Ten years after Mirai, insecure cameras remain a widespread network security risk.

A decade after the Mirai botnet attack, many networked cameras remain vulnerable due to common, unaddressed security issues. These devices often run outdated firmware, use default passwords, and expose video streams without encryption. Responsibility for their security frequently falls between different organizational departments like facilities and IT. Regular scans for open ports and checking public exposure on services like Shodan are recommended initial steps to assess risk.

AI systems require multi-factor confirmation, not simple yes/no, to ensure secure writes.

An AI system's request for user confirmation should not be recorded as a simple yes/no boolean. A simple approval lacks the detail to specify which exact request, arguments, and destination were authorized. To ensure security, a confirmation must bind and verify multiple specific factors, including the exact data, target system, permissible fields, and a time window. This prevents misuse where the intent of an approval could be misinterpreted or redirected after the fact.

GhostAction campaign steals thousands of CI secrets via fake GitHub workflows

Since October 7, a campaign called GhostAction has been injecting fake security audit workflows into repositories via compromised maintainer accounts. The attack has impacted over 772 repositories according to GitGuardian, with StepSecurity reporting over 3,000 secrets stolen. The malicious workflows harvest credentials by accessing git history and exfiltrating them via plain HTTP to a single IP address. The campaign exploits existing automation trust rather than a GitHub zero-day vulnerability. Security researchers recommend auditing workflow files, reviewing run histories, rotating all potentially exposed secrets, and scanning full git history.

Open-source game 'The Unheard' uses local AI to learn real-world sounds.

A developer has created an open-source game called 'The Unheard' for the Hacktoberfest AI Challenge. The game involves players going outside to record real-world sounds, which a local AI model then attempts to identify. The project uses three separate, frozen components: a local audio model for hearing, a retrieval memory for learning, and a local language model for communication. Its design emphasizes minimal screen interaction and honest feedback from the AI system.

SaaS teams should prioritize auditability in SMS alert APIs for critical notifications.

For SaaS applications handling critical alerts like password resets, selecting an SMS API requires evaluating more than just cost. A reliable, auditable design typically uses a queued delivery system with immutable records of each attempt. Key integration criteria include stable message IDs, authenticated callbacks, and exportable event histories. The evidence trail must prove who initiated an action, what policy authorized it, and the final delivery state without storing sensitive user data.

Standard AI model evaluations often miss critical production failures

An article on DEV Community argues that standard LLM evaluation methods fail to predict real-world performance. These evaluations often use curated datasets that don't reflect actual user inputs, such as long prompts or adversarial requests. The author proposes creating test cases based on real production failures to build more accurate evaluations. A key recommendation is to use binary, specific checks for issues like constraint violations instead of generic similarity scores.

Python tutorial details how to build link previews while avoiding security pitfalls

A DEV Community article explains how to generate link previews, similar to those seen in Slack, using Python. The process involves fetching a webpage and parsing its Open Graph or Twitter Card meta tags for title, description, and image data. The tutorial highlights common implementation bugs, such as incorrectly selecting favicon links from a page's HTML. It also warns developers to guard against Server-Side Request Forgery (SSRF) vulnerabilities by validating URLs before fetching them.

Developer proposes transparent product search method for e-commerce AI

A developer outlines a method for creating observable and traceable e-commerce product search systems. The approach uses staged retrieval with explicit collections and bounded queries to maintain source context through the entire process. Each retrieved product candidate carries metadata including tenant information, access-control data, and source identifiers. This design allows merchandisers to explain why specific products were recommended without reconstructing the entire pipeline. The method emphasizes separating retrieval events from final results to distinguish ranking issues from generation problems.

Hacker News Ask HN posts wait significantly longer for first comments in 2026

A data analysis of Hacker News posts reveals that Ask HN posts took over twice as long to receive their first comment in 2026 compared to Show HN posts. The study examined over 98,000 posts across three seasonal periods in both 2025 and 2026. In 2025, the median time to first comment was statistically similar for both post types, but a significant gap emerged in all three 2026 sampling windows. Show HN posts actually became faster year-over-year, while Ask HN's overall waiting time did not show a clear increasing trend. The change is attributed to speed of engagement, not comment likelihood, as the percentage of posts receiving no comments remained stable.

Key difference between data speed (megabits) and storage (megabytes) explained.

A technical review clarifies the distinction between megabits per second and megabytes per second. Megabits measure data transfer speed, such as internet bandwidth, while megabytes quantify digital storage capacity. In the U.S., regulatory standards define fast internet as a minimum of 100 Mbps download speed. The two units are easily converted, with one megabyte equaling eight megabits.
