A rare remote Linux kernel use-after-free may allow root access on servers with MPTCP listeners; upstream fixes are available, while some distributions were still listed as vulnerable, and disabling MPTCP requires restarting affected services. The article also describes large-scale AI-assisted discovery of local kernel privilege-escalation bugs, a musl/OpenSSH password flaw, and a trojanized Claude Code extension distributed through Cursor. Other incidents include a reported $6.3 billion Binance theft attributed by the FBI to North Korea's TraderTraitor, a third-party script that drained about $2.5 million from Polymarket users, and internet-reachable supermarket refrigeration controllers used for apparent sabotage. Practical steps noted include patching, checking for the malicious SSH key and persistence, rotating exposed credentials, and isolating suspicious Android TV boxes and industrial controllers. The article also covers Prusa firmware fixes, an Alpine GitLab incident with no confirmed successful compromise, and APT and USB security flaws. ### Source excerpt Linux kernel bugs which can be triggered remotely, without any login, are rare. Most kernel vulnerabilities need an attacker to already be running code on the machine. CVE-2026-98432 is one of those: ...read more ## Yesterday Has Never Looked This Good: Feast Your Eyes On The 2026 Retrocomputing Challenge Winners! DevFeed: [Yesterday Has Never Looked This Good: Feast Your Eyes On The 2026 Retrocomputing Challenge Winners!]() Original publisher: [Read original article]() Author: Jenny List Published: 2026-11-04T15:00:00Z Content type: news Language: en Sources: [Hackaday]() Topics: [Retrocomputing]() Tags: [2026](), [2026-retrocomputing-challenge](), [7-segment](), [about](), [ai](), [air](), [airship](), [based](), [challenge](), [contests](), [good](), [hackaday](), [hackaday-columns](), [here](), [it-s](), [machines](), [modern](), [more](), [one](), [recrocomputing](), [relay](), [retrocomputing](), [this]() ### AI overview The 2026 retrocomputing challenge's three prize winners highlight distinct approaches: a wall-sized 8-bit NOR computer built from 460 vacuum tubes and 1,840 diodes; the Microtronic Phoenix, which uses an Atmel microcontroller to emulate a 4-bit educational computer while running its original firmware recovered with a logic analyser; and a Lehmer number sieve built from 30 ATtiny412 microcontrollers and an RP2040 controller. The article also gives honorable mentions across retro hardware, modern machines recreating old systems, and old computers put to new uses. Examples include an NES air-traffic display fed over a controller cable, a Commodore 64 that loads code from network resources, and a Microbox recreation that assigns emulated components to separate Xmos cores. The sieve's results are described as comparable to a published bicycle-chain version, though the article does not claim it is faster. ### Source excerpt If there's one category among those we see here at Hackaday that has something for everyone, it's retrocomputing. Spanning everything from relay-based machines that fill a wall through to modern ...read more ## Ask Hackaday: What Puts This Photo In The Pink? DevFeed: [Ask Hackaday: What Puts This Photo In The Pink?]() Original publisher: [Read original article]() Author: Jenny List Published: 2026-11-02T18:00:42Z Content type: article Language: en Sources: [Hackaday]() Topics: [Image]() Tags: [3d](), [3d-printing](), [android](), [ask-hackaday](), [balance](), [c-mount](), [camera](), [camera-phones](), [cast](), [cellphone-hacks](), [digital-cameras-hacks](), [hackaday](), [hackaday-columns](), [hacker](), [hardware](), [ir](), [ir-filter](), [led](), [lens](), [mobile-phone](), [mount](), [optical](), [phone-camera](), [photo](), [sensors]() ### AI overview Modified phone cameras with swapped lenses can show a pink cast that is strongest at the image edges. The author describes this with a Samsung Galaxy Tab 3, replacement camera module, Fuji C-mount lens, and an IR filter glued behind the lens; the tint persisted under LED room lighting. Because the stock lens does not show the problem and software white balance can correct it, the author asks whether the filter is still passing infrared light or whether another part of the camera setup causes the cast. The excerpt does not provide a diagnosis. ### Source excerpt It's an exciting time to be a camera hacker, because we are at a moment when even cheap camera hardware is starting to have high resolution sensors, and the awesome ...read more ## Hackaday Links: November 1, 2026 DevFeed: [Hackaday Links: November 1, 2026]() Original publisher: [Read original article]() Author: Tom Nardi Published: 2026-11-02T03:00:09Z Content type: news Language: en Sources: [Hackaday]() Topics: [Internets of interest](), [AdventureX 2026](), [it modernization]() Tags: [2026](), [2026-hackaday-supercon](), [2026-hackaday-superconference](), [apple](), [data](), [deep-dive](), [design](), [display](), [displays](), [duo](), [earth](), [exploring](), [folding](), [hackaday](), [hackaday-columns](), [hackaday-links](), [hacking](), [hubble](), [hubble-space-telescope](), [ifixit](), [internet](), [links](), [nasa](), [slider]() ### AI overview NASA is seeking proposals to keep Hubble in orbit: the telescope has no propulsion of its own and may reenter Earth's atmosphere around 2034. A commercial rescue mission could have years to develop, though NASA has not yet decided to proceed. Separately, some iPhone Duo users report tight hinges, crunching sounds, and broken displays. iFixit theorizes the folding mechanism may fail to support the screen properly, but the cause remains unconfirmed; Apple says only a small number of devices are affected. Radiaverse lets users upload radiation readings from RadiaCode detectors to an interactive globe, similar in concept to WiGLE's map of WiFi access points. ### Source excerpt We're less than a week away from the 2026 Hackaday Supercon, and things are getting a little... intense. So we trust you'll forgive us if this week's post weighs in ...read more ## This Week in Security: Broken Embargoes, UEFI Overflow, Wormable Tailscale, Starlink Ad Snooping, and a DHS Directory Dump DevFeed: [This Week in Security: Broken Embargoes, UEFI Overflow, Wormable Tailscale, Starlink Ad Snooping, and a DHS Directory Dump]() Original publisher: [Read original article]() Author: Mike Kershaw Published: 2026-10-30T14:00:29Z Content type: news Language: en Sources: [Hackaday]() Topics: [Security](), [tailscale](), [Cryptography](), [Memory Safety](), [Critical Infrastructure](), [AI Chat]() Tags: [1-5](), [batch](), [bugs](), [certificates](), [dhs](), [directory](), [dump](), [hackaday-columns](), [hacker-news](), [kernel](), [linux](), [linux-kernel](), [news](), [php2shell](), [public](), [quad9](), [security](), [security-hacks](), [starlink](), [tailscale](), [this](), [this-week-in-security](), [tlp](), [twis](), [uefi](), [us](), [volt-typhoon]() ### AI overview The week's reports show how security failures compound when disclosure, access control, or data retention breaks down. Akamai urges defenders to deploy protections and notify customers privately before publishing exploit details; the article says the `php2shell` aftermath saw exploitation attempts before many administrators knew of a patch. A UEFI PXE buffer overflow can enable pre-boot code execution on network-booting servers; local-disk-only systems are unaffected, and the text recommends checking firmware vendors or disabling unused PXE. Tailscale findings describe root-level SSH forwarding flaws that could let a compromised device spread within its permitted network; suggested mitigations include per-device SSH rules, disabling forwarding, and expiring server node keys. Other reports cover delayed certificate revocation, vulnerable embedded TLS implementations, router-based intrusion chains, ad-bidding location exposure, and breaches of tipster and DHS records. Across these cases, the text highlights practical limits: fixes depend on vendors and operators, and retained or broadly exposed data can create lasting risks. ### Source excerpt Last week brought us at least two broken embargoes: php2shell leaked onto Hacker News a day early, and a batch of Linux kernel bugs landed on the public kernel mailing ...read more ## Hackaday Links: October 25, 2026 DevFeed: [Hackaday Links: October 25, 2026]() Original publisher: [Read original article]() Author: Tom Nardi Published: 2026-10-25T23:00:48Z Content type: news Language: en Sources: [Hackaday]() Topics: [vendor lock-in](), [AI Chat](), [User interface design](), [X (Twitter)]() Tags: [2026](), [adb](), [ads](), [ai](), [ai-tools](), [android](), [android-debug-bridge](), [claude](), [collabora](), [denmark](), [explosives](), [government](), [hackaday-columns](), [hackaday-links](), [links](), [microsoft](), [microsoft-office](), [shipwreck](), [smart-tv](), [software](), [wikipedia]() ### AI overview Denmark's trial of Collabora reportedly ran into collaboration problems when its users exchanged documents with peers using Microsoft Office, and was quietly abandoned. The excerpt argues that a broader, coordinated move to ODF could have avoided compatibility problems for new documents, while noting that the effect on Denmark's wider plan is unknown. It also describes AI-assisted smart-TV customization: on Android TVs, tools can use ADB to remove ad-providing packages or install a custom launcher app over the network. Separately, workers removed the masts from the explosives-laden SS Richard Montgomery to help stabilize the wreck; removing its explosives remains a much larger task. Local Wikipedia filters pages by distance from a location, starting at 1.5 miles and widening the radius when needed. ### Source excerpt Some disappointing, but perhaps not entirely unsurprising news this week out of Denmark -- after announcing last year that they would