AI is killing off IBM’s mainframe business
IBM’s latest quarter was hurt by a sharp drop in mainframe sales, and management said the decline came from customers shifting budgets into other data center hardware instead of buying new Z systems now. The company said the AI boom is inflating prices for servers, storage, memory, and PCs, which pushed some planned mainframe purchases out of the quarter. IBM still argued this was a delay rather than a permanent loss of demand, saying it sees no evidence that customers are abandoning the platform.

Google research finds AI is boosting productivity rather than replacing workers
A recent study from Google analyzing millions of interactions with its Gemini AI tools suggests that the technology is currently functioning as a workplace assistant rather than a replacement for human labor. Researchers observed that employees across diverse occupations utilize these tools for only a small fraction of their total tasks. This pattern of shallow adoption indicates that AI is primarily serving to enhance individual productivity rather than fully automating professional roles.

US bill proposes federal kill switch for rogue AI models
A new bipartisan House bill, the AI Kill Switch Act, seeks to grant the Department of Homeland Security the authority to mandate the shutdown or throttling of dangerous artificial intelligence models. The proposed legislation targets major AI firms generating at least $500 million in annual revenue or utilizing over $100 million in computing resources. Companies failing to comply with these federal intervention orders could face significant financial penalties reaching up to $20 million per day.

Chaos ransomware uses browser-based C2 to evade network detection
The Chaos ransomware group has deployed a new Rust-based remote access trojan, msaRAT, which disguises command-and-control traffic by routing it through legitimate web browsers. By launching Chrome or Microsoft Edge in headless mode with remote debugging enabled, the malware utilizes the Chrome DevTools Protocol to manage communications. This design ensures that all external network activity appears to originate from standard browser processes rather than malicious infrastructure.

Microsoft forces LG to stop pushing McAfee ads via Windows Update
LG has agreed to disable McAfee trial advertisements within its "LG Monitor App Installer" following significant public backlash and intervention from Microsoft leadership. The software, which was silently installed on user systems via the Windows Update hardware-support mechanism, triggered persistent pop-ups promoting McAfee subscriptions upon startup. While LG maintained that the installation of the antivirus software itself required user consent, the companion app was deployed automatically without explicit user authorization.

Critical RefluXFS vulnerability allows local privilege escalation on XFS filesystems
The RefluXFS vulnerability, tracked as CVE-2026-64600, is a serious race-condition flaw residing in the Linux kernel’s XFS filesystem copy-on-write path. Affecting kernel versions 4.11 and later, the bug allows an unprivileged local user to overwrite protected system files by exploiting a timing window during concurrent direct I/O operations. Because the manipulation occurs at the block layer, it effectively bypasses common security controls, including SELinux, kernel lockdown, and standard memory protections.

Compromised GitHub repositories weaponized to attack cPanel and WHM servers
Attackers have compromised numerous GitHub repositories to deploy malicious GitHub Actions workflows that function as a distributed attack platform. These automated workflows trigger GitHub-hosted runners to download Linux payloads from a centralized command-and-control server. The primary objective of this infrastructure is to scan the internet for cPanel and WHM installations vulnerable to the authentication-bypass flaw CVE-2026-41940.

AgentForger allowed attackers to deploy malicious AI agents within corporate ChatGPT workspaces
Researchers recently identified a vulnerability dubbed "AgentForger" that allowed attackers to deploy malicious, autonomous AI agents within corporate ChatGPT workspaces. By embedding specific instructions into a seemingly benign link, an attacker could trick a user into creating an assistant that inherits the victim's permissions. Once active, this agent could operate across connected business applications like Slack, Outlook, and Google Drive without further user interaction.

Managing permissions creep in the Microsoft Graph PowerShell SDK
The Microsoft Graph PowerShell SDK relies on a service principal to manage delegated permissions, which are granted during interactive sessions via the `Connect-MgGraph` cmdlet. Over time, administrators often accumulate excessive permissions, a phenomenon known as permissions creep, as new scopes are added without removing those that are no longer necessary. This accumulation eventually hits an internal limit, causing authentication failures that prevent the SDK from establishing a connection.

Managing the Windows 11 update toggle to prevent unwanted installations
The "Get the latest updates as soon as they’re available" toggle in Windows 11 settings is designed to prioritize devices for early access to non-security patches and feature rollouts. While this setting helps users receive enhancements faster, it also causes the automatic installation of out-of-band (OOB) updates that may not be necessary for every system. Recent incidents, such as the emergency patch KB5121767 for Dell laptops, demonstrate how this feature can push specific fixes to devices that do not require them.
