Google details new 24-hour process to sideload unverified Android apps
Summary
Google’s new sideloading flow adds a mandatory 24‑hour waiting period before a user can bypass the “unverified app” verification screen. The delay is intended to hinder high‑pressure social‑engineering scams that urge immediate installation; the extra time allows users to verify that the purported emergency is false. Users who prefer not to use the verification step at all can enable an “indefinitely” bypass once in developer options, then disable the options afterward. Google emphasizes that, with over 3 billion active Android devices—many serving as users’ primary computers—maintaining a balance between openness and security is essential to protect private data and sustain platform adoption. The approach reflects a shift toward longer‑term safety measures while still offering an opt‑out path for experienced users.

Full Disclosure: A Third (and Fourth) Azure Sign-In Log Bypass Found
Summary
The author details four distinct Azure Entra ID sign‑in log bypass techniques discovered between 2023 and 2025. GraphNinja (2023) validated passwords by targeting a foreign tenant, avoiding logs in the victim tenant; GraphGhost (2024) used an invalid client ID to fail post‑validation, hiding successful password checks. In 2025 the author uncovered GraphGoblin, which overflows the scope parameter with repeated “openid” entries, allowing token issuance without any sign‑in log entry, and a fourth bypass that overloads the User‑Agent header (≈50 KB) to suppress logging. All bypasses exploit insufficient input validation in the OAuth2 ROPC token endpoint, causing SQL column overflows that abort log insertion. Microsoft patched each issue, though the severity classification varied, with the latest bypasses fixed within weeks. Detection guidance includes KQL queries that join Graph activity logs with sign‑in logs on SessionId or SignInActivityId to flag sessions lacking corresponding log entries, requiring an E5 license for full telemetry.

How the Turner twins are mythbusting modern technical apparel
Summary
The Turner twins—identical genetic twins and professional adventurers—use themselves as a controlled experiment to compare contemporary technical apparel with historically accurate gear from the early 20th century. After Hugo’s near‑paralyzing C7 fracture, they began “time‑travel” expeditions, recreating vintage kits from 100 % natural materials (wool, silk, cotton, leather) by reviving dormant heritage manufacturers such as Crockett & Jones, which produced a multilayered leather‑and‑felt boot modeled on Mallory’s 1924 Everest shoe. Both twins wear ingestible temperature sensors, sweat‑analysis patches, and skin‑mounted hygrometers, generating data on core temperature, metabolic rate, moisture management, and cognitive performance.
Key findings: on a summit‑night simulation the modern‑down twin ran ~1.8 °C warmer than the historic‑gear twin, suggesting roughly one degree of thermal efficiency gain per 50 years. Natural fibers retained moisture better, preventing clamminess, but offered a narrower safe operating window, requiring active layer management. The twins conclude modern shells provide a safety margin for static conditions, while mastery of micro‑climate regulation remains the critical factor regardless of gear era.
