Microsoft Is Already Pulling Back On Its Windows Copilot AI Push

Microsoft is focusing on artificial intelligence in Windows amid user complaints about Windows 11, including issues with File Explorer, performance, and visual glitches. This shift coincides with the launch of Apple's budget-friendly MacBook Neo, which poses a threat to Microsoft's market share in the affordable laptop segment. Apple has a strong supply chain that allows it to offer a premium experience at lower prices. While Apple is developing its Apple Intelligence suite with limited AI tools and has partnered with Google to enhance Siri, it lacks a proprietary AI foundation model. Microsoft needs to ensure that new Windows 11 laptop owners, particularly those with budget models, do not experience performance issues or intrusive advertisements. The company has previously addressed user dissatisfaction after Windows Vista and Windows 8, raising questions about its ability to restore confidence in Windows 11.

“This was not opportunistic. It was precision.” — How North Korean hackers used Microsoft Teams and Slack to compromise Windows PCs with an elaborate ploy

On March 30, 2026, axios, a JavaScript HTTP client library, was temporarily compromised by suspected North Korean hackers who hijacked maintainer Jason Saayman's account. This allowed them to publish two malicious versions of axios on npm. The malicious versions were identified and removed within three hours by StepSecurity. A post-mortem blog on GitHub provided security measures for users of Windows, macOS, and Linux, highlighting risks from a Remote Access Trojan (RAT) introduced during the breach. The attack was attributed to a group known as UNC1069, which has been active since at least 2018. Two weeks prior to the breach, Saayman was targeted in a social engineering campaign where attackers posed as a legitimate company founder, leading him to install the RAT via a fake update during a Microsoft Teams meeting. Microsoft Teams was not compromised; it was used as a delivery method for the Trojan. Saayman noted the operation's sophistication.

Apple’s chips are the core of a new landscape, but its biggest win is Windows

Apple introduced its M1 Apple Silicon systems in late 2020, which received admiration but raised concerns due to a restrictive ecosystem. Over five years, Apple’s architecture has evolved, addressing challenges like gigabit Wi-Fi and high-speed expansion, yet it remains focused on desktops and laptops. The anticipated MacBook Neo, lacking an M-type System on Chip, has created apprehension within the Windows ecosystem. Currently, no Windows laptop can match the MacBook Neo in hardware quality and startup experience, while macOS offers a more tranquil workspace compared to the distractions of Windows 11. Apple has effectively utilized advancements in processor technology and manufacturing control to produce efficient chips and maintain a coherent ecosystem, making its products increasingly accessible. In contrast, Windows OEMs face challenges with component sourcing, build quality, and reliance on bloatware. There is potential for Microsoft to create a Windows Neo variant that meets user needs, while the sustainability of current business models for Windows OEMs is uncertain.

36 Malicious npm Packages Exploited Redis, PostgreSQL to Deploy Persistent Implants

Cybersecurity researchers have discovered 36 malicious packages in the npm registry that impersonate Strapi CMS plugins. These packages exploit Redis and PostgreSQL, deploy reverse shells, harvest credentials, and establish persistent implants. Each package consists of three files—package.json, index.js, and postinstall.js—without descriptions or repositories, and all use version 3.6.8 to mimic legitimate Strapi plugins. The malicious packages follow a naming convention starting with "strapi-plugin-" and were uploaded by four accounts within 13 hours. The identified packages include names like strapi-plugin-cron, strapi-plugin-database, and strapi-plugin-server. The malicious code is embedded in the postinstall script, executing automatically upon installation with the same privileges as the user. The payloads evolve from exploiting Redis for remote code execution to attempting direct PostgreSQL database exploitation and deploying persistent implants for remote access. The campaign appears to target cryptocurrency platforms, as indicated by the focus on credential theft and digital assets. Users of these packages are advised to assume compromise and rotate credentials. This incident reflects a broader trend of supply chain attacks in the open-source ecosystem, with recent examples including credential exfiltration payloads in GitHub repositories and compromised GitHub Actions workflows. Group-IB reported that software supply chain attacks are increasingly reshaping the cyber threat landscape, targeting trusted vendors and open-source software to gain access to downstream organizations.
