Here’s an overview of some of last week’s most interesting news, articles, interviews and videos:

r/opensource bans AI projects, and solo devs go down with them
Moderators of r/opensource, Reddit’s catch-all forum for open source software, have barred any project that “uses AI, is made by AI, or is intended for AI.” Moderator Wolvereness announced the rules in a post over the weekend.
AI slop is piling up highest on the biggest open-source projects
The maintainers of large open source projects are taking the worst of the AI slop. In a Linux Foundation survey of 234 open source contributors and maintainers, people running projects with more than 50 contributors estimated that close to a third of the code changes landing in their queue are low quality or AI-generated. Those maintainers now worry more about burning out than about the code itself.
Microsoft Authenticator vulnerability let rogue Android apps steal work account access
If you use Microsoft Authenticator on Android, update it. Researchers at Enclave found a flaw that let any app on your phone quietly take over your work account. The app didn’t need permissions, and you didn’t need to tap anything.
Several AI security market categories are headed for bigger platforms
In this interview with Help Net Security, Jonathan Care, Lead Analyst and Practice Lead AI at KuppingerCole Analysts, compares AI security startups to the early fraud market he helped define at Gartner. He explains which categories will survive as products and which will become features inside bigger platforms.
Private repos still leak secrets to Gheist, a stolen GitHub token campaign
Wiz Research has recovered more than 13,500 planted branches from 850+ compromised GitHub accounts, the work of a campaign it calls Gheist, after the user agent the tool sends with its GitHub API requests. The tool takes a stolen token, finds every repository that token can open, and plants a workflow in each one. The workflow prints the repository’s secrets into a log, and the attacker downloads it.
Bellini Capital CISO on AI security governance and the limits of patching faster
In this Help Net Security interview, Brian Blakley, CISO at Bellini Capital and ConnectSecure, explains why AI makes finding vulnerabilities faster while fixing them still takes time. He argues that “patch faster” is not enough and that teams need to cut exposure while remediation is pending.
CISA updates ScubaGear and ScubaGoggles, and says Microsoft 365 checks get faster
CISA released ScubaGear v2.0 and ScubaGoggles v1.1.0, new versions of the open-source tools it publishes to check Microsoft 365 and Google Workspace settings against its security baselines. The agency calls ScubaGear v2.0 the most comprehensive update to that tool since its 2022 launch. ScubaGoggles, which launched in 2023, gets a new baseline and enhanced Gemini controls.
GitHub’s npm package firewall can block brand-new versions before they install
GitHub announced a package firewall that checks npm packages against an enterprise’s policy before they install. It blocks known malware, critical vulnerabilities, and brand-new versions, and any developer can turn it on by pointing npm at the firewall.
Stolen staff logins are spreading attacks between K-12 school districts
Last school year, 808 K-12 school organizations got some unwelcome news. The Multi-State Information Sharing and Analysis Center (MS-ISAC) told them their staff accounts or credentials were circulating on underground and dark web marketplaces. That’s 808 of the center’s 6,116 K-12 members, and attackers are using those logins to get in the door and then reach the next district.
IT bosses are confident they’ve found the certificates they don’t know about
Forty percent of 500 senior IT and security leaders surveyed for certificate authority Sectigo said they are very prepared for monthly TLS certificate renewals because automated systems are already in place. Their more specific answers point elsewhere. Only 4% said their certificate management is already automated, and 61% said their organization had a certificate-related outage or incident in the past 12 months.
Qualys CISO on what security teams can do as exploit campaigns grow
In this Help Net Security interview, Nathan Smolenski, CISO at Qualys, talks about how security teams can handle the growing volume of AI-discovered vulnerabilities. He explains why CISOs should track the average window of exposure instead of standard MTTR, and why only a small share of disclosed flaws, under one percent in 2025, pose active risk.
Researchers broke the browsers built into VS Code, Cursor, Copilot, Codex and Claude Desktop
Forever Security found ways out of the built-in browsers in five AI coding assistants: Cursor, GitHub Copilot, OpenAI’s Codex, Microsoft’s VS Code and Anthropic’s Claude Desktop. In all five, a web page or a local file reached the computer behind the browser. Cursor ran attacker code, Copilot showed a fake address, and Codex, VS Code and Claude Desktop let a single local file read the rest of the disk.
Fake IT help desk callers got by on little more than names and email addresses
Attackers posing as IT help desk staff contacted employees by phone, email and Microsoft Teams in the third quarter of 2026 and talked them into opening remote access sessions, Cisco Talos Incident Response (Talos IR) found across several engagements. In one case, that access ended in ransomware.

Chinese hackers used VMware ESX zero-day; PHP2Shell and Fragnesia chained to root firewalls
China-nexus threat actors have exploited a VMware ESX zero-day to hide their tracks and chained PHP2Shell flaws with the “Fragnesia” Linux kernel bug to root servers and firewalls, cybersecurity researchers claim. Cisco has also confirmed that attackers are crashing its firewalls with a newly disclosed vulnerability.
LLM agent security needs more than guardrails
Madhu Shashanka, Chief Scientist at Concentric AI, explains why securing LLM tools and agents depends more on your data than on the model. Controls on model behavior, such as guardrails and injection detection, lower the rate of bad outcomes but never reach zero. Controls on what goes in are different, because you own the documents, systems, and credentials an agent can reach.
Product showcase: Stellar Cyber’s ISOC platform provides full-cycle architecture
An AI SOC that starts with somebody else’s alert is already too late. Stellar Cyber collects and normalizes telemetry, detects suspicious activity, correlates evidence, builds cases, investigates incidents, triages findings, and drives response from the same security architecture. That gives people and AI access to the evidence behind the alert – not just the alert itself.
I underestimated how fast security teams would trust AI to act in the SOC
For most of her career, Aqsa Taylor has watched enterprises adopt new security platforms slowly. She expected AI adoption in security operations centers (SOCs) to follow the same pattern, particularly given strict compliance requirements. Instead, adoption moved faster than she expected as AI helped attackers shorten the time between initial compromise and damage.
What exactly is ISOC? And what does it mean for you?
Security teams often spend too much time moving between tools to piece together an incident. Integrated Security Operations Center (ISOC) solutions aim to reduce that work by bringing detection, investigation, and response together, while SIEM remains the system of record for security data. Stellar Cyber’s approach uses the same underlying data throughout this process, giving analysts and AI access to the evidence behind an alert.
Security pros reckon the biggest AI risk comes with an employee badge
Employees pasting company data into AI tools worry security teams more than AI-powered attacks do. AI-generated phishing, the attack they run into most often, made the list of top concerns for only a quarter of the 209 security professionals O’Reilly surveyed in September.