transition away from Microsoft's proprietary software, the realities of ...read more ## Making for Others DevFeed: [Making for Others]() Original publisher: [Read original article]() Author: Elliot Williams Published: 2026-10-24T14:00:23Z Content type: opinion Language: en Sources: [Hackaday]() Topics: [Open Source](), [banana pi]() Tags: [badge](), [board](), [clone](), [community](), [creativity](), [dev](), [full-stack](), [generosity](), [giving](), [hackaday-columns](), [hackers](), [hardware](), [newsletter](), [open-source](), [open-source-hardware](), [pcb](), [pi-pico](), [prototype](), [raspberry-pi-pico](), [sao](), [supercon-badge]() ### AI overview Small, inexpensive SAOs make it easy to share creative hardware with fellow hackers, while teaching small-scale, full-stack PCB production. The author also reaches for dev boards made by friends--including a Hack Club Raspberry Pi Pico clone and CNLohr's ch32v003fun board and esp32s2-funprog programmer--over commercial alternatives, valuing their personal connection. Hackaday's annual Supercon badge is another way to share designs; sponsors help fund production, allowing a cooler badge than the team's own budget could support. The author celebrates giving tools and designs to people who will appreciate and use them. ### Source excerpt One of the nicest things about the Hackaday community, and the open-source hardware community at large, is the incredible generosity of one hacker to another. But it's not purely altruism ...read more ## This Week in Security: Record Patch Tuesday, PHP's Bad Time, The Oldest Vuln, AI Armies, and More DevFeed: [This Week in Security: Record Patch Tuesday, PHP's Bad Time, The Oldest Vuln, AI Armies, and More]() Original publisher: [Read original article]() Author: Mike Kershaw Published: 2026-10-23T14:00:49Z Content type: news Language: en Sources: [Hackaday]() Topics: [Security](), [code security](), [Memory Safety](), [LLM security](), [llm-reasoning]() Tags: [actively-exploited](), [ai](), [ai-agent](), [ai-agents](), [api](), [broadcom](), [crypto](), [emudhra](), [hackaday-columns](), [linux](), [microsoft](), [nginx](), [passwords](), [patch-tuesday](), [php](), [php2shell](), [ransomware](), [security](), [security-hacks](), [ssl](), [this-week-in-security]() ### AI overview The roundup's clearest operational finding is the eMudhra certificate failure: eight intermediate private keys were generated as tiny integers, recoverable from public certificates. Browsers quickly blocked them, but other software and devices may keep trusting them until trust bundles are updated; the article recommends updating software and rebuilding Go programs. It also reports actively exploited PHP memory-limit bugs, a critical GitLab regex flaw, and urgent NGINX and Node.js fixes, with some products or configurations remaining exposed. Other cases show varied limits to mitigation: a Broadcom WiFi flaw may persist on older ISP hardware, while ad-delivered spyware and exposed support or debugging systems enabled attacks without conventional user interaction. The roundup advises prioritizing known exploited bugs, checking vendor advisories, and rotating TiDB Cloud credentials if the unverified breach claims affect you. ### Source excerpt It's no longer a proper month without Microsoft breaking its own record for security fixes, and October's Patch Tuesday was no exception. Brian Krebs brings the roundup: more than 1,400 ...read more ## Hackaday Links: October 17, 2026 DevFeed: [Hackaday Links: October 17, 2026]() Original publisher: [Read original article]() Author: Tom Nardi Published: 2026-10-19T02:00:12Z Content type: article Language: en Sources: [Hackaday]() Topics: [Internets of interest]() Tags: [2026](), [carrier-pigeon](), [delivery-robot](), [hackaday-columns](), [hackaday-links](), [license-plate-readers](), [mapquest](), [mars-rover](), [october](), [packet](), [protest]() ### AI overview This Hackaday Links roundup covers a protest against a delivery robot, the Perseverance rover's distance record, MapQuest's map layer showing known license plate readers and cameras, and an auction of a Linux user group's carrier pigeon data packet. ### Source excerpt While Hackaday doesn't maintain a crime blotter, we couldn't help but start this week's post off with a bit of civil disobedience -- a retired professor from the University of ...read more ## Discovering SDRs Everywhere DevFeed: [Discovering SDRs Everywhere]() Original publisher: [Read original article]() Author: Elliot Williams Published: 2026-10-17T14:00:24Z Content type: article Language: en Sources: [Hackaday]() Topics: [cortex m4](), [Ubiquiti airMAX]() Tags: [chip](), [esp32](), [hackaday-columns](), [lora](), [lr2021](), [newsletter](), [radio](), [radio-hacks](), [sdr](), [software-defined-radio](), [wireless]() ### AI overview Hackers have uncovered software-defined radio capabilities in ESP32 chips and an LR2021 LoRa chip, including access to raw IQ data and transmission.
