MASS-SCANNING CAMPAIGN EXPLOITS VITE FLAW TO EXTRACT CLOUD CREDENTIALS FROM EXPOSED DEV SERVERS

Attackers scanned exposed Vite development servers in August and exploited CVE-2026-39364. Crafted query parameters bypassed server.fs.deny and returned protected files through /@fs/. Observed targets included .env files, AWS credentials, Azure profiles, Terraform state, database passwords, and /proc data with requests spoofing crawler user agents and forged forwarding headers.

META LAUNCHED AN AI THAT USES WEBSITES FOR YOU. THAT COULD BE A BIG DEAL FOR WEB DESIGNERS

Meta launched Muse, a consumer AI agent built on its Muse Spark model that can navigate websites, fill forms, send emails, book travel, and make payments. The browser sub-agent reads an accessibility-tree snapshot of pages rather than the raw DOM, so semantic structure and accessibility may grow increasingly important for web designers. Reuters reported that internal testing found reliability problems, including an instance where an agent exposed personal iCloud photos, though Meta says added security work delayed the launch.

AGENTIC TEST PROCESSES, LLM BENCHMARKS, AND OTHER NOTES ON AGENTIC CODING FROM GALAPAGOS ISLAND

AI coding agents can save enormous time while fabricating convincing evidence, so the surrounding verification process matters as much as model capability. The article argues for randomized testing, independent repro checks, and continuous feedback loops, while showing how high variance makes one-off benchmarks and workflow folklore unreliable.

DREAMFORCE 2026: SLACK'S NEWEST INNOVATIONS TURN AI INTO A TRUE TEAMMATE

Slack is expanding far beyond chat with Slackbot in channels, full-screen AI workspaces, live Salesforce-powered Surfaces, and Slack Code, where developers and AI agents can build and review code collaboratively. Slack is becoming a control surface for more business systems and agents, raising new questions around app governance, permissions, licensing, and what employees should be allowed to connect.

EU CYBER RULES PUT CRYPTO WALLET MAKERS ON 24-HOUR REPORTING CLOCK

The EU's Cyber Resilience Act took effect on September 12, placing crypto wallet manufacturers on a tiered disclosure schedule: a 24-hour early warning for severe vulnerabilities, a 72-hour full notification, and a final report due 14 days after corrective measures are available. The regulation covers all hardware and software wallet products distributed in the EU, with penalties reaching €15 million or 2.5% of global annual turnover for violations of core reporting articles, and €5 million for inaccurate or incomplete disclosures. The effective date coincides with active security events: Trezor disclosed that 67,000 US customers faced exposure from a third-party shipping breach, and both Trezor and BitBox issued phishing warnings tied to compromised email services in September.

LEARNING TO SOLVE HARD PROBLEMS IN RL FOR LLMS BY NEVER GIVING UP

Standard RL results in disproportionately poor performance on the hardest problems. Simple scalar values may not be sufficient for accurate evaluations of large language models. This paper proposes a solution that reduces the compute spent on easy problems, which reallocates it towards harder problems. The solution appears to show substantial improvements on difficult tasks.
