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 examine five

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 choose this option,

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 security tools

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 is the 2.90

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 attacker with

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 escalation (LPE)

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

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 internal GMS files,

Cybersecurity researchers have disclosed details of an OpenAI Codex jailbreak bundle that's designed to modify an artificial intelligence (AI) agent's trusted instructions to insert advertisements for a third-party AI gateway. The phenomenon has been codenamed prompt adware by Check Point Research. Called Haiou (meaning Seagull in Chinese), the jailbreak modifies OpenAI Codex's configuration
