker. "The injected JavaScript code collects browser and device attributes," Sekoia researchers Amaury-Jacque
Xen Hypervisor Flaws Let One Malicious VM Read and Write Any Other VM's Memory
Two flaws in the Xen hypervisor allow a malicious guest virtual machine (VM) to read and write the memory of other VMs on the same host, including dom0. Dom0 is the VM that, by default, has full permissions and manages the others. Patches are out, and there is no known mitigation, the Xen Project said in an advisory on November 3. All Xen versions from 4.6 onward are vulnerable
Critical Rails Flaw Lets Attackers Write Server Files via Crafted ImageMagick Uploads
A critical flaw in Ruby on Rails could allow an unauthenticated attacker to write arbitrary files on an app's server by uploading a crafted file if the app processes uploads using ImageMagick. The Rails project disclosed the flaw in an advisory and fixed it in versions 8.1.4.1 and 8.0.5.2. The flaw is in Active Storage, the part of Rails that handles file uploads. Some apps sto
Google Issues Patches for Critical Android Flaw That Could Allow RCE Without User Interaction
A critical Android flaw could allow an attacker to run code on a phone without any user action remotely, Google said in its November security bulletin. The flaw, CVE-2026-58868, affects Android 14 through 17. Phones get the fix with security patch level 2026-11-01 or later, which phone makers and carriers send on their own schedules. As of November 4, Google's bulletin did not
Russian Police Arrest 3 Suspected VasyGrek Hackers, Dismantle Criminal Infrastructure
Russian authorities have arrested three suspected members of a threat group known as VasyGrek and dismantled its criminal infrastructure. Also known as Fluffy Wolf, the threat actor has a history of targeting Russian and international companies since 2016. The Ministry of Internal Affairs of the Russian Federation (MVD) said members of the group are "suspected of embezzling fun
