HN Top 10 — October 10, 2026
Today’s Top 10 on Hacker News
1. `123456’ password used in Danish CPR data breach
⭐ 81 💬 53 👤 baal80spam 🔗 Discuss on HN
A Danish IT company’s weak password security allowed hackers to access the country’s central CPR civil registration database, exposing data linked to about 8.8 million people. The breach involved at least three accounts, including an administrator, using the password “123456,” which experts called dangerously weak. The company confirmed its legal access to the register was abused, while the hacker said the information would not be sold or published.
2. REA Reverse – Engineer Anything
⭐ 451 💬 176 👤 modinfo 🔗 Discuss on HN
REA is a reverse engineering tool that lets a coding agent inspect, decompile, and explain how software works. It can analyze programs such as Windows Calculator or a browser game to recover logic like percentage calculations or speed acceleration. The goal is to understand, modify, or rebuild features by asking the agent in plain English.
3. Telegram Desktop vulnerability allowed any user’s file to be stolen
⭐ 191 💬 91 👤 g-b-r 🔗 Discuss on HN
A vulnerability in Telegram Desktop let an attacker craft a link that, when clicked, injected commands into the already running app through a local socket. The flaw abused an internal interpret URI scheme to read local files without confirmation and send them to an attacker-controlled chat, enabling arbitrary file theft and account takeover. The issue was fixed in Telegram Desktop 7.2.9.
4. Cloudflare acquires Deno
⭐ 1244 💬 632 👤 ilreb 🔗 Discuss on HN
Cloudflare has acquired the Deno team and will integrate its work with Cloudflare Workers and Durable Objects to build a simpler, scalable platform for server and distributed applications. The Deno runtime will receive bug fixes and security updates for one year before development ends, while Deno Deploy will shut down after six months and JSR will continue on Cloudflare infrastructure. This shift redirects future development toward a shared platform rather than a separate Deno runtime and hosting service.
5. Triple-A Minesweeper
⭐ 1014 💬 198 👤 robin_reala 🔗 Discuss on HN
Triple-A Minesweeper is a polished version of the classic Minesweeper game. It likely focuses on refined presentation and gameplay while keeping the familiar puzzle mechanics.
6. WSL3 Performance is about 5-60% faster than WSL2 depending on the workload
⭐ 53 💬 22 👤 tonymet 🔗 Discuss on HN
Benchmarks comparing WSL 3.0.2 with WSL 2.6.3 show that WSL3 delivers workload-dependent performance gains, with the largest improvements in memory bandwidth and scheduler/IPC latency. Kernel microbenchmarks report up to about 61% faster memory throughput and around 10-12% lower scheduling latency, while basic syscall speed improves only modestly. In a real Go compilation test, WSL3 completed the build about 4% faster overall, with a larger reduction in kernel time.
7. Eye of Sauron: Long-Range Hidden Spy Camera Detection (2024)
⭐ 169 💬 39 👤 ortusdux 🔗 Discuss on HN
ESauron is a proof-of-concept system for detecting hidden spy cameras by sensing electromagnetic emissions produced when camera memory processes video data. By intentionally changing the visual scene, it triggers measurable emission surges that reveal the presence and location of wireless, wired, or offline cameras. Experiments with 50 camera products showed 100% detection accuracy after four stimuli and reliable localization beyond 20 meters even with blockages.
8. Food processing influences metabolism and brain activity
⭐ 48 💬 29 👤 gmays 🔗 Discuss on HN
Researchers found that minimally and highly processed meals with nearly identical calories, macronutrients, water, salt, and weight produced different metabolic and brain responses. Ultraprocessed meals triggered greater insulin release, higher energy expenditure, less carbohydrate use, and altered activity in brain regions linked to motivation and reward. These results suggest food processing itself may influence metabolism and appetite, helping explain why ultraprocessed foods are associated with overconsumption and poor health outcomes.
9. Computers Cannot Make Decisions
⭐ 95 💬 80 👤 heavensteeth 🔗 Discuss on HN
The article argues that computer programs and large language models cannot make decisions, so blaming them for harmful outcomes is a form of decision laundering. Responsibility lies with the people and companies that choose to enable such behavior, even though economic interests discourage accountability and regulation.
